Abstract: A paint roller frame and cage assembly and method of manufacturing includes providing an assembly having a handle and a shaft extending from the handle, and forming a unitary cage having a radially outward surface for supporting a roller cover. The cage includes a first cavity located at an end of the cage proximate the handle and a second cavity located at an opposite end of the cage. Each cavity is defined within the radially outward surface and has a radially opening slot. A cover retainer is receivable through a first slot and into the first cavity. The cover retainer includes radially extending fingers that extend through the slot to engage an inner diameter of the roller cover and secure the cover to the cage. A fastener is receivable through a second slot and into the second cavity to hold the cage on the shaft.

Abstract: A waterjet orifice assembly is provided with a retaining hat which assembles over a head portion of a nozzle mount to capture a nozzle jewel between the mount and retaining hat so that when assembled in a nozzle assembly between a nozzle tube and a capture nut the nozzle jewel becomes securely held and centrally aligned within the assembly.

Abstract: A dynamic, self sustaining and self perpetuating, device for the production of motive force by combining cryogenic and thermodynamic principles into one system, keeping the systems separated, two open to atmosphere, the other closed, sealed, pressurized and utilizing special compounded fluids, which when alternately exposed to the heat of atmospheric temperature, then, to the coldness of a liquid or an air cooled condensor, first evaporates, then condenses. Rapid expansion during evaporation produces a high pressure vapor which operates an engine and a generator, which are an integral part of the closed system. Rapid condensation drastically reduces back pressure on the aft side of the engine, and the engine operates on the difference between the two pressures, producing electricity, or, the engine can be used as a direct drive for vehicles or equipment. Built in safeguards and alternatives are a part of the systems, assuring continuance of operation despite adverse conditions.
