Abstract: A rotary pressure production turbine for pressurizing a hydraulic fluid is disclosed comprising a plurality of piston assemblies. Each piston assembly comprises a hollow needle piston shaft having through which hydraulic fluid is moved from a low pressure volume to a high pressure volume as the piston shaft moves in a first direction. A rotary actuator actuates each piston shaft. From the high pressure volume, hydraulic fluid is moved to a common high pressure header and delivered to an aspirated accumulator where the fluid can be stored and subsequently utilized. In some embodiments, the fluid is utilized to operate an electric generator for use in a hybrid-electric vehicle. In some embodiments, the rotary actuator is driven by an internal combustion engine, while in others the rotary actuator is driven by a vehicle drive train in a regenerative braking application.

Abstract: A ceiling fan support for supporting a fan in a hole through a ceiling. The support is comprised of telescoping sections and is insertible through a hole in the ceiling and has teethed braces at each end adapted to be situated against a pair of spaced joists in the ceiling on each side of the hole. A tool is inserted into aligned holes in the telescoping sections and one of the telescoping sections is moved longitudinally until teeth on the braces dig into the joists thereby firmly supporting the support in the hole in the ceiling while a constant downward pressure is exerted on the telescoping sections maintaining them in fixed telescoped position.
