Abstract: A sustained release pharmaceutical formulation is disclosed. The formulation comprises a water soluble medicament and a polymer mixture comprising a first component of about 80 weight percent polyvinylacetate combined with about 20 weight percent polyvinyl pyrrolidone, of the total weight of the first component, combined with a second component of a cellulose ether polymer.

Abstract: In a method for the temperature regulation of an air conditioning system having a condenser, an evaporator, an expansion device and a compressor, the stroke of which can be set via a valve, the temperature in the region of the air outlet of the evaporator is measured and a desired temperature is set by a controlling of the valve. The temperature regulation additionally takes place in dependence on the refrigerant pressure.

Abstract: An improved control method for an electronically controlled variable displacement refrigerant compressor, where the control has normal and high speed displacement control modes, with smooth transitions between such control modes. The displacement control mechanism is in the form of a solenoid valve, and the valve is pulse-width-modulated (PWM) at a variable duty cycle to regulate displacement of the compressor. When the compressor is operating in a normal speed range, a first control mode determines a normal PWM duty cycle to satisfy cooling demand; when the compressor is operating in a high speed range, a second control mode determines an alternate PWM duty cycle based on compressor speed. The solenoid valve is operated in accordance with the duty cycle corresponding to the lower displacement. A smooth transition from the normal control mode to the high speed control mode is achieved by scheduling the alternate duty cycle as a function of compressor speed.

Abstract: An incorporable hydromotive assembly for a water storing dam or related engineered structure includes a siphon draft conduit with ascending-descending branches adapted to be archingly positioned over a water storing structure for conveying water through the hydromotive assembly to actuate same. The assembly includes chambers defined around its structural body which can be filled with fluid to sink it, or with gas to float it. The incorporable ascending-descending siphon draft conduit includes structure for interchangeably permitting it to be archingly positioned over a plurality of dams or related water storing structures. The method of positioning the incorporable and transportable assembly at said dams for purposes of power generation is described.

Abstract: A submersible hydromotive assembly is provided for an energy storing dam and includes chambers defined in its structural body which can be filled with water to sink the assembly or with gas to float it. Additionally, the hydromotive assembly has a machine hall with auxiliary equipment required to start, maintain in running condition and stop a turbine-generation set. Also included is the method of submerging and positioning the submersible hydromotive assembly at the water passage flow path of a dam.

Abstract: A thrust or support bearing arrangement with means for forming a frozen layer of lubricant thereon to define a reduced-friction running surface for a member to be supported thereby. The formation of a frozen layer of lubricant in sealing arrangements and the use of such bearings and seals in turbines or pumps are also described.
