  • Patent number: 9976348
    Abstract: Downhole drilling often requires passing drilling fluid containing water mixed with mud through a downhole drill pipe. Such drill pipe may comprise cavities therein for working units such as motors, generators, solenoids and the like. It may be desirable to lubricate and cool such working units with water from the drilling fluid, however, mud particulate may damage such devices. The present invention comprises various embodiments of a dynamic seal assembly designed to allow fluid communication between a cavity and a fluid flow while blocking certain particulate matter within the fluid flow from entering the cavity. The fluid communication may occur through and the particulate matter may be blocked by a defined clearance between two complementary surfaces that are movable relative to each other.

  • 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: 9579980
    Abstract: A hydraulic pump powering system includes a mobile vehicle, a first electric current generator device, and one or more electric pump motors. The mobile vehicle has first and second prime movers. The first electric current generator device is disposed onboard the mobile vehicle and is configured to be mechanically coupled with the first prime mover to convert movement created by the first prime mover into first electric current. The one or more electric pump motors are configured to receive the first electric current to power a hydraulic pump. The second prime mover is configured to generate movement that is converted into a propulsive force that propels the mobile vehicle. The one or more electric pump motors are configured to receive the first electric current in order to power the hydraulic pump to pump a fluid into a pumping location located off-board the mobile vehicle.

  • Patent number: 9525375
    Abstract: Provided is a system for transporting an oil sand slurry, comprising a pump, upstream and downstream lines, a shaft connectable to the pump, a driving mechanism driving the pump and a regulator for regulating the torque applied to the shaft between positive and negative torque modes, to pump the slurry at higher or lower flow rates. Also provided is a method comprising pumping the slurry through a pipeline using a pump driven by a motorized shaft and adjusting the flow rate of the slurry by varying the torque applied to the motorized shaft between positive and negative torque modes. The oil sand slurry transportation system and method enable positive head (regular pump action) for normal and high flow rates and negative head (pump brake action) for low flow rates, which reduces system energy loss, pipeline wear, vapor breakout and sanding off.

  • Patent number: 9494127
    Abstract: A pumped storage power plant performs a pumping operation by using a pump turbine, upper and lower regulating reservoirs. An upper space of one of the reservoirs is sealable. The pumped storage power plant detects an air pressure in the upper space, first and second water levels of the one and the other reservoirs. A controller of the pumped storage power plant obtains information of the detected air pressure, first and second water levels, and an electrical energy input from an external grid and used during the pumping operation. A calculation water level of the one reservoir is calculated by using the first water level and the air pressure. The controller adjusts the air pressure such that a difference between the second water level and the calculation water level becomes a desired difference that is determined by a characteristic of the pump turbine depending on the input electrical energy.
