Patent GB-2135659-A (GB)
Title: Banknote dispensing
Inventor: PETTET RONALD SIDNEY
IPC: G07D7/12
Filed: 1983-02-24
Abstract: In the issuing of banknotes to customers from loaded cassettes in a cash dispensing machine, to improve security and to provide a better check on misfeeds, when the cassettes are loaded, each note is sensed for a predetermined characteristic (for example opacity or serial number) and the corresponding electric signal is retained in a storage device (28). When the cassette is loaded into a cash dispensing machine, the storage device (28) is loaded with it. As each note is extracted from the cassette, it is sensed for the same characteristic and the resulting electric signal is applied to a comparator with a signal derived from the storage device (28) for a note in the corresponding position in the cassette. If the comparison is satisfactory, the notes are issued. <IMAGE>

IPC: H04N9/24
Filed: 1983-05-16
Abstract: In a beam indexing colour CRT in which an electron beam scans light-emitting stripes (R, G, B) in the direction of their lengths, the beam indexing signal is derived from an electrode array (5, 7) arranged so that along its length some or all of the stripes straddle a respective gap between a pair of electrodes (5 and 7) of the array. The electrode array, suitably comprises two interdigitated electrodes (5 and 7). A display system utilising the CRT is also described in which inequality of beam currents returning through each electrode provides a steering signal to the transverse deflecting means. <IMAGE>
Patent GB-2140232-A (GB)
Title: Frequency synthesisers
Inventor: WELLS JOHN NORMAN
IPC: H03L7/18
Filed: 1983-05-17
Abstract: A frequency synthesiser produces a variable frequency output using a controllable oscillator and a variable frequency divider which form part of a phase locked loop. The integer division ratio of the divider can be altered during a division cycleto simulate a fractional divisor value. The phase noise or jitter which is caused by the step change in divisor value is removed by altering the divisor value in accordance with the terms of a plurality of sequences, each of which sums to zero and which represents successive rows in a Pascal's triangle. A cascaded sequence of accumulators is used to determine the starting instants of each sequence, and the length of each sequence is dependent on the number of delay lines used. Although only four accumulators are illustrated, more can be added to give any desired degree of phase noise cancellation.

Multi-stage arrangements are illustrated in Figs. 2 and 3 (not shown). The control gates may be rotary sliding vane pump/motor units or gear or roots type, or reciprocating pump/motor units or shuttle valves. <IMAGE>

Title: Detecting ships using anti-chaff radar
Inventor: BRUNET GASTON
IPC: G01S7/02
Filed: 1983-06-23
Abstract: In a system for detecting ships at sea using a radar emitting waves polarised in a given direction (V), the energy received is detected in the same polarisation plane and in an orthogonal polarisation plane (H). Only those echoes whose degree of depolarisation, relative to the emitted waves, is within a predetermined range (N1, N2) are singled out as characteristic of the presence of ships. Preferably, the procedure is carried out with a radar possessing a frequency-agile emitter (24). The echoes are then distinguished (61) on the basis of their degree of depolarisation, pulse by pulse, in each distance gate for a defined pulse train. A statistical analysis of the number of echoes corresponding to the chosen selection criteria, for each distance gate and in the pulse train, makes it possible to distinguish the targets. <IMAGE>

IPC: B60R1/06
Filed: 1983-07-12
Abstract: A holder 1, for a rear view mirror 10, comprises a housing 5 accommodating a pivot shaft provided with a coupling pin 22 which is loaded by a pressure spring 25 and side engages in grooves in a base piece 23 which can be rotated by an electric motor 3 (Fig. 1) through a worm 13 and wheel 17. When the rear view mirror or the like 10 collides with an object, the coupling part or pin 22 is lifted out of the grooves 24 against the pressure of the spring 25 and when the impact of the collision has subsided, the coupling part or pin 22 will slide down into the nearest groove 24. The motor 3 is then brought into operation, by a push button control, in one or the other of two directions until the mirror has returned to its original position. The motor 3 may also be used for readjustment of the mirror. <IMAGE>
