The periurethral adapter is characterized by a pair of laterally spaced flanges which lie between the labia minora, and in which the posterior vertically extending surfaces of the flanges which are received between the labia minora and engage the urinary meatus, are positioned to assist in preventing leakage.

Abstract: The process of increasing the efficiency and output of a gas-turbine having blades in a combustion chamber which includes cooling the gas-turbine blades with a liquid-fuel and mixing the fuel used for cooling with air in the combustion chamber and burning the mixture and driving the turbine by the exhaust from the combustion chamber. Preferably the fuel is a liquid-gas such as hydrogen. The turbine may be cooled by injecting liquid-fuel onto its disk to provide a film coating which is centrifuged around the blades whereby the liquid will cool both the interior and exterior of the blades and the absorbed heat is introduced into the combustion chamber. The combustion chamber includes a plurality of air inlets. The turbine drives a compressor and the compressor and the air inlet may be cooled with the liquid-fuel, which may be cryogenically cooled. An improved jet engine which is convertible from a turbo to a ramjet is provided.

Abstract: A compact double-stage turbocompressor unit having a compressor section with two-stage, radially aligned rotors that are counter rotated and a turbine section with two-stage, radially aligned rotors that are counter rotated, the rotors of the low pressure compressor and turbine sections being interconnected and the rotors of the high pressure compressor and turbine sections being interconnected.

Abstract: A wall box mounted voltage controller used in conjunction with a remotely located dimmer module for controlling multiple loads. The controller utilizes a printed circuit board structure and a multiplicity of control operators extendable from the printed circuit board structure. Each operator is linked to a potentiometer which in turn generates a electrical signal to control the intensity of the load via the dimmer module. High and low trim mechanisms for each signal are supported to the printed circuit board structure and are readily available for mechanical adjustment.

Abstract: A two-cycle, internal combustion engine designed for operation in conjunction with high pressure supercharging for high temperature, high pressure combustion in one or more piston cylinders, the combustion chamber including a porous, floating liner displaced from the cylinder walls of the combustion chamber, the pistons having a concentric groove for receiving the floating liner on the compression stroke for insulating the wall of the piston cylinder from the hot gases of combustion.

Abstract: A device for detecting the level of heat generated by a lighting unit utilizing a sleeve possessing an end portion positioned adjacent to the exterior of the housing, an interior portion, and an exterior portion. A thermal protector is positioned at the interior portion of the sleeve at a selected distance from the exterior of the housing. Air is circulated between the exterior portion of the sleeve and the interior portion of the sleeve.
