| The invention relates to a liquid ring pump (10) for transporting liquids. Said pump comprises a first housing element (11) on the drive side and a second housing element (12) on the front side, said housing elements being interconnected by means of a tongue and groove arrangement (38) and surrounding a working chamber (15). At least one impeller (16) provided with blades (27) is rotatably arranged in the working chamber (15). Said pump also comprises control means (22) which define a suction chamber and a pressure chamber (25,29) inside the pump. The inventive liquid ring pump is characterised in that the tongue and groove arrangement (38) is centrally embodied in relation to the rotational axis (13) of the impeller (16). The central engagement of the two housing elements significantly reduces the production and assembly costs as two excenters do not need to be fitted together. | ||||||

© A liquid ring pump with a conical or cylindrical port member (40) has a vent-recirculation port in the port member in addition to the conventional intake and discharge ports (42, 46). The vent-recirculation port communicates with the compression zone of the pump and is connected to a reservoir of pumping liquid maintained in the discharge portion (68) of the pump head (14a). When the pump is operating at relatively low compression ratios, the vent-recirculation port acts as a vent to prevent overcompression of the gas in the pump. At relatively high compression ratios, the vent-recirculation port recirculates pumping liquid from the reservoir, thereby increasing the maximum attainable compression ratio. |

| A system for distributed utilities including electrical power and water. A generation device is provided for converting an available resource to a desired utility; the resource may be water, in which case the generator is a purifier for purifying untreated water, or, alternatively, the generator may convert a fuel to electrical power. In either case, an input sensor is provided for measuring input to the generation device, while an output sensor is provided for measuring consumption of output from the generation device. The monitoring system has a controller for concatenating measured input and consumption of output on the basis of the input and output sensors. Measured parameters are telemetered to a remote site where utility generation and use are monitored and may also be controlled. At least a portion of the electrical power capacity of the electric generation unit may power a water purification unit such as a vapor compression distillation unit, and heat output of the electric generation unit may supply heat to the water purification unit. | ||||||

| A modular liquid ring pump has a liquid ring overload protection system including a passage from a working chamber directly to the pump discharge passage and a mechanical relief valve configured to release liquid from the working chamber during compressor overload. The liquid ring pump, when configured to have two stages, has an inter-stage by-pass system that includes an opening in an inter-stage passage and a pressure sensitive mechanical valve that allows the discharge of a first stage compressor to flow directly to the pump discharge at start up or during low pressure operation. The liquid ring pump's modular construction may be easily configured from a single stage pump to a two-stage pump and vice versa by using the same bearings, head, and drive system and only changing the body, cone, and rotor. | ||||||

| A method and at least two devices demonstrate improvements to energy extraction from a compressible working fluid in a liquid ring heat engine, which has a rotor mounted in a case. A space in the case is occupied by a liquid that establishes a liquid ring piston for the rotor. The rotor defines at least a first and a second operating zone. In the first zone, the working fluid is expanded against the liquid and, in the second zone, the working fluid is re-compressed. Between the two zones, the working fluid is cooled. In one device, the cooling step occurs on the rotor in a third zone. In another device, the cooling occurs outside of the case. | ||||||
