Abstract: A flame spray powder of cobalt and molybdenum mixed metal agglomerates is produced by spray drying a slurry of molybdenum metal particles and cobalt oxide particles in an ammonium molybdate solution to produce agglomerates, and thereafter heating the agglomerates in a reducing atmosphere to convert the oxide particles to cobalt metal and the binder to molybdenum metal.

Abstract: Polymeric bodies having selected morphological properties are prepared by effecting an apparent increase in the glass transition temperature of the polymer to cause it to become glassy and manipulating the polymer while it is in the glassy state. In the preferred practice of the invention, the apparent increase in the glass transition temperature is a reversible function so that after the morphological properties of the polymer have been developed, the normal glass transition temperature of the polymer may be restored.The process of this invention finds utility in the preparation and formulation of polymers in powdered form; it provides a practical method for the formation of powders in unusual size ranges, which, in turn, makes possible the formation of shaped articles by novel processes; and it provides a simple method for making products, such as open-cell foams and surfaces in relief, that have unique physical characteristics.

Abstract: A fiber-bundle-filled thermoplastic composite and method of preparing such composite are described wherein the fiber bundles are randomly oriented in the flat plane of the composite and the fiber bundle integrity is maintained, said composite leading to better properties and fiber dispersion in manufactured articles prepared from said composite.

Abstract: In accordance with the invention, hollow pellets having outer surfaces of one material and inner surfaces of another material are manufactured by dropping drops of liquid into a bed of powder containing the material of which it is desired to make the outer surface portions of the hollow pellets and preferably also a binder, the liquid containing the material of which it is desired to make the inner surface portions of the hollow pellets. When the drops of liquid fall into the powder, the powder immediately forms a spherical shell around each drop so as to form the hollow pellets upon vaporization of the liquid. It is preferred that the powder additionally contain some sodium bicarbonate or the like and that the liquid be an aqueous acid solution such that, upon initial formation of the spherical shell of powder, the acid reacts with the sodium bicarbonate to generate carbon dioxide which causes the spherical shell to expand while yet additional powder coalesces onto the shell.

Abstract: Granular calcium hypochlorite particles having a core of calcium hypochlorite encapsulated in a plurality of layers of calcium hypochlorite are produced from an aqueous slurry of calcium hypochlorite by spraying a pumpable and sprayable slurry of calcium hypochlorite particles onto suspended particles of solid calcium hypochlorite above a moving bed of said particles in a fluidized bed. The solid particles coated with the slurry are heated to simultaneously evaporate and remove water from the slurry whereby said particles are coated with a layer of solid calcium hypochlorite.A portion of the moving bed of coated particles is removed from the spraying zone and further processed, if desired. In one embodiment, the coated particles with or without sizing are further dried to produce granular particles having the desired moisture content.

Abstract: The present invention relates to a process for the manufacture of chip boards especially multi-layer chip boards, using condensation resins as binders, and the products thereof the improvement including wetting powdered adhesive particles before applying the adhesive particles to wood chips.

Abstract: Aqueous polyester imide dispersions are prepared by allowing molten polyester imide to solidify and then comminuting it in the dry state to a particle size of 100 .mu.m or less, whereupon the particles are milled in water to a particle size of less than 5 .mu.um. The dispersions may be used for the manufacture of heat-resistant bonds and impregnations and for electrical insulation of metallic conductors. m.

Abstract: The invention relates to a method for producing loose-fill packing material in the form of hollow, substantially hemispherical bodies made from an extrudable, expandable synthetic plastic composition.

Abstract: The invention relates to magnetic discs in which first a non-magnetic intermediate layer and then the magnetic coating are applied by conventional methods to an aluminum disc. The intermediate layer applied to the non-magnetic metallic carrier disc is a hard non-magnetic coating which can be polished and which consists of a dispersion of a pulverulent mixture of finely divided inorganic non-magnetic pigments having a Mohs' hardness of at least 7 in a binder which can be cured and which provides firm cohesion of the pigment particles and good adhesion thereof to the non-magnetic base disc, the pigment mixture containing at least 3 percent by weight of corundum powder having a particle size of from about 1 to 20.mu.u. Magnetic discs with very thin magnetic coatings which possess good magnetic and mechanical properties and whose thickness varies only minimally are thus produced in a simple manner.

Abstract: This invention provides a novel granular asphalt which comprises granules having the size of from about 0.074 to about 10 mm and being in the shape of a polyhedron having at least one acute angle. The granular asphalt has excellent properties. In particular, it can be melted rapidly and easily with small thermal capacity and slight heating, without causing thermal decomposition, denaturing and air pollution. The granular asphalt is useful, for example, for producing asphalt compound, cutback asphalt, rubberized asphalt, etc., for use in water-proofing, paving, sealing, etc., and for making asphalt block, asphalt tile, asphalt roofing, tarpaulin paper, flooring sheet, paint and varnish, etc.

Abstract: Described are semipermeable microcapsules which comprise an outer semipermeable polymeric skin encapsulating a finely divided heterogeneous catalyst and a ferromagnetic material. The microcapsules are useful as magnetic, heterogeneous catalysts.

Abstract: A process is provided to form spherical thermoplastic particles that involves dispersing a thermoplastic powder in a liquid that is a partial solvent for the thermoplastic, breaking the dispersion into droplets, forming thermoplastic spheres by heating the droplets to a temperature sufficient to at least partially solubilize the thermoplastic and to evaporate the solvent. Unique products, including porous structures, may be produced from material formed by this process.

Abstract: A separator for a galvanic element wherein partially fused glass fibers are coated by a coating consisting of grains of thermo-hardening synthetic material immersed in a natural or synthetic latex to mechanically reinforce the knots in the glass fiber network resulting from partial fusion of the glass fibers without blocking the pores of the partially fused fiber network.

Abstract: Pellicles of para-xylylene polymers are used as the sole support media for masses of objects supported thereon. The supported objects can be combined with the pellicle either during the formation of the pellicle or after the pellicle has been manufactured. The composite article is used wherever it is desirable to provide a support media which has as little detrimental influence as possible on the intended function of the supported object.

Abstract: La.sub.2 O.sub.2 S particles are employed as carrier hosts in a cathodo-luminescent penetration phosphor composition for cathode ray display tubes. Tb and Eu ions are used in low concentrations as activators in the control of the red and green optical emission from within a film of the activated host material.
