Patent GB-2135490-A (GB)
Title: Gaming or amusement-with-prizes machines
Inventor: STRAKER DAVID MORGAN
IPC: G07F17/34
Filed: 1983-02-19
Abstract: A fruit machine has the feature known as "nudging". When this is available, the player may be able to press a single button which will automatically index the reels to a winning position, if that is within the compass of the number of "nudges" available. Alternatively, there may be indicators associated with each reel to show to the player which reel to index, and in which direction, in order to achieve a win, again assuming that is possible. In both cases the machine will indicate to the player the prize to be won. If more than two prizes could be won, the machine may choose the best one. There can also be a gambling feature on the number of "nudges" available. <IMAGE>
Patent GB-2120687-A (GB)
Title: Improved automatic flat bed knitting machine
Inventor: STOPPAZZINI BENITO
IPC: D04B15/68
Filed: 1983-05-13
Abstract: In this machine, each slit 3 in the needle bed has inserted in it a jack 5 provided with a first butt 6, a second butt 7 and a third butt 8. The selection of each jack 5 takes place in two stages: the first defined by selection means 11, integral with the carriage, lifting the jack by its second butt 7 to position R1; and the second defined by a fixed cam 12a, integral with the carriage 1, intercepting the third butt 8, with consequent further lifting of the jack to position R2. Once the selection has taken place, the first butt 6 is intercepted by a group 50 of fixed cams 13, 14, 15 integral with the carriage 1. Subsequently an additional fixed cam, integral with the carriage 1, operates on the third butt 8 in order to return the jack 5 to the non operative position R. <IMAGE>

Title: Energy conversion apparatus
Inventor: PEATFIELD ANTHONY MICHAEL
IPC: F03B13/14
Filed: 1983-06-11
Abstract: An apparatus for conversion of the energy of a stream of naturally moving liquid into a more readily useable form comprises a flexible or rigid container 1 into and from which a liquid (such as water) is alternately introduced and released via valves 4, 6, thereby producing flow of a gas (such as air) out of and into the container and through an adjacent turbine unit 7 linked to a generator, hydraulic pump or mechanical power takeoff. A diaphragm or other means may separate the gas and liquid. <IMAGE>
Patent GB-2124170-A (GB)
Title: Propelling locomotives
Inventor: BARWELL FREDERICK THOMAS
IPC: B61C15/04
Filed: 1983-07-05
Abstract: In order to augment the tractive effort of a locomotive, provision is made of a number of reaction members with magnets A to adhere them to a rail, and means reacting against the adhered members to apply supplemental drive force to the locomotive. In one form a piston C in a cylinder E on the locomotive acts on lugs D solid with the magnet A to provide the supplemental drive force. When the end of piston travel is reached, current to the magnet A is switched off to release it from the rail, and the hydraulic power is reversed to advance the magnet relative to the locomotive. The hydraulic pressure is then relieved, the magnet is switched on again and the cycle repeated. By having a plurality of magnets operating cyclically the locomotive may always have some piston cylinder units assisting propulsion. Mechanical systems may be used instead of hydraulics, and various arrangements using endless chains are described. The apparatus could alternatively be used as the sole propulsion means of a locomotive. <IMAGE>

Title: Collapsible pallets
Inventor: BURTON JAMES ALLEN
IPC: B65D19/38
Filed: 1983-11-19
Abstract: A collapsible pallet 10 which at each corner of its base 11 is provided with an upright for engaging a respective stanchion 24. The upright is in the form of a right-angled channel piece substantially C-shaped in horizontal cross-section which has in its two limbs 21 two pairs of slots 27, 28 for engaging pairs of projections 30, 31 in the lower end of the stanchion 24.

Title: Hydraulically operated multiple disc clutch
Inventor: FUKUCHI RENSAKU
IPC: F16D25/0638
Filed: 1984-01-11
Abstract: First and second ball check valves (40, 42) are installed on a clutch piston (14) for drawing off oil from an oil chamber for thereby preventing centrifugal force acting on oil in the oil chamber (22) from causing development of oil pressure in the oil chamber (22) when a hydraulically operated multiple disc clutch (10) should be held disengaged. The first ball check valve (40) is arranged close to the outer circumferential periphery of the clutch piston (14) and the second ball check valve (42) is arranged radially inwardly of the first ball check valve (40). The second ball check valve (42) has a larger clearance between a ball (42a) and the bore of that part of a hole (42b) in which it is accommodated than that in the first valve (40). <IMAGE>
Patent GB-2134660-A (GB)
Title: Testing fuel injectors
Inventor: NEEDHAM ARTHUR MICHAEL
IPC: F02M65/00
Filed: 1984-01-31
Abstract: A known type of fuel injector has a discharge passage (11, fig. 1) which can be closed off by a tip sealing valve (7, fig. 1), such closure causing recirculation of fuel via a return line (18, 19, 13, fig. 1) thus cooling the injector. In order to test the effectiveness of the tip sealing valve, the valve is closed, and the fuel filled injector is isolated from the supply and return lines. An attempt is made to introduce more fuel into the injector, a significant introduction of fuel suggesting that there is leakage from the injector discharge passage. Ports 22, 24 and bore 27 form part of the fuel supply line, and parts 25, 23 and bore 28 form part of the fuel return line. Isolation of the injector is achieved by movement of piston 26, which simultaneously displaces fuel from cylinder 31 into the supply line via passage 30, 32. <IMAGE>

Title: Electric cables
Inventor: WILSON IAN OSWALD
IPC: H01B3/10
Filed: 1985-02-20
Abstract: A mineral insulated cable comprises a mineral insulating powder impregnated with a methyl hydrogen polysiloxane, preferably in liquid form. The methyl hydrogen polysiloxane assists to render the powder hydrophobic, by limiting the ingress of moisture, and preventing reduction in insulation resistance on exposure to atmospheric humidity. A preferred form of mineral insulating powder is magnesia. The percentage, by weight, of the methyl hydrogen polysiloxane is preferably in the range 0.005% to 5% of the mineral insulating powder. The polysiloxane withstands higher annealing temperatures than the prior art siloxanes.

Patent GB-2186451-A (GB)
Title: Start-up circuit
Inventor: MOON PHILIP ALBERT KENNETH
IPC: G05F3/30
Filed: 1986-02-07
Abstract: A current sink circuit comprising a drive transistor (T1) with a voltage/current dividing pair of resistors (R1,R2) connected as collector load. Feedback is provided from the junction of the pair of resistors (R1,R2) to the base of the transistor (T1). The collector of this transistor is connected to the base of one or more further drive transistors (T2,.,TN) which latter act as current sinks. The value of the collector resistor R2 is selected so that the circuit exhibits a steeply peaked current-voltage characteristic, the peak corresponding to low supply voltage. This circuit thus has a characteristic suited to start-up operation. It may be used to inject or extract priming current into current circuits of the type exhibiting strong supply injection - eg. constant current source/sink circuits used in Radio Pagers and the like. <IMAGE>
