Patent GB-2297930-A (GB)
Title: Jet/spray nozzles
Inventor: HAISLEY JOHN JOSEPH
IPC: B05B1/26
Filed: 1995-02-20
Abstract: A jet/spray nozzle is adjustable between a jet mode and a spray mode according to the axial position of a control collar 16 mounted on the nozzle tube. A piston 21 slidable in the tube is driven forwards by fluid flowing under pressure to force a ball 29 into engagement with the collar. This permits the collar 16 to be maintained in a selected position on the tube against the bias of a spring 20 tending to return the collar to the spray mode position. However, when fluid ceases to flow in the tube the piston returns under the influence of a spring 23 to permit the ball to drop into a groove 26. This disengages the collar from the tube so that the collar is moved to the spray mode position by the spring 20.

Patent GB-2324212-A (GB)
Title: Device for detecting pulse signature of a vehicle alternator
Inventor: RYDER DAVID ANTHONY
IPC: H02J7/14
Filed: 1997-04-09
Abstract: An automatic trigger device has a pulse analyser which can identify the pulse signature which is characteristic of a vehicle's alternator when the alternator is generating electrical power. The pulse analyser can distinguish the alternator pulse signature from other pulse signatures which may be evident in the vehicle's electrical system. The pulse analyser may produce a signal which operates a relay, thereby energising a load on detecting that the alternator is generating power. The arrangement may be used to disconnect a refrigerator and an auxiliary battery in a caravan from the towing vehicle's battery when the vehicle's alternator is not generating power, thus preventing overdischarge of the vehicle's battery.

Title: Method and apparatus for joining a mouth of a tubular member to an apertured disc
Inventor: PALMER EDWARD LEWIS
IPC: B29C65/00
Filed: 1997-10-17
Abstract: Method and apparatus for making a thermoplastic join between a mouth of a tubular member and an apertured elastic disc. The method comprises a first step of drawing an elastic disc over a tapered round former 22 to cause at least a peripheral portion of the disc to form a wall of material presenting an outer surface to be joined. The mouth of the tubular member 10 is drawn over the wall of material so as to overlay and fit the said mouth to the outer surface presented by the wall of elastic disc material. The former is expanded to press the wall of elastic disc material radially outwardly against the mouth of the tubular member and heat is applied to melt thermoplastic material in a ring of contact between the outer surface of the wall of material and the mouth of the tubular member. The thermoplastic material may be melted into thermoplastic cloth bonded to the surface of the elastic disc. The method is of particular application to joining the mouth of a tubular enclosure to a disc of elastic material in the manufacture of a waterproof cover for covering a dressing or plaster cast of the limb of a patient.

Inventor: KOWAGUCHI SATOSHI
IPC: H04W88/02
Filed: 1997-12-11
Abstract: A mobile communication apparatus includes a wide area receiver and a cellular transceiver. The wide area receiver, which is operable at relatively low power, receives a selective calling signal from a wide area base station that forms a wide one-way communication area. The cellular transceiver, operable at higher power than the wide area receiver, performs two-way communication with a nearest cell base station that forms a two-way communication area. The wide area receiver is caused to operate at all times. However, when the mobile communication apparatus is outside the wide one-way communication area, the transceiver is caused to start operating.
