Best-kept secret in the circuit breaker industry
When STELPRO, a Quebec-based manufacturer of integrated heating solutions for the HVAC industry, asked partners all along its supply chain to identify cost-saving opportunities, installing NOARK miniature circuit breakers in panels on all their equipment was one solution that provided long-term quality and savings (typically 30 to 50 percent in price). NOARK's five-year warranty was a huge added bonus.

Diesel gets way cleaner with new injector technology
An engine innovation first conceived and tested by Sandia National Lab has attracted the attention of big business because of its potential to eliminate between 50 to 100 percent of diesel soot emissions and maintain or improve engine performance. The idea for ducted fuel injection came from studying a simple Bunsen burner.

Superhydrophobic metal won't sink -- even when damaged
Inspired by diving bell spiders and rafts of fire ants, University of Rochester researchers have created a metallic structure that is so water repellent it refuses to sink -- no matter how often it is forced into water or how much it is damaged or punctured.

Trends in fastening technology: Smaller, lighter, easier to install
Fastening technologies and assembly techniques are evolving to meet continued demands for reliability, throughput, and ease of manufacturability. One trend sees designers involving parts manufacturers in early design phases to ensure design for manufacturability (DFM). Another sees the fasteners themselves becoming smaller, stronger, lighter, and easier to install by automated and robotic assembly systems. Traditional and robot-ready fastener machines are also evolving. By Michael Wolff and Ron Boggs, PennEngineering

Image - How to calculate plastic injection molding shrinkage
How to calculate plastic injection molding shrinkage
Do you know how to calculate the shrinkage of your part ahead of time? Plastic injection molding shrinkage is the contraction of a plastic molded part as it cools after injection. Most of the part shrinkage occurs in the mold while cooling, but a small amount of shrinkage occurs after ejection, as the part continues to cool (especially for Delrin or POM). After that, the part may continue to shrink very slightly for several hours or even days until the temperature and moisture contents stabilize.

Image - New ball screw for machine tools
New ball screw for machine tools
Featuring high-speed performance and load capacities that exceed existing full ball standards, THK's new Type BSM Ball Screw is ideal for use in machine tools. The Type BSM uses a newly developed circulation structure and a large lead to meet high-speed performance demands. The DN value is 170,000, contrasted with 130,000 in conventional products. The unique groove design and double groove structure improve load capacity. The Slim Nut Type BSM-B conserves space with a nut diameter up to 14 percent more compact than THK conventional ball screws. An extended overall length and increased number of loaded circuits ensure optimum rigidity.

New hygienic integrated electric actuators provide modular clean-in-place solutions
The Tolomatic IMA-S stainless-steel integrated servo actuator is designed for the most demanding food and beverage processing applications, eliminating harborage points and preventing bacterial growth. The 316 stainless-steel construction provides excellent corrosion resistance and withstands high pressure, high temperature, and caustic washdown. It meets clean-in-place requirements, allowing machine designers to achieve open machine designs and eliminate shrouding required to house standard actuators. This series offers forces up to 11.1 kN (2,500 lbf), stroke lengths up to 450 mm (18 in.), and options for planetary roller screws or ball screws. A proprietary lubrication feature helps extend service life.

A proportional isolation valve like no other
Clippard's new patented ceramic technology is the first to provide precise proportional control combined with isolation valve attributes to meet the needs of the most stringent analytical and industrial process control applications. This valve is ideal in critical applications for liquid and gas delivery, medical, analytical, and industrial automation requiring ultra-fine resolution and excellent repeatability. In addition, the unique design allows for custom flow profiles.

Image - Need help coupling two parallel shafts?
Need help coupling two parallel shafts?
Electromate offers a full family of power-on clutches from Inertia Dynamics for most applications. Power-on clutches are used to couple two parallel shafts. The armature hub assembly is mounted to the same shaft as the rotor assembly. The armature hub accommodates a pulley, gear, sprocket, etc., to transmit torque to the second shaft. The field assembly is mounted on the shaft and retained by a loose-fitting pin or bracket through the anti-rotation tab. Typical applications include: packaging machinery, medical equipment, conveyors, postal sorters/readers, document feeders, textile equipment, and copiers/printers.

Navy demonstrates laser power beaming
Attendees recently gathered at the Naval Surface Warfare Center to stand around in the dark and look at something they mostly couldn't see. It was a long-range, free-space laser system -- the first of its kind -- beaming 400 W of power across 325 m to specially designed photovoltaics.

New Spirawave® Wave Spring Series
Smalley's Nested Spirawave Wave Springs are now available as standards. These flat wire springs are coiled in parallel with multiple turns to produce high loads, and are ideal for applications requiring high forces in tight spaces. When replacing single-turn wave spring stacks with one nested spring, misalignment and uneven loading are eliminated, simplifying assembly. Standard or custom, Smalley will provide you the right part, in the right material, with No Tooling Charges™.

What warp speed actually looks like
Ever wondered what it would look like to see a spaceship traveling at warp speed across our solar system? Well you're in luck, because Dr. James O'Donoghue (a planetary scientist at the Japanese space agency JAXA and former NASA Fellow) has put together an animation to do just that. Get your Star Trek on as you follow a spacecraft in real time racing increasingly faster from the Sun to Pluto. From the far left, even moving at Warp 2 (10X speed of light) looks surprisingly slow -- but then again, it's a long way to go.
