Patent GB-2121532-A (GB)
Title: Fibre optic gyroscope
Inventor: BONE MICHAEL CHRISTOPHER
IPC: G02B6/30
Filed: 1982-05-25
Abstract: A high performance single mode, single polarization fibre-optic gyroscope includes in an integrated optics architecture 26 a polarizer 20. To negate the effect of residual birefringence in the fibre 10, and external environmental changes, which result in fading of the signal at the output of the detector 17, there is included an active polarization controller 21. This controller is implemented in the integrated optics as a variable TE/TM phase shifter 22 in series with a TE<==>TM converter 23. Control signals derived from the photodetector 17 via a feedback loop 24 and electronics 25 periodically adjust the phase shifter control voltage V1, and the converter control voltage V2 to obtain maximum output from the photodetector. <IMAGE>

Title: Radar decoys
Inventor: FURZE EDWARD DAVID
IPC: F41J2/00
Filed: 1982-05-28
Abstract: Defence against radar guided missiles such as the Exocet missile is provided by metal-coated decoy balloons deployed by means of any available missile system, the balloon package which replaces the explosive charge of the missile comprising balloon ejection and inflation means. A proposed tactic is the deployment of decoy balloons in an inverted letter 'V' formation, and anchored ships may be protected on all sides by the deployment of a star pattern formation. Alternative decoy means may take the form of a cloud of metal particles or a spray of liquid metal such as mercury.

Title: Dispensing of carbonated beverages
IPC: B67D1/10
Filed: 1982-06-11
Abstract: Apparatus for dispensing carbonated beverages comprises a carbonating vessel (13) to which liquid is supplied for storage and subsequent use. The liquid supply comprises a storage tank (11) which has inlet and outlet compartments with a liquid flow connection therebetween.

Title: Obstacle detection; vehicle parking aid
Inventor: MAGORI VALENTIN
IPC: G01S17/931
Filed: 1983-11-30
Abstract: In a manoeuvring aid for road vehicles, which detects obstacles in the region near behind the vehicle 13 when its reversing, transmitter units 14, 16 and receiver units 17, 18, each of which comprises several transmitter elements or receiver elements respectively, the radiating angle  phi i and receiver angle  eta j of which are arranged in fan shapes which overlap behind the vehicle, are at the rear corners of the vehicle 13. The transmitter elements 14/1 to 14/7, 16/1 to 16/7 are activated consecutively, whereas the receiver elements 17/1 to 17/7, 18/1 to 18/7 all receive simultaneously. The direction of transmission of the radiation is determined by the time of reception of echoes from the obstacle, and the direction of reception by the receiver element that is activated by the radiation. Simple trigonometry then gives the obstacle range. The embodiment described uses infrared radiation, although ultrasonic radiation is also stated to be usable. In place of several receiver elements, a single scanning element may be used. <IMAGE>

Title: Purifying mixed-cation electrolyte
Inventor: GOODRIDGE FRANCIS
IPC: C25C1/12
Filed: 1984-08-06
Abstract: An electrolyte containing 65 g/l zinc and 150 g/l Cu is purified in zinc, that is, the copper is removed, by causing the electrolyte to fluidize a bed 8 of 1/2 mm copper particles. The bed is fluidized by 25% to make it 42 cm deep. An anode 11 is disposed above the top of the bed. A cathode 9 is disposed part-way up the bed. Copper is electroplated onto the bed particles. Any zinc which may be electroplated onto the bed particles tends to redissolve with concomitant cementation, on the particles, of copper, which can be recovered. The electrolyte is thus eventually completely stripped of copper and can be used for zinc electrowinning.

Title: Force monitoring systems for moving objects
Inventor: SHINGLER ROGER
IPC: G07C3/00
Filed: 1987-02-24
Abstract: In assembly load monitoring it is known to provide a mute or inhibit circuit which is triggered by a switch arranged to be operated just prior to a component meeting a stop, so that the loads produced on meeting the stop are ignored by a load monitoring system, but the adjustment of the switch position is troublesome. We monitor load but also look at the speed of the component during assembly, and we use the speed curve to enable parts of the load curve, associated with the abutting with the stop, to be disregarded. We can look for a predetermined deceleration or zero speed of the component as the basis for identifying the useful part of the force curve. The system can be used to measure forces required to engage and disengage gears of a gearbox.
