Patent GB-2379975-A (GB)
Title: Recycling a portion of an initial feed stream, which cools a fractionation column-top reflux process, back into the bottom of the column
Inventor: ROBERTS MARK JULIAN
IPC: F25J3/02
Filed: 2002-04-12
Abstract: In a method suitable for the separation of a pressurized hydrocarbon mixture, an overhead vapour is cooled 103, at least partially condensed, and reintroduced as reflux into the top of a fractionation column 102. This cooling is effected by further of cooling 122 a portion 120 of a two phase hydrocarbon in-feed stream 99, and/or first hydrocarbon vapour 108, reducing the pressure 101 of the further cooled hydrocarbon mixture, to provide a further cooled stream 109, and indirectly heat exchanging 103 the stream 109 with the overhead vapour, resulting in a warmed two phase hydrocarbon mixture 104. The warmed mixture 104 is then separated in a separator 124, into a liquid phase introduced 125 into the column 102, the vapour then being further warmed 122, 115, and introduced 127, into the column below a work expanded 117 cooled, in-feed stream of the hydrocarbon vapour stream 106. The method may be suitable for the recovering propane, with high methane rejection, or recovering ethane with high methane rejection. The method may reduce the vapour load in a rectification section of the distillation column 102 by introducing a warmed feed portion 127 into a lower or stripping portion of the column 102.

Title: Method of forming wiring using a dual damascene process
Inventor: KIM -GOO
IPC: H01L21/768
Filed: 2002-07-09
Abstract: A method of forming electric wiring using a dual damascene process wherein prevention of damage to a lower conductive pattern and low contact resistance may be achieved. A first insulation layer 30 having a first trench filled with a conductive material is formed on a semiconductor substrate. A first etch stop layer 32, a second insulation layer 34 and a third insulation layer 38 are sequentially formed thereon. A capping layer 40 is formed on the third insulation layer 38. A via hole 42 is formed by selectively etching the capping layer 40, third insulation layer 38 and second insulation layer 34. Then the capping layer 40 is partially etched and a polymer layer 46 is formed on the exposed first etch stop layer. A second trench is formed and the electric wiring is formed by filling a conductive material in a resulting structure. The polymer layer prevents damage to the conductive pattern by protecting the first etch stop layer.

Title: Optical gravity sensor, and its application in differential gravity detection of underground reservoirs
Inventor: ORBAN ANDRE E
IPC: G01V7/14
Filed: 2002-10-03
Abstract: The sensor (10) comprises a first mass (26) adapted to free fall when selectively released, the mass having optical elements (e.g. retroreflectors in an evacuated housing 34) adapted to change an optical path through the sensor (10) in response to movement of the mass. A beam splitter (22) is coupled to an output of the path in the sensor. One output of the beam splitter is coupled substantially optically directly to an interferometer (24), the other output of the splitter is coupled to the interferometer through an optical delay line (18). There may be a second mass (28), such that the optical elements of the two masses are coupled in optical series. The falling of the first mass (26) decreases the optical path length, while the movement of second mass (28) will increase the path length. A detection of a change in the interference pattern of interferometer is related to the value of the local gravitational acceleration, g, as well as the density of the deposition layers when the sensor is used for gravity well-logging.

Title: Metadata generation providing a quasi-unique reference value
Inventor: WILLIAMS MICHAEL JOHN
IPC: H04N7/24
Filed: 2002-10-21
Abstract: An audio/video generation apparatus comprises an audio and/or video generation device operable to generate audio and/or video material, and a metadata generation processor. The metadata generation processor is operable to generate metadata describing the content and/or attributes of the audio/video material. The metadata generation processor is operable to generate a reference value providing a quasi-unique reference to the audio/video material with a reduced amount of data than the audio/video material itself the reference value being generated from data values representing the audio/video material in accordance with a predetermined relationship. The quasi-unique reference may be stored in association with the metadata describing the audio/video material from which the quasi-unique reference was generated. Generating a quasi-unique reference from the information material provides a facility for identifying the audio/video material. In one embodiment the quasi-unique reference is a hash value. The hash value provides a quasi-unique reference, which can be efficiently searched in order to identify the audio/video material. Accordingly, metadata, which describes the content or attributes of the audio/video material, may be uniquely or quasi uniquely associated with the information material.

Title: Apparatus and method for using a surface oscillator as a downhole seismic source
Inventor: BUSSEAR TERRY R
IPC: G01V1/52
Filed: 2002-01-18
Abstract: A system and method for utilizing a surface located oscillator to generate seismic signals at a downhole location. The system includes a vibratory source for generating axial vibrational energy in a tubular string anchored in the borehole at a suitable location. The vibratory source may be operated at a predetermined frequency or may generate a swept frequency signal. The axial vibrations are transmitted through the tubular string and impart a seismic signal through the anchor to the formation. In different configurations, the system imparts broadband seismic signals into the formation. Sensors are mounted on the vibratory source and downhole anchor for monitoring the system operation. Seismic receivers are deployed on the surface, in offset wells, or in the source well. Signals from the receivers are transmitted to a control unit. The control unit utilizes the sensor and receiver signals to control the operation of the vibratory source.

Title: Differential current sensing circuit
Inventor: TAM SIMON
IPC: G11C7/06
Filed: 2003-09-03
Abstract: A current sensing circuit comprises a differential current input stage in which a current from a sensing device 14 is compared with a reference current generated by current source or dummy sensor 16. The differential current input stage is made up from matched transistors T1, T2 acting as a current mirror. A switch SW1 may be provided between nodes N1 and N2 of the current mirror to equalize the output voltages Vout2 and Vout1 when the sensing device is not in use. The difference in currents IIN and IREF is converted to a voltage difference Vout1 - Vout2, which can then be supplied to differential voltage output stage. The differential voltage output stage comprises two transistors T8, T9 configured as a current mirror which acts as a differential amplifier. The output from the differential voltage output stage may then be provided to a buffering stage. The current sensing circuit is fabricated as an integrated circuit, for example using thin film transistors (TFTs). The reference current and the current to be sensed therefore flow in the same integrated circuit and are subject to the same conditions, such as ambient temperature and ageing. The current sensing circuit may be used to detect the output of a transducer such as a pH sensor, fingerprint sensor or memory bit line sensor.

Title: Downlink telemetry system
Inventor: FINKE MICHAEL DEWAYNE
IPC: H04H60/31
Filed: 2002-02-13
Abstract: A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter (6) for generating pressure pulses, a control system (90), and a downhole receiver (21) for receiving and decoding pulses. In operation, a bypass valve (7) is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver (21). The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies. The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction. The algorithm also includes error checking for verifying that the instruction was properly received downhole.
