Abstract: A puncture and cut resistant composite material comprising at least one elastomeric layer containing a plurality of flat platelets oriented substantially parallel to the plane of the elastomeric layer, wherein each of the platelets is a small, thin element substantially impervious to normally encountered puncturing and/or cutting by sharp objects, and wherein the platelets by their mutual overlap substantially cover any surface to which the composite material may be applied. This new composite material is particularly well-suited to the formation of gloves.

Abstract: An iron powder composition comprising an iron powder coated with a substantially uniform coating of a thermoplastic material and admixed with a boron nitride powder and a method of utilizing the mixture to produce a magnetic core component is provided. The iron powder mixture is formulated with up to about 1% by weight of boron nitride which reduces the stripping and sliding die ejection pressures during high temperature molding and also improves the permeability of the magnetic part over an extended frequency range.

Abstract: A rubber article formed from a rubber composition having a rubber component is provided wherein the article has a texture coating thereon. A texture coating mixture is formed from a mixture of a rubber composition having a rubber component substantially the same as employed to form the rubber article, and rubber particles also having a rubber component substantially the same as that of the rubber article. A method of forming a rubber article is also provided which includes coating a rubber article with such a texture coating mixture.

Abstract: A metallized film combination of an oriented polymeric substrate layer having on one surface thereof a coating of a blend of (a) a vinyl alcohol homopolymer or copolymer and (b) an ethylene-acrylic acid copolymer, the coating blend having a metal layer thereon. The method involves coating the substrate after the substrate has been machine direction oriented and before the combination is transverse direction oriented followed by TD orientation and finally by depositing a metal layer on the blend surface.

Abstract: Ferromagnetic metal particles the surface layer of which comprises laminatedly covered films of a ferrite compound having a spinel structure of at least one metal selected from cobalt, zinc, manganese, aluminum, chromium, nickel and copper and iron and a preparation process thereof.The particles can be used as a high density magnetic recording medium.

Abstract: Whiskers having a diameter of 0.1-10 .mu.m and a length of 5-200 .mu.m are pelletized and granulated into agglomerates which have a size of 0.1-10 mm and a bulk density of 0.2-1.0 kg/liter.To pelletize, powders of whiskers are moistened with water while mixing to form primary aggregates. Then, the powders and the primary aggregates are subjected to a rolling movement to cause the primary aggregates to grow into secondary aggregates having desired size distribution. Finally, the secondary aggregates are dried to obtain pelletized or granulated agglomerates of whiskers.Handling of whiskers is facilitated because the agglomerates are less bulky and less likely to fly up in the air. When blended into molding materials for fiber reinforcement, however, the agglomerates are readily disintegrated back into separated individual fibers to provide homogeneous dispersion.

Abstract: In a phosphor for a cathode-ray tube, a composition containing SiO.sub.2 and at least one element selected from the group consisting of indium, zirconium, and antimony is adhered on the surfaces of phosphor particles.

Abstract: A coated refractory composition for making high quality preforms comprising a refractory material selected from a metal refractory carbide, metal refractory nitride, metal refractory boride or diamond having a coating layer of hydrous alumina or a coating layer of anhydrous crystalline alumina, and to a method for enhancing dispersibility and improving oxidation resistance of such compositions.

Abstract: Disclosed is a configuration for a polymer pellet having improved reactivity for solid-state polymerization and less tendency to stick during processing with heat. The pellets have a reduced path length for volatiles to travel to the exterior of the pellet, and reduced contact area in a packed condition.

Abstract: Molded article having improved thermal resistance and strength formed from a homogeneous mixture comprising from about 5 to 75 percent by weight polybenzimidazole and from about 95 to 25 percent by weight of a polyaryleneketone. These articles are obtained by injection molding techniques.
