These high-performance heaters have diameter tolerances between -.001 and -.005 inches from specified nominal diameters, ensuring a good fit into the heater cavity. The heater's thermal expansion then makes for proper heater/surface contact for maximum heat transfer efficiency. They have a standard heater length tolerance of 1/16 inch, and a 5 percent wattage tolerance, but the company can meet specific lengths and tolerances, too. They are made for branders, mold heaters, packaging dispensers, gum, glue and wax pots, immersion heaters, ink processing, and food bag sealer applications.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
