Why Hot Foil Stamping Helps Packaging To Shine

Differentiation. It’s what every brand owner wants for their product, but in increasingly crowded markets, it is becoming harder and harder to achieve.

Brand owners know that packaging is the key differentiator on the shelf, and special finishing techniques – such hot foil stamping and thermal emb…[Leggi tutto]

Sandblasting

Air-abrasion (sandblasting) techniques have long been employed in restorative dentistry to enhance the mechanical adhesion between metals and adhesive resins. Sandblasting uses a high-speed stream of aluminum oxide particles propelled by compressed air to remove unfavorable oxides and contaminants, increase surface energy, bonding…[Leggi tutto]

Ball Valve – How They Work

A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life…[Leggi tutto]

Air Fryer

If you are a family of two, you can make easy meals with a small air fryer. While there are many different sizes of air fryers available in the market, for a family of two, an air fryer from 2 to 4 quarts will be ideal. As these air fryers are small in size, they do not take much space on the kitchen shelf, and they cook ample food for…[Leggi tutto]

How to choose the right retractable monitor?

A retractable LCD monitor for use in aircraft and the like is supplied with power from a power supply that is secured in a fixed off-monitor location on the monitor’s housing. The power supply also provides power for a motor assembly that controls a pivoting of the monitor between open and retracted…[Leggi tutto]

Automatic classification of granite tiles through colour and texture features

This paper is about the development of an expert system for automatic classification of granite tiles through computer vision. We discuss issues and possible solutions related to image acquisition, robustness against noise factors, extraction of visual features and…[Leggi tutto]

TURN YOUR KID’S ARTWORK INTO A SCRAPBOOK

The kids have only been in school for two months, but the papers and artwork are piling up. Normally I keep a select pieces of artwork and recycle the rest (after the kids are in bed). This year I’m taking a different approach. Armed with my Straight Talk Samsung Galaxy S6, I’m taking pictures of their…[Leggi tutto]

Calculation Inductance of Toroidal Inductor Wound by Rectangular Cross-Sectional Wire

In this article, we present two methods for calculation of the inductance of toroidal core power inductors wound by rectangular cross-sectional wire, considering that the current density is inversely proportional to the circular coil radius. The first method is…[Leggi tutto]

The integrated impact indicator revisited

We propose the I3* indicator as a non-parametric alternative to the journal impact factor (JIF) and h-index. We apply I3* to more than 10,000 journals. The results can be compared with other journal metrics. I3* is a promising variant within the general scheme of non-parametric I3 indicators introduced…[Leggi tutto]

Refrigerators

Now here’s a cool idea: a metal box that helps your food last longer! Have you ever stopped to think how a refrigerator keeps cool, calm, and collected even in the blistering heat of summer? Food goes bad because bacteria breed inside it. But bacteria grow less quickly at lower temperatures, so the cooler you can keep food, the…[Leggi tutto]

What is a Filter Press?

In some batch filtration processes, highly permeable suspensions dewater fast compared to the rest of the process. This work explores the impact of fast-filtering compressible materials on the throughput of fixed-chamber filter presses. The dewatering properties for a compressible yet highly permeable minerals processing…[Leggi tutto]

60 years of integrated circuits

An integrated circuit is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. Sometimes called a chip or microchip. The invention of the integrated circuit made technologies of the Information Age feasible. ICs are now used extensively in all walks of…[Leggi tutto]

Engineering Essentials: Fundamentals of Hydraulic Pumps

When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump…[Leggi tutto]

What is a 3-Phase Motor and How Does it Work?

Three-phase motors (also annotated numerically as 3-phase motors) are widely used in industry and have become the workhorse of many mechanical and electromechanical systems because of their relative simplicity, proven reliability, and long service life. Three-phase motors are one example of a type of…[Leggi tutto]

When you think of healthcare supplies, what comes to mind first? A stethoscope to hear a heartbeat. A syringe to give a needed shot. Ahhhhhh, the “open wide” tongue depressor!
But what about the Medical Tapes? It may not pop to mind first, but this versatile tool is incredibly important in the medical field. There are many varieties from whi…[Leggi tutto]

Be it carry bags or otherwise, with the escalating concerns for the rapidly deteriorating environment, it has become almost our responsibility to switch over to more eco friendly life styles. One way that we can do so is by using more eco friendly products. Given the environmental hazards that the huge use of plastic bags cause there is no doubt…[Leggi tutto]

What is Titanium Metal?

History

Titanium metal, with the symbol Ti, is the ninth most abundant element in the earth‘s crust. It does not occur in large deposits, yet small amounts of titanium are found in almost every rock. Titanium is a shiny grey metal with a low corrosion rate and high strength; it is used for various applications. It was d…[Leggi tutto]
