  • Publication number: 20100300761
    Abstract: Sleeves, stabilizers and other well tools may be formed with fluid flow paths or channels extending through one or more blades disposed on the exterior portions of such well tools. The blades and associated fluid flow paths extending therethrough may allow optimum fluid flow rates and volumes to enhance lifting of formation cuttings and downhole debris along with cleaning exterior portions of the well tool and an associated rotary drill bit. Location, configuration, orientation and/or dimensions associated with such blades and associated fluid flow paths or channels may also be modified to provide an enlarged pad or contact surface on exterior portions of one or more blades while maintaining desired fluid flow rates and volumes over exterior portions of the well tool. Such pads or contact surfaces may have optimum surface areas for contacting adjacent portions of a wellbore during directional drilling of the wellbore.

  • Patent number: 7823287
    Abstract: The syringe pump comprises a receiving position for a syringe. The piston plate of the syringe is moved by a drive head which is fastened to a drive rod. For locking the piston rod prior to fixing the piston plate in the drive head, a braking element is provided on a syringe holding head. The syringe holding head further serves for determining the respective syringe size. After placing the syringe holding head against a syringe cylinder, the brake element is actuated to temporarily engage the piston rod and fix it relatively to the syringe cylinder.

  • Publication number: 20100263210
    Abstract: A method of improving hot water supply performance of a water heater is provided. The method includes coupling an outlet port of a water tempering device to the cold water inlet port of a water heater for delivering cold water from the cold water supply line into the water storage tank. The inlet port of the tempering device is coupled to the hot water outlet port of the water heater for receiving hot water from the water storage tank to the hot water supply line. A conduit of the tempering device is positioned between the inlet and outlet ports of the tempering device for diverting a portion of the cold water delivered from the cold water supply line into the conduit. The tempering device mixes the diverted cold water with the hot water received from the water storage tank, and delivers the mixed water into the hot water supply line.

  • Publication number: 20100252002
    Abstract: In a fuel injector, a body has formed therein a spray hole and a fuel supply passage. Fuel supplied to the fuel supply passage is delivered to the spray hole. A fuel pressure sensor produces a signal indicative of a pressure of the fuel. First terminals are attached to the fuel pressure sensor, and include a terminal for outputting the signal. The fuel pressure sensor is threadedly installed in the body while the plurality of first terminals are rotated about a preset axis. A connector includes a housing attached to the body, and second terminals supported by the housing for external electric connection of the fuel pressure sensor. Electrodes are each arranged to extend around the preset axis in a circular arc. Each of the electrodes electrically connects a corresponding one of the first terminals to a corresponding one of the second terminals.

  • Patent number: 7802584
    Abstract: A fuel injector comprising a hollow body for housing a metering valve with a calibrated pipe for outlet of the fuel from a control chamber. The calibrated pipe is normally kept closed by a shutter controlled by an electromagnet comprising a magnetic core and an electric coil housed in an annular slot of the core. The coil outer cylindrical surface forms a gap with the annular slot so as to be lapped by the fuel coming out of the calibrated pipe. The coil comprises a bobbin having a pair of appendages for supporting electric supply plugs, which are englobed at least in part in a block of non-magnetic material. The bobbin has a substantially cylindrical rib, one flange adjacent to an end portion of the plugs, and another flange having a smaller diameter that forms a passage for the fuel between the calibrated pipe and the gap.
