  • Patent number: 9822699
    Abstract: A hybrid turbocharger includes a first power conversion unit to convert a direct-current power into alternating-current power to be output to a generator motor, a smoothing capacitor between direct-current buses, and a control unit that controls the first power conversion unit so as to cause actual generator motor speed to comply with an engine speed command of the generator motor input from an upstream controller during a motoring operation of the generator motor. The control unit changes the engine speed command to a value which is equal to or greater than the actual generator motor speed if the engine speed command of the generator motor is less than the actual generator motor speed and a direct-current bus voltage is equal to or greater than a predetermined first threshold value during the motoring operation. Accordingly, the direct-current bus voltage can be prevented from increasing during the motoring operation.

  • Patent number: 9765755
    Abstract: Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.

  • Patent number: 9309785
    Abstract: A method and system using at least two different working fluids to be supplied to an expander to cause it to do mechanical work. The expander is started by providing a compressed gaseous working fluid at a sufficient pressure to the expander. At the same time the compressed gaseous working fluid is provided to the expander, a second working fluid that is liquid at ambient temperatures is provided to a heater to be heated. The second working fluid is heated to its boiling point and converted to pressurized gas Once the pressure is increased to a sufficient level, the second working fluid is injected into the expander to generate power, and the supply of the first working fluid may be stopped. After expansion in the expander, the working fluids are is exhausted from the expander, and the second working fluid may be condensed for separation from the first working fluid. Control circuitry controls the admission of the first and second working fluids responsive to monitoring the load on the expander.

  • Patent number: 9255869
    Abstract: The invention relates to the method of feeding the air, or fluid of lower density, into the duct (2) by means of tubes separated one from another in such a way that there should be water, or liquid fluid, between them, so that this bathes at least part of its walls. In other words, similar to the stalks of a bouquet submerged in water, and at whose ends, instead of flowers, air bubbles exit, these being produced at the air inlet at the extremity of the stalk or tube. It relates more specifically to the method of feeding the lower-density fluid by means of tubes which at their base are grouped, close to each other or touching, and at their outlet extremities are separated, as if forming a bouquet, in such a way that the separation distance of the extremities of the tubes, between axes of symmetry, is approximately the diameter of the bubble.

  • Patent number: 9228764
    Abstract: A cooling head for a temperature-controlled phase change cooler has a main body, an evaporating chamber within the main body, at least two cap tubes and at least a heat source mounted onto the periphery of the evaporating chamber. With one of the cap tubes, the coolant is guided into the evaporating chamber, then the cooling head of the phase change cooler could be quickly cooled down due to rapid heat absorption characteristic of the evaporated coolant. In such a case, a heat source is used for heating by a control mechanism, and the temperature could be adjusted to a desired temperature point within the limited range of low temperature according to the user demands. When the preset temperature point is higher than normal temperature, the control mechanism could change properly the flux via one of two cap tubes, and provide proper amount of coolant for evaporative cooling.

  • Patent number: 9166458
    Abstract: The pump/generator apparatus and method provides a series of pump/generator devices, having magnets in place of conventional bearings, to generate electrical energy, creating a pump/generator for flowing liquids or gases. Stator coils on the outside of the housing gather electric current. The apparatus requires initial input power from an external power source to start the pumping and provides an initial external reservoir of liquid or gas flowing into the apparatus. A hollow turbine housing receiving flowing gas or liquid, encloses a freely spinning hollow drive cylinder. A helicoidal impeller gives the drive cylinder thrust to spin. Ring magnets vertically support the helicoidal impeller allowing the drive cylinder to float freely in the pipeline. Stator coils wind around and ring the exterior side of the housing to generate electric current.
