Title: Alternating current potential drop crack detection
Inventor: JOLLEY GRAHAM
IPC: G01N27/20
Filed: 1985-06-14
Abstract: An alternating current potential drop (ACPD) system for detecting and measuring cracks on the surfaces of electrically conducting materials (10) comprises a constant current AC generator 9 for applying current to material (10), a receiving unit 8 and a self-contained potential drop (PD) transducer unit 7 for attaching directly onto material surface 13.

Title: Compensating for camera movement
Inventor: BUSBY PETER WILLIAM
IPC: H04N5/3725
Filed: 1985-07-16
Abstract: TV cameras can reproduce an image of a viewed scene accurately provided the camera is rigidly mounted or is mounted on a stabilised platform to keep it steady. It is possible to remove image perturbations, due to camera movement, from a solid state TV camera picture by using accelerometers to measure camera movement and then using signals indicative of the movement to modify the read-out pulses of the vertical shift registers 3 and the horizontal read-out register 4 in frame Transfer CCD ie advancing or retarding the pulses 20, 21, to compensate for movement in two orthogonal directions. Interline transfer or XY CCDs may be compensated for movement in a similar manner (fig. 4). The integration time of the CCD is preferably short (eg 1 ms) to avoid blurring due to movement. <IMAGE>

Patent GB-2205686-A (GB)
Title: Circuit breaker
Inventor: PICKERING IAN JACK
IPC: H01R13/713
Filed: 1987-06-11
Abstract: A circuit breaker for opening the circuit to an electrical socket comprises a relay (6) having an armature (10), carrying contact arms (12) which are engageable with contacts (14). A tripping mechanism is operative normally to retain the armature in an operative position but in the event a current overload and/or defection of residual current, it permits the armature to be moved by a spring 16 to an inoperative position. When the relay is closed pivotable movement of a latch member (18) under the action of a spring (20) is prevented by abutment of the latch member with the armature, but on opening of the relay, and movement of the armature (10) to its inoperative position, the latch member (18) moves across the armature (10) to prevent it reclosing. The latch member (18) is reset by removing the plug from the socket to cause a shutter (24) to be moved by a spring and to cam the latch member (18) back to its inoperative position where it is retained by the shutter (24). In this manner if the relay trips and is then subjected to an inpact whilst a plug is in the socket, there is no possibility of momentary application of power to the plug. <IMAGE>

Title: Electric liquid-heating assembly
Inventor: HUNT ANDREW
IPC: A47J27/21
Filed: 1988-02-09
Abstract: In order to increase the initial rate of heating of the backplate (12) upon dry operation of the relevant appliance, the element (20) is so configured that, intermediate its ends, at least two separate portions (22, 24) thereof are in direct (or indirect) heat transfer relationship with the backplate (12). Consequently, the time taken for the primary cut-out, e.g. bimetal (18), to trip is reduced compared to a conventional element wherein only a single central portion of the element is connected to the backplate. This, in turn, means that the further temperature rise, after cut-out, is less steep than hitherto with reduced risk of deterioration of components and/or "nuisance" tripping of an irreversible secondary cut-out at an elevated temperature. <IMAGE>
