Abstract: A control system for an hydraulic supercharger system. The control system is specially adapted to control a supercharger system comprising: (A) an hydraulic pump; (B) a supercharger comprising: an hydraulic turbine drive and a compressor driven by the hydraulic turbine drive; (C) a main hydraulic piping means providing a hydraulic circulation loop for hydraulic fluid to flow from said pump, to drive said hydraulic turbine drive, and back to said pump; and (D) a supercharger bypass system comprising a controlled bypass valve and a piping means to permit a portion of said hydraulic fluid to bypass said supercharger turbine drive. The control system includes a solenoid arranged to close and partially or fully open the controlled bypass valve. The solenoid may be controlled by a pressure switch connected to sense hydraulic pressure and to apply a voltage to said solenoid to open or close said valve upon said hydraulic pressure reaching a predetermined value. Since the hydraulic pressure increases with engine speed, it is a simple matter to adjust the control system to provide for the hydraulic fluid to drive the supercharger or to bypass the supercharger at any predetermined ranges of engine speed. The bypass valve may also be controlled based on engine throttle position. In another preferred embodiment where the turbocharger system comprising an air flow check valve which opens when a turbocharger is providing sufficient air to the engine, the bypass valve is also subject to control based on the position of the check valve, so that the hydraulic supercharger can be substantially bypassed when the turbocharger is able provide sufficient air to the engine.

Abstract: A very simple system to automatically control the flow of irrigation water. The stem of a water shutoff valve is controlled by a balance beam having two arms extending perpendicular to the axis of rotation of the valve stem. The angle between the two arms is about 135 degrees. At the end of the second arm is a water bucket. At the end of the first arm is a counter weight. When the first arm is horizontal, the water bucket is elevated and the valve is open. The water bucket collects a small portion of the irrigation water flow. When the bucket is substantially full, the second arm moves to a horizontal position, the counterweight is elevated and the valve is closed.

Abstract: A very high speed radial inflow hydraulic turbine drive. Inflow nozzles drilled in a nozzle body intersect a circular nozzle body exit surface, the centerline of each nozzle forming an angle of between 8 and 25 degrees with the tangent of the exit circle at the point of intersection. The turbine wheel of the drive is small. Its diameter measured at the tips of the blades is less than 2 inches. In a preferred embodiment, built and tested by Applicant, the wheel is only 0.80 inch diameter. This embodiment was tested with a turbine hydraulic fluid pressure drop of 700 psi and flow of 19.5 GPM. The 0.8 inch turbine produced 5.9 HP at 62,000 RPM driving the compressor portion of a TO4B-V turbocharger. The compressed air flow was measured at 11.3 pounds per minute (161.4 inlet CFM) at a pressure ratio of 1.41. During the test the acceleration of the supercharger was measured from idle to 62,000 RPM in about 1/2 second. This preferred embodiment utilizes a plastic-metal turbine wheel in which the plastic portion of the wheel other than the blades is solidly anchored within a metal containing wheel. In other preferred embodiments the turbine drive drives superchargers for supercharging internal combustion engines such as bus and truck turbodiesel engines. The superchargers provided by the present invention produce immediate response to engine demand for increased combustion air and will dramatically reduce smoke emission during low speed acceleration of these bus and truck engines as well as greatly improve engine efficiency.

Abstract: A shaft seal system is disclosed for isolating two regions of different fluid mediums through which a rotatable shaft extends. The seal system includes a seal housing through which the shaft extends and which defines an annular land and an annular labyrinth both of which face on the shaft so that each establishes a corresponding fluid sealing annulus. A collection cavity is formed in communication with the annular sealing spaces, and fluids compatible with the fluids in each of the two regions to be isolated are introduced, respectively, into the annular sealing spaces and collected in the collection cavity from which the fluid mixture is removed and passed to a separator which separates the fluids and returns them to their respective annular sealing spaces in a recycling manner. In the illustrated embodiment, the isolated fluid mediums comprise a liquid region and a gas region. Gas is removed from the gas region and passed through a purifier and a gas pump operative to introduce the purified gas through the labyrinth sealing annulus to the collection cavity. After passing to the separator, the separated gas is passed through a dryer from which the dried gas is caused to pass through the labyrinth sealing annulus into the collection cavity independently of the purified gas so as to insure isolation of the gas region in the event of sealing gas pump malfunction.

Abstract: A nuclear reactor includes a core submerged in a pool of liquid. Under normal conditions, coolant flows through the core without intermixing with the liquid in the pool. In the event of failure of the primary coolant circulation system, liquid from the pool flows through openings in the primary circulation system so as to cool the core by natural convection. Flow through the openings during normal operating conditions may be controlled regardless of the flow rate.

Abstract: A system for producing process heat which employs a high temperature gas cooled nuclear reactor and is adapted to provide process heat at temperatures higher than the reactor core temperature. The system includes a closed secondary loop having a working fluid heated to a first temperature by the coolant of the reactor core in an intermediate heat exchanger, and has a heat pump connected in the secondary loop which increases the temperature of the working fluid to a temperature above the core coolant temperature. Steam in an independent closed nuclear steam supply circuit is heated directly by the core coolant in a steam generator and provides steam for make-up driving power to the heat pump in the secondary loop. The steam supply circuit also supplies additional steam to generate electric power and process steam. The size of the intermediate heat exchanger is minimized to enable maximum utilization of the steam supply circuit.
