about a replacement for metals. Carbon-reinforced Xycomp thermoplastic
composites have 80 percent lower density than steel, 60 percent less than
titanium, and 40 percent less than aluminum. They have higher continuous
service temperature capabilities than most plastics and better toughness than
They are used as containment shells in magnetic-driven pumps
and mixers to form a closed system that seals off the fluid contact areas of
the pump/mixer. This seal-less design replaced the traditional style of
packings and complex mechanical seals, with their associated piping, valves,
cooling units and other equipment, and offers a reduction in maintenance.
Traditional shell materials such as Hastelloy or carbon-reinforced epoxy are
said to suffer from significant energy losses through eddy currents.
The reduction in eddy current using Xycomp shells means there
is no heat generation and a stable fluid temperature, boosting the safety level
in hydrocarbon applications where pumps are operating with media close to the
boiling point. Xycomp composites can be made from polyphenylene sulfide (PPS),
polyether imide (PEI),
poly(aryletheretherketone) (PEEK), or poly(ether ketone ketone) (PEKK). PEKK is
said to be the only polymer that can withstand continuous high temperatures of
around 260C - its melting point is 360C.
Xycomp components are molded through the proprietary Techna3
process, which produces complex tubular shapes with flanges, reinforcement ribs
and closed ends. www.gtweed.com
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.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
