SHOULD YOU BUY PLASTIC PENS OR METAL PENS?
Описание: SHOULD YOU BUY PLASTIC PENS OR METAL PENS? Pens offer a useful and cost-effective way to promote your business, organization or event. Unlike sticky note cards or can coolie, pens slip into a person's pocket and see constant use. Plus, using pens to take notes actually helps people remember pertinent details. Of course, even buying pens can prove a process filled with decisions. One of the main choices you'll face is whether to get metal pens or plastic pens. Both kinds are readily available and have pros and cons. So let's jump in and see if we can't make choosing a little easier for you. COST OF METAL PENS Most people jump to cost as the first factor in their decision making, so we'll start there. On a per pen basis, you can get a basic plastic pen for around $0.44 and a metal pen for about $1.22. The catch is that most companies only sell in bulk and insist on minimum order quantities. 100 pens is a fairly standard minimum order size. So your base cost for 100 pens will run around $44 for plastic and $122 for metal ones. At close to three times the cost, metal loses this battle. That's assuming that price is the only concern. Plastic makes sense if a business owner just wants something her employees can write with that has the business name on it. Shelling out three times the cost doesn't make any sense. When cost isn't the primary concern, metal often makes more sense because the pens offer better durability. Say you're throwing a retirement party. Then you might opt for metal so your colleagues will have a keepsake to remember you by. PURPOSE The intended purpose of the pens also plays a role in the plastic vs metal pen decisions. For example, pens make a good promotional object to send out in mailers. They're small, light and fit in most size envelopes. You can put your logo, business name and website address on it. If you plan to send out 50-100 mailers to affluent leads, it's practical to pay the extra for economical metal pen. It creates a subliminal connection between your business and quality without putting a hurt on your wallet. If you plan to send out 5000 mailers to promote a sale at a retail outlet, plastic pens are far more practical. There's no need to create the subliminal connection. Retail products are commodity products, so there's no prestige issue. Using the per pen cost from above, metal would run you $6100 to plastic's $2200. Saving close to four grand on a retail sales promotion is the smart move. A different scenario is if you're buying pens for your personal use. Most people develop preferences for particular styles and materials in their pens. Some people prefer the heft of a fountain pen or a good metal one. Other people like cheap plastic ones they can lose without feeling bad. In those cases, comfort should drive your choice. BRANDING Strong businesses constantly seek ways to help cement their brands in customer minds. A brand is a strange combination of story, text, visual cues, and abstract ideas. The text and visual cues often go hand-in-hand, such as pairing up brand specific colors and taglines or logos. You've probably seen this in action with promo items that slap a logo onto a brand-color coffee cup. You can do the same thing using pens. This can prove a little hit or miss. The company you want to buy from may not have the exact shade of blue you use or may not offer color combos. Your logo and slogan offer salvation here. The whole point is to provide enough cues to trigger brand recall in the person. Pairing your logo and slogan with your business name a close color should prove enough to remind them of you. The more often someone gets reminded of your business, the faster they'll recall it when they need your services. The metal vs plastic pen debate comes up a draw here. It all boils down to which material you think sends the right brand message. A store that sells magic tricks won't get much brand mileage out of metal pens. An investment firm might lose brand value from plastic pens. IMPRESSION An area of concern that's related to branding is impression building. Let's say that you're a young lawyer. You got hired by a respectable, but unremarkable law firm. There are two levels of branding at work now. The firm has a brand that it wants to support and largely expects you to support. Within reason, you need to operate inside those expectations. Then there is your personal brand. It's entirely possible that you want your brand to be distinct from the firm's brand. Let's say that the firm issues plastic pens with firm's name on it to everyone. Those send the message of practical and affordable. A simple way to set your brand apart from firm's brand is to order metal pens with your name and the firm's name on it. That sends the impression that you offer a higher level of quality. A tactic like that keeps you inside the bounds of the firm's branding. At the same time, it lets you start creating a separate brand identity of your own. On the other hand, let's say you work at a business that doesn't use branded pens. Plastic pens that note your name, position and phone number set you apart without stepping on the business brand. For impression building, the choice between metal pens and plastic pens is all about context. You want to offer something that makes you a little more memorable without stepping on toes. PARTING THOUGHTS ON PLASTIC VS METAL PENS The choice between plastic and metal pens doesn't offer many certain answers. If the price is the final deciding factor, plastic pens will always be cheaper. If a feeling of quality is the deciding factor, metal typically wins. Beyond that, the decision becomes a matter evaluating the context. You need to consider which material sends the right message for the audience. Does it support your personal branding effort? Does the perceived benefit of one material outweigh the difference in cost? Once you can answer those questions, though, you should know which to buy. Ballpoint Pen A ballpoint pen is a writing instrument which features a tip that is automatically refreshed with ink. It consists of a precisely formed metal ball seated in a socket below a reservoir of ink. As the pen is moved along a writing surface, ink is delivered. Even though ballpoint pens were first patented in the late nineteenth century, they only started to reach commercial significance in the early 1950s. Now, ballpoint pens dominate the writing instrument market, selling over one hundred million pens each year worldwide. History While the idea of a ballpoint pen had been around for many years, it took three different inventors and almost 60 years to develop this modern writing instrument. The first patent for this invention was issued on October 30, 1888, to a man named John J. Loud. His ballpoint pen consisted of a tiny rotating ball bearing that was constantly coated with ink by a reservoir above it. While this invention worked, it was not well suited for paper because it leaked and caused smearing. Two other inventors, Ladislas Biro and his brother Georg, improved on Loud's invention and patented their own version, which became the first commercially significant ballpoint pen. These pens still leaked, but not as badly. They became popular worldwide, reaching the height of sales in 1944. The next year another inventor, Baron Marcel Bich, finally solved the leakage problem and began manufacturing Bic pens in Paris. Over the years, many improvements have been made in the technology and quality of the various parts of the pen, such as the ink, the ball, the reservoir, and the body. Background The ballpoint pen was developed as a solution to the problems related to writing with a fountain pen. Fountain pens require the user to constantly refresh the pen by dipping its tip in ink. This is not necessary with a ballpoint pen because it is designed with its own ink reservoir, which uses capillary action to keep the ink from leaking out. At the tip of the pen is a freely rotating ball seated in a socket. Only part of this ball is exposed; the rest of it is on the inside of the pen and is constantly being bathed by ink from the reservoir. Pressing the tip of the pen on the writing surface causes the ball to roll. This rolling action then transfers ink from the inside of the pen to the writing surface. While different designs of ballpoint pens are available, many of the components are the same. Common components include a ball, a point, ink, an ink reservoir or cartridge, and an outer housing. Some pens are topped with a cap to prevent it from leaking or having its point damaged. Other pens use a retractable point system for the same reason. Here a small spring is attached to the outside of the ink reservoir, and when a button is pushed, the point is either exposed or retracted. Still other varieties of ballpoint pens have multiple ink cartridges, making it possible to write in different colors using one pen. Other pens have refillable ink cartridges. One type of pen has a pressurized cartridge that enables the user to write underwater, over grease, and in space. Raw Materials A variety of raw materials are used for making the components of a ballpoint pen, including metals, plastics, and other chemicals. When ballpoint pens were first developed, an ordinary steel ball was used. That ball has since been replaced by a textured tungsten carbide ball. This material is superior because it is particularly resistant to deforming. The ball is designed to be a perfect sphere that can literally grip most any writing surface. Its surface is actually composed of over 50,000 polished surfaces and pits. The pits are connected by a series of channels that are continuous throughout the entire sphere. This design allows the ink to be present on both the surface and interior of the ball. The points of most ballpoint pens are made out of brass, which is an alloy of copper and zinc. This material is used because of its strength, resistance to corrosion, appealing appearance, and ability to be easily formed. Other parts, like the ink cartridge, the body, or the spring can also be made with brass. Aluminum is also used in some cases to make the pen body, and stainless steel can be used to make pen components. Precious metals such as gold, silver, or platinum are plated onto more expensive pens. The ink can be specially made by the pen manufacturer. To be useful in a plastic ballpen, the ink must be slightly thick, slow drying in the reservoir, and free of particles. These characteristics ensure that the ink continues to flow to the paper without clogging the ball. When the ink is on the paper, rapid drying occurs via penetration and some evaporation. In an ink formulation, various pigments and dyes are used to provide the color. Other materials, such as lubricants, surfactants, thickeners, and preservatives, are also incorporated. These ingredients are typically dispersed in materials such as oleic acid, castor oil, or a sulfonamide plasticizer. A little about the plastic in our pens With pens it's hard to avoid not using plastic, so we've done our research and made sure that the plastic we use has the least damage to the environment. An eco pen club pen is up to 85% less plastic than a traditional pen. Our plastic is safe & easy to recycle The majority of plant-based plastics who claim to be 'biodegradable' only break down in very strict conditions. Our plastic can be placed in household recycling bins. Our plastic is easy to sort in recycling plants Plant-based plastics (which we don't use) are not easy to sort in recycling plants and shouldn't be put in mixed plastic recycling bins.

Why you shouldn’t wear slippers while you’re working from home
Описание: Why you shouldn’t wear slippers while you’re working from home Having a presentable set of pajamas to hang around in is key—so why should your slipper game be any different? One of the biggest accessory trends of the spring 2021 season was the slipper shoe, so now is as good a time as any to complete your at-home loungewear look with a pair of luxurious slip-ons from one of these six styles of the best slippers for women. You may have already invested in a pair of house shoes, but those who have yet to pamper themselves—and their feet!—with a warm and toasty slip-on might consider snagging one of these this holiday season. Think of it as a retreat for your feet, and there’s a handful of slipper personalities for the homebody at heart. How about a luxurious pair of sherpa mules or plush slides, which are perfect for those with no plans to leave the house at all, or perhaps ultra-chic suede slip-ons from Khaite or Charvet—two styles so chic you’ll want to wear them out of the house. You can also mentally escape from your home and check in to Hotel Loro Piana with its fabulously luxe checked version of the hotel-inspired slipper. Fashion maximalists might gravitate toward Bottega Veneta’s spongy bath slides, while the minimally minded would be more than happy in Everlane’s quilted duvet slippers. Or play dress-up with a pair of pom-pom-adorned smoking slippers or boudoir-inspired satin slip-ons. All of which would make equally great holiday gifts. Whether it’s before bed, weekend mornings, or all day (we won’t judge), give your feet the comfort they deserve in one of these pairs of the best women's slippers. You might want to give your working-from-home uniform – sweatpants on the bottom, Zoom-appropriate on top, slippers on feet – a tweak. An expert has warned against wearing slippers day-in, day-out while working from home, suggesting your indoor shoes could damage your posture, pain, and overall health. Eleanor Burt, also known as Posture Ellie, is a posture alignment therapist. She tells Metro.co.uk that going barefoot is the best thing you can do for your feet in lockdown. She explains: ‘While slippers will certainly cause you fewer problems than the restrictive, supportive and heeled shoes most people wear most of the time (the majority of ‘normal’ high street shoes and trainers are all three of these things), slippers still serve a role in switching off the muscles and proprioceptors of the feet. This contributes to lazier and less balanced feet. ‘This essentially means the foundations of your body are off and this then feeds up the rest of the body and impacts how the rest of your body moves too. ‘We are all very indoctrinated into the rhetoric that our feet ‘need support’ and ‘need protection’, but actually by supporting and protecting our feet, we create extremely weak, stiff feet that don’t move as they are designed to. ‘This really has a significant impact that shouldn’t be scoffed at. ‘You know when you see older people shuffling around in their slippers, barely able to lift their feet off the floor? A big contributor to that will have been their footwear choices (and chair sitting).’ What Is a Shoe Rack? A shoe rack is a storage unit designed for holding shoes. Shoe racks may be free-standing to place inside a closet or may be built into a closet organizer system. The right type of rack for you depends on the number of shoes you have to store and where in your home you want to store shoes. Many people who have a large shoe collection have built-in racks in their bedroom closets. Each rack may hold several pairs of shoes. Some shoe racks are slanted wooden boards that have a strip running across the back to rest the heels of the shoes on so that the shoes are displayed for easy selection. Other types of shoe holders are white metal stackable shelves that are either part of a closet shelving system or are a part of a free-standing rack. With the shelf type, you can just place pairs of shoes on the shelves side by side. Some kinds of shoe racks have curved wire loops that you place the shoes over.A shoe rack is an alternative to shoe boxes. Clear acrylic shoe boxes that each hold one pair of shoes can be stacked anywhere and some people prefer to use these for shoes not worn too often. Shoe boxes may be stored up high in a closet, while the racks are usually on the floor or at eye level to allow easy access to the shoes. Why Non-woven bags is Eco- Friendly ? Now that everyone has understood that plastic bags are non-biodegradable, the use of non-woven bags have become of primary importance. Even a non-woven bags manufacturer would tell you that it would be best to opt for these bags instead of plastic bags as they are eco-friendly. So what is exactly the reason ? Let's find out. 1) No harmful soot while burning When you burn a normal bag, you notice there are a lot of soot and ash and also the smell of smoke. With non woven bags, there will not be any kind of toxic contaminants when you burn them. Since they are biodegradable in nature, the leftovers of the burn will get dissolved in the soil. 2) Recycle and reuse Non-woven bags are known for this feature and you can safely use these bags over and over again. 3) Very cost effective The simpler the bags, the better it is for the environment. Additionally, you should also consider the fact that these bags can be recycled and reused. So, even if you invest in the bag, it will be a one-time investment as you can recover the cost by reusing it. 4) Greater durability The easiest way to understand the concept of reuse is by observing the number of times you can use the product without having to spend on something similar. Non-woven bags are just the perfect example of that. They are extremely durable making them easily reusable for further needs. Unlike plastic or other bags, the chances of these bags to wear down with age is quite slim. The good news is that CaCO3 Filler Masterbatch can be used for Non-woven bags, which can be added up to 65%, help to reduce resin significantly. Many major cities and corporations are cracking down and banning plastic bags in an effort to reduce pollution and save our oceans. But is that really the best approach? While plastic bags are “almost certainly the worst” of all options in terms of ocean pollution, according to Quartz, the issue gets a little murkier when you take other environmental issues into consideration. As it turns out, canvas bags might be less eco-friendly than plastic bags because they’re often made of cotton, which requires more energy and water to produce. According to one study from 2011, a cotton bag’s carbon footprint is 598.6 pounds of CO2, compared to 3.48 pounds for a standard plastic bag made from high-density polyethylene. Researchers concluded that it might actually be better to reuse those plastic bags you get from the supermarket, then recycle them once they’re no longer viable. Similarly, a 2018 recent study from Denmark found that low-density polyethylene bags wreaked the least damage on the planet of all the different types of bag studied. (However, it’s important to note that ocean pollution was not taken into account in that particular study, and that plastic can still severely harm marine life and ecosystems.) Representatives of Denmark's Ministry of Environment and Food determined that conventional cotton bags would have to be reused 7100 times to match the cumulative environmental performance of a plastic bag. Organic cotton bags are even worse, because those would need to be reused 20,000 times. Backpacks were once considered casual and suited only for travel or for students who needed to lug books by the kilos. It was a hard-working bag meant for the wearer’s comfort. But as offices become more mobile with laptops and assorted gadgetry (chargers, tabs, power banks and mobile phones), a backpack has become the goto workbag. Add to this the rise of a casual corporate culture, where athleisure is kosher at the workplace and sneakers are subbing in for high heels for women and dress shoes for men, and backpacks are strictly formal now. Making and selling backpacks and travel bags — of burlap and vegan leather — is how Samriddh Burman, Karuna Parikh and Rewant Lokesh of Kolkata came together to start The Burlap People.

Optimal Selection of Leveling Agent for Paints and Coatings
Описание: Optimal Selection of Leveling Agent for Paints and Coatings Finding the right leveling agent is often a tedious process, considering all the parameters. It is important to check dosage and product variations to figure out the correct chemistry and fine tune the formulation. Make the selection of your leveling agents easy for your coating formulation by getting answers to most of your questions that arise during the selection process. Learn the role of solvents and other important factors in leveling and, thus, come up with the best coating product. Dyeing auxiliaries are defined as chemicals or formulated chemicals which enables a processing operation in dyeing to be carried out more effectively. Dyeing auxiliary includes dye fixing agents, cationizing agent, dispersing & leveling agents etc. They help in stabilizing the dyeing bath to improve the exhaustion, achieve level dyeing and improve fastness properties. Need for Leveling Agents It is admitted for many paints that a perfect appearance means also a perfect leveling. Poor leveling (like orange peel or ghosting) may not influence significantly the paint parameters in time, as it is more aesthetic orientated. But the leveling agent itself may cause some severe issues. A correct leveling agent helps in reaching the wanted leveling and final film finish. But a wrong choice may lead to surface defects such as craters, pinholes, loss of gloss or even inter-coat adhesion problems. Therefore, to understand the leveling, it is important to understand the influence of the surface tension on the paint and finding a balance is critical: Too low surface tension may be good for the substrate wetting but may lead also to a wavy surface. Too high surface tension can cause adhesion and surface wetting issues. If you are exploring the factors that govern leveling in any formulation, it might be worth to begin with an in-depth understanding of leveling basics (surface tension, contact angle, test method, etc.) at first. Which leveling agent is suitable for your formulation? There are several base chemistries to choose from when selecting a leveling agent & lower the surface tension to the point just that you need for a desired application. The most common types of leveling agents are listed below. Silicone-based agents (Polydimethylsiloxane modified - PDMS) Acrylate-based agents (Polyacrylate) Fluorocarbon-based agents (Modified Fluorocarbons) Hydrocarbon-based leveling agents: less efficient than previous families Understand each chemistry in detail and see which one fits best for your formulation & end-application needs. Silicone oils are important tools in vitreoretinal surgery and their introduction has represented a pivotal moment in the management of ophthalmic surgery as they are equipped with a combination of chemical and physical properties that have propelled their surgical use. Silicone oils are essentially used as intraocular tamponade thanks to their ability to maintain the adhesion between retina and retinal pigment epithelium (RPE). The safe and effective use of tamponade substances means the knowledge of their physical and chemical properties because it is on the basis of this knowledge that surgeons have to decide what type of tamponade they should use. What is the function of softener flake softener for textiles Softener flake is an important finishing process in printing and dyeing. It is also a chemical substance that can change the static and dynamic friction coefficient of the fiber. So what is the effect of softer flake on textiles? Here is a brief introduction. When the static friction coefficient of the fiber changes, the hand will feel the smoothness of the fiber, reduce the friction between the skin and the fiber, and it is easy to move on the fiber or fabric; when the dynamic friction coefficient of the fiber changes, the microstructure between the fibers It will move and deform, and you can feel that the dynamic and static friction coefficient changes smoothly. In the textile processing process, after many treatments, the fabric and the machine will directly rub against, easily damage and wipe the fabric and fiber, making the fabric and fiber feel rough, the general synthetic fiber feels worse, especially the microfiber fabric. In order to make the fabric soft, smooth and comfortable, the fabric needs to be finished. The widely used fabric is treated with softer flake, which can make the fiber itself soft and smooth, meet the processing conditions, and avoid damage during processing. Therefore, it is also an important auxiliary for textiles. The above is an introduction to the effect of softer flake on textiles. Thank you for your patience to read.

Acrylic Resins Acrylic resins feature excellent transparency and durability, and are used in a broad range of applications from consumer items like lenses to industrial products like molding materials, coatings and adhesives. About Acrylic Resins Acrylic resins feature excellent transparency and durability, and are used in a broad range of applications from consumer items like lenses to industrial products like molding materials, coatings and adhesives. In addition, acrylic resins are also used in other areas, such as binders for paper/fiber processing, PC screens, display windows for cellular phones and light guide panels for liquid crystal display (LCD) backlights. Due to their excellent durability and weatherability as coating materials, acrylic resins are used extensively in applications such as automotive, architectural and plastic coatings. Acrylic resins have the below general characteristics. ? Appearance (gloss, build) ? Weather resistance ? Adhesion ? Transparency ? Hardness ? Heat resistance ? Chemical resistance ? Water resistance ? Workability WHAT IS A DEGREASER? A degreaser is a cleaner designed to remove grease, oils, cutting fluids, corrosion inhibitors, handling soils, fingerprints, and other contamination common in assembly, stamping and other metal fabrication in refineries, motor repair shops, airplane hangars, and factories, etc.. Degreasers go by a number of different names including precision cleaner, maintenance cleaner, as well as several specific for automotive repair such as carb cleaner or brake cleaner. The objective for a degreaser is to remove the offending soil quickly, avoiding as much wiping and scrubbing as possible. Degreasing solvents are commonly packaged as an aerosol for convenience. Aerosols have the added advantage of providing a forceful spray that creates agitation and which penetrate small crevices. Water-based degreasers are common in a trigger sprayer, or in gallon or drum containers for immersion or batch system cleaning. Specialized equipment like ultrasonic or vapor degreasers are available for more automated cleaning. These processes are repeatable, so better suited for more critical cleaning applications, like aerospace or medical appliance maintenance. Techspray offers a large selection of degreasers and maintenance cleaners under the G3?, E-LINE?, PWR-4?, and Precision-V brands, which range from economical heavy-industry cleaners to high precision solvents for sensitive components. WHY DO I NEED A DEGREASER? Dust, dirt, grease, and oxidation contamination can cause corrosion, slipping hazards, overheating, increase electrical resistance in contact areas, and many other issues. Degreasing may be required to prep for down-stream processes like painting or plating. Cleaner Degreasers can clean oil, grease, oxides and handling contamination from equipment and assemblies that include: Metal and fiber optic cable splices Motors and transformers Programmable Logic Controllers (PLCs) Pneumatic and hydraulic assemblies Electronics and electrical equipment Meters/measurement devices Industrial-strength degreasers are needed to remove grease, tar, asphalt, oil, and grime in these kinds of applications: WHAT IS THE DIFFERENCE BETWEEN A DEGREASER AND A CONTACT CLEANER? Degreasers are intended to remove oil, grease, oxides and handling contamination from equipment and assemblies, while a contact cleaner does the same thing specifically for electrical contacts. A contact cleaner (also called electrical cleaner, switch cleaner, electrical contact cleaner, and (specific for automotive repair) battery terminal cleaner removes contamination from electrical contacts, the conductive surfaces of connectors, switches and other electrical and electronic components with moving surface contacts. WHAT DO I LOOK FOR WHEN SELECTING A DEGREASER? There are several factors that can have a big impact on performance and safety in choosing the proper degreaser for a given application in an environment: Flammability – Degreasers often contain very flammable alcohols and hydrocarbon solvents. They can be cheap and effective, but can be dangerous without proper ventilation, or around open flames, sparks (e.g. from welding), or hot surfaces. Nonflammable degreasers avoid these safety issues but are generally more expensive. In addition, some nonflammable cleaners can be very toxic, containing hazardous solvents like Perchloroethylene, trichloroethylene or n-propyl bromide. High flashpoint (often called “high flash”) solvents have vapors that are less likely to combust in normal ambient temperatures (say below 140°F/60°C). Dielectric strength – If you plan to work on powered equipment, or need to switch it on before the solvent has flashed off, consider a degreaser with a high dielectric strength. Make sure you know the amperage and voltage of the circuits you are trying to clean before spraying anything onto the circuits, and evaluate the suitability of any cleaner in your application. Dielectric strength is the maximum electric field that the material can withstand before its insulating properties break down. The lower the dielectric strength, the more likely it will breakdown and allow electricity to flow through and short out. Plastic / rubber compatibility – Care needs to be taken when cleaning plastic or components, rubber gaskets and seals. If the degreaser is incompatible with the plastic, it can craze (create small cracks), embrittle, or soften the material. Rubber seals may swell, shrink, or dissolve. A new degreaser should always be tested before being used broadly. Toxicity – N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. There are documented court cases where workers suffered major health effects when exposed to high levels of these chemicals. Workers reported headaches, dizziness, and even loss of full body control. There are also possible links to reproductive problems and cancer. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher. Environmental issues – Volatile organic compounds (VOCs), solvents that add to smog, or solvents with high global warming potential (GWP) have been a focus of regulators. Some state (e.g. CARB, the California Air Review Board), municipal, and even industry-specific regulations restrict the use of high VOC or high GWP materials.

Understanding USB Cable Types and Which One to Use Most computers and electronic
Описание: Understanding USB Cable Types and Which One to Use Most computers and electronic devices have some form of USB connection, and many devices also come packaged with a USB cable. What are all these different cables for, and why does it matter which one you use? It can be somewhat complicated to wrap your head around all this. Here's everything you need to know about the USB standard, including how to identify various USB cable types and what they do. 6 Common USB Cable Types and Their Uses USB is supposedly universal, but there are so many different types of USB cables and connections. Why is this? As it turns out, they each serve different functions, mainly to preserve compatibility and support new devices. Here are the six most common types of USB cables and connectors: Type-A: The standard flat, rectangular interface that you find on one end of nearly every USB cable. Most computers have multiple USB-A ports for connecting peripherals. You'll find them on game consoles, TVs, and other devices too. This cable only inserts in one way. Type-B: An almost-square connector, mostly used for printers and other powered devices that connect to a computer. They're not very common these days, as most devices have moved onto a smaller connection. Mini-USB: A smaller connector type that was standard for mobile devices a while back. While not that common today, you'll still see these on some devices, which are mostly from Sony. These include cameras, the PlayStation 3 controller, MP3 players, and similar. Micro-USB: Another past standard, slowly declining in popularity, for mobile and portable devices. It's even smaller than mini-USB. While you'll still find micro-USB on some smartphones, tablets, USB battery packs, and game controllers, many have moved onto USB-C. Type-C: This is the newest type of USB cable. It's a reversible connection that packs higher transfer rates and more power than previous USB types. It's also capable of juggling multiple functions. You'll see it on many modern laptops and smartphones, including MacBooks, Pixel phones, and controllers for the PlayStation 5 and Xbox Series S|X. We discuss USB-C more below. Lightning: This isn't a true USB standard, but is Apple's proprietary connector for the iPhone, AirPods, some iPad models, and more. It's a similar size to USB-C and comes standard on most Apple devices released since September 2012. Older Apple devices use the much larger 30-pin proprietary connector, and newer iPad Pro models use USB-C. We've covered more on cables, adapters, and ports for Apple devices if you're curious. In most cases, you'll find USB cables have one standard type-A end and one type-B end of some sort. The type-A end powers the device, while the type-B end receives power. This is to prevent potential damage that would be caused by connecting two computers via USB-A, for example. The Mini and Micro connectors are considered smaller forms of type-B, even though "type-B" is usually not in their name. In general, the cables you'll use the most, and therefore need to replace, are micro-USB, USB-C, and Lightning. USB Speed Standards USB connection types are only half the story, as USB has also gone through multiple standards of varying data transfer speeds. The cable's connector doesn't necessarily mean that it uses a certain standard. The main iterations of USB's speed are: USB 1.x was the original standard, and is ancient by modern benchmarks. You're very unlikely to find devices using this standard nowadays. USB 2.0 introduced many modern USB norms, including support for Mini and Micro cables, USB OTG (see below), and more. It's the slowest speed of USB still used today. You'll find it used on cheap flash drives, devices like mice and keyboards, and similar. Most computers still include a few USB 2.0 ports. USB 3.x is the current standard for USB speeds. It's much faster than USB 2.0, and thus recommended for devices like external hard drives. You can typically identify a USB 3.x port or connector by its blue coloring. Some USB 3.0 ports also have an SS symbol (which stands for Super Speed). Most new computers have at least one USB 3 port, and high-quality flash drives use this standard. USB 4.0 is the newest standard, but at the time of writing it's not generally available. It will become the norm over the next several years, just like it took USB 3 a while to catch on. What are DisplayPort Cables? DisplayPort cables are used to provide video and audio connectivity between a host device (typically a PC) and a display. They are commonly used yet are relatively simple in design, with all DisplayPort cables featuring the same basic layout. In the simplest terms, DisplayPort cables are designed to provide both audio and video signals via a single cable. They are used to connect displays or monitors to a source device such as a PC or laptop and transmit the outputted audio and video data to the display. DisplayPort connectors feature twenty pins fitted into an L-shaped connector. Many also include a locking mechanism to ensure a secure connection and prevent the connector from loosening or accidental disconnection. How Does DisplayPort Differ from HDMI? Both HDMI and DisplayPort are digital systems, originally designed to replace older analogue systems such as VGA. They both have the same purpose – to transmit high-definition digital audio and video to a display from a source device – but this does not mean that they are the same. There are understandably some key similarities between the two, such as image quality, but their differences should not be overlooked. DisplayPort and HDMI cables are intended for different purposes, feature different connectors, and cannot be used interchangeably. DisplayPort is primarily used on PCs, laptops, and tablets for video transmission. Unlike HDMI, it is very rarely used on consumer electronics. Another key difference is that DisplayPort is subscription-free for producers, whereas HDMI must be licensed by the manufacturer. There are also several additional features which make it easier to differentiate between the two. DisplayPort offers the functionality to drive more than one display with a single cable, making it highly useful for professional applications. Conversely, HDMI can only drive a single display per cable. However, HDMI can support an ARC (Audio Return Channel) which allows sound to be sent from the display to the source device. DisplayPort does not offer this capability. DisplayPort Cable Lengths DisplayPort cables are available in a variety of lengths to suit different applications and user requirements. There is no specified DisplayPort cable length limit and no maximum length for these cables, meaning that it is possible to get cables up to 50m in length. Additionally, all cables up to two metres in length must support HBR2 speeds (21.6Gbit/s). An incident where three men allegedly cut an undersea cables raises the question of how vulnerable the world's submarine internet cables are to damage, whether intentional or accidental. An HDMI cable is just a conduit between your TV and media device, be it a DVD, Blu-ray, or 4K UHD Blu-ray player; media streamer; video game console; or PC. Different types of HDMI cables do exist, but their designations indicate how much data they can carry. (Spoiler: There’s really no such thing as a 4K HDMI cable.) When pared down to the most basic information, the video resolution guidelines—as set by the HDMI Forum Technical Working Group that defines the specification—are: Standard HDMI: Up to 720p or 1080i resolution at a 30Hz refresh rate High Speed HDMI: Up to 4K resolution (including 1080p) at 30Hz Premium High Speed HDMI: Up to 4K resolution with high dynamic range (HDR) at up to 60Hz Ultra High Speed HDMI: Up to 10K resolution with HDR at a 120Hz refresh rate (4K video can refresh at up to 240Hz) The more detailed versions of the guidelines matter if you want more than just a basic TV signal: If you play video games at more than 30 frames per second, for example, or you intend to make full use of an HDR TV, or you want an HDMI cable that can also carry data over ethernet (most people do not, but that bandwidth can be used for other things). For these types of scenarios, you must take refresh rate (measured in cycles per second, stated as Hertz, and abbreviated as Hz), the level of color precision (aka color depth, measured in bits; e.g., 8-bit, 10-bit, or 12-bit), and color data compression (i.e., chroma subsampling) into consideration. The higher you go with refresh rate and bit depth—and the less color data compression you opt for—the more data that will be pushed to your TV. Accordingly, you’ll need an HDMI cable that has adequate bandwidth. The chart below details the nuances that divide Standard HDI, High Speed, Premium High Speed, and Ultra High Speed HDMI. A Premium High Speed HDMI cable should cover the highest demands you’d ask of a 4K TV with a 60Hz refresh rate. If you bought a 4K TV with a true 120Hz refresh rate, like for use with a PlayStation 5 or Xbox Series X, you should move up to an Ultra High Speed HDMI cable.

The Benefits of Free Weights for your Training Routine When it comes to working out
Описание: The Benefits of Free Weights for your Training Routine When it comes to working out, there are so many tools, machines, and techniques. How do you know which one is best for you? The answer isn’t so simple since each one has their own unique advantages. However, fitness and health expert Emily Schromm shares some benefits of free weight training to help navigate the world of free weights vs machines. Benefits of Free Weights Decrease Imbalances- Using weight machines or barbells can lead to strength differences in each side of our body. When using these methods, it’s common for one side of the body to become more dominant and take on more of the work in an exercise. Free weight exercises allow us to load each side of our body equally, which prevents muscle strength imbalances. Often times, we don’t realize that strength imbalances are there until we incorporate free weights. Strength Gains- Utilizing free weights to decrease imbalances will allow our weaker side to get stronger. Beyond that, free weight exercises require more control and balance. This means that more muscles are recruited to stabilize the weight which ultimately leads to more gains. Injury Prevention- Free weight exercises are great at strengthening the body’s stabilizing muscles. These muscles play an important role in keeping your joints in place as well as supporting your body, so keeping them strong is a great way to prevent injuries. Promotes Functional Fitness- The term functional fitness refers to exercises that have applications for everyday life activities. For example, doing exercises where you lift weights off the ground trains your body for similar movements. Performing activities like picking up a laundry basket or child becomes easier because your body is conditioned for it. Free weight exercises tend to have more real-life applications. Outside of the gym, most of the weight we lift is “free”, meaning our body needs to have strong stabilizing muscles to support the activity. Free Weight Exercises Free weights are ideal for working slow, controlled movements. Emily Schromm suggests incorporating exercises like dumbbell snatches, Turkish get ups, and windmills to get some of the benefits of free weights. Don’t stop there, free weights can be used to target any muscle group you want to work. Free Weights vs Machines Both free weight exercises and machines have their pros and cons. Weight machines can be useful for beginners for teaching proper form. Plus, weight machines can allow for higher weight volumes to be achieved. With any training routine, it’s about balance. You don’t need to go all in with free weights to take advantage of the benefits, just try incorporating some free weight training to your routine! 5 Benefits of Dumbbell Training Most health clubs and gyms offer rows of cardio equipment, aisles of weight-training machines, stacks of free weights and specific stretch areas to help members pursue their individual goals. When it comes to fitness equipment, there is no one “best” piece of equipment. Different types of equipment are purposefully designed to achieve specific fitness outcomes. For those with goals related to strength training, there are countless options for increasing lean muscle or adding strength. Choices include the traditional weight machines, barbells or dumbbells, as well as a wide variety of specialized equipment such as kettlebells, medicine balls, sandbags and even oversized tires. Some forms of resistance training equipment, such as barbells, are more effective for developing max strength, while weight-training machines can help increase muscle definition and lighter forms of resistance such as medicine balls and kettlebells can be useful for improving movement-specific power output. Dumbbells are often used for joint-isolation exercises such as biceps curls, chest flyes or shoulder raises. Using dumbbells for full-body, multiplanar movements, however, can provide a variety of different strength outcomes. It also offers many benefits for cardiorespiratory fitness and flexibility. To help you select the best equipment for your needs, here are five benefits of dumbbells: Dumbbells can provide the two types of overload that lead to muscle growth: mechanic and metabolic. Mechanic overload is the result of damaged caused by muscle contractions, which stimulates the repair process and leads to an increase in muscle size. Metabolic overload occurs when a muscle is worked to fatigue, which leads to the adaptation of muscle cells being able to store more glycogen which can cause muscles to increase in size. Heavy dumbbells can generate mechanical overload, while moderate-weight dumbbells combined with high reps (to fatigue) can produce metabolic overload. Dumbbell exercises can create both inter- and intramuscular coordination, leading to greater levels of muscle activation. Intermuscular coordination is the ability of a number of different muscles to work together to produce and stabilize joint motion. Intramuscular coordination is the amount of muscle motor units and their attached muscle fibers that are activated within a specific muscle. Using lighter dumbbells for compound, multijoint or multiplanar movement patterns improves coordination between different body segments. Using heavier dumbbells can increase the number of muscle fibers activated within a specific muscle. Dumbbells can benefit both the contractile element and elastic component of muscle tissue. The contractile element is the specific actin-myosin muscle proteins responsible for sliding across one another to create concentric shortening actions or control eccentric lengthening. The elastic component is the fascia and connective tissue that attaches each individual muscle fiber and groups of fibers to one another. The elastic component stores mechanic energy as it is lengthened, which is then released during a rapid muscle-shortening action. Traditional exercises with heavy dumbbells can increase the force production capacity of the contractile element, while multiplanar movement patterns with light dumbbells can enhance the resiliency and strength of the elastic component. Dumbbells can be used for a variety of exercises. Machines allow one motion in one specific movement pattern to place load on one muscle or muscle group. Due to their length, standard barbells are best used for compound movements in one specific plane of motion. Due to their size and the fact they can be held in each hand, dumbbells can be used to create a variety of different movement patterns to develop task- or movement-specific strength. Dumbbells allow the user to focus on one arm or leg at a time, which is one way to initiate strength gains by using a heavy overload. A single dumbbell can be used for exercises such as a one-arm overhead press or a split-leg goblet squat to create overload in one limb at a time. Weight plates make a great replacement for dumbbells and kettlebells, but using one also comes with a unique benefit: It improves grip strength because of the way you have to hold the plate (on the edges, with all fingers actively engaged) and core stability because of its positioning (typically in front of your chest). Plus, they can double as raised platforms for push-ups. Case in muscle-building point: the total-body routine below, designed by says Eric Quarshie, a Tier 3 trainer at Equinox Yorkville in Toronto, Canada. “Together, these exercises work all of the body’s basic movement patterns and major muscle groups while also honing in on the stabilizer muscles, especially those of the core that also allow for rotation,” he says. Rotational power is critical to sports performance—whether you’re running, lifting, climbing, or performing martial arts. The workout contains two four-move circuits. Perform 12 to 15 reps (per side, when applicable) of the first four exercises back to back. Rest for 30 seconds to 1 minute, then repeat for a total of 4 rounds. Follow the same format with the last four exercises. Do this workout at least three times per week for optimal results. Or, whenever the gym’s packed and you don’t have time to wait for the dumbbells and squat rack to free up. There are a number of terrible reasons to love bumper plates. They are rubbery, bouncy and don’t smell like rust. They take up tons of room on the bar, creating the illusion of lifting lots of weight. You can even slam them down from overhead if you enjoy using a bent barbell. Most importantly, you mysteriously set PRs every time you deadlift with them after training with steel plates. I hate to be the one to burst your bumper plate bubble, but deadlifting with bumpers is significantly easier when compared to iron plates. This doesn’t mean that your coveted PR no longer stands. It just means that you have introduced another variable to consider when measuring your strength. When you PR your deadlift using bumper plates, you obviously still lifted the weight. But were the conditions the same as the last time you hit a personal best? Did you really get stronger? Or did your equipment simply give you additional mechanical advantage? The real answer is probably some combination of the above. We can solve the mysterious case of the bumper plate PR with a little science and engineering.

Secret Of Marble Formation in Mother Earth
Описание: Secret Of Marble Formation in Mother Earth Marble is one of the greatest gifts of nature. Inimitably precious and irresistibly intriguing, marble is perceived as the most precious material that fascinates with its distinctive characteristics, colors, patterns, texture and finesse. The formation of marble involves a series of complex strides and processes. It begins at the deepest quarters and crust of our planet Earth and ends with the execution of remarkable interior designs and décor concepts. From extraction to installation, turning raw marble into a masterpiece requires rigorous contemplation. Admired and revered for its brilliant aesthetics and supreme grandeur, the marble formation begins with the phenomena within the crust entailing the fusion of various elements, energies and forces. To enlighten you about the complexities, intricacies and practices from creation to finalization of marble into a stunning masterpiece, we bring to you a short sequential guide illustrating the entire process. How Marble is Formed? The formation occurs due to a reaction when limestone is subjected to intensive heat and pressure. The composition of marble consists of various minerals such as clay minerals, quartz, pyrite, micas, iron oxides and graphite, etc. but primarily the calcite. The phenomena of metamorphism involves recrystallization of calcite in the limestone leading to formation of rock that is a result of collective amalgamation of calcite crystals. Extraction of Marble Extraction process of marble is executed at the quarries in the rocky mountains. To perform efficient sourcing and carriage operations, professionals with tremendous expertise and highly sophisticated equipment are deployed. The pre-extraction arrangements also includes preparation for safety and preservation. Extraction of Marble Extraction process of marble is executed at the quarries in the rocky mountains. To perform efficient sourcing and carriage operations, professionals with tremendous expertise and highly sophisticated equipment are deployed. The pre-extraction arrangements also includes preparation for safety and preservation. Pre-dispatch Procedures The vehicles with huge loading capacity are used for transportation of the material in large quantities to specific facilities depending upon the requirement for treatment or transformation into sheets. The marble turned into slabs or sheets are further examined thoroughly for initiation of other imperative procedures like finishing, polishing and plastering for finalization of the same into an end deliverable. After detailed scrutiny and assessment, China marble is ready to be supplied to the market for selling. WHITE MARBLE White Marble represents purity and peace. Many architects use white marble, either for cladding or flooring, in order to bring spaciousness and luminosity to a room. Another of the qualities of white is that it is timeless and therefore, always in fashion. When it comes to matching, that is going to be easy. It works well with neutral tones (creams, blacks or greys), while combining it with other more eye-catching colours, such as red or green, makes it possible to soften ambiences. The shades of White Marble are innumerable. We can find whites with streaks, very clean whites or more greyish. It is nature that provides its exclusive touch to each one of them. Grey Marble Attributions to Architecture and Design Grey marble attributions to architecture and design are to be discussed here. Grey Marble Represents Depth Pietra Grey Marble due to its ash tone creates depth. As grey comes in shades from near white all the way to dark charcoal, it’s easy to use it to create light and shadows. Subtle variation of the same color can add character and take a plain room to a multi-dimensional one, creating recesses and reliefs where there are none. Grey Marble Represents Elegance Pietra Grey Marble has an elegant toner. Grey can make almost any color smokier when blended in. Some examples are grey-blue, grey-green, or even dusky pinks and browns, such as clay-beige. In addition, it also marbles nicely with other neutrals to create complexity and tone down the harshness of a single color on its own. Grey Marble Represents Formality Grey is formal. We’ve mentioned that Pietra Grey is sophisticated and elegant. It is also a traditionally formal, conservative color. This may be why we often see grey as a popular choice for uniforms as well as for suits and wedding tuxedos. These suits represent balance, steadfastness, and dependability. While grey can also be whimsical when offset with vivid colors, grey’s cool elegance when coupled with silver and wood is the perfect marriage for your formal rooms. Why beige marble is preferred in home flooring ? We have all seen movies that exhibit luxury-defining grandeur in the interiors. There have been specific moments when the want to own a home that whispers our taste of opulence. Be it Baroque, Victorian, Neoclassical or the modern alternative, Minimalist styled interiors, when it comes to show-casing life king size, the shades and hues of beige take the front row. The colour beige brings out the perfect elegance that you desire of your interior and enhances interiors in ways other colours can only gawk in awe at. The greatest architects and interior designers of our time have long since known the class that beige holds in itself and the rich excellence it generates when used intelligently. You can openly declare your love for beige as does the royal chateau of Palace of Versailles in France or you can use the subtle beige accents like the Belgium suite of Buckingham Palace in United Kingdom. Wherever your interior inspiration spring from, be it movies, or a Broadway adaptation of a play, or your ambitious imagination while reading a book, or from the glazing leaflets of a designing magazine, beige marble in the interiors is all your ideas and prayers answered. When it comes to floorings, beige marble has proven itself to be the archetype of excellence and perfection. Interiors So Lit! Beige coloured floorings look demure. They reflect the light that falls on their gleaming surface with soft scattering-like effect that makes it amazingly easy on the eyes and essentially visually appealing. The aesthetics are an important part of interiors. They make your soul sing with adoration when you gaze upon a beautifully decorated home. But, Oh! The Contrast! Imagine magenta against beige, or textures of mahogany… envision pink flowers and violet drapes… visualise velvet green upholstered ottoman in front of a rocking chair in your favourite reading nook… The point behind this imaginative mental exercise is that beige provides the best contrast there is. The regal front that it fosters is just a natural property of beige. Your furniture look outstanding, decorative objects and showpieces attain the right amount focus, and soft lights create a peaceful overall ambience. You’ve Got It, You Flaunt It! For people who love the modern styles of interior decoration, the clean and crisp styles with no over dose of gilded golden glitter scattered around in distracting fashion, like the contemporary and minimalist, beige floorings are perfect too. Flaunt the beauty of your home, you don’t need a rug for covering up floors that sparkle with magnificence. Interiors So Lit! Beige coloured floorings look demure.

Granite stone is often used in buildings, bridges, paving, monuments, countertops, tile floors, stair treads and many other design elements.The word granite has been derived from the Latin word ‘granum’ meaning grain. Granite is an intrusive, igneous rock with a granular and phaneritic texture, occupying 70-80% of the Earth’s crust. It is plutonic in origin, implying that it was formed deep underground. This rock is primarily composed of interlocking crystals of alkali feldspar (65% by volume), quartz (20% by volume), mica, amphiboles and other minerals. Depending on the mineral composition, the colour of granite can be red, pink, grey or white with dark mineral grains visible to the unaided eye. Granite is a hard and tough rock with an average density between 2.65 and 2.75 g/cm. It is found in abundance in all continents as part of the continental crust. This rock is found either in small, stock like masses spread over an area less than 100 km2 or as batholiths which are part of orogenic mountain ranges. Granite usually forms the base underground rock with other continental and sedimentary rocks resting over it. Granite also occurs in lacoliths, dikes and sills. Other rock variations, similar in composition to granite, are alpites and pegmatites. Alpites with finer grain size than granite, occur at the margins of granitic intrusions. Pegmatites with coarser grains than granite often share locations with granite deposits. Formation There are several controversial theories regarding the origin of granite. The most widely propagated ones are the magmatic theory and the hypermetamorphic theory. According to the magmatic theory, plutonic rocks like granite, which are often found associated with mountain ranges, originated from magma. It is believed that during the formation of mountains, when one continental edge subdues another one below it, the pressure and frictional forces generated by this phenomenon is sufficient to melt the rocks underneath the subdued continental edge. This melted rock or magma seeps up in the form of large globules or plutons. It takes an extremely long time for the plutons to arrive at the surface of the earth and to be converted into a surface rock, the pluton must be eroded by the weathering forces acting on the ground. This could be one of the processes by which granite formation takes place. The hypermetamorphic theory, however, disregards the magmatic theory and instead propagates that granite is the result of melting and re-crystallization of sedimentary rock instead of magma. However, as of yet, the precise method of granite formation, is still under research till a conclusive proof of formation of this rock is attained.

Blister Machine Features Vacuum System for Reject/Transfer In the compact TF1pro
Описание: Blister Machine Features Vacuum System for Reject/Transfer In the compact TF1pro blister machine, a vacuum arm lifts ‘good’ blisters, precisely lowering them to the transfer actuator. Another key safeguard: an upper seal plate that retracts when web motion stops to prevent unnecessary heat exposure. Pharmaworks, part of ProMach Pharma Solutions, introduces the TF1pro, the next generation system in its TF1 family of compact ba-600 linear pallet automatic blister card packing machine at PACK EXPO Connects. The system is particularly suited to small to moderate batch sizes and clinical trials for pharmaceutical and biotech manufacturers and contract packers that frequently changeover. The fully servo-driven blister machine runs up to 100 indexes (200 blisters) per minute. While smaller systems don’t always have the bells and whistles of high throughput machines, Pharmaworks added many features to maximize product safety and ease of cleaning, while also achieving fast changeovers, accuracy, and versatility. Ben Brower, director of sales and marketing at Pharmaworks, said, “Two years ago, a large pharmaceutical company approached us and asked us to develop a compact blister machine with the most advanced cGMP features. With their design input, we developed the TF1pro, the only ba-350 turntable automatic blister card packing machine on the market that offers this high level of product safety and sanitation in a small footprint.” Applications The system accommodates tablets, capsules, softgels, vials, syringes, liquids, and more. The intermittent-motion TF1pro supports both thermoforming and cold forming applications and runs a wide range of base materials with a standard roll diameter of 500 millimeters, providing twice the production capacity of the ba-600h automatic hf double blister packing machine. The usable forming area is 120 by 165 mm with a depth of 25 mm. Optional product vision inspection and print vision inspection are available, as well as full serialization if needed. Processes and parameters, including temperature, pressure, and the timing of each step are PLC-controlled and programmed as a unique recipe in the TF1pro’s large HMI. The TF1pro offers either Rockwell Automation or Beckoff control systems. Operation As the base roll unwinds, an optional feature monitors roll diameter and alerts the operator when it's time to add fresh material at the splicing station. Power-driven rollers form a loop in the material, while a sensor ensures that the material loop is in the correct area. This touchless feature helps prevent excess drag on the material, meaning less stretch, saving on costs by allowing the use of small width base rolls. Next, a splice detector that notifies the operator when there is a splice in the web, allowing the machine to track the splices and automatically reject that section of material. The company reports that automated adjustment of heating plates, forming tools, and other change parts translates into a 30% reduction in changeover time versus other TF series machines. It features ergonomic components that slide in and lock, including the guide track on the feeding station. The heat area automatically retracts when not in use for operator safety and convenience during changeovers and maintenance. Sloped surfaces throughout the system eliminate the chance of cross-contamination from trapped product or debris, which also speeds changeover by simplifying machine cleaning. At the heating station, upper and lower plates apply contact heating to the base material. The heating station opens fully during machine stop to remove heat from the material. There are optional burnout detectors to determine that all heating elements are working correctly—these will stop the machine if an issue is detected. The warmed material is then indexed to the form station where upper and lower tools create blisters of predetermined shape, size and depth. These are change parts that permit toolless changeover, depending on the blister dimensions needed. Driven by a servo motor, the lower tool moves upward during the forming process and this travel can be changed and stored on the HMI to allow the most efficient motion for a given blister size. The blister cavity can be formed with air only or air-plus plug assist (for cavities up to 25 mm deep). The TF1pro is available with a wide variety of options, including selective forming that enables specific pockets to be turned on and off within the same tool. Pinhole detection for the lid material and/or the base material is available for cold forming. Additional options include a lid material splice table, a splitter, servo plug assisted cold forming and both helium and nitrogen gas flushing. Feeder options Finished blister cavities are indexed to the feed area, a separate module on the TF1pro that can be tailored to almost any length needed up to twenty-five hundred millimeters. Open access from the front and rear in combination with feed area length allows automatic feed systems to nimbly dock and undock as needed or allow operators to manually fill blister cavities. Pharmaworks offers several feed systems for its blister packaging machines. The machine on show used the FA1 feeder (also common are the FF1 and FT320) with servo-driven technology to pick and place product into blister cavities. This next generation FA1 feeder is enhanced for more reliable pick motion and features that speed cleanup and enable toolless installation. At the feeding stage, product is conveyed across a vibratory sift tray, where dust and debris are removed product is aligned in the feed track. The product populates each groove in the slanted track, enabling gravity to pull the product down the track. The end point of each groove is pre-engineered to match the blister cavity orientation on the web. (When feeding is done manually, operators can work from either side of the machine.) Before the blisters arrive at the seal station, the TF1pro’s advanced vision system inspects the product shape and color, and checks for broken or missing product. The vision system logs this information on good and bad blisters into the blister tracking register (BTR). The position of bad blisters on the web is identified, and these products will be rejected later. Lidding may be preprinted or printed online with the required lot and date codes. Several third party printers are compatible with the system while a Scanware print vision system checks and logs print quality. To ensure consistent and accurate seal integrity a load cell provides real time information on seal pressure. A secondary high-speed sensing system will detect any foreign object between upper and lower seal plates. If an object is detected, the sealing cycle will instantly stop and reverse plate travel. Another safeguard on the TF1pro is a retracting seal plate—if web motion stops, the upper seal plate retracts to the rear so that the web won't be exposed to unnecessary heat. Vacuum arm The blisters are then perforated and die cut by the inverted die punch. The reject/transfer station uses a vacuum arm to lift the “good” blisters onto the outfeed conveyor while “bad” blisters simply drop down into the reject bin, which ensures consistent and accurate ejection. Positioning the die cutter in this way also provides space at the end of the web for direct coupling of a cartoning machine. Blisters can be manually packed as well. PACK EXPO Connects continues to bring the industry together in record numbers this week with over 17,000 attendees as of Wednesday. Even after the PACK EXPO Show closes, informative Jumpstart sessions, Innovation Stage presentations, and exhibitor live demos will be available on-demand until March 2021. Be sure to register today so you don't miss out! Blister packaging, or blister packs, are pre-formed packaging materials composed of a thermoformed plastic cavity and a pliable lid. In this type of packaging, the product is placed in deep-drawn pockets or cavities resembling a blister. A backing material or lidding mates to the flat area of the plastic cavity enclosing the product inside. Bonding the two structures is a heat-seal coating adhesive. Blister packaging has various types depending on the application. The most popular use of blister packs is packaging pharmaceutical products such as pills, tablets, capsules, and lozenges. Because of its low cost, cheap raw materials, and high operating speed, they are also used for packaging consumer goods such as foods, electronics, toys, and tools. Enumerated below are the benefits of using blister packaging. “The conversations between Rohrer and Starview have been going on for quite a while,” said Sarah Carson, Head of Marketing at Rohrer. “But in the past year or two the pressure on consumer packaged goods companies to deliver on ambitious sustainable packaging goals by 2025 was increasing considerably, to the point that customer demand started to really ramp up. That included one significant customer who was so serious about the idea that it gave us a powerful business reason to invest in the R&D that it was going to take. Fortunately, we had already established a great partnership with Starview from the machinery side.” “We had both intended to actually launch this last year at PACK EXPO in Chicago,” said Robert van Gilse, Director of Sales and Marketing at Starview. As we all know, COVID-19 put the kibosh on that plan. But then when customer interest in the concept gre On the machinery side, a key goal throughout the development process was to come up with tooling that would make it possible for existing customers already running automated Starview bp-260a/e automatic platen alu-pvc alu-alu blister packing machine to get in on the all-paper blister option by simply adding an auxiliary feeder to any one of Starview’s FAB (Fully Automated Blister) Series of machines. With this tooling in place, a flat paper blister is picked from a magazine feed and, thanks to precision scoring done by Rohrer, is erected and made ready to receive whatever product the customer happens to be packaging. Then it’s just a matter of applying the blister card and heat sealing card to blister. As for the paperboard components that come from Rohrer, at the PACK EXPO booth demo the blister was a 14-point SBS and the blister card was a 20-point SBS. The virgin board is FSC-certified, notes Carson. She also says that Rohrer, a member of the Sustainable Packaging Coalition, worked with that organization to make it possible for customers to easily get permission to use the SPC’s How2Recycle logo on their blister packages. Printing, meanwhile, is done on an offset press, and both blister and card get an aqueous heat-seal coating. If customers so choose, a window can be die cut into the blister card to provide product visibility. Keep in mind that customers using this all paper blister are producers of products like kitchen gadgets or tooth brushes or pens as opposed to pharmaceutical or healthcare products where such a window would of course be out of the question. When asked what the All-Paper Blister will cost compared to comparable alternatives, both Carson and van Gilse said there are so many supply chain variables percolating right now that it’s difficult to say.

Best tufting machines and what you need to know An improved
Описание: Best tufting machines and what you need to know An improved carpet tufting machine with a precision drive system for laterally shifting the reciprocating needle bars of the tufting machine across a tufting zone in which tufts of yarn are made in a backing material advanced through the machine beneath the needle bars is disclosed. The precision drive system includes the use of inverse roller screw actuators which may be adapted for driving the several moving components of the tufting machine, to include not only the shifting of the needle bars, but also to reciprocate the needle bars toward and away from the tufting zone, rock the loopers and or knives of the machine, and to laterally shift the backing material in which the tufts of yarn are made with respect to the needles as the backing material advances through the tufting machine. A plain cut or plain loop tufting machine with an improved pattern yarn feed and distribution device for use in tufting a graphic pattern into the face of a tufted article. An improved pattern yarn feed drive is provided with at least two separate yarn drive control sections which together provide an increased number of controls such that any one control is adapted to drive a predetermined number of tufting yarns selectively passed thereabout for minimizing the length between any one of the tufting yarns and its respective tufting needle. An improved tube bank configuration is used with the pattern yarn drive assembly, and comprises at least two tube bank sections, each of which is also constructed and arranged to minimize the length of the yarns passed therethrough from a respective one of the yarn drive controls to a respective one of the tufting needles. This improved construction minimizes the problems of yarn elasticity and yarn lag when feeding the yarns to the needles of the tufting machine, thus greatly reducing the likelihood of a loss of pattern definition occurring in the graphic pattern being tufted in the face of the tufted article on the tufting machine. Rug tufting is a unique art in that you can create enormous works with relatively few materials. Once you’ve invested in a good tufting gun, you’ve got nearly everything you need to start tufting! The problem is, choosing the right tufting gun is difficult. Amazon and other retailers are filled with cheap knock-off tufting guns that break down after your first few rugs. To help you choose the right tufting gun for you, I put together this comprehensive buyer’s guide. First we’ll cover a few key details you need to know, then we’ll have a look at the best tufting guns, where to buy, and more. If you’re just looking for a quick recommendation, check out any of the models listed below. They won’t do you wrong! A tufting gun is a handheld FRS tufting machine used to make rugs. It’s much faster than manual methods like latch hook or punch needle, but a step down from industrial tufting machines for carpet. Tufting guns have a lot of advantages over other rug making or weaving techniques. As mentioned above, they’re very fast. A medium-sized rug can be knocked out in a few hours. They’re also relatively affordable. A few hundreds dollars will get you a solid machine, and the only supplies you need are yarn, backing material, and creativity. Rug tufting has been around for decades, but it’s come back into style recently thanks to social media platforms like TikTok. And I’m all for it! How does it work? Tufting guns work very much like a sewing machine. It has a “foot” that rests against the backing material, then a large needle pushes yarn through the material, leaving some on the other side. Depending on the type of tufting gun you have (or the settings), it will either leave a loop (loop pile) or a strand (cut pile) on the other side. More on that in the section below. One very important thing to keep in mind is that you can run more than one thread of yarn through the tufting gun at a time. Use creative combinations to make interesting patterns, or just save time by pushing through more threads at once! Loop pile vs cut pile tufting guns The biggest decision you need to make before buying a tufting gun is whether or not you want a loop pile or cut pile model. There are some models that can do both (learn more about that below), but they tend to be more expensive and fairly difficult to adjust back and forth. For beginners though, you should absolutely stick to a simple model. So how do you know which one to choose? Well, there isn’t really a right answer here. Both loop pile and cut pile tufting guns are great fun, and both can be used to create incredible pieces. Which one you choose will largely be personal preference. For me personally, I’d probably lean toward cut pile because I like the feel of the finished rug, but again, that’s just personal preference. Get inspired with the latest Tiny Workshops tours and interviews! Best tufting guns With all that background info out of the way, we can finally get to the main show: which tufting guns to buy and where to buy them! You’ll find a lot of junk models (especially on Amazon), but I’ve selected four of the best tufting guns that are reliable and easy to use for both beginners and experts alike. Note that all of the shops linked below sell both the tufting gun separately or a full kit with other tufting supplies. Tuft the World also sells an excellent starter kit, and you can save 15% with the code TINY at checkout! For beginner tufters, the AK-I is the best tufting gun there is. It’s limited to cut pile tufting, but it remains a popular option because of just how easy it is to use. This thing is easy to set up and hard to break, both of which are extremely common problems when tufting. Plus, it weighs just 3lbs (1.4kg), whereas other models can weigh five times that. It’s great for long tufting sessions. The main problem with this model is availability. Most shops take pre-orders, and it can take 3+ months to ship. That’s a long time to wait for a new hobby. Thankfully, the shop listed below seems to maintain stock. It’s based in New Zealand, but they use express air delivery so you can expect your machine in less than two weeks, no matter where to live. To make matters better, they offer a variety tufting gun kits, as well. You can get your AK-I cut pile tufting gun with a frame, primary tufting fabric, yarn, or even a second loop-pile tufting machine (the AK-II, listed below). Another place to buy the AK-I tufting gun is a specialty shop called Tuft the World. They have a variety of tufting supplies on offer, and you can save 15% on your purchase at checkout with the code TINY. Next up is another single needle table tufting machine from the same manufacturer, but this time it’s aimed at loop-pile tufting. All of the benefits of the model above still apply here: it’s lightweight, durable, and easy to set up. The only difference between the two is the type of rugs they can create. However, it also suffers from the same big downside. It can be very difficult to get your hands on, and most shops deliver months after purchase. Again though, the same New Zealand-based shop mentioned above offers great pricing and shipping times of just over a week. You may be able to find one a bit cheaper, but you won’t find one that’s more convenient! The same kits and bundles are available here, too. If it’s sold out there, you can also buy this model from Tuft the World. Availability is a bit more limited, but you can still save 15% with the code TINY at checkout. If you absolutely must have a tufting gun that’s capable of both cut pile and loop pile tufting, the KRD-I is one of the best around. Featuring an improved design over its predecessor the KD-II, this is an industrial grade artificial turf tufting machine. It supports both 110V and 220V power, with a handy speed control knob to slow it all down when you need to. However, this isn’t a tufting machine for beginners. Swapping between modes requires some expertise, so it’s best left for intermediate or advanced tufters who know their way around a basic machine. Like this other models on the list, you can buy this one on Etsy at the link below, or at Tuft the World when it’s in stock. Remember to use the code TINY to save 15%! Ok, so you’re a relative beginner but you still insist on getting a tufting gun capable of both cut and loop pile tufting? Well, the AK-III is the model for you. It has many of the same great design elements of the AK-I and AK-II above, but comes with extra parts and features that make it a combo tufting gun. Although this model is relatively easy to use, there is one big caveat. This is an industrial-grade pneumatic tufting gun, so to use it you’ll need some kind of compressed air system. That alone will likely add to your setup costs enormously, and the tufting gun itself is one of the priciest on the market. Still, it can be a great investment for the truly dedicated tufter with a large budget. Buy it on Etsy at the link below, or from Tuft the World with the discount code TINY. By last pick for the best tufting guns is the ZQ-II. It’s the older version of the KRD-I listed above, but it’s still a very capable machine. Again, it’s capable of both cut pile and loop pile work, but it’s considerably heavier and more finicky to set up than the other models on the list. That said, if you know someone who can show you the ropes, you’ll be tufting away in no time. You also don’t need to invest in an air compression system, which is great for small or residential workspaces. Learn more at the link below, but be aware that supplies are limited to it may be sold out soon! It’s a lot less violent than it sounds. Tufting is essentially a type of textile craft — much like embroidery or knitting — that’s traditionally used for making rugs. Hand-tufting has its roots in Persia (or modern-day Iran), where the world’s oldest carpet was found. In ancient Persia, the art of tufting varied between villages, which each developed their own weaving patterns and used different yarn colours and knots for their carpet creations. Centuries later, the craft would arrive to the US by early settlers who wanted to make warm clothing. The world’s first mechanised tufting machine would be developed in Georgia in the 1930s, making chenille rugs and wall-to-wall carpeting very popular. Hand-tufting would see a revival in the ’50s, before falling into a decline with the prominence of latch-hooking, another way to make rugs, in the’ 70s. Tufting seemed doomed to remain forgotten in the 21st century, but thanks to artsy (and bored) users on TikTok and Instagram, the craft has made a comeback — at least mechanically. Now everyone wants to pick up a tufting gun and punch yarn through a cloth canvas to create a rug resembling their favourite Marvel / Disney / Studio Ghibli character. It has even stirred a crafting frenzy among couples — what could be more romantic than a session at a rug-making workshop? Whether you intend to DIY at home or attend that aforementioned workshop for your next date, read on for our guide to tufting in Singapore and discover all you need to know. To control the yarn vibration in a reasonable range and to improve the quality of tufted carpet, it is very important to understand the vibration characteristics of yarn correctly. The transverse vibration equation of yarn is established using Newton’s second law in different paths, and then the yarn vibration characteristic curves in different regions are obtained. Firstly, the yarn path is divided and the optimal constitutive model of tufted carpet yarn is determined. Secondly, the transverse vibration is built by analyzing the force of yarn means. Then, the partial differential equation of yarn vibration is simplified as an ordinary differential equation by the Galerkin truncation method. The equation is solved numerically by using the Runge–Kutta method, obtaining the yarn amplitude in different regions. The vibration characteristics of the yarns after the jacquard parts are emphatically analyzed, and the effects of the speed, tension and damping coefficient on the vibration characteristics of yarns are also discussed. Finally, the results are verified by experiments.

Описание: Why One Should Go For Outdoor LED Screen Rental The rental led display screen is becoming popular day by day because of its features such as brightness, ambiance, and long-range visibility. Are you wondering to rent an LED screen for entertainment? If yes, then let me tell you, this article is dedicated to you. Today we are going to discuss the benefits of renting an LED screen. The overview of today’s article is listed below. Note it down away! Easy to set up Brightness They are reliable Let us discuss them in detail: Easy to set up: LED screens are not only easier to set up but also turn on fast. It is best for the businesses who want to give their visitors the best outdoor experience but with little effort. Brightness:Commercial LED display doesn’t suffer from a decrease in vibrancy. It attracts the attention of visitors due to its bright color. They are reliable: Regardless of the weather condition, a high-quality outdoor LED screen rental will be able to withstand tough weather conditions such as heavy rain and winds. They will even display crystal clear pictures and sound that your audience will enjoy. If both answers are definite, I recommend you read this article so that you know what you need to consider for the indoor rental led display for events. First of all, it is to differentiate between outdoor or indoor LED screens and LED screens with LED feedback. LCD screens are like computer monitors, while LED screens for events are panels of light-emitting diodes that can form words, images and videos. An example is the panels that you can find on the stage of a concert or the information panels of the highways. But what quality can these screens offer? The quality of these electronic LED signs is perfectly valid for events, both indoors and outdoors. In the different activities and shows, the LED screens, which are generally large, work as video walls but with higher quality, brightness and brightness. Without a doubt, they will capture the attention of all the spectators. If you are thinking of preparing a fair or a congress, the indoor rental led display is a wise option, since you can reproduce all the content of your company, from videos to graphics animations and high-resolution videos. What screen should we choose? There are several aspects that we must take into account when choosing an appropriate screen or, otherwise, our event may not have all the success we expect. The first thing to determine is whether we need indoor or outdoor LED displays. The second thing we have to know is the distance between the screen and the viewers. The higher the distance, the greater the screen surface. A three-meter screen located in height is not the same as a smaller screen located one meter away from the public. The resolution of the screen, that is, the distance between the LEDs is different, and with this, the sharpness of the image varies. Another aspect that you must choose is the type of protection that the screen will have, in the case that it is an external event, so that it does not suffer damage and to guarantee, at the same time, the correct visibility by all the spectators. Besides, we cannot forget the complementary equipment, such as projectors and mandatory auxiliary equipment that are necessary to achieve optimum reproduction of the images. Usually, companies are specializing in the indoor rental led display, transport and mount them adapting to the needs of each client and scheduled event. Therefore, the only thing that the organizing company or the final customer should worry about knows what they want to communicate and project. Leaving in the hands of professionals the advice first and the execution later, you have to worry about focusing the content and thus guarantee the success of the event.
