Title: Attenuation valve for the clutch of the power take-off shaft of a tractor
Inventor: VAINIOMAKI TAPIO
IPC: F16D48/02
Filed: 1985-05-21
Abstract: The valve is fitted in the pressure pipe passing from a hydraulic pump operated by the tractor engine to a clutch of the power take-off shaft to avoid shock on clutch engagement. The valve is provided with an inlet opening (A), an outlet opening (B), which are in direct connection with each other, and a leakage opening (C), which communicates with the inlet and outlet openings (A and B) of the attenuation valve via a bleed valve (20) placed inside the body (10) of the attenuation valve (4). The bleed valve (20) automatically regulates the ratio of the flows passing through the outlet opening (B) of the attenuation valve (4) and through the leakage opening (C) as well as the pressure of the flow passing from the outlet opening (B) to the clutch (5), and thereby the engagement time of the power take off shaft (9). The valve also contains a choke channel (11) in which a floating piston (12) is located with clearance to provide throttled flow into an annular space (14) to act on a piston (16) influencing the opening of bleed valve (20). <IMAGE>

Title: Clock signal selection and security arrangements
Inventor: MELINN FRANCIS
IPC: H04L7/02
Filed: 1985-08-09
Abstract: In a clock signal security arrangement three levels of master clock input signals and three levels of frame synchronisation signals are received. A respective two out of three majority decision is made for each of the master clock and frame synchronisation and is used to check the validity of the three input levels. Dependant upon the validity determination either the first or the second input clock signal is output as the master clock signal. The respective majority decision clock is output as the frame synchronisation signal. Faults detected in either of the clock sets result in an interrupt alarm signal being forwarded to a control computer of a connected telecommunications exchange together with a data word identifying the faulty input signal.

Title: Cable ladder system
Inventor: WHITE RONALD LESLIE ALBERT
IPC: H02G3/06
Filed: 1985-09-10
Abstract: A kit of parts for assembling a cable ladder system comprises straight cable ladder sections and a group of component parts (Fig. 1) differing from one another from selected component parts of which group can be assembled a plurality of multi-purpose couplings (Fig. 3 to 9) of at least two forms which differ from one another.

Patent GB-2174247-A (GB)
Title: Superconducting coil
Inventor: WILSON MARTIN NORMAN
IPC: H01F6/06
Filed: 1986-03-19
Abstract: A superconducting solenoid magnet has a shorted secondary winding 12 positioned on the opposing side of support shell 11 from a coil 10, the secondary winding is coupled magnetically to the coil and current is induced in the secondary winding at the onset of quench. The secondary winding heats up uniformly along its length when current is induced in it and in turn this heats the coil all along its length thus propagating quench in the whole coil and preventing localised excessive temperatures in the coil. The secondary winding may be hoops, a cylinder, or a shorted spiral coil. The secondary winding 12 is positioned on the opposing side (either inside or outside) of the support shell 11 from the coil 10 and is thus shielded from, and does not interfere with, alternating current tests for shorted turns in the coil. <IMAGE>

Title: Maintenance of low temperature refrigerators
Inventor: STRASSER WILHELM
IPC: F25B9/14
Filed: 1987-10-19
Abstract: A low temperature refrigerator 1 comprises a divided housing the parts 2, (3) of which are separable from each other so that, after separation, the interior space of the refrigerator 1 is accessible, to enable maintenance work on components (6, 7, 16, 18) located in the housing to be carried out, after which the housing is closed and finally scavenged with working gas. In order that after opening of the housing condensation on the cold areas of the interior space of the refrigerator is prevented, it is proposed that the areas of the refrigerator housing 2 in danger from condensation be heated locally to a temperature which is so selected that up to the completion of the maintenance work by the scavenging process this temperature does not drop below the dew point of condensable gases, such as by blowing hot air or gas into the housing to warm the said areas (as shown) or by heating said areas directly using locally fitted electric heaters (Fig. 4).

Filed: 1988-01-28
Abstract: A gas meter of the kind having one or more chambers in which a flexible diaphragm is moved back-and-forth has an oscillating flag rod (12) driving a gear box (13). A magnet-carrying disc (16) is rotated by gearbox (13) to open and close an adjacent reed switch (15). Electrical pulses produced by the closing of the switch are applied to correction box (19).

Title: Pyrotechnic train
Inventor: ALLFORD FREDERICK GEORGE
IPC: C06C5/00
Filed: 1989-08-29
Abstract: A pyrotechnic train is formed from a reactive laminate of thin films of an electron acceptor material 9, e.g. lead oxide, and an electron donor material e.g. titanium, 10, alternately vapour deposited upon a substrate 1. Selective etching or selective masking techniques are used to leave a desired network of reaction progression paths 2 for a sealed delay train or track plate for ignition. The thickness of the films is of substantially molecular order to maximise molecular intermingling between them. Ignition of the conjoint films at any selected location initiates a self-sustaining exothermic reaction which progresses laterally along the film interfaces, and may be modulated by one or more layers 11, e.g. silicon. The reactive laminate is also applicable as a heat radiation emitter, and as a bridge igniter for a detonator in place of a conventional exploding bridge wire between electrodes. <IMAGE>
