The machining of the body of the gear pump/motor is accomplished in a low cost and efficient manner to produce a gear pump/motor that operates in air entrained oil without emitting undesirable noises.
Patent GB-2305529-A (GB)
Title: Radio pager
Inventor: NAGAKURA TOMIO
IPC: H04W88/02
Filed: 1996-09-26
Abstract: A radio pager includes a non-volatile memory 40 storing frequency information for each of a plurality of frequency bands for the confirmation of a frequency band. The frequency information are sequentially read out of the memory while frequency signals respectively corresponding to the information are sequentially fed to a frequency synthesizer 21, until frequency lock detecting means detects a frequency lock. The frequency band to which the locked frequency belongs is determined to be the frequency band assigned to the radio pager and is displayed 50 to the operator. Therefore, even before frequency information for allowing the synthesizer to output a desired oscillation frequency corresponding to a receipt frequency is written to the pager and when a frequency band particular to the pager is not labeled on the pager body, the operator can see the frequency band easily. This prevents the operator from writing frequency information in the ROM 40 of an inadequate radio pager to which a desired frequency band is not assigned.

Title: Remote control for a plug-dropping head
Inventor: HOLCOMBE MICHAEL W
IPC: E21B33/05
Filed: 1997-06-18
Abstract: An apparatus for dropping a pumpdown plug or ball is actuated by remote control, employing intrinsically safe circuitry. The plug or ball is dropped when a sleeve is released from its upper position by rotation of a lock pin 172 through 180{ which removes a shoulder on lock pin from a position supporting shoulder 168 on the sleeve. The lock pin 172 is rotated by an electric motor via reduction gear 236, shafts 238,246 and gears 242,248,202 and 200. The motor is actuated when a release signal (e.g. an infra-red signal) is received by the apparatus. Multiple plug-dropping heads can be stacked, each responsive to a discrete release signal. Actuation to drop the pumpdown ball or plug is accomplished even while the components are rotating or are moving longitudinally. Using the apparatus and method of the present invention, personnel do not need to climb up in the derrick to actuate manual valves. There is additionally no need for a rig floor mounted control panel with hydraulic lines extending from the control panel to remotely located valves for plug or ball release.

Title: Detecting gas influx into a wellbore
Inventor: OWENS STEVEN CRATUS
IPC: E21B47/10
Filed: 1994-08-18
Abstract: In a wellbore being drilled, influx of gas 747 is detected before blowout occurs. Surface acoustic transducer 743 transmits interrogating signals down the annular region 741 containing fluid. The acoustic signal is reflected either at markers affixed to the drill string 733 or at the drill collar 739. The reflected signal is received at surface transducer 743 and analysed. If the transmitted signal is frequency rich, the received spectrum shows which frequencies or bands have the highest S/N ratios. Influx of the gas 747 will alter these frequencies or bands and an abrupt change can be signalled to an operator by means of display at terminal 745. As an alternative the transmission could be between spaced transducers down the borehole. Also, instead of the channel parameters being monitored, the effect of gas on the signal itself may be detected.

Title: The piston compression ring assemblies being self-lubricated and self-adjusted
Inventor: WANG BAODONG
IPC: F16J9/16
Filed: 1996-05-03
Abstract: This invention relates to piston compression ring assemblies, each of which consists of a main ring element and an auxiliary ring element. The assemblies can by themselves adjust the radial gaps between the assemblies and the liner, and the gaps between the assemblies and the wall of the ring groove in the piston. The two ring elements engage with each other on their flat sides, and there is a notch for accommodating lubrication oil provided in the engaging portion. The radial cuts in each ring element stagger each other by an angle of 180. The two ring elements are good sealing and lubricating, respectively, therefore they can reduce the leakage of gas and the compensation of oil, and have a long period of use. They can thus improve the efficiency and the power of internal combustion engine, and reduce the emission and the noise of the internal combustion engine.

Title: Regulating the fuel pressure in an internal combustion engine
Inventor: HAMMEL CHRISTOF
IPC: F02D41/14
Filed: 1998-08-12
Abstract: Controlling a high-pressure fuel supply installation in an internal combustion engine, in particular an engine with a common fuel rail system (figure 1), comprises the steps of conveying fuel from a low-pressure region into the high-pressure region including the rail, detecting the fuel pressure P in the rail using a pressure sensor 140, and then regulating the pressure in the rail by comparing the actual pressure value with a set target value PS. Regulation is performed by a regulating valve controlled by a coil. From the comparison of the actual pressure P and the target pressure PS, a regulator 400 sets a magnitude for the formation of a drive control signal, I, for the coil. This magnitude, along with values for the conveyed fuel quantity throughput and the admetered quantity throughput is supplied to a characteristic field 410. The regulated path 436 is linearised, wherein the regulator 400 presets a required pressure build-up quantity throughput.

Title: Reducing power consumption in a telephone base station in the event of a fault
Inventor: HONDA TOSHIO
IPC: H04B1/16
Filed: 1998-12-02
Abstract: When one or more components of a cellular telephone base station have failed and resulted in the base station losing its functions, means are provided to power down components of the base station in order to avoid wasteful power consumption from the base station's mains supply, or if this has failed, from its back-up power supply. When failure occurs to a part of the base station, the part sends a failure information signal to a control section 2 in order to inform the control section of occurrence of the failure. The control section 2 judges whether or not the base station has lost its functions and if it is judged that the base station has lost its functions, the control section 2 sends a power supply interruption signal 20 to a power supply 1 of the base station. When the power supply interruption signal 20 is received, relay circuits (figs 2-4,6-8) of the power supply 1 are opened and power supply from the mains power supply and a back-up battery circuit 5 is interrupted. The interruption of power supply can alternatively or additionally be executed by reception of a power supply interruption instruction from higher level equipment, e.g. an exchange or communication device in a maintenance centre, by wired or wireless means. Thus wasteful power consumption can be stopped without sending maintenance staff to the base station.
