Title: Parallel processor array and array element
Inventor: JESSHOPE CHRISTOPHER ROGER
IPC: G06F9/32
Filed: 1987-02-10
Abstract: A processor element (PE) for a parallel processor array comprises a memory 16, ALU 14, accumulator 12 and status register 20 for status or condition flags. This register is connected to an inactivity circuit 22 (Fig. 2) which includes an inactivity latch for each flag, forming a set (24 Fig. 2). The PE has a first port coupled to bus (64 Fig. 4) for instructions from the array controller which can render a PE inactive by setting a latch unconditionally or conditionally upon the status of the corresponding flag and which can reset a latch. When any latch is set, the PE does not execute normal instructions received from the controller on a second port. Because inactivity can be controlled conditionally on all status flags it is possible to implant various program constructs (IF THEN....ELSE; DO WHILE; etc.) as simply as in assembly language for a conventional serial processor with its own program counter, even although only the controller has such a counter, and such constructs are performed selectively by the PE's. The additional hardware complexity of each PE is small. <IMAGE>

Title: Adjustment cylinder for mine roof support roof bars
Inventor: WATERMANN WILLY
IPC: E21D23/06
Filed: 1987-07-22
Abstract: A mine roof support includes a roof bar arrangement comprising a main bar (41 Fig. 2) supported by a prop and an adjustable bar (42 Fig. 2) pivotally connected to the main bar. An adjustment cylinder 44 is pivotally connected to both the main bar and the adjustable bar. The adjustment cylinder comprises a housing 1, a pair of pistons 2, 3, bores 18, 39 for the supply and discharge of pressure medium, and a pressure intensifier formed from a differential piston 27, a return valve 34, 35 operated by piston 27, and a control valve 23, 24 operated by a control piston 21. When pressure medium is supplied to bore 39 at a normal operating pressure, return valve 34, 35 is open and the pressure medium flows through bores 38, 32, 37 into chambers 31 thereby causing piston rods 4, 5 to move outwards. If pressure medium is now supplied to bore 39 at an elevated operating pressure, control valve 23, 24 opens and differential piston 26 is brought into operation thereby closing return valve 34, 35 and greatly increasing the pressure in chambers 31. Consequently, the adjustable bar (42) engages the roof with increased force. <IMAGE>

Patent GB-2216995-A (GB)
Title: Stabilised weapon system
Inventor: CARR PHILIP ERNEST
IPC: F41G5/22
Filed: 1989-02-17
Abstract: A stabilised weapon system for use on board a ship comprises a missile launcher mounted on a stabilised platform which may be controlled by gyroscopes and accelerometers fixed either to the hull of the ship or to the platform itself. A radar, infra-red or similar target sensing system is mounted on the same platform as the missile launcher and produces signals indicative of target position. These are compensated for ship movement, detected by the same or further gyroscopes, and the target location used to control the missile launcher. The provision of a combination of sensor and launcher on the same stabilised platform avoids disparity errors between the two systems, provides considerable saving of space on what is likely to be a crowded deck, and minimises or eliminates the need for transformation of co-ordinates between the two systems. <IMAGE>

Title: Switched reluctance motor having near-saturated magnetic core section
Inventor: ASPDEN HAROLD
IPC: H02K29/00
Filed: 1989-08-09
Abstract: A reluctance motor is powered by a commutated A.C. voltage supply which comprises full cycles of the A.C. waveform interspersed by periods of zero power of fixed duration measured in full cycles. Motor structures are described which combine, with the above method of excitation, a feature by which a portion of the magnetic circuit carrying the magnetic flux developing reluctance drive torque during the power-on periods is magnetized cyclically over a range above the knee of the applicable B-H curve to obtain a non-saturated condition. A closed circuital flux path 20, 24 through this portion, separate from the flux route through the stator poles 22, is magnetized by permanent magnets 25 or electro magnet means to secure this near-saturation condition in which thermodynamic adiabatic cooling processes operate to enhance the power conversion efficiency of the motor by virtue of domain flux rotation processes. <IMAGE>

Title: Turntables
Inventor: CLENTON DAVID JOHN
IPC: B60S13/02
Filed: 1989-08-15
Abstract: A turntable for a motor vehicle comprises a rotatable disc (1) adapted to support a motor vehicle, the disc (1) being mounted by a sprung spigot (15) which allows movement of the disc (1) between an inoperative position in which the disc cannot rotate and an operative position. A biassing spring (3) urges the spigot (15), and hence the disc (1), to the inoperative position in which a rubber pad (23) engages with an inner flange (11) to act as a friction brake to prevent rotation of the disc. When a vehicle is driven onto the disc it overcomes the spring (3) and moves the disc (1) down to its operative position in which the disc can rotate. The turntable will only rotate when it is heavily loaded and will not rotate when loaded by the weight of a normal person. <IMAGE>

Patent GB-2235315-A (GB)
Title: Digital signal processing
Inventor: LIND LARRY FREDERICK
IPC: G06F17/17
Filed: 1990-08-09
Abstract: A sequence of N sine and/or cosine values, e.g. for Fourier Transforms, quadrature demodulation or test tone generation, is produced by interpolation from a geometrically-spaced table of initial sine values using a first interpolation formula. After being output, each sine value is replaced in the table by a further calculated value, so the sine table size is kept at M = (Log2N)+2 (where N is the number of sine values in the sequence). To avoid round-off errors at widely-spaced interpolations, a second interpolation formula is selectively used in which sine values are interpolated from cosine values. A cosine table is therefore maintained concurrently with the sine table.

Title: Locks
Inventor: JOHNS-HUNT JOHN
IPC: E05B21/00
Filed: 1991-02-26
Abstract: A lock includes a pack of levers 5 (i.e. pivoted/slidable tumblers/detainers) and an acid-responsive relocker comprising a bar 15 pivoted in the upper part of the casing 1 and normally supported by a spring-metal strip 17. The strip 17 is of e.g. phosphor bronze and has a bend 20 seated in a drain hole 21 in the bottom of the casing 1. In the event of acid being poured or sprayed into the keyhole in an attempt to dissolve the levers 5 the acid will flow over the strip 17 in the region of the bend 20 and disintegrate the same before the levers are significantly weakened, thus allowing the relocker bar 15 to fall and apply an additional blockage to retraction of the bolt 3. The bar 15, being located in the upper part of the casing, is itself unlikely to be contacted by the acid and can maintain the lock in a secure condition notwithstanding eventual destruction of the levers. <IMAGE>
