Between 1980 and 2005, 281 combustible dust explosions killed 199 American workers and injured 718 more. A white paper prepared by Newson Gale Inc. provides the numbers and background data on the incidence of such accidents in terms of materials involved and those processes most vulnerable, plus guidelines for preventing static sparks, the most common ignition source of such incidents.
Detection & Shielding Of Noise In Stepper Motor Systems
Flex circuit design vs. PCB flex circuits still only account for about 15% of the overall printed circuit market. So it’s understandable that there are still questions about the design of a flex circuit vs. traditional printed circuits boards. Designers are warned that the design of a flex circuit is different, but it’s not that difficult and adding this knowledge to your experience toolbox is not as daunting a task as it may seem.
When faced with the challenge of reducing cost without sacrificing quality, damping greases can be useful tools in a design engineer’s bag of tricks.
Powder and bulk solids manufacturers have always had an inherent problem: once product is developed, it needs to be moved. Whether it is through a hopper or feeder system or merely transporting the material, the product needs to be moved. This sounds easy enough, but it can be very complex.
This White Paper offers a comparative look at a variety of motor technologies.

CAD-based inspection software helps CAD, Geometric Dimensioning and Tolerancing datums, and measuring devices work together to ensure design intent, and eliminate the need for 2D inspection drawings, while closing the loop on digital workflow. These are all important considerations when moving towards a Model-Based Definition (MBD) environment. CAD-Based inspection is a good practical first step toward the goal of a complete MBD environment.
Cable glands, sometimes also referred to as strain relief or cable connectors, are used in electrical equipment and panel construction to insure the integrity of the panel is maintained at the point of entry by the electrical cable. Several options are available, as this paper will discuss.
Large scale arrays based on Li-ion batteries can provide the high voltage, current, and capacity required by many emerging portable markets. However, there are numerous problems facing the designers of larger battery packs including the issues around cell imbalance. Here Micro Power outlines the techniques for achieving high voltage or capacity by building high cell count arrays.
Formulator Lab-Book Software is used by formulation chemists, food technologists and regulatory agents in the specialty chemicals (paint, adhesives, inks, cleaning materials, lubricants), food & beverage, nutrient supplements, cosmetics, fragrences and pharmaceuticals industries.
Protecting & Legally Defending the Authenticity and Ownership of Your Scientific Intellectual Property for the Long TermJanuary 27, 2011 9:55 am | by Surety
As a pharmaceutical or bio-sciences firm, your research, formulas and clinical findings are the "lifeblood" of your business. But if you aren’t protecting the integrity of your scientific research data in your lab management workflows, you risk losing patent ownership, revenue and consequently your business if you can't prove time of creation (“first-to-invent”) and authenticity. Learn how you can implement simple, cost-effective and automated controls into your existing lab management processes to protect your scientific intellectual property for the long term. These automated measures can also ease the costly and manual task scientists must follow to “sign and witness” volumes of research records, allowing scientists to focus on their research instead.
Applying industrial automation servos places additional constraints on the rules for power transmission design. Engineers must consider various options and risks when designing speed reducers, couplings, shaft configurations and other critical mechanical components. Mechanical load problems typically caused by backlash and/or compliance problems can be avoided with careful analysis.
Optical coupling fluids and gels serve as a “bridge” for light signals by carrying light between different media such as transparent plastic or glass light pipes or lenses. These materials, also known as Index Matching fluids and gels, are used to optimize light transmission (by matching the refractive index of the mating materials) while allowing pliable mechanical connections between rigid parts.
Industrial applications such as the factory floor are typically electrically noisy environments. Electrical noise, either radiated or conducted as electromagnetic interference (EMI), can seriously disrupt the proper operation of other equipment. Insulation protects a cable mechanically from scraps and abrasion and environmentally from moisture and spills, but insulation is transparent to electromagnetic energy and offers no protection. Shielding is needed to combat the effects of EMI.
