Abstract: A coated sheet for decorative or informational applications is formed of an oil absorbing substrate and an oil permeable decorative layer. The decorative layer is a porous oleophilic membrane formed from fused polymer particles. Skin oil and certain other liquids placed on the exposed surface of the decorative layer are absorbed into the sheet so that they do not appear on that surface and do not interfere with the optical effect of diffraction gratings or holograms thereon.

Abstract: A porous sheet material is inserted into a back side of a foam base material at a convex section and forces a mat-shaped fiber reinforcing material set in a mold toward a facing material during molding. Alternatively, an impregnated sheet material is inserted between the facing material and the fiber reinforcing material at the convex section so that a molding material for the foam base material is impregnated into the impregnated sheet material during molding. Further, a concave section is molded on the back side of the foam base material at the convex portion by a mold projecting section of the mold. That is, the fiber reinforcing material set in the mold is forced toward the facing material by the mold projecting section during molding.

Abstract: To produce a layer in a multi-layer circuit structure, a "green ceramic tape" (16) comprising a sheet of particles of ceramic, glass ceramic, or a glass/ceramic composite in an organic binder is applied to a ceramic substrate (12) on which conductive paths (14) have been deposited. A slurry of hollow microspheres (20) is then deposited onto the green ceramic tape (16), and pressure is applied to drive the spheres into the tape. A further tape layer (22) is then applied, and the resultant structure is fired.

Abstract: A decorative sheet is formed of an oil absorbing substrate and an oil permeable decorative layer. The decorative layer is a porous oleophilic membrane formed from fused polymer particles. Fingerprints and other skin oil placed on the exposed surface of the decorative layer are absorbed into the sheet so that they do not appear on that surface and do not interfere with the optical effect of diffraction gratings or holograms thereon.

Abstract: A multilayer structure is provided which has a core layer of a hygroscopic barrier material and inner and outer surface layers designed to facilitate the escape of moisture which becomes absorbed in the core layer during retort sterilization. The inner and outer surface layers include a polyolefin material which is either foamed or compounded with a filler in order to cause a substantial increase in the water vapor transmission rate of the polyolefin. Adhesive layers are present between the core layer and the inner and outer layers. Each of the inner and outer layers may include one or more individual film layers, depending on the requirements of the specific packaging application.

Abstract: A porous slide bearing (1) made of a porous sintered compact (5) is impregnated with an oil or a lubricant (6) containing a thickening agent at a concentration of less than 3 percent by weight and in the outer surface area thereof with a lubricant (7) containing a thickening agent at a concentration of 3 percent by weight or more. Such a bearing can prevent leakage of lubricant owing to fluctuations in temperature.A method for producing a porous slide bearing includes the steps of homogenizing a lubricant to make the crystals contained therein into fine particles and to disperse them uniformly, and impregnating under vacuum said lubricant into pores in a porous slide bearing. This method makes it possible to improve the penetration of grease into the bearing, to lower its apparent viscosity and to improve the impregnating efficiency.

Abstract: Disclosed is a coextruded, fire-resistant, composite structure of adjacent, alternating first and second layers wherein the first layer comprises a thermoplastic foam and second layer a thermoplastic material with such second layers containing a quantity of a brominated fire retardant sufficient to enhance the flame retardancy of the composite structure. Incorporation of the fire retardant into the thermoplastic material layers allows a fire-resistant foam structure to be made using water as a blowing agent for the first layers while avoiding serious corrosion problems encountered when incorporating both brominated fire retardants and water in the same foam structure. Further disclosed are processes for making the above described composite structure. Further disclosed is a composite flow melt expandable into the above-described composite structure.

Abstract: A method of forming a composite material by providing a quantity of first particles of a binder material and a quantity of second particles of a primary material having a softening temperature substantially in excess of the softening temperature of the binder material. The first and second quantities of particles are combined into a substantially uniform mixture. The uniform mixture is heated in the absence of pressure or shear sufficient to convert the binder particles, to a temperature substantially above the softening point of the binder material but less than the softening temperature of the primary material. Thereafter, pressure and shear are applied to the heated mixture sufficient substantially immediately to convert at least a portion of the binder material particles into a substantially continuous webbing structure or force the formation of point-bonds.
