IPC: A47L9/04
Filed: 2001-12-21
Abstract: The invention provides a cleaner head 90 for a vacuum cleaner comprising a housing 92, a suction opening 100 in a face 96 of the housing 92 which is intended to face a floor surface, a suction passage 110 for conducting dirt-laden air from the suction opening 100 through the cleaner head 90 to an outlet thereof, a bleed air inlet arranged in the housing 92 and closed by a bleed valve 124 which is openable to allow air to be bled into the suction passage 100 via the bleed air inlet, wherein the bleed valve 124 is adapted to open in response to the amount of force required to move the cleaner head 90 across the floor surface irrespective of the direction of movement of the cleaner head 90.

Title: Piezoelectric inkjet printhead with a partition plate which divides a common ink chamber from nozzle chambers and includes holes which define a pump length
Inventor: SAKUMA KATSUHISA
IPC: B41J2/14
Filed: 2002-04-09
Abstract: The printhead is provided with chambers 17 defined on a piezoelectric ceramic plate 16 which communicate with nozzle openings (24,Fig.2A) at end portions in a longitudinal direction and electrodes 19 which are provided on sidewalls 18 of the chambers 17.

Title: Gas turbine engine control system
Inventor: ROWE ARTHUR LAURENCE
IPC: F02C9/20
Filed: 2002-04-12
Abstract: An apparatus and method for controlling a gas turbine 10 engine involves calculating a simple corrected compressor speed value for the engine using values of compressor speed and inlet stagnation temperature of the compressor 16. This simple corrected speed value is then adjusted to take into account the water vapour concentration at the inlet to the compressor 16. This results in a more accurate value of corrected speed for the compressor, which may be used to modulate the fuel supply 36 to a combustor 20 of the engine or to control the geometry of one or more variable compressors (54 fig. 5) in the engine.

Patent GB-2374264-A (GB)
Title: Quad pumped bus architecture and protocol
Inventor: SINGH GURBIR
IPC: G06F13/42
Filed: 2000-12-29
Abstract: A bidirectional multidrop processor bus is connected to a plurality of bus agents. Bus throughput can be increased by operating the bus in a multi pumped signaling mode in which multiple information elements are driven into a bus by a driving agent at a rate that is a multiple of the frequency of the bus clock. The driving agent also activates a strobe to identify sampling points for the information elements. Information elements for a request can be driven, for example, using a double pumped signaling mode in which two information elements are driven during one bus clock cycle. Data elements for a data line transfer can be driven, for example, using a quad pumped signaling mode in which four data elements are driven during one bus clock cycle. Multiple strobe signals can be temporarily activated in an offset or staggered arrangement to reduce the frequency of the strobe signals. Sampling symmetry can be improved by using only one type of edge (e.g., either the rising edges or the falling edges) of the strobe signals to identify the sampling points.

Title: Synchronisation of multiple radars operating within the same frequency band
Inventor: BARRICK DONALD E
IPC: G01S13/00
Filed: 2002-07-22
Abstract: The invention relates to a means for synchronisation of multiple backscatter radar users via the use of GPS timing signals and a means for allowing a mix of multiple backscatter and bistatic terminals operating simultaneously and sharing the same frequency. Clock signals are generated by a receiver 2 from time signals received 130 by a GPS antenna 1 in order to provide a high degree of timing accuracy between terminals and to control the modulation of the generated radio frequency signals. A radar state machine 5 controls timing of the transmitted and received radar signals by transmitter 11 and receiver 12. Radar transmitters are programmed so that linear frequency sweep start times are staggered in order to separate echo information from each station so that they do not interfere with each other.

Title: Bridge plug with tool passageway
Inventor: NEAL KENNETH G
IPC: E21B34/12
Filed: 2002-08-01
Abstract: A bridge plug 10 comprises a tubular housing 40 having both a central passageway 18 of sufficient diameter to allow the passage of well tools and a sealing body 70 on its exterior to engage with the well casing to seal off a section of wellbore. A valve 52 opens and closes the passageway as required. An anchor or slips assembly 80 secures the plug prior to compression of the seal by an activation unit 90. Premature sealing is prevented by latches 62 which are disabled only when they contact casing of a predetermined minimum diameter. The plug may be run and retrieved by a tool 20 with a lug 27 that engages a J-slot on the plug. Relative movement between the two is used to operate the valve and the seal. The plug may have a separate fluid bypass passageway containing a second valve, and allows intervention and survey tools to access the wellbore beyond the plug.

Title: Multi-sync display apparatus
Inventor: ARAI YUTAKA
IPC: G09G5/00
Filed: 2002-12-23
Abstract: There is provided a multi-sync type of display apparatus arranged such that when input synchronization signals Wa are within a predetermined phase difference, a pseudo synchronization signal generation apparatus formed by a frequency detection section 7 and a pseudo synchronization signal generation section 8 generates pseudo synchronization signals Wd that are synchronized with the input synchronization signals Wa, and if the input synchronization signals Wa exceed a predetermined phase difference, pseudo synchronization signals Wd that have the frequency synchronization signal directly before the input synchronization signals Wa are generated. A phase comparison section 9 compares the pseudo synchronization signals Wd and the input synchronization signals Wa, and outputs comparison result signals when the phase difference exceeds a predetermined phase difference, and if the comparison result signals continue to be output for N number of times, a signal change determination section 10 outputs a signal change determination signal. A display control section 5 controls R, G, B signals and displays image signals on a display element 6. Accordingly, it is possible to set the predetermined phase difference to a small value and increase the accuracy when identifying similar input synchronization signals, while also reducing erroneous operation by increasing the number N. This arrangement enables the display to correctly detect a change in image signal type and allow adjustment to be made in order to allow normal display to continue.

Title: Determining a parameter of a reservoir using a combination of simulated crosswell tomography and reflection tomography
Inventor: ARONSTAM PETER S
IPC: G01V1/40
Filed: 2003-10-06
Abstract: A method of determining a parameter of interest in a reservoir comprises deploying a first plurality of receivers a1-an in a first well and a second plurality of receivers bk in a second well, the first and second wells disposed either side of the reservoir. First signals generated by sources 203a, 203b, 203k at or near the surface are acquired at the first and second plurality of receivers a1-an and bk and used to simulate a crosswell survey using Fermat's principle. Additional sources 221a and receivers 223b located at the surface between the first and second wells are used to acquire reflection data from reflectors above 235 and below 205 the reservoir. Differential time-lapse tomographic analysis (eg attenuation tomography) of the simulated crosswell and reflection data acquired as described shows changes in the reservoir over time (eg fluid distribution, pressure, subsidence). The method provides improved vertical resolution.
