Patent GB-2324912-A (GB)
Title: Beam forming network
Inventor: MUUOZ-GARCIA SAMUEL
IPC: H01Q1/28
Filed: 1994-04-18
Abstract: A multiple-beam forming network comprises a first set 30a of passive power divider networks e.g. Butler matrices 50 having equal numbers of inputs and outputs N 1  (fig.4 not shown). The outputs are connected orthogonally to a second set 30b of power dividers 50 with a different number of inputs and outputs N 2 , that is each respective output from one divider in the first set 30a is connected to a different one of the dividers in the second set 30b. The total number of matrices in the two sets is less than N 1  + N 2 . that is each set has fewer dividers than inputs. A number of beams less than N 1 <SP>2</SP> are connected to inputs of the first set and outputs of the second set are connected to an array of less than N 2 <SP>2</SP> elements of an antenna array. The arrangement allows fewer splitters to be used than a normal square array, which reduces overall power consumption and weight. This is advantageous in satellite mounted systems for mobile communications. The invention may be used to supply the hexagonal antenna array of GB2288913.

Title: Adaptive phased array antenna with weight memory
Inventor: LIM KYU-TAE
IPC: H04B1/40
Filed: 1998-08-04
Abstract: An adaptive phased array antenna system consists of an array of antenna elements 510 connected to a power feeder unit 520, which, according to a set of weights, adjusts the amplitude and phase of a signal received by or transmitted to the antenna elements. The power feeder unit is connected via power combiner 540 and amplitude detector 550 units to a receiver unit 570 and/or via a power divider unit 530 to a transmitter unit 560. A beam control unit 590 receives a sample of the combined received signal and instructs a weight memory unit 580 to supply a set of weights to the power feeder unit to set or adjust the beam directivity of the array. This can allow the antenna system to seek an optimum antenna directivity.

Title: Vehicle braking distance warning system incorporating assessment of driver
Inventor: BARROW NICHOLAS FRANCIS
IPC: G01S13/931
Filed: 1998-08-14
Abstract: A safe braking distance warning system and method is disclosed comprising means, eg by radar emitting unit 40, for determining the distance from a first vehicle being operated by the user to a second preceding vehicle in the direction of travel. The system further comprises means to assess the status of the driver and to continually correlate the speed of the users vehicle, as determined by sensor 50, and the status of the driver, as determined by moistness of hands or pupil dilation, to calculate a safe braking distance, and correlate the safe braking distance with the distance to the preceding vehicle to activate an alarm if the safe braking distance is greater than the actual distance determined. There is further disclosed a method to take account, in the distance calculation, of the driver reactions determined while the vehicle is stationary, and further to disallow movement of the vehicle if the driver reactions are unacceptable.

Title: Surge-proof irrigation system controller
Inventor: CARTER JAMES A
IPC: H02H9/00
Filed: 1998-12-11
Abstract: The electronic control unit comprises a timer unit for providing system control signals in response to input data and a driver unit connected, via cables, to devices to be controlled, e.g. irrigation valves in an irrigation system. The timer unit and the driver unit are physically separated by an air gap and communicate only via a wireless link e.g. infrared. The sensitive electronics contained within the timer unit are thus protected against electrical surges occurring in the field wiring or driving part of the system. Surge suppression components are included in the drive unit circuit.

Title: Ink leakage control arrangement for ink cartridge using spring-loaded bag(s) to receive any leakage via a surge tube
Inventor: KOMPLIN STEVEN ROBERT
IPC: B41J2/175
Filed: 1998-12-14
Abstract: A sealed reservoir 11 (Fig.1) of an ink cartridge includes at least one spring-loaded bag 21 (Fig.1) which acts as an accumulator to control back pressure within the reservoir. A vent 17 (Fig.1) provides ambient air for the bag(s) and serves as an air source for a bubble generator 37 (Fig.3). The interior of the bag(s) communicates with the bubble generator via a surge tube 23 so that air is supplied to the bubble generator when bubbles are required within the reservoir to decrease back pressure therein. The tube permits the interior of the bag(s) to receive any ink that leaks from the sealed reservoir which passes through at least one capillary channel 40 (Fig.3) of the bubble generator when the reservoir back pressure decreases below a specified value.

Title: Interlock mechanism for slidable units
Inventor: BOOTY ALAN
IPC: E05B65/464
Filed: 1995-06-30
Abstract: A unit 1 such as a filing cabinet has an interlock mechanism 5 for preventing more than a fixed number of slidable members 3 being slid with respect to a frame at a time. A plurality of vertically mounted rod members 6a, b, c are mounted so that they are vertically movable but restrained from rotation. For each slidable member 3 a cam piece 17 is mounted for rotation and for vertical movement. Means 9 on each slidable member 3 cause rotation of the cam piece 17. The rod members 6a, b, c and cam piece 17 define a continuous stack, each cam piece 17 being mounted, on a link pin 18, between the two rod members 6a, b, c in abutting relationship therewith. Cooperating cam surfaces 14 are provided on the cam piece 17 and on the rod member 6a, b, c abutting the cam piece 17 for causing vertical displacement when the cam piece 17 is rotated to thereby cause extension of the length of the stack. Stop members 8 are arranged on the frame for limiting the length so that when the fixed number of slidable members 3 have been slid, further rotation of the cam pieces 17 and extension of the stack is prevented, so that no further slidable members 3 can be withdrawn.

Title: Liquid fuel combustor
Inventor: KONAKAWA KATSUZO
IPC: F23D11/02
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a carburetor by making the air heated by the carburetor to quickly vaporize liquid fuel into a gas by accelerating the vaporization of the fuel by mixing air in the liquid fuel in the carburetor. SOLUTION: Since a combustor is constituted in such a way that a fuel supplying means 32 and an air supplying means 34 are communicated with a carburetor 1, and liquid fuel and air are supplied to a heated vaporizing chamber 26; the combustion amount adjusting range for good combustion can be widened by adjusting the amount of primary air for combustion to the optimum value by adjusting the speed of a mixed gas blown from a nozzle section 23. In addition, the size of the carburetor 1 can be reduced by accelerating the vaporization of the fuel by mixing air in the fuel in the carburetor 26. Therefore, the deposition of tar in the vaporizing chamber 26 can be suppressed when quality-changed oil, etc., is used, because the flow velocity of the mixed gas increases and the staying time of the mixed gas in the chamber 26 becomes shorter.

Title: Bonding method of thin sheet
Inventor: MINAMI SHIYUUBIN
IPC: H01L21/301
Filed: 1991-01-30
Abstract: PURPOSE:To bond a thin sheet such as a silicon wafer or the like to a holding member or the like for polishing use with good accuracy. CONSTITUTION:An adhesive layer 5 is formed on a bonding face for a wafer 4; then, the wafer 4 and a holding member 3 are brought face to face via the adhesive layer 5. At this time, the temperature of the holding member 3 is set near the melting point of the adhesive layer 5. In addition, they are pressurized, and the surface of the adhesive layer 5 is pressure-bonded firmly to a holding face 3a for the holding member 3. The holding member 3 is heated to a temperature which is higher than the melting point of the adhesive layer 5; the adhesive layer 5 is melted after that, the holding member 3 is cooled; the adhesive layer 5 is hardened again. At a stage where the adhesive layer 5 is pressurized, the temperature of the holding member 3 is kept near its melting point. As a result, the adhesive layer 5 does not flow, and the parallelism of the wafer 4 with the holding member 3 can be kept with good accuracy.
