Patent GB-2320524-A (GB)
Title: Impeller for a regenerative turbine fuel pump
Inventor: YU DEQUAN
IPC: F04D29/22
Filed: 1997-10-02
Abstract: An impeller has a plurality of vanes 54 radially extending from core 52, each having a sidewall 60 between a leading 56 and a trailing surface 58. A plurality of partitions 62 is interposed between the vanes, thereby defining a plurality of vane grooves 64. Fluid is pumped by the vanes through the grooves and flows along a generally spiral path F1 defining a primary vortex. A relief (e.g. a chamfer or radius) is formed at the intersection between the trailing surface 58 and the sidewall 60. This relief causes the fuel flowing along the path of the primary vortex to also rotate F2 about an instantaneous axis F1 thereby defining a secondary vortex, reducing turbulence, cavitation or vapour generation within the pump. The vanes may be angled or curved in the direction of rotation to increase the strength of the secondary vortex.
Patent GB-2318880-A (GB)
Title: Liquid crystal display
Inventor: CHOI YOO JIN
IPC: C08G73/10
Filed: 1997-10-29
Abstract: A liquid crystal display in which surface alignment treatment is applied to both substrates but a pre-tilt treatment to only one of the display substrates. The pre-tilt treatment is used to create multi-domain regions which change the liquid crystal director orientation within a single display region. Optical, rubbing or oblique deposition techniques may be used to define the pre-tilt sub-domains. The liquid crystal is preferably a twisted nematic containing chiral dopants. Single domain devices exhibit anisotropic optical variations that are noticeable when viewing such displays at different angles. One advantage of this multi-domain device is that this angular degradation may be eliminated or reduced. Another advantage is that by only applying a pre-tilt treatment to one substrate the number of manufacturing steps is reduced.
Patent GB-2323247-A (GB)
Title: Facsimile communication system
Inventor: SATO SATORU
IPC: H04N1/32
Filed: 1997-12-10
Abstract: A facsimile communication system allowing facsimile machines to communicate with distant facsimile machines via regional facsimile servers at lower cost than that of traditional point to point communication between distant facsimile machines. Multiple facsimile servers are connected through a digital communication network. When a user wishes to transmit a facsimile, he sends the facsimile to a regional facsimile server at low cost. The selected facsimile server uses a previously stored database to identify a regional facsimile server near the intended destination facsimile machine. The facsimile is forwarded to the identified regional facsimile server through the digital communication network and ultimately forwarded to the destination facsimile machine. Fraud is prevented by the use of identification numbers and secret codes specifying participants in the system. Each participant has a unique identification number and each facsimile machine to which he sends images is assigned a secret number. When a participant initiates a fax, he sends both his identification number and the secret code corresponding to the intended destination. The regional facsimile server with whom the user initiates his facsimile uses the identification number and secret code to verify membership in the system and determine how to route the facsimile image to its ultimate destination.

Title: Measuring relative density of a gas
Inventor: HAMMOND PAUL STEPHEN
IPC: G01N9/24
Filed: 1998-07-17
Abstract: A method and apparatus 4 to measure the relative density of a gas, for example natural gas, in which the gas is supplied through an inlet 8 to chamber 6 and leaves through outlet 10. Using a control 16 and an ultra-sonic transducer emitter 12 and an ultra-sonic transducer receiver 14 the speed of sound in the gas corrected to standard conditions (sc) is calculated, then the control 16 operates to measure the relative density RD of the gas using the formula RD = a x SoSsc + b, where SoSsc is the speed of sound in the gas corrected to standard conditions, and a and b are constants. The measured relative density may be used as a parameter in the control of the oxygen/fuel gas ratio of a gas-fired process, eg in a kiln, a compressor or an engine, (Fig. 5).

Title: Detection of retroviral subtypes based upon envelope specific sequence
Inventor: STOYE JONATHAN PAUL
IPC: C12Q1/70
Filed: 1998-05-18
Abstract: The present invention is based upon the finding that porcine endogenous retroviruses exist in two different subtypes, which we have termed PERV-A and PERV-B. The differences are reflected in sequence divergence in the envelope genes, and these differences may be used to provide nucleic acid and antibody probes which can distinguish between the two subtypes. This allows patterns of subtype transmission between cells, particularly porcine to human cells, to be monitored.

Title: Adaptive control of laser weapons
Inventor: SEPP GUNTHER
IPC: F41H13/00
Filed: 1999-01-25
Abstract: A method for adaptive beam control of medium-energy laser weapons for attacking electro-optical sensors and windows wherein, in a measurement phase, the behaviour of the laser power 3a which is reflected back from a reflection or glint point on the target is measured by a thermal imager 12 and analysed as the illumination intensity is increased. This with other parameters which influence the thermal beam blooming effect are then used to derive by calculation 11 that laser 1 power which needs to be transmitted to produce, in an attack phase, the desired laser beam diameter or the greatest possible laser intensity at the target. Thus during the attack phase the laser need not always be operated at the maximum power, but only with the power required to achieve the required result thus saving laser primary energy.

Title: Reducing transmission power to provide secure registration within an in-home wireless netwrok
Inventor: COTTON TIMOTHY R
IPC: H04B7/005
Filed: 1999-06-30
Abstract: Method and apparatus for secure registration of an access device 604 with a base station 602, for example, for secure registration of devices such as telephones, televisions, computers, thermostats and refrigerators in an in-home wireless network, involves the base station reducing its operational power level to a lower registration power level during registration, thus ensuring secure registration for a device brought close to the base station. The access device 604 and the base station 602 each have a receiver and a transmitter transmitting at an operational power level. Once registration has been initiated, either by the base station or device, the base station switches its r.f. transmitter from a relatively high power operational state 606, to a relatively low power registration state 608, transmits a registration signal 612 to the device, receives a response 616 and then restores its power level to the operational state 618. The access device may similarly reduce its operational power level to a registration power level to transmit a registration signal (figure 7). Conventional encryption may be used and transmitter power reduction may be achieved by switching in a load (222, figure 2) during registration.

Patent GB-998998-A (GB)
IPC: D01H5/26
Filed: 1961-10-30
Abstract: 998,998. Drafting-apparatus. SKF KUGELLAGER FABRIKEN G.m.b.H. Oct. 30, 1961 [Oct. 29, 1960], No. 38772/61. Heading D1D. In drafting-apparatus of the kind where the top rolls are carried in a carrier-arm by guidearms, one of the arms is provided with an aproncage, and is mounted in the carrier arm to swing in a plane parallel to the drafting-field, and means are provided between the cage and the carrierarm, or the guide arm of the next roll in a forward direction, positively to promote restoration of the first guide-arm to the setting in which the associated roll is parallel to that of the co-operating bottom roll, or to limit or prevent displacement of the arm from that setting. In Fig. 2, adjacent guide-arms 8, 9 are mounted in a carrier arm to be capable of lateral movement and carry saddles 8<SP>1</SP>, 9<SP>1</SP> of channel section which receive the necks of twin rollers. The saddle 8<SP>1</SP> carries an apron cage 21 to which is secured a finger 22 the end of which is received between the walls of the saddle 9<SP>1</SP>. There may be a small, or no, clearance between the end of the finger and the walls of the saddle 9<SP>1</SP>. The finger 22 may be resilient to load the apron cage towards the guide 19 of the lower aron. Thus, when the carrier arm is swung upwardly to lift off the top rollers, the tendency of the arm 8 to swing to a position where its roller pair would be out of alinement with the associated lower rolls is limited to the extent that the arm 9 also tends to swing out of alinement; when the arm is lowered to working position, the roller 13 rotating faster than the apron roller, the arm 9 alines itself more quickly than the arm 8, which is thus more quickly alined than would otherwise be the case. In other forms, the finger 22, or a corresponding resilient member co-operates with a member depending from the arm 9 or with the arm itself or with the carrier arm, the side walls of the arm 9 or of the carrier arm acting as limiting stops.
