  • Wind turbine
    Patent number: 4021135
    Abstract: A wind turbine including a reaction type turbine wheel instead of an impulse type turbine which is normally used for receiving the wind and more efficiently deriving power therefrom and an augmenter means for producing a vortex downstream of the turbine at the exit of the turbine to increase the pressure differential across the turbine thereby increasing the power that may be extracted from the wind.

  • Means for suppressing cavitation in a high pressure relief valve
    Patent number: 4016898
    Abstract: The suppression of bubble formation and cavitation in the fluid passing through a high pressure relief valve is achieved by a back pressure valve in the relief valve discharge line. The back pressure valve has differential area pistons which maintain a back pressure of a fixed ratio to the high pressure at the relief valve inlet, this ratio being at least 1:3.
