Granted: 2005-10-18
Abstract: The flow of gas between two vessels, each of which undergoes cyclic changes in gas pressure, is controlled by two check valves installed in parallel between the vessels. The first check valve allows gas to flow from the first vessel to the second vessel when the differential pressure between the vessels exceeds a first value, and the second check valve allows gas to flow from the second vessel to the first vessel when the differential pressure between the vessels exceeds a second value. The gas flow control method is particularly useful in pressure swing adsorption processes.

Abstract: A lightwave oven cooking method and apparatus using power and pulsed power applied to a plurality of high-power lamps which provide radiant energy in the electromagnetic spectrum and having wavelengths including the visible and near-visible ranges wherein irradiation is applied to the food by applying power to the lamps for a specified period of time without vaporizing all of the surface water on the food, and then applying reduced irradiation to the food to complete the cooking cycle without producing an overly browned surface which inhibits deep penetration of radiation in the near-visible and visible ranges. The reduced power can be at a reduced duty cycle which can be done in a sequence of one or more reducing steps in the duty cycle or a continuous reduction of the duty cycle of the power applied to the lamps. A change in color, in water vapor concentration emitted from the surface, in the food temperatures and/or in the generation of steam to a predetermined degree can be sensed to reduce power.

Title: Apparatus and method for rapid replacement of upper blowout preventers
Inventor: SENEVIRATNE PADMASIRI DAYA
IPC: E21B15/00
Filed: 2000-04-27
Granted: 2004-09-14
Abstract: Apparatus and method for rapid replacement of upper inside blowout presenters (IBOP) on a top drive system (TDS) utilizes a hydraulic pressure booster to increase the operating pressure of a pipe handler/torque wrench, an air amplifier to increase the air pressure to a main shaft brake of the TDS in order to provide torque back-up, a rotary table back-up structure (RTBS) for providing a torque back-up for removing the upper IBOP, and a drive ring for preventing relative rotation between the RTBS and upper IBOP. The saver sub and lower IBOP are first broken out, or loosened, with the pipe handler/torque wrench. The upper IBOP is then broken out by placing the RTBS over the rotary table with the rotary table and the TDS main shaft locked. The modified TDS and pipe handler/torque wrench are then used together with the RTBS and drive ring in order to rapidly and safely replace the upper IBOP.

Title: Three phase flat cable inductance balancer
Inventor: LAYTON JAMES E
IPC: H01F38/00
Filed: 2000-04-27
Granted: 2008-04-15
Abstract: An inductance balancer is connected between a drive and a flat three phase power transmission cable employed to carry power to a remote load. The inductance balancer includes a first inductance device (e.g., a single wound inductor) connecting the center cable conductor to the drive and raising the total effective inductance of the center cable conductor to the inductance of either of the outer cable conductors at maximum inductance. The inductance balancer also includes a second inductance device connecting both outer conductors to the drive and adding an inductance equal to that of the first inductance device when current exists only on an outer conductor and the center conductor, but adding no inductance to the outer conductors when current exists only on those two conductors. The second inductance device may be a dual wound inductor with each series connected to an outer conductor so that current carried or returned by one outer conductor travels through the inductor in an opposite direction to current carried or returned by the opposite outer conductor. The inductances resulting from equal currents on the outer conductors will therefore cancel, but the inductance resulting from currents in only one outer conductor and the center conductor will not. The result is a degree of equalization of total inductance on all conductors for all current phasings, removing the flat cable characteristics from the system.

Granted: 2005-11-15
Abstract: A laser control system is disclosed including a microprocessor, which precisely adjusts the wavelength of light ouput from the laser (118) by monitoring the transmissivity of an in-fiber Bragg grating (124) coupled to the output of the laser. The Bragg grating is fabricated to have a minimum transmissivity at the desired output wavelength of the laser. The microprocessor continually adjusts the wavelength of the laser output to obtain substantially minimal transmissivity through the grating. At which point, the laser is locked to the desired wavelength. Alternatively, the microprocessor can monitor light reflected from the grating, and continually adjust the wavelength of the laser output to lock the laser at a wavelength providing substantially maximum reflectance by the grating. Use in an optoelectronic wavelength converter.

Title: Systems and methods for producing standby uninterruptible power for ac loads using rectified ac and battery
Inventor: OUGHTON GEORGE W JR
IPC: H02J9/06
Filed: 1999-03-16
Granted: 2007-05-15
Abstract: Systems and mehtods for producing standby uninterruptible power for an AC load rectify an AC utility input voltage to produce a rectified voltage and activate a DC battery voltage in response to a change in the AC utility input voltage to thereby produce a standby DC voltage. The rectified voltage and the standby DC voltage are connected to an AC load that includes input rectification to thereby produce standby uninterruptible power without the need for costly, bulky, and/or unreliable inverters or converters. Seamless transfer of power may be provided to support the AC load upon failure of the AC utility input voltage and upon restoration of the AC utility input volt- age. The AC utility input voltage is preferably rectified by a diode rectifier, most preferably a full-wave diode rectifier including at least four diodes, to produce the rectified voltage. A diode switch is used to activate the DC voltage from the battery in response to a change in the AC utility input voltage to thereby produce the standby DC voltage. The diode switch may include a separate diode and an electronic or electromechanical switch. Alternatively, the diode switch may be a single element such as a thyristor. The diode rectifier and the diode and switch are connected in a diode-OR connection that provides thestandby uninterruptible power for the output of the UPS. The diode-OR connection allows the strongest source to support the AC load at all times.

Abstract: In accordance with the present invention, a cartridge-style heater received into a bore in an engine block is provided with a quick-release retaining member that attaches to the heater about its outer circumference. A pair of spaced legs and an arm extending from a center portion define the retaining member. The pair of legs frictionally engage the heater while permitting heater to rotate within the bore relative to the member even if the member is fixed to the engine. The rotation also permits the retaining member to rotate about the sleeve to align the retaining member to a predetermined attachment location on the engine independent of the orientation of the heater within the engine bore. This invention provides flexibility in the orientation of the heater to receive an electrical connector from an external power supply and attachment of the heater to the engine regardless of the engine configuration or vehicle model, thereby improving installation, serviceability, and use of the heater.
