  • Patent number: 8753100
    Abstract: A fluid transfer engine employs a case with a cylindrical inner wall having an operating radius extending from a case axis. A main rotor is carried within the case and incorporates a lobe with a major radius equal to and concentric with the operating radius of the case, the main rotor having a minor radius defining a body. Two peripheral rotors are diametrically opposed with respect to the case axis and rotate within rotor chambers extending from the case. Each peripheral rotor has a radius equal to the minor radius and a center of rotation located at twice the minor radius from the case axis. Each of the peripheral rotors rotates in uniform circular motion with the main rotor in sealing contact with the body and incorporates a sculpted recess for receiving the lobe of the main rotor.

  • Publication number: 20100276935
    Abstract: A wind or water turbine mounted atop a support tower or tethered underwater drives a hydro-pumping system. The turbine converts wind or water energy into a driving torque applied to the hydro-pump. The hydro-pump forces water through a pipe transmission system to an onshore facility. On shore, the resultant pressurized fluid-flow propels a hydroelectric generating system to produce electricity or may first be used in a Reverse Osmosis desalinization process and the byproduct in part used to propel a hydroelectric generating system to produce electricity. The cold-water discharge from the hydroelectric generating system and/or from the desalinization process is used for onshore district or power plant cooling purposes.

  • Patent number: 5445258
    Abstract: A pulse actuated clutch and control arrangement for coupling and decoupling a drive line of a vehicle relative to a wheel such as when shifting between two-wheel and four-wheel drive modes. The pulse actuated clutch has a coupling member that is permanently engaged with one of a driven member and a driving member. The coupling member is movable in a first direction to engage one of the driven and driving members and is movable in a second direction to engage both the driven and driving members. The coupling member is moved in the second direction by a first pulse of air pressure applied thereto. Formations of the piston assembly and the driven member cooperatively latch the piston in the second position to maintain the coupling member in engagement with both the driven and driving members following first pulse of air pressure. A second, greater magnitude pulse of air pressure moves the primary piston further to unlatch the piston and uncouple the driven member from the driving member.
