Abstract: A method and device for improving xerographic development of non-metallic photoreceptor imaging surfaces containing irregularities of 5 microns or larger by contacting and moving a smoothing and abrading means against the irregular surface in the presence of an interposed hydrodynamic hydrostatic fluid bearing.

Abstract: A lustrous top surface is imparted to artificial leather having a substrate, a flexible thermoplastic layer and a top coating essentially consisting of a thermoplastic resin by contacting the top coating with a mirror-like surface for a short period of time while applying heat to the intersurface therebetween at a temperature of at least about 10.degree. C. but not more than 40.degree. C. lower than the softening point of the resin in the top coating.

Abstract: A laminar board having a base of bonded wood particles carrying a decorat facing is produced by sequentially moving a carrier web through a loading zone and a press zone. The carrier web consists essentially of paper impregnated with a synthetic resin composition and having a permeability to water vapor of at least 1000 g/m.sup.2 /day. A layer of loose wood particles intimately mixed with a bonding agent is superimposed on the carrier web in the loading zone, and the resulting layered material is subjected in the press zone to a temperature and pressure sufficient to bond the loose particles to each other by the bonding agent in a dense structure and simultaneously to bond the particles to the carrier web by the bonding agent and/or the synthetic resin composition.

Abstract: A method is disclosed for coating a substrate or web with a plastic material. A liquid plastisol coating is applied to the web and the coated web is then passed between a put-on roll and a heat drum, which heats and cures the plastisol. The put-on roll is pressed against the heat drum to compress the coated web. The plastisol is partially cured to gelation while being compressed by the put-on roll, and the curing of the plastisol is completed during further travel of the web around the heat drum.

Abstract: A process is provided for the manufacturing of a hollow rotating body which process comprises mounting at least two wheels in a parallel fashion upon a shaft, placing a plurality of strips of glass fiber fabric along the outer circumference of the wheels, whereby an enveloping cylinder is formed, impregnating the strips with plastics or synthetic resins capable of subsequent setting, setting, applying helically layers of impregnated fiber strips tangentially to the cylinder mantle whereby the size of the walls increase, applying a reinforcing belt of wire or tape, applying a finishing coat of plastic or synthetic resin, whereby surface irregularities are smoothed, setting, and mechanically treating the surface to remove irregularities. An apparatus for accomplishing this process is disclosed.

Abstract: A process and apparatus for coating a band of a composition about a medial portion of an electrical component lead or terminal, where a continuous ribbon of a coating composition is extruded onto a medial portion of a plurality of spaced discrete leads or terminals extending transversely from a carrier strip. The continuous ribbon of coating composition is festooned between adjacent pins to coat paste on the sides of the leads or terminals. The leads or terminals and festoonery are transported over a surface of a wheel to apply the coating composition to the underside of each lead or terminal. A cut-off blade removes the excess composition from the underside of the terminal pins, as the pins leave the surface of the application wheel.

Abstract: Fabric is coated with a cellular blend of polyvinyl chloride resin and butadiene-acrylonitrile rubber, the said rubber component being vulcanized; the coating is buffed to expose the cells and thereby produce an artificial suede finish. The presence of the cured butadiene-acrylonitrile rubber in the composition eliminates the undesirable "glint" or shine that would otherwise be present, and gives a desirable flat finish. If an additional noncellular layer of the blend of polyvinyl chloride resin and butadiene-acrylonitrile rubber is interposed between the base fabric and the cellular surface layer, the abrasion resistance of the laminate is enhanced.

Abstract: Method for producing homogeneous surface alignment of liquid crystal materials by applying to the surfaces of transparent plates bounding a liquid crystal film a polymer which is subjected to a shear thinning technique to cause elongation and alignment of long chain polymers. In certain embodiments of the invention, the surfaces are coated with a polymer treated with a dichroic dye such that a polarizing film is formed adjacent the liquid crystal film. This eliminates the need for separate polarizers on opposite sides of a liquid crystal display.

Abstract: A contact fuser assembly for use in a electrostatic reproducing apparatus including an internally heated fuser roll structure comprising a rigid or non-deformable thermally conductive core capable of interacting with a release material applied thereto in such a manner as to form a thermally-stable interfacial coating intermediate the surface of the core and a release coating comprising portions of the release material. The interfacial coating strongly adheres to the core surface and prevents toner material from contacting the outer surface of the core. The combined coatings have a sub-micron thickness and therefore represent a minimal thermal barrier to the energy being conducted outwardly by the core.
