Patent GB-2088167-A (GB)
Title: Preventing Damaging Electric Fields, e.g. in SAW Devices
IPC: H01L41/22
Filed: 1981-10-12
Abstract: In devices comprising closely spaced metallised regions deposited upon a dielectric substrate, in particular acoustic wave devices, electric fields may arise between the regions due to pyroelectric effects or acquired static charges during production or subsequently. These fields can cause damage by arcing or cracking of the substrate. This problem is overcome by the provision of resistive links between such regions so that the fields do not arise. Preferably the links are of metallising formed simultaneously with the metallised regions. Application to a SAW convolver is described in which the links are strips of metallising (7, 8, 9). <IMAGE>

Patent GB-2123681-A (GB)
Title: Store for object(s), e.g. wine bottles
Inventor: SIR PATON WILLIAM PROF
IPC: A47B73/00
Filed: 1983-04-13
Abstract: A support structure (for e.g. wine bottles) comprises two abutments A1, B1 which are both horizontally and vertically spaced and separated by a free 'insertion path'. The arrangement is such that when an article is inserted therebetween in such manner that the centre of mass of the article remains on the side of A1 remote from B1, the moment generated by the mass of the article acting about abutment A1 is exactly countered by the opposing moment generated by reaction against abutment B1. In practice the abutments may be formed by the edges of an aperture through a vertical panel X, the aperture being inclined at an angle ??? to the horizontal and its diameter Rh being selected so that a bottleneck, when inserted, is held in a substantially horizontal position as shown in Fig. 2. Other embodiments include skeletal arrangements of wire forms (e.g. rods, rings, etc.) (Figs. 5-8) and an apertured oblique lamina (Fig. 9) forming part of a concertina folded strip. A theoretical treatment of the principle is given. <IMAGE>

Title: Crane safety device
Inventor: JAMES NIGEL ANTHONY
IPC: B66D1/54
Filed: 1983-07-30
Abstract: A safety device for a crane in which a motor (2) has an output shaft which drives a hoist barrel (4) via a speed reduction drive train (6). The motor output shaft and the hoist barrel are each provided with a digitiser (12, 14) which produces a pulse train at a rate dependent on the speed of rotation of its associated part. The number of pulses produced by the motor digitiser (12) is accumulated in a time period determined by the time taken for ten pulses to be produced by the hoist barrel digitiser (14). The accumulated number of motor digitiser pulses is compared with a preset value and if it is less than that value a relay (10) is operated to cut off the power supply to the motor (2) and apply a brake (8) to bring the hoist barrel (4) to a halt. <IMAGE>
Patent GB-2125591-A (GB)
Title: Checking sequential logic circuits
Inventor: HOWARTH JAMES
IPC: G06F11/08
Filed: 1983-08-09
Abstract: A sequential logic circuit includes means for checking, while the circuit is in operation, that it is stepping correctly from one state to the next. The current state of the circuit is encoded as X0-X3. That encoded value is compared with a predicted value Y0-Y3 derived in response to the previous state of the circuit itself and those signals that cause the transition from the previous to the current state. If the two do not match the circuit has not stepped to the correct state. Reduction in hardware is achieved by allowing certain states to share the same encoded value. <IMAGE>

Title: Method for correcting picture signals in image input equipment
Inventor: MITSUKA IKUO
IPC: H04N1/19
Filed: 1985-02-27
Abstract: In deriving picture signals from a multi-element sensor (1), instead of conventionally obtaining the ratios of picture signals to (white) reference signals, the dark signal of each element in turn is held in a D.C. clamping circuit (3), so that it can be subtracted from the element signal which is then stored in holding circuit (4). The corrected reference signals are transferred therefrom to RAM (6), and subsequently read out so that the ratio of the corrected picture signal from (4) to the corrected reference signal for the same element is derived in dividing circuit (2). <IMAGE>

Patent GB-2195503-A (GB)
Title: Resetting system for vehicle direction indicators
Inventor: SALES MICHAEL PETER
IPC: B60Q1/42
Filed: 1986-09-18
Abstract: A direction indicator control member 10 is reset in response to an electrical signal generated by rotation of the steering column. The signal energisers a solenoid 26 whereby a pin (47), (Figs. 3,4) pushes against a cam block (43) to reset the member 10 to its central off position; alternatively pin (47) may be moved away from block (43) to allow member 10 to be reset by spring bias. Moving member 10 for a left or right indication establishes a circuit from the battery 15 to a switch 16 via a contact 14 or 12 respectively, the switch 16 completing the circuit to solenoid 26 when the steering column is turned in the opposite direction to that signalled thereby to change the position of switch 16 via lug 32 or 34 acting on a yoke 28. Alternatively, the direction of steering column rotation may be sensed by an electronic circuit associated with magnets on the steering column or with a photodetector arrangement. The system allows the control member 10 to be remote from the steering column. The rotation sensor 16 may be attached to a lower part of the steering column remote from any tilting mechanism thereon. <IMAGE>
