Fluctuations in rotating speed or in toque at the time of switching between series drive and parallel drive operations are prevented. When switching from series drive mode to parallel drive mode, the rotating speed Nb of a motor B is detected and a rotating speed command is transmitted to match the rotating speed Na of a motor A with the rotating speed Nb of the motor B. When the actual rotating s...

The present fiber reinforced cellular concrete is produced through a chemical reaction that does not require high heat or pressure ovens (autoclaves). Among its unique features, is the fact that different compression strengths can be obtained by varying the proportion of ingredients and resulting densities. The concrete utilizes a base of a pozzolanic product with aluminum powder, calcium carbonat...

A filter device and method of filtering components from a surgery plume. The filter device comprises an integral solution reservoir which intercepts an airstream passage and airstream and cooperates with the airstream to direct air and solution into pads to create a foam. The foam created by the pads and solution and additional elements of the filter react with one or more undesirable components o...

This invention relates, in general, to thermoplastic film and fiber structures and methods of making the same. More specifically, this invention relates to substantially water-free films and fibers comprising unmodified polyvinyl alcohol.

Spherically shaped polyvinyl alcohol (PVAL) polymer particles are prepared encapsulating a magnetic colloid that provides the particles with magnetic properties for use in binding biomolecules. The particles have a size of 1-10 mum that makes them particularly suitable for use in cell separation/sorting, cleaning biosubstances in suspension and diagnostic assays. The particles are prepared by disp...

Fibers as a reinforcing substrate are impregnated with the particles of polytetrafluoroethylene and pressed into a shape at the melting point of polytetrafluoroethylene. Alternatively, the reinforcing substrate sandwiched between polytetrafluoroethylene sheets is pressed into a shape at the melting point of polytetrafluoroethylene. In either case, the shaped article is then exposed to an ionizing ...

A method of forming a diffusion barrier on an article of a polymer blend of (i) a high surface energy polymer and (ii) a low surface energy polymer. Most commonly the low surface energy polymer is an organosilicon polymer, as a polysilane or a polysiloxane. The surface of the article is exposed to ozone and ultraviolet radiation to form a diffusion barrier.

A novel composition is disclosed comprising about 80 to about 99 weight percent based on the composition, of a linear ultra low density polyethylene (LULDPE) and about 1 to about 20 weight percent of a propylene polymer comprising 0 to about 40 weight percent olefin comonomer units having 2 to 10 carbon atoms and from about 60 to about 100 weight percent propylene, based on the propylene polymer, ...
