Patent GB-824794-A (GB)
Abstract: 824,794. Calculating - apparatus. SCIENTIFIC LEATHER MEASUREMENT Ltd., DIAMOND, S. J., and CARTER, W. J. N. Feb. 10, 1958 [Feb. 15, 1957]. No. 5273/57. Class 106 (1). Tubular calculating apparatus comprises a board, a column of characters b designating types of articles, an adjacent and parallel slide c bearing a scale of article sizes and an index mark h alignable with a selected character of the column b, a chart i comprising columns of figures representing amounts of material required for articles of various types and sizes in accordance with different values of the proportion of the material usable, and a reading member k extending across the columns and movable in a direction parallel thereto. The apparatus described is for use in determining the area of leather required for a particular type and size of shoe allowing for a selected cutting coefficient. The slide c is set with its mark h against a character of the column b corresponding to a type of shoe and the reading member k is aligned with the size of the shoe on the scale c, whereupon the required area may be read from the chart i in the column corresponding to the cutting coefficient o, which coefficients are marked on the reading member. The latter and the scale c may be of transparent plastic material with their markings inset in the under surfaces. The reading member has guides f engaging in grooves in the edges of the board. One of the guides has springs r to impose a frictional load. The scale c is dovetailed in a groove of the board and has toothed ends c<SP>1</SP> to facilitate its manipulation. The lefthand portion of the board may be marked with lines corresponding to the rows of the column b. The various surfaces may be covered by transparent material.

Title: Simulating field of view for weapon training
Inventor: STICKEL DR ROBERT
IPC: G06T15/10
Filed: 1983-01-31
Abstract: For simulating visual reconnaissance on training equipment for firing practice, images of a panorama with superimposed target, e.g. a tank, are projected on a curved screen (22) from one or more T.V. projectors (20), the images (BI-III) joining smoothly.

Title: Vehicle radiator grille with shuttered operation
Inventor: PHILLIPS STEPHEN HUGH
IPC: F01P7/12
Filed: 1983-10-07
Abstract: A radiator grille positioned in the vehicle bodywork (2) above or below (not shown) the vehicle bumper (3) consists of an assembly of louvres fixed (12) and movable (13) which operate to open and close the main air inlet for cooling airflow (7) to the radiator (8) a second smaller fixed air inlet aperture (6) also provides cooling airflow (7). The movement of the louvres (13) is governed by a sensor (23) of the engines coolant temperature. The movable louvres (13) remain closed for certain conditions such as high speeds and warm up periods until the engine coolants temperature determines their operation.

Title: Means for pneumatic gathering of milled peat
Inventor: LINDHOLM JUHANI
IPC: B07B9/02
Filed: 1983-10-28
Abstract: For gathering milled peat, a gatherer carriage (2) for moving over a bog is provided with suction tubes (5), a cyclone (11) for separating the peat from the suction air, a receptacle (6) wherein the peat collects, and a blower (3) for producing suction. The receptacle (6) is made bipartite so that one part (9) of the receptacle, to which the peat and suction air are first conducted, collects the coarser peat particles, and the other part (10) collects the finely divided peat particles separated from the suction air by the cyclone (11). The partition separating the parts (9 and 10) of the receptacle (6) may consist of a flap (8) provided with hinges and which, when the receptacle is being emptied, opens under gravity. As a result, only part of the peat to be gathered goes through the cyclone and therefore the wear of the cyclone will be less, and the cyclone can be dimensioned smaller and lighter than previously. <IMAGE>

Patent GB-2138183-A (GB)
Title: Multi-processor system
Inventor: MCWILLIAM ANDREW JOHN
IPC: G06F13/362
Filed: 1984-01-28
Abstract: Where several processors are used in a multi-processor system, e.g. in digital signal processing, they are interconnected by a System Bus. If a processor (e.g. DSP1) needs a data transfer to or from another processor, it sends out a bus request signal to a Bus Arbitration Logic (BAL), which allots the bus to the calling processor if it is free. If not, the calling processor tries again. If two processors call at once, the arbitration logic selects one to have access to the bus. When such an allocation occurs the calling processor emits the address of the wanted processor for decoding at DAD, as a result of which the calling and called processors are interconnected for transfer via direct memory access processors in the two processors included in the transfer. <IMAGE>

Title: A pattern examining method
Inventor: MASUDA TATSUNOSUKE
IPC: G01B11/24
Filed: 1984-04-08
Abstract: To detect defects in a pattern 12 which comprises two areas 1 and 2 having different reflection or transmission coefficients (e.g. a printed circuit), picture signals obtained by photoelectrically scanning the pattern are compared with those from a reference pattern and areas 13 which have no significance to the function of the pattern are excluded from the comparison by the use of a material having a further different reflection or transmission coefficient. Thus areas 13 of the reference pattern or of an auxiliary pattern are painted with black or white paint and their picture signals are digitised using two thresholds and stored for later comparison with patterns under examination. <IMAGE>

IPC: H04N7/025
Filed: 1985-01-10
Abstract: A communications system comprising a head end 2 and a plurality of subscriber units 7-10 each provided with a receiver 7 for receiving transmitted programme signals. A digital signal representative of a message to be delivered to any one subscriber unit is transmitted from the head end. The transmitted digital signal is converted at the subscriber unit to an output signal which can be reproduced 10 as an audible message by the subscriber unit, and the subscriber unit is selectively controlled to reproduce the audible message. The subscriber units may be radio receivers or terminals of a cable television system comprising a trunk cable network connecting the head end to a plurality of switching centres 1, and a number of subscriber cables 3 connecting the subscriber units to the switching centres. Television signals are transmitted from the head end over a plurality of channels in the trunk network and switched to individual subscribers from the switching centres in response to control signals 5 transmitted to the switching centres from individual subscribers. Signals are transmitted from the head end to control the switching centres such that a subscriber's receiver is selectively connected to the channel on which the digital signals are transmitted, whereby audible responses can be transmitted selectively to subscribers. <IMAGE>

Title: Driver circuit for solenoids
Inventor: FORSTER KENNETH IAN
IPC: H01H47/10
Filed: 1985-11-29
Abstract: The invention relates to a circuit for driving current through the winding of a solenoid 10, e.g. in an engine fuel injection system. The circuit has a current output stage comprising a first transistor 14 having a current switching path connected in a series path containing the winding 10 and a heat dissipating resistor 16, and a second transistor 12 having a switching path connected directly in series with the winding 10 and in parallel with the series combination of the switching path of the first transistor 14 and the resistor 16. Diodes 26,28 ensure that second transistor 12 is only conductive until the current through the winding 10 reaches a preset value. Both transistors are controlled by negative feedback derived from a common emitter resistor 20 coupled to a comparator amplifier 34. The resistor 16 prevents excessive power dissipation in the transistor 14 but is bypassed initially by the transistor 12 to avoid limitation of the current rise time. <IMAGE>
