20110110797 | SYSTEM AND METHOD FOR WATER EXPULSION FROM UNDERWATER HYDROPOWER PLANT AND HYDROPOWER PLANT ASSOCIATED THEREWITH - Systems and methods relate to utilizing fluid potential energy to produce large scale and sustainable hydroelectric power by employing a Cho-Venturi hydraulic ram (CVHR). The CVHR system includes a Cho-Venturi tube (CVT) in which a primary flow from a fluid at a head pressure at a depth in a body of the fluid combines with a recirculation flow in a throat section of the CVT. A pressure higher than the pressure outside the plant is generated at the end of a diverging section the CVT, which enables expulsion of the fluid discharged from hydraulic turbines under atmospheric pressure to the fluid depth while another portion of the fluid is recycled for power generation. | 05-12-2011 |

20120057995 | SIDE-CHANNEL COMPRESSOR WITH SYMMETRIC ROTOR DISC WHICH PUMPS IN PARALLEL - The present invention provides a pump comprising a regenerative pumping mechanism having a generally disc-shaped rotor mounted on an axial shaft for rotation relative to a stator. The rotor has first and second surfaces each having a series of shaped recesses formed in concentric circles thereon, and a stator channel formed in a surface of the stator which faces one of the rotor's first or second surfaces. Each of the concentric circles is aligned with a portion of a stator channel so as to form a section of a gas flow path extending between an inlet and an outlet of the pump, and the rotor divides the section of flow path into sub-sections such that gas can flow towards the outlet simultaneously along any sub-section, channel or rotor side. As a result, the gas being pumped flows in a parallel fashion along both surfaces of the rotor. Thus, this configuration can provide a pumping mechanism where gas pressures on either side of the rotor can be substantially equal or balanced. | 03-08-2012 |

20140356194 | AIRLIFT PUMP WITH HELICAL FLOW PATTERN - The airlift pump with helical flow pattern includes a nozzle body having a fluid passage therethrough. A plurality of air or gas injector nozzles surrounds the central passage. The outward side of each nozzle is tangent to the fluid passage wall through the body to produce circumferential flow in the fluid passage. Each of the air injector nozzles is also inclined in the direction of flow through the body, the tangential inclination resulting in a helical flow pattern through the body. The centrifugal force generated by the circumferential and helical flow through the body results in a pressure decrease through the core of the fluid passage, thereby enhancing entrainment of fluid into the device to increase its efficiency. The fluid passage through the nozzle body is devoid of any structure, and the inlet end of the passage is smoothly radiused to further increase the efficiency of the device. | 12-04-2014 |
