Title: Motor vehicle electrical isolator (emergency)
Inventor: KISSAGIZLIS PETER ALAN
IPC: B60K28/14
Filed: 1989-01-24
Abstract: A motor vehicle electrical isolator (emergency) is a unit which is fitted to any class of motor vehicle with an electrical supply for the means of starting and or operating an engine or motor. The purpose of this unit is to detect any heavy discharge or shorting out of the vehicles electrical supply in the event of a malfunction in the vehicle or in the event of an accident, rendering damage to body work or fittings, which could cause damage to the wiring circuit. This unit will respond to any electrical short and subsequently sever the electrical supply to the vehicle, minimising the risk of ignition by the electrical circuit to any volatile mixture or combustible materials. Overcurrent is detected by an inductive sensor which is coupled by an amplifier to control a solenoid switch so as to open its contacts and protect the vehicle wiring circuits. The solenoid has to be manually reset. When the starter motor is operated a signal is supplied to the amplifier to render the unit inoperative until the starter is disengaged. <IMAGE>

Title: Variable length sheet depositing conveyor
Inventor: WYER ANDREW FRANCIS
IPC: B65H29/18
Filed: 1990-06-28
Abstract: Sheet feeding apparatus for a buffer tray of a xerographic reproduction machine comprises a belt 12 for conveying sheets to the tray 6, input and output rolls 15, 16 which co-operate with the belt at the input and the output respectively of the apparatus, and an intermediate roll 18 which can co-operate with the belt at a point intermediate its length. The output roll is mounted on an end guide 17 of the buffer tray and, as a result, moves lengthwise of the belt when the end guide is moved to enable the tray to receive sheets of different lengths. If the output roll is moved from one side of the intermediate roll, remote from the input roll, to the other, it causes the intermediate roll to move to an inoperative position (in which it does not co-operate with the belt) and operates a latch to hold the intermediate roll in that position. The reverse movement of the output roll releases the latch and allows the intermediate roll to return to the position in which it co-operates with the belt. <IMAGE>

Title: Technique for achieving the full coding gain of encoded digital signals
Inventor: AMAN AHMAD K
IPC: H04Q11/04
Filed: 1990-09-27
Abstract: In e.g. a telephone local loop transmission arrangement, data is communicated from the customer promises to the central office utilizing a multi-dimensional, passband signal illustratively at 480 kb/s. The transmitted signal is encoded in a trellis code (in 114) and precoded using a generalized partial response filter (179). The received signal with "coloured" noise is processed by circuitry (150) that implements a trellis decoding in combination with nonlinear filtering. Noise "whitening" apparatus in the receiver increases the realizable coding gain by ensuring that noise at the input to the trellis decoder is white. The second coding process (precoding) in the transmitter (GPRS) and the associated non-linear signalling processing compensates for the undesirable effects of the noise-whitening apparatus, which would otherwise degrade system performance. <IMAGE>
