Patent GB-2182433-A (GB)
Title: Remote sensor
Inventor: PITT GILLIES DAVID
IPC: E21B47/06
Filed: 1985-11-02
Abstract: A remote pressure sensor includes means for temperature compensation. The sensor (11) is coupled to a remote station (12) via an optical fibre link (13) and modulates incident light with a first signal corresponding to pressure and a second signal corresponding to temperature. The remote station recovers the two signals to provide a temperature compensated pressure measurement. In the embodiment the pressure sensor (11) is of the kind including a flexible element which vibrates at a frequency representing the pressure, and thereby amplitude- or frequency-modulates the incident radiation. The sensor may be provided with a temperature-dependent layer (16) of e.g. gallium arsenide, which returns frequency-shifted light, the amount of the frequency shift representing the temperature. <IMAGE>

Title: Brazing eutectic
Inventor: TOVEY STUART JAMES
IPC: B23K1/19
Filed: 1986-03-26
Abstract: A sensor for assessing conditions within a metallic high pressure boiler 10, has a sensitive tip section 12, which is insulated from the boiler by virtue of a ceramic spacing member 101.

Title: A miniaturized dead reckoning automatic position sensor and recorder for attachment to animals
Inventor: WILSON RORY PAUL
IPC: G01P13/04
Filed: 1987-09-15
Abstract: An automatic dead reckoner for determining the movements of animals consists of a magnet G attached to a spring- mounted arm E, orientated so as to react to differential pressure caused by the medium through which the animal moves, and a miniature fluid-filled compass B surrounded by Hall generators A.

Title: Improvements in golf clubs
Inventor: MOCKRIDGE MATTHEW NEIL PATRICK
IPC: A63B53/00
Filed: 1989-04-14
Abstract: A golf club comprises a club head assembly (11) to which is connected a shaft assembly (23). There is a bend in the shaft assembly which means that the club assembly is offset from the axis of the shaft assembly. The angle of offset is chosen, together with the weight distribution and dimensions of club head and shaft assemblies, so that the assembled club has a desired "bias angle" (i.e., the angle which the club face makes with the vertical when the club is placed on a horizontal surface with the club head assembly hanging freely). The club head is made in two or more parts which are connected together, and there is a socket which is connected to both parts and has a bore for receiving the club shaft. The grooves in the face of the club head are of less depth at the toe thereof than the heel. <IMAGE>

Title: Respiratory protective apparatus
Inventor: GLYNN MICHAEL HARVEY
IPC: A62B17/04
Filed: 1989-07-19
Abstract: Respiratory protective apparatus incorporates a flexible hood 1 which encloses the head of a wearer and which has a neck seal 2 engaging the neck of the wearer and excluding noxious atmospheric gases from the space within the hood 1 and the neck seal 2. A breathing bag 3 is connected to the hood by first and second channels 5, 7 and a canister 8 of potassium superoxide is included in one of the two channels for absorbing carbon dioxide from exhaled gas and producing an equivalent quantity of oxygen. An accumulation of carbon dioxide in the gas inhaled by the wearer of the hood 1 is avoided, without the need for providing an inner half mask or a noseclip and mouthpiece, by providing a fan 14 or other air mover which withdraws gases from the hood 1 to the breathing bag 3 through one of the channels 5 and ensures that the gases pass through the canister 8 of potassium superoxide before being re-presented to the hood 1 through the other channel 7 for inhalation by the wearer of the hood 1. <IMAGE>

Title: Fire-fighting vehicle
Inventor: BRIGGS PETER SHAW
IPC: F04D15/00
Filed: 1990-10-17
Abstract: In a fire-fighting vehicle having reel stored hoses to feed with water from a high pressure outlet of a fire pump carried by the vehicle, a control system initiated from or adjacent to a driver's position of the vehicle is arranged without further intervention from the driver to make high pressure water available at the hoses. The engine speed is controlled by automatic operation of the throttle so that the pump has adequate power and priming can be performed automatically, after which a cross-over valve (eg. 35, Fig. 2) is automatically operated. The invention is said to relieve the driver of attending the vehicle fire pump and reduce the interval between arrival of the vehicle and delivery of water to the site of the fire.   <IMAGE>

Title: A method of treating and using waste products
Inventor: FORDER DAVID EDWARD
IPC: C02F11/13
Filed: 1990-10-19
Abstract: A method of treating and using waste products and to products produced thereby is described. The method comprises agitating the sewage sludge mixture and waste products with a co-agent to bind the mixture in a mixing chamber (1) having paddles (2). The mixture is fed via a controlled feed (3) to a worm pump (4) leading to the base of cyclone (5) where it is broken down into coarse particles using air from a blower fan (6). The coarse particled mixture is passed to a cyclone dryer/disinfector (7) for sterilisation by steam from an injector (8). The treated sludge mixture may be fed via a hopper (9) to an auger press (10) from which it is extruded and passed for radiation and sterilisation in a microwave oven (12) and then cut into bricketts. Alternatively, the treated sludge mixture can be passed to hopper (16) via a controlled feed (17) to plank moulds (19).
