Patent GB-2208931-A (GB)
Title: An optically driven mechanical oscillator
Inventor: NADEN JAMES MARK
IPC: G01L9/00
Filed: 1987-08-19
Abstract: An opto-mechanical oscillator eg for sensing pressure or tension uses an optical waveguide adjacent and parallel to an oscillatory element of, for instance, thin silicon. Light propagating in the waveguide produces an evanescent field in the gap between waveguide and element, so light is coupled into the element. This light then propagates in the element to a point B at which it is absorbed and generates a thermal wave which in turn produces an elastic wave which causes the point of coupling to move relative to the guide in such a way as to make the element oscillate. Thus the amount of light coupled also oscillates so the light remaining in the waveguide is intensity modulated. <IMAGE>

Patent GB-2204198-A (GB)
Title: Socket with residual current circuit breaker and test facility
Inventor: DUCKER PAUL D
IPC: H02H3/33
Filed: 1988-03-09
Abstract: A mains supply socket or adaptor having apertures T1, T2 for receiving the pins of an electrical plug, and an interlock member 20 displaceable from one position to another position in response to the insertion of the plug, further comprises a residual current circuit breaker RC1 including means for establishing an outgoing supply, and a first electrical contact engagable with a second electrical contact to form an electrical interlock inhibiting the means for establishing the outgoing supply whenever the interlock member 20 is not at a first b of its two positions a, b. The interlock test forms part of a test sequence which is followed before the supply is established. A simulated fault can be applied at a test winding 12. <IMAGE>
Patent GB-2218591-A (GB)
Title: Apparatus for sensing a person
Inventor: MIDDLETON JOHN DAVID
IPC: G01S13/56
Filed: 1988-05-14
Abstract: Pulsed Doppler radar apparatus for sensing the presence of a person is described where the radiated power is so low that interference requirements are met, whereby the carrier frequency employed may be outside the allocated channel for the apparatus. Correlation detection techniques (10) are used to recover the resultant low level echo signals. Specially modulated electromagnetic wave pulses are so phased and frequency differenced (alternately antiphased), that the equipment has a greater sensitivity to the target than it has for close up objects. The invention applies innovative modifications to Doppler radar techniques to make them suitable for this specialised task. Also discussed is a method whereby its immunity to large interfering signals can be increased. <IMAGE>
Patent GB-2223068-A (GB)
Title: Axle drive unit having two part differential casing
Inventor: CLARKE PHILIP CHARLES
IPC: F16H57/02
Filed: 1988-06-11
Abstract: An axle drive unit comprises a crown wheel (24) and pinion (25) assembly, with the crown wheel connected to a differential gearing housing outputs on an axis extending transversely of the axis of an input shaft on which the pinion is provided, has a housing comprising two parts (11, 12) joining one another at a joint face which is perpendicular to the axis (16) of the differential gearing outputs, and bearings (17 - 20) supporting the differential in the housing are located one in each housing part (10, 12). An arrangement is also discussed wherein the joint face of the housing parts is in a plane containing the differential axis and each of the bearings supporting the differential are located partly in one housing part and partly in the other housing part. <IMAGE>

Title: A holder
Inventor: CHURCH THOMAS
IPC: E04H4/00
Filed: 1988-08-23
Abstract: A holder (10) for holding an article such as a sheet of plastics material. The holder (10) comprises a support member (12) defining an elongate channel (16) which can receive a portion of the article. The holder also comprises a resilient elongate securing member (14) adapted to be received tightly in the channel, whereby when said portion of the article is received in the channel, the securing member can also be received therein to secure the article to the holder. <IMAGE>
Patent GB-2224317-A (GB)
Title: Piezoelectric actuator comprising a piston for displacing a fuel

IPC: F02M63/00
Filed: 1989-08-01
Abstract: A piezoactuator comprising a housing having a piston bore formed therein. The tip portion of a piston is slidably inserted into the cylinder bore and defines a variable volume chamber therein, and a piezoelectric element is supported between the piston and the housing. A hollow cylindrical resilient member is fitted onto the outer wall of the piston and inserted between the piston and the housing to apply a compression load to the piezoelectric element via the piston. The hollow cylindrical resilient member has a plurality of circumferentially extending slots arranged in a point of symmetry about the axis of the hollow cylindrical resilient member.

Filed: 1989-08-01
Abstract: A panel support system, comprising panels 40 and a panel support frame 42, in which each panel 40 is supported at two edges only by the support frame, thereby facilitating easy insertion and removal of the panel from the support frame. The frame may be formed of inverted T section members, and the panels have rebates to engage the flanges. Cross- members eg 85 may be provided at intervals. Space 75 is provided between upright 55 and panel 40, so that, by tilting and moving the panel towards the upright 55, the panel can be extracted without needing to provide space above the upright. <IMAGE>
Patent GB-2238617-A (GB)
Title: Detector for flammable gases
Inventor: HOLTOM RALPH
IPC: G01N27/16
Filed: 1989-11-28
Abstract: A catalytic detector element for flammable gases comprises contact areas 5, 6 on either side of a zig-zag strip-form heater 4 which is coated with catalyst pad or bead 7. Current is passed through the heater in the usual way and a flammable gas is detected by combustion in the catalytic bead 7 thus raising the temperature of the heater and changing its resistance. Prior heater coils were fragile but the heater 4 and contacts 5 and 6 are photolithographically deposited in plantinum on a layer 2 of silicon nitride (or oxide) on a silicon chip, overcoming this problem. To assist thermal isolation of the heater an air gap 9 is formed beneath the silicon nitride by etching through minute perforations which have been themselves etched in the silicon nitride layer. The bead 7 may be of alumina containing a catalyst. <IMAGE>

Title: A method of cooling beer
Inventor: HUGHES MARTIN
IPC: F28D1/06
Filed: 1989-12-04
Abstract: A cooler for a container such as a beer keg consists of an enclosure 1 which partly surrounds the container of liquid leaving a space between the container and enclosure. The cooler contains apparatus for cooling a flow of air, namely a heat exchanger 3, and a fan 2 for directing this flow of air through the vents 7 and into space between the container and the enclosure so as to cool the container. A movable cover may be provided to cover that part of the container not covered by the enclosure. A controller may also be provided to sense the temperature of the container and to regulate the cooling effect. <IMAGE>
