Polyesters are combined with UV-stabilizing substances in order to produce an end product, such as a film, sheet, ribbon or filament, by mixing polyester granules and the UV-stabilizing substance in powdered form at an elevated temperature such that at least the exterior surface of the polyester granules is soft, thereby to cause the powdered UV-stabilizing substance to adhere to the individual po...

PURPOSE:To prevent a fault such as a system runaway by initiating an interruption at a specific period during the execution of an application program, storing the execution address of a microprocessor (MPU) at the start of the interruption and making specific checks, and reading out the execution address at the end of the checks. CONSTITUTION:The address bus 3 and data bus 2 of an MPU1 to be check...

A sweatband formed by a doughnut-shaped band of stretchable, perspiration absorbent fabric disposable about a portion of the body of the user. The hollow circular interior defines a compartment for holding small articles such as keys, driver's licenses and money. An opening in the band provides access to the interior compartment, and a zipper sewn to opposed sides of the opening allows the opening...

The present invention is directed to a clear, flexible, coated, biaxially oriented polyester film comprising a polyester film support and a radiation curable silicone coating on at least a portion of the support. The radiation curable silicone coating is derived from d dispersion of colloidal silica in an alcohol-water solution of the partial condensate of specified silanols and multifunctional ac...

A blend of an E/X/Y copolymer, where E is ethylene, X is a vinyl ester, and Y is carbon monoxide or sulfur dioxide, with a polymer of vinyl halide or vinylidene halide is foamed and cured by dispersing in the blend a blowing agent and sulfur or a sulfur-releasing agent and heating the blend containing those additives at 100 DEG -180 DEG C. for a sufficient time to produce curing and foaming. This ...

This invention relates to a process for producing phenolformaldehyde foams, also known as phenolic foams, of improved properties. The inventive feature resides in using a controlled combination of the various components in the curing reaction mixture and in controlling the temperature within the mass of the curing mixture. The process is applicable to production of block or laminated foams. Phenol...

PURPOSE:To achieve a smaller differential limiting torque at low speeds and a larger torque at intermediate and high speeds by an arrangement in which the differential limiting torque is transmitted between differential gears and a differential large gear at a predetermined vehicle speed. CONSTITUTION:Friction plates 17, 18 which are slidable in the axial direction are disposed in a bulging part 1...

A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles. The water causes hydrogen bonding between the films. Paper mill sludge or biberized waste paper is moistened with water in blender 33, agglomerated in rotating drum 41 ...

Foams are prepared from a linear low density polyethylene and, optionally, other olefinic polymers, such as a low density polyethylene using a chemical cross-linking agent. The resulting cross-linked polyethylene foams exhibit an excellent balance of properties at generally lower densities than foams prepared from low density polyethylene only.

A method of producing a phenolic foam composition comprises reacting (A) an aqueous solution of a reactive phenolic resin having 65-85% wt. solid solution (B) a foaming agent and (C) a reactive acid hardener wherein the ratio of component (A) to component (B) is from 4.5:1 to 9.3:1 and the ratio of component (A) to component (C) is from 6.5:1 to 7.5:1. The phenolic foam composition which has ex...

Process Of Making Articles Of Foamed Polymethyl Methacrylate The invention relates to a process of making articles of foamed polymethyl methacrylate (PMMA). In a first process stage a mixture comprising monomeric methyl methacrylate, plasticizer, preferably liquid foaming agent and catalyst is polymerized by heating and/or irradiation to form a foaming agent-containing solid body. In the second pr...

PROCESS FOR IMPROVING STEEL-EPOXY ADHESION The present invention is directed to a method for improving the adhesion of epoxy resins to steel substrates which comprises first removing the oxide surface layer, preferably by chemical means, and then pretreating the substrate with a solution of at least one coupling agent selected from the group consisting of .beta.-diketones and mercaptoesters. The i...

Films especially useful for the stretch wrapping of pallet loads are prepared from compositions consisting essentially of a linear low density polyethylene resin free of any polymerized vinyl acetate groups and from about 0.3 to about 3.0 wt % sorbitan monooleate based on the weight of the resin.
