Patent GB-2105071-A (GB)
Title: Control of device acting on a moving web
Inventor: ANDREW DAVID FRANCIS
IPC: B23D36/00
Filed: 1981-08-21
Abstract: The device is driven repeatedly through its operating motion at a speed such that the time interval between successive performances of the operation, and hence their distance interval on the moving length of material, can be controlled whilst ensuring that the speed of the device during performance of the operation is matched to that of the length of material. Amplifier (A) controlling the drive motor (M) receives a first signal (Vr) indicative of the required motor speed, which is related to that of the web, and a second signal, a quantity of charge stored on capacitor C2, which accelerates or decelerates the motor to give the required time between operations. <IMAGE>
Patent GB-2087176-A (GB)
Title: Generator shorted diode protection system
IPC: H02K11/00
Filed: 1981-10-13
Abstract: A shorted diode protection system for a brushless alternating current generator of the type having an energizeable exciter field winding 36 includes a circuit arrangement 55 for sensing the voltage differential across the exciter field and pairing the voltage differential with generator load current measured at 26 to provide an output signal that falls within a predictable range of values over a normal generator load current range. The output signal is of such a nature that it falls within a higher range of values upon the occurrence of a shorted diode. Another circuit arrangement 65 is responsive to the output signal such that whenever the output signal exceeds a preset value over the normal load current range, an output is generated that operates to cause the interruption of the exciter field. <IMAGE>

Title: Reinforcement for concrete joints
Inventor: CLAPSON JOHN DAVID
IPC: E04B1/04
Filed: 1982-04-26
Abstract: The invention relates to a package of reinforcement members and the use thereof in making a structural joint between two cast concrete components. The package comprises a base unit 6 and one or a plurality of first reinforcement members 2 which extend thereinto.

Title: Tooth forming tool for splining tubular elements
Inventor: CARENE NICHOLAS J
IPC: B21D17/02
Filed: 1983-02-04
Abstract: A tool 12 for pressure forming teeth in the periphery of a cylindrical tubular workpiece (16) by rolling has a working surface which improves the flow characteristics of the workpiece during the tooth-forming operation. Flow characteristics are particularly improved during initial contact of the tool with the workpiece (16) by providing an initial toothless clamping section on the tool preceding the first toothed working section. The clamping section minimizes or eliminates radial workpiece separation from a mandrel (94) ahead of the toothed section during the initial stage of the tooth-forming operation, which separation is manifested as a wave or buckling effect in the workpiece during initial forming and as an out-of-round condition in the final product. <IMAGE>

Title: Heat Storage Blocks and Manufacture Thereof
Inventor: HERRELL DEREK
IPC: C04B35/63
Filed: 1983-04-11
Abstract: A heat storage block is manufactured from a heat retention material such as iron oxide or olivine by bonding with a bonding agent curing at a low temperature such as a phosphate bonding material e.g. sodium hexametaphosphate.

Inventor: DUNCOMBE EDWARD
IPC: G01D5/20
Filed: 1983-12-16
Abstract: A transducer for use in hostile environments has an externally threaded rod (13) slidable in an internally threaded tube (10).

Title: Firing lock with safety system for self-loading firearms
Inventor: SMITH DAVID EDWARD
IPC: F41A17/74
Filed: 1984-03-22
Abstract: A safety catch for a self-loading pistol type firearm is provided with a safety catch comprising an arbor (HH) rotatable in the firearm frame (A) by means of manual levers (HH2 and JJ2) mounted outside the frame on either side. From a rest or off position, in which the firearm can be fired, the arbor can be rotated upwardly to an end position in which means on the arbor engage the hammer (J) when it is in either the cocked or uncocked position, to lock it against rotation and thus prevent the firearm being fired. Additionally, when the hammer is cocked, the arbor can be rotated in the opposite direction, in which case it causes rotation of a detent member (LL) which lifts the ejector (L) to engage and hold the firing pin (S) and to retract the striking end (S2) of the firing pin within the slide (B) and thereafter to trip the sear (K) to release the hammer (J) safely from the cocked to the uncocked position. <IMAGE>
