Self-powered roller improves web control
Article Abstract:
Urenco and the University fo Sheffield has developed a lightweight roller that could soon be utilized in process lines in the printing, packaging and textile industries. The self-powered roller consists of carbon-fiber composite and could be directly run by a built-in electric motor. The new design reduces weight and achieves various operating speeds because it does not have a gearbox. The carbon-fiber composite material is produced by a mixture of resin and powdered magnetic material of neodymium, iron and boron. As much as 20% of magnetic material is present in the resulting composite, which would allow it to serve as a rotor in the brushless electric motor.

Pumped-up mixer improves hydrogenation
Article Abstract:
Lightnin Inc. of Rochester, NY, has developed the A340 impellers that is claimed to reduce number of batch times by up to 50%. A340 impellers removes the need for sparging since it allows hydrogen to be introduced through the reactor headspace according to mixing technology vice president Thomas Post. A340 impellers, which is designed to extend catalyst life in hydrogenation, are arranged in a series that creates an up-pumping liquid motion. Four companies have already been installed with these impellers.

A thickness meter simplifies refractory maintenance
Article Abstract:
Teledictor of Tipton, UK, and Sheffield Refractories of Worksop, UK, have developed an instrument for measuring the thickness of refractory linings in kilns and furnaces. Traditionally, kiln operators measure refractory thickness by inserting a mechanical probe into a hole. The instrument does away with hole drilling, which can damage the bricks, plus it is easy to use. The companies expect to have launch a commercial version of the instrument by the end of 1998.
