Patent GB-2217380-A (GB)
Title: Vehicle door lock actuator
Inventor: WILKES STEVEN FRANK
IPC: E05B65/20
Filed: 1988-04-16
Abstract: Motorised actuator for vehicle door locks e.g. as part of a central locking system has a powered drive input element (20), a drive output element (24) movement of which locks and unlocks the lock, and a clutch element (34) operating to transmit drive to the output element but having a disengaged condition permitting independent (e.g. manual) actuation of the lock. A camming formation (28) of the input element has a formation (34) of the clutch element coacting therewith and the clutch element has another camming formation (36) engaging another coacting formation (38) of the output element. The formation are provided with acting faces (32,44,46) angled so that drive force applied from the input element through the clutch element to move the output element against reaction loading of the latter acts to urge the clutch and output elements into positive drive transmitting engagement but reaction forces translated from the output element with no drive force from the input element releases the clutch engagement by camming the latter formations out of drive transmitting engagement automatically to put the mechanical into the disengaged condition. Preferably powered movement of the input element with the mechanism in the latter condition further shifts the clutch element into a superlocked condition in which the output element is positively retained in that condition.

Patent GB-2220538-A (GB)
Title: Transmission line switch
Inventor: KING GERARD
IPC: H01P1/15
Filed: 1989-01-20
Abstract: A transmission line switch allows a single output line 3 to be switched to one of two or more input lines 1, 2 to which it is permanently connected at a common junction. Each input line has an associated amplifier stage 10 which can be biased in a normal high gain ('on') state, or in an isolation ('off') state. Suitable biasing in the 'off' state ensures that the amplifier stage output presents a low impedance to its own input line, the length L of which is chosen to reflect a high impedance at the junction 4 with the other lines. Correct design enables the return loss and insertion loss of the 'on' path to be kept to low values whilst simultaneously offering a high insertion loss to the 'off' path signals. Lower noise figures can be obtained with this circuit, depending mainly on the noise produced in the amplifier. <IMAGE>

Patent GB-2230886-A (GB)
Title: Recognition of shapes
Inventor: HOSKING KEITH HERBERT
IPC: G06V10/46
Filed: 1989-04-29
Abstract: The boundary of a shape imaged on an array is coded to simplify it and remove minor deviations in its outline by the use of a rectangular mask which is centred on one position on the boundary, e.g. P, and the position Q at which the boundary strikes the edge of the mask is noted. The portion of the boundary from P to Q is then approximated to the nearest of eight compass directions, in this case a three element displacement in an easterly direction. The mask is then centred on point Q and the procedure repeated. A coded version of the outline is produced which reduces processing when comparing with codes for reference shapes. <IMAGE>
