Publication number: 20120111008Abstract: A diaphragm for a steam turbine is disclosed that has at least one arc of admission. The arc of admission has a plurality of nozzles arranged about the circumference of the diaphragm and are configured to eject a working fluid at succeeding rotor blades axially-spaced from the diaphragm.

Patent number: 7293314Abstract: A method and apparatus for enabling a pool cleaner to travel through a water pool to collect dirt and other debris from the water and/or pool containment wall. The cleaner defines a suction passageway having an inlet open to pool water and an outlet adapted to be coupled via a flexible hose to the suction side of an electrically driven pump.

Patent number: 7223069Abstract: A rotary device having an inlet adapter for connecting the device to a pressurized fluid source, a turbine rotor, and an input passage. The input passage provides fluid communication between the input adapter and the turbine rotor, has a first end proximate the inlet adapter and an opening downstream from the first end, and has a generally constant cross sectional area between the first end and the opening.Type: GrantFiled: July 12, 2005Date of Patent: May 29, 2007Assignee: Air Turbine Technology, Inc.Inventor: Kemma S. Dodds

Patent number: 7210902Abstract: A two-way air pump includes a housing, an air flow controller, a check valve, and a valve actuator. The housing confines an air control chamber, and is formed with a valve hole, an air outlet and an air inlet. The air flow controller confines an air impeller chamber, is formed with a hole set, is mounted rotatably in the air control chamber, and is rotatable between inflating and deflating portions to control fluid communication among the valve hole, the air outlet, the air inlet and the air impeller chamber. The check valve is mounted in the valve hole, and is movable between control-enabled and control-disabled positions. The valve actuator is provided on the air flow controller, and drives the check valve to the control-disabled position when the air flow controller is rotated to the deflating position. An air impeller is mounted rotatably in the air impeller chamber.Type: GrantFiled: October 5, 2004Date of Patent: May 1, 2007Inventors: Rong-Jyh Song, Tsung-Ping Yen

Patent number: 7201557Abstract: A pressure exchanger for the transfer of pressure energy from a high pressure fluid stream to a lower pressure fluid stream wherein a generally cylindrical housing contains a rotor having a plurality of channels extending axially therethrough and a pair of end covers which slidingly and sealingly interface with respective end faces of the rotor. The end covers are supported against deformation by high pressure upon the end covers in an inward direction, as by exerting a balancing comparable outward axial force upon inward surfaces of the end covers through the employment of pressure-balancing chambers that are in communication with a high pressure fluid region at one end cover.Type: GrantFiled: May 2, 2005Date of Patent: April 10, 2007Assignee: Energy Recovery, Inc.Inventor: Richard L Stover

Patent number: 7174716Abstract: A machine designed as a centrifugal compressor is applied as an organic rankine cycle turbine by operating the machine in reverse. In order to accommodate the higher pressures when operating as a turbine, a suitable refrigerant is chosen such that the pressures and temperatures are maintained within established limits. Such an adaptation of existing, relatively inexpensive equipment to an application that may be otherwise uneconomical, allows for the convenient and economical use of energy that would be otherwise lost by waste heat to the atmosphere.Type: GrantFiled: November 13, 2002Date of Patent: February 13, 2007Assignee: UTC Power LLCInventors: Joost J.

Patent number: 7165936Abstract: A multiple-passage turbine nozzle with desired predetermined flow properties may be provided with an adjustment member in one or more of its passages to limit the flow therethrough. Turbine nozzle flow is an important performance characteristic that may be difficult to control by conventional drilling or machining manufacturing methods. The adjustment member may protrude into a nozzle passage, thereby reducing airflow through the nozzle passage. The amount of protrusion is variable and is selected to provide a desired partial or total occlusion of an associated passage at the time of manufacture of the turbine nozzle to compensate for variations produced by the conventional manufacturing techniques. The turbine nozzle according to the present invention provides simple and convenient calibrated adjustment of the predetermined flow that may be allowed to pass through a turbine nozzle onto a turbine wheel of a turbo machine.Type: GrantFiled: August 16, 2004Date of Patent: January 23, 2007Assignee: Honeywell International, Inc.Inventor: David G.

Patent number: 7162763Abstract: A method and apparatus for enabling a pool cleaner (60) to travel through a water pool to collect dirt and other debris from the water and/or pool containment wall (88). The cleaner (60) defines a suction passageway having an inlet (74) open to pool water and an outlet (78) adapted to be coupled via a flexible hose (30) to the suction side of an electrically driven pump (26). A resulting suction flow, from the inlet (74) to the pump, functions to (1) carry dirt and other debris to a filter (41) and (2) to drive a turbine (80) for propelling the cleaner (60). In accordance with the invention, the suction passageway inlet (74) includes an orifice defining a physical flow area A1 and configured to create an “effective” flow area A2 smaller than A1, downstream from the orifice. The small effective flow area A2 creates a water flow of sufficient velocity to efficiently drive the turbine (80) whereas the larger physical flow area A1 permits debris to pass more readily.Type: GrantFiled: May 8, 2001Date of Patent: January 16, 2007Assignee: Henkin-Laby, LLCInventors: Melvyn L.
