Title: Withdrawing or injecting optical signals in optical fibres loosely housed in tubes
Inventor: SHEN NELSON MU-CHIN
IPC: G02B6/36
Filed: 1985-01-25
Abstract: An apparatus for splicing first and second ends 32, 40 of first and second optical fibers 7, 9 loosely contained within tubes 8, 10 utilizes first and second means e.g. cylindrical mandrels 29 around which the first and second tubes are tightly wrapped causing an air gap between an outer portion of a buffer of the fibers and an inner portion of the tubes to be eliminated which allows an optical signal to be injected into the first fiber and withdrawn from the second fiber. The intensity of the withdrawn signal is detected, and first and second fiber holders which respectively hold the first and second fibers are moved relative to one another to maximize the detected signal after which ends of the first and second fibers are connected to obtain a minimum splice signal loss. <IMAGE>

Title: A method and apparatus for the heat treatment of liquid
Inventor: RAUSING HANS
IPC: A23C3/033
Filed: 1985-08-22
Abstract: The invention relates to a method for the heat treatment of a liquid and in particular the sterilization of milk, the milk being heated by passing through two heat exchangers to be introduced subsequently into a pressure zone and heated to sterilization temperature. The sterilized and warm milk is cooled instantaneously with the help of a partial quantity of previously sterilized cold milk the cooling of which has been achieved in that the previously sterilized and warm milk has been made to give off its heat content by passing through the heat exchangers thereby to preheat the milk intended for sterilization.

Title: Repairing drains and underground pipes
Inventor: BOAK JEFFREY GRAHAM
IPC: F16L55/26
Filed: 1986-02-04
Abstract: In repairing a drain or other underground pipeline, a tubular body 1 having a fluid-inflatable closed end portions 3 leading and a trailing closed end portion 2 is so positioned in the drain that the closed end portions 2,3 are on opposite sides of a fault in the wall of the drain. A tubular blending unit 4 is introduced into the drain adjacent the tubular body 1 and is interconnected by a pipe 15 to injector ports 14 in the wall of the tubular body 1 intermediate of its closed end portions. The closed end portions 2,3 are inflated by the injection of fluid under pressure to effect fluid tight seals with the wall of the drain.

Title: Fuel control system for gas turbine aeroengine overspeed
Inventor: CANTWELL HUGH FRANCIS
IPC: F01D21/02
Filed: 1986-11-26
Abstract: The fuel control system (10) aeroengine includes an overspeed limiter unit (24) operative to limit fuel flow (12) when engine speed (NH) exceeds a predetermined safe value. It is conventional for such overspeed limiters to be activated only in the event of an overspeed, so to obviate the possibility that the limiter unit (24) may fail unnoticed whilst the unit is dormant, the invention utilises the limiter unit as an active part of the fuel control system on a continuous basis. The overspeed limiter unit (24) is used to control the pressure drop ( DELTA P) across a fuel metering unit (18) as a function of engine speed (NH), except when it is actually performing its overspeed limiting task. In this way, any failure in the limiter unit (24) will be immediately apparent due to its effect on the functioning of the system. …<IMAGE>…

Patent GB-2206341-A (GB)
Title: Treatment of organically-based waste matter
Inventor: STEELE DAVID FRAME
IPC: C02F1/467
Filed: 1987-06-29
Abstract: Organically-based waste matter, particularly waste matter contaminated with toxic material such as radioactive species, is contacted with an oxidising species which decomposes the waste matter to produce, inter alia, water. Current is passed through an electrolyte such as sulphuric acid to generate a product such as persulphate which then reacts with the water generated on decomposition of the waste matter to generate more oxidising species. The oxidising species may comprise radicals such as OH DEG  or hydrogen peroxide. A nett consumption of water takes place in the decomposition, thereby keeping the volumes of waste to a minimum.

Title: Filling packaging containers
Inventor: MILLER JOHN DEREK
IPC: B67D1/08
Filed: 1987-10-08
Abstract: A machine for filling packaging containers (14) with a flowable product (18, 20), the machine comprising a control valve in the form of a plug valve (30) having a body (28) defining a bore (29) forming a frusto-conical valve seat, a plug (32) having a complementary frusto-conical surface and a valve chamber (31) for pressurised fluid formed at the wider end of the plug. The chamber communicates with the bore. The plug is axially displaceable between a first position, in which its frusto-conical surface seals against the valve seat and in which it is rotatable to control flow through the valve, and a second position, in which it is withdrawn into the chamber to provide clearance between the mating surfaces of the plug and the seat but retaining clearance between its wider end and the opposite surface of the chamber so that all the surfaces of the plug are exposed for cleaining and sterilisation.

Patent GB-2216720-A (GB)
Title: Electric switch
Inventor: MITCHAM ALAN JOHN
IPC: F41B6/00
Filed: 1989-02-17
Abstract: A short-circuiting switch for a railgun has a switching assembly (18) containing liquid metal sealed therein to provide a conductive path (30). The assembly (18) is slideable between a first position at which it short-circuits first and second conductors (12) and (14) and a second position at which it short-circuits second and third conductors (14) and (16). The motive force for moving the assembly (18) from the first to the second position is derived from electromagnetic forces generated when current flows through the path (30) between the conductors (12) and (14). The assembly passes through an intermediate position at which all three conductors are momentarily short-circuited, which reduces any tendency to arcing during the transition from the first to the second position. Thus, in the first position the switch provides a short-circuit across the DC power supply to the railgun to generate a build-up of current, whereas in the second position the switch delivers this current as a pulse through a projectile-launching armature between the rails of the railgun. <IMAGE>

Filed: 1989-11-03
Abstract: An adhesive ring assembly 10 for an ostomy bag 1 comprises a circular ring of adhesive 17 around the opening 11 of the bag and protected by two release sheets 23 and 24. The release sheets 23 and 24 are of siliconized paper and are of an annular shape. Each sheet is folded in half along its diameter so that one half releasably adheres to the adhesive 17 and the second half overlays the first half. The folded edge of one sheet 24 overlaps the folded edge of the other sheet 23. The release sheets 23 and 24 are removed by pulling the edge of each second half parallel to the ring so that they peel away from the adhesive 17 from their folded edge. <IMAGE>

Title: Amplifier with linear power output to reactive load
Inventor: PATEMAN ALAN GEOFFREY
IPC: H03F3/217
Filed: 1990-02-23
Abstract: An amplifier which drives reactive loads and in particular loudspeakers in a more efficient and effectively linear manner than previous amplifiers. An amplifier which does not clip the voltage output under conditions of normal drive or over drive from the input signal. (see fig. 9). From this amplifier an output current proportional to the input signal is produced across the load and the output voltage is seen as a result of the load's impedance and emf. This voltage being available for feedback against the incoming signal; thus scaling the output current with respect to the impedance and emf of the load. This enables linear power driving of electrically and electromechanically reactive and or linear loads. (see fig.7). An amplifier where the damping current flowing through both the devices is inversely proportional to the output current drive and that maximum damping is provided in the static position where the output impedance equals the load impedance for maximum power transfer from this position. (see fig. 8). <IMAGE>
