Patent GB-2242086-A (GB)
Title: Logic circuit device
Inventor: NAKAZATO KAZUO
IPC: H01L29/66
Filed: 1991-02-14
Abstract: A logic circuit device comprises a carrier source VCC which provides an electron carrier wavefunction e.g. signal of a given phase along a number of conductive paths (5a - 5e). Logical functions are performed in terms of phase shift of the carrier. In certain regions, the paths are arranged sufficiently close to one another to produce quantum mechanical coupling between the carrier wavefunction such that the resulting phase is a function of the coupling. By phase shifting the carriers in the paths (5a, 5d) by means of applied voltages (I1, I2) logical phase combinations can be achieved. The resulting phase on path (5f) is converted to a voltage on output (19) by comparison with reference phase from path (5e). Logical AND and INVERT functions are described. <IMAGE>

Patent GB-2252715-A (GB)
Title: Studded footwear
Inventor: COLLINS DAVID ROY
IPC: A43C15/16
Filed: 1992-03-19
Abstract: It has previously been thought desirable when providing an internally screw-threaded socket (1) for use in studded footwear to provide each socket and a complementary stud (2) with complementary screw-threads with a small helix angle and many turns in order to maximise the frictional grip between the stud (2) and socket (1). The invention provides a multi-start thread requiring at most one and a half turns (560 DEG ) to achieve full engagement. Contrary to conventional thinking such an arrangement is workable and has advantages over the known single start-threads for studded footwear. Arrangements of sockets and studs with two-start threads and retaining means (14; 16; 17 and 19) to prevent unscrewing of the studs are disclosed. <IMAGE>

IPC: G01S7/521
Filed: 1992-04-06
Abstract: There is disclosed an underwater profile detection system for monitoring the profile of an underwater target, such as a trench (11) in the seabed (10) and which comprises a set of underwater scanners (15) operable to direct acoustic signals towards the target (11) and to receive reflected signals from the target in order to monitor the profile thereof, and a remote electronic monitoring station (16) connectable via an umbilical (13) to the scanners (15) and operable to process signals received from the scanners and to derive therefrom a display on a screen (17) which is representative of the profile which is undergoing scanning. Each scanner (15) comprises a waterproof housing (18) divided into first and second compartments (19, 20), an acoustic scanning head (21) pivotally mounted on one end of the housing (18) and arranged to emit an acoustic profile detection signal towards the target (11) whose profile is to be monitored, to receive the signal reflected from the target, and to translate this into a signal which is representative of the profile of the target; an electronic processing unit mounted in the first compartment (19) and connected to the scanning head (21) so as to be able to receive the profile signal and to process the profile signal for onward transmission via the umbilical (13) to the remote electronic monitoring station (16); and a drive unit mounted in the second compartment (20) and coupled with the scanning head (21) so as to advance the head through predetermined angular increments at each of which profile detection signals are transmitted. The scanning head (21) comprises two separate substantially planar acoustic transducers (22) which are capable of issuing profile detection signals simultaneously, and which are adjustable together as a unit between different angular settings under the control of the drive unit, and which are enclosed by an acoustically transparent oil filled enclosure dome (23). <IMAGE>

Title: Seaming of containers
Inventor: HAROLD GEORGE WILFRED
IPC: B21D51/32
Filed: 1992-06-12
Abstract: A contoured seaming roll 100 for forming a peripheral seal, particularly a triple seam seal, has first 106 and second 108 seaming roll portions which define a peripheral seaming profile 107. The first and second seaming roll portions 106, 108 are mounted on a cylindrical portion of a hub 101 which is rotatably mounted on a fixed shaft 102. The first seaming roll portion 106 is, in use, fixedly secured to the hub 101. The second seaming roll portion is displaceable along the hub with respect to the first seaming roll portion 106, but is biased into engagement with the first seaming roll portion 106 by a resiliently deformable ring 112 which is in contact with the undersurface of the second seaming roll portion 108. The seaming profile of the roll can thus be altered during seaming. <IMAGE>

Patent GB-2266168-A (GB)
Title: Fuel control system and method
Inventor: YAMAKAWA TADASHI
IPC: F02D41/06
Filed: 1993-04-15
Abstract: Re-starting an engine is effected by decreasing the fuel amount to be injected into the cylinder in accordance with the temperature of the engine and the time for which the engine is stopped. The decreasing amount of the fuel is determined in dependency on whether a shut-off relay 45 is ON or OFF, whether the stopping time range is within the predetermined value, or whether or not the coolant temperature is below the set value. The coefficient of the basic fuel injection amount is corrected by referring the standard value stored in maps. Therefore, there is no over-richness of the air-fuel ratio or malfunction of spark plugs, so that the engine can be smoothly restarted in any operating conditions. <IMAGE>

Title: Power mosfet with overcurrent and over-temperature protection
Inventor: NADD BRUNO C
IPC: H03K17/08
Filed: 1994-09-09
Abstract: A trimmable shut down circuit for connection to the gate of a MOSgated device (54) has a circuit which produces an output signal which increases with temperature. This signal is fed to a comparator circuit which has a threshold which decreases with temperature. A circuit node 50 is intended to have a zero temperature coefficient achieved by the sum of the threshold voltage of a MOSFET 41 and its drain current characteristic ratio. The areas of transistors 41 - 46 are trimmed by removing one or more of transistors 42 - 46 from the circuit by means of zener diodes at pads 60 - 64. The voltage at a node 53 has a positive temperature coefficient and the threshold voltage at a MOSFET 54 has a negative coefficient so that it will be left in the off-state below a set temperature. The voltage at node 56 is then applied through a logic inverter circuit to the shutdown input terminal 35. <IMAGE>
