Abstract: Disclosed is an apparatus for simulating or practicing skating or gliding motion. The disclosed apparatus includes a platform and a low friction layer covering the upper surface of the platform. Also included are boards continuous with the low friction surface for providing a surface against which the skater may encounter increased resistance to movement. The end boards generally comprises two end boards mounted to the platform and inclined at an angle of between about 45.degree. and about 15.degree. with respect to the platform surface. A means is provided for dissipating the build up of static electricity from the low friction layer.

Abstract: This invention relates to composites of fluorocarbon polymers, preferably polytetrafluoroethylene, which contain less than about 23% by weight polyamide-imide resin. More particularly, this invention relates to extrudable polytetrafluoroethylene composites which exhibit improved abrasion and friction resistance and other improved properties over a wide range of temperature and load conditions, and which are particularly adaptable for use as liners in wire insulation and in push-pull cable assemblies.

Abstract: An apparatus and process for producing liquid droplets having a narrow size distribution. Thin liquid streams are forced under pressure through a plurality of orifices in an orifice plate, the largest of which orifices has a diameter not greater than about three times the diameter of the smallest of those orifices. Also the thin liquid streams are vibrated to cause the breakup of each stream into droplets having a narrow size distribution.

Abstract: Disclosed is a method for producing substantially unagglomerated submicron metal oxide particles having uniform size distribution. The process is readily adaptable to the production of multicomponent metal oxide particles.
