A spring member for use in a disc type friction coupling mechanism for urging the movable friction members associated with such devices toward their inoperative retracted positions, the spring member having a planar loop portion and at least one arm portion associated therewith, each of the arm portions being angularly displaced relative to the plane of the loop portion, the loop portion being rem...

A normally closed high pressure solenoid valve structure including a plunger pin spring-urged against a composite valve seat having a steel reinforcing ring positioned against the seat and backed up by a fixed spacer. The seat has a projecting neck with orifice. The steel reinforcing ring surrounds and contains any radial movement of the seat which is of elastic material softer than the plunger pi...

Control process for producing an aqueous slurry of solid carbonaceous fuel having a desired solids concentration for feed to a partial oxidation gas generator by grinding together in a size reduction zone a recycle aqueous slurry stream comprising carbon-containing particulate solids, a stream of solid carbonaceous fuel, and a specific amount of make-up water. No valves are in the line or path bet...

A recipe is provided for an aqueous inside and/or outside paint for green tires which are to be vulcanized in a mold in cooperation with a hot, pressurized inner bladder. The aqueous paint contains no silicone release agent, hydrocarbon solvent or rubber latex, but only an air bleeding pigment such as carbon black for the outside paint or mica for the inside paint, and surfactant which are blended...

An improvement over the cementitious composite material described in U.S. Pat. No. 4,482,385 consists in replacing the stainless steel particles with graded silicon carbide particles. The resulting material has a lower coefficient of thermal expansion, a greater thermal conductivity and an increased surface abrasion resistance as compared to the material described in the patent and is a lighter we...

Films or sheets are fabricated from blends of an ethylenic polymer or copolymer, a butene-1 polymer or copolymer, and a propylene polymer or copolymer which result in improved optical clarity, heat seal strength and peel seal characteristics.

Blends of polypropylene-poly(vinyl aromatic monomer) interpolymer with certain polymers and/or rubbers can be impregnated with blowing agents to give products which can be expanded under atmospheric steam conditions to give low density, fine cell structure foam particles.

Resilient foams based on melamine resins are prepared by foaming an aqueous solution which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent and then curing the foam. In this process, from 0.2 to 4% by weight of an alkali metal, alkaline earth metal or aluminum salt of an organic, preferably polybasic acid, of a polyphosphoric acid or of a b...

Thermoplastic resinous foams having improved resistance to oxidation are provided by the incorporation into such foams of a polyvinyl ether of a C6-30 alcohol.

Prepregs which are tacky to dry to the touch can be prepared by impregnating a solid reinforcing material with a liquid, solvent-free composition containing (a) an epoxide resin, (b) a photopolymerizable compound, (c) a heat-activatable curing agent for the epoxide resin (a) and, if appropriate, a photopolymerization catalyst for the photopolymerizable compound (b), and the composition is exposed ...
