Abstract: A composite material including a thermosetting resin and a fibrous filler material. The composite material is preferably fabricated by dry mixing the thermosetting resin, in powdered form, with the fibrous filler material, and applying an elevated pressure to the dry mixture. The thermosetting resin preferably cures while the mixture is subjected to the elevated pressure. The dry mixture may also be subjected to an elevated temperature. The hardened mass of composite material may be formed into the shape of a desired article of manufacture as an elevated pressure is applied thereto. Alternatively, an article of manufacture may be fabricated from the block of the composite material after formation of the block. The composite material will adhere to glues that have conventionally been used to adhere pieces of wood or wood-like material to one another.

Abstract: A system for interconnecting a surface power source with a downhole pump in an oil well or similar fluid pumping installation uses a cable and associated connectors. The cable is constructed from a plurality of helically preformed wires which are heat treated and surrounded with a corrosion and abrasion resistant material. This construction provides the cable with sufficient stiffness that it does not slump, buckle or coil when inserted in the well, and with sufficient density that it is not buoyant in the fluid being pumped, but yet with sufficient flexibility that it can be unwound from a reel for insertion into the well and rewound on the reel for extraction from the well. The connectors, which are used at the ends of the cable, secure and protect the cable and allow easy adjustment of its length for optimum pump efficiency.

Abstract: A process for manufacturing a hand tool includes the steps of assembling a tool handle to a molded composite handle adapter to form a tool handle assembly, and attaching the assembly to a tool head utilizing removable fasteners.
