Title: An Axial Piston Machine
IPC: F03C1/30
Filed: 1980-11-24
Abstract: An axial piston machine comprises a piston block 12 driven by a shaft 14 and in the axial bores 21 of which pistons 22 are sealingly slidingly guided. The ends of the pistons are urged by the force of springs 23 against a tilting yoke 29. The pivot point (C) of the tilting yoke is displaced - with respect to the axis of the shaft 14 - towards the upper dead centre and is displaced-with request to the plane A - A extending through the centres of the piston ball joints 26 - in an axial direction towards the piston block 12. This means that, due to the unequal lever arms, the piston forces acting on the tilting yoke produce an automatic tilting of the tilting yoke. It was previously necessary to provide a special spring for this purpose. The resetting of the tilting yoke 29 takes place, for example, through a pressure influenced piston 31. <IMAGE>

Title: Servo-control system
IPC: A61F2/68
Filed: 1981-03-17
Abstract: A servo-control system in which a motor is used to move a member such as a prosthesis, has first and second variable transducers comprised by two inductors, two resistors or two capacitors. The first transducer is personally variable to set a desired position to which the movable member is to be moved. The second transducer is drivingly connected with the movable member so that a variable frequency is generated as the member moves. The two transducers are part of a closed-loop control circuit. Alternatively, the system can be open-loop, conditioned by the state of the control circuit, or, arranged to respond to myo-electric signals.

Title: Spring hinge
IPC: E05F1/12
Filed: 1981-07-22
Abstract: A spring hinge, for example, for mounting the flap covering the recess in which the fuel filler pipe of a motor vehicle is located, comprises a pair of hinge leaves 4 and 5 pivoting around a hinge pin 6. Movement between the open and closed positions of the hinge leaves is controlled by a spring 8 connected between the leaves in such a manner that when the leaves are adjacent to their closed position, the spring biases the leaves into the closed position, and when the leaves are adjacent to their open position the spring biases the leaves into the open position, thus serving to hold the flap, for example, in both its open and its closed position. <IMAGE>

Title: Lining pipes
IPC: F16L55/179
Filed: 1982-01-30
Abstract: A method of lining a large pipe 18 and small pipes 12 branching therefrom with a seal composition, in which the pipes are lined as connected together. Either the large pipe or the small pipes may be lined first. The portion of the seal composition forced into the small pipes when the large pipe is lined with use of a pair of pigs (22 Fig. 2A) is returned by fluid or a pig (Fig. 1C) into the large pipe again (Fig. 1B, 2C) and is subsequently applied, without being discharged from the system, to the lining layer 24 of the large pipe as a top coat with use of a second pig having a slightly smaller diameter than the first pigs. When one of the pipes has a greatly bent portion (Figs. 3-5 not shown), a pair of pigs is used wherein each pig comprises two members interconnected by a flexible linear member. The pigs may be spherical, hexagonal, elliptical or oval. The small pipes 12 are also lined by using a pair of pigs with sealing composition therebetween (Fig. 1A). <IMAGE>

Title: Apparatus for electrically measuring rotation
IPC: G01P3/483
Filed: 1982-04-05
Abstract: Apparatus for measuring the rotation of an electrically-conductive disc (especially the disc of a watthour meter) having an aperture 216 therethrough comprises a pair of plates on opposed sides of the disc. A varying voltage is applied to one of the plates 218 and the change in induced voltage on the other plate 220 as the aperture passes between. the plates is sensed by a sensing circuit 226. Two pairs of plates spaced from one another about the axis of the disc may be used to eliminate spurious pulses resulting from axial movement of the disc. The sensing circuit may be arranged to generate a signal which is passed to a signal-processor, which in turn generates a number of output signals proportional to the number of signals received from the sensing circuit. The signal-processor can be a microprocessor, which may also supply the varying voltage applied to the plate(s) adjacent the disc. <IMAGE>
Patent GB-2095202-A (GB)
Title: A drive mechanism
IPC: B66D1/74
Filed: 1980-01-31
Abstract: A drive mechanism for travel along a vertically hanging elongate flexible member such as wire rope (2) comprises a carrier (6) which supports a wheel (4) around which the rope passes. Rotation of the wheel (4) causes the mechanism to travel up and down the rope. A brake mechanism prevents the drive mechanism from running down the rope (2) when drive to the wheel (4) is interrupted. The brake mechanism comprises a ratchet wheel which is frictionally prevented from rotating relative to a shaft (31) when the shaft (31) rotates relatively to a driven gear wheel in one direction. A pawl cooperates with the ratchet wheel to permit rotation of the ratchet wheel in one direction only. <IMAGE>

Title: A method of separating <195m>Au from <195m>Hg
Inventor: COLEMAN GEORGE HUNT
IPC: G21G4/08
Filed: 1982-10-19
Abstract: <195m>Au is separated from <195m>Hg in a solution containing ions of <195m>Hg, wherein <195m>Au is generated by radioactive decay of <195m>Hg, by contacting the solution with an adsorbing agent thereby to adsorb the <195m>Hg as Hg # ions from the solution onto the adsorbing agent, and eluting <195m>Au from the adsorbing agent by means of an eluting solution. The eluting solution contains CN<-> ions as an eluting agent therefor. <195m>Au has a half-life of 30.5 seconds and decays predominantly by emission of a 262-keV gamma ray. It is therefore suitable for use in a medical isotope generator for gamma-scan studies of heart action.

Title: Gas valve
Inventor: CLOW HUGH
IPC: F16K31/06
Filed: 1983-05-19
Abstract: A gas valve 1 for a gas oven includes a conduit 8 for the passage of gas to the oven burner. The conduit 8 has a narrowing section defined by magnetic pole pieces 9 and 10, and a permanent magnet 11 is provided to generate a magnetic field across the gap between the pole pieces 9 and 10, constraining a ferrofluid 12 to prevent the passage of gas through conduit 8. To activate the valve 1, to permit passage of gas through the conduit 8, currents are passed through coils 13 and 14, which together urge the ferrofluid 12 out of the gap between pole pieces 9 and 10 and towards a pole piece 15. When the flow of currents in both coils 13 and 14 cease, the ferrofluid 12 returns to the gap between pole pieces 9 and 10. <IMAGE>

Title: Ball throwing machine
Inventor: HAMMETT JOHN
IPC: A63B47/00
Filed: 1983-07-18
Abstract: The machine has a chamber 1 containing a ball hopper area 16, from which balls are fed to breach 8 by ball feed mechanism 20, and wire guide 26. The machine is powered by compressed air from blower unit 15 forcing air into the chamber 1 and out via the breach 8 and barrel 9. A means of ball heating may be provided, (e.g. for squash balls). When a ball reaches the breach 8 it is held by gaiter 27, cutting off the airflow, and causing the pressure in the chamber 1 to rise, to a point where the gaiter 27 stretches and allows the ball to be accelerated up the barrel 9. A control circuit 28 prevents another ball from dropping into the breach 8 until the previous ball has fired. The control circuit 28 is also a means of varying the interval of fire of the ball. The arrest or release of the ball from the gaiter 27 is sensed by means of air pressure sensor 34. <IMAGE>
