Title: Movement Detection Circuit
IPC: G01P13/00
Filed: 1981-07-24
Abstract: In a movement detection circuit for an interlaced television signal to be applied to an input (3), a delay circuit (5) of substantially one field period feeds delayed and undelayed signals to a comparison circuit (15) which in turn feeds an output circuit (42), a sign reversal detection circuit (126) being provided for use in obtaining a movement indication signal at an output (137) of the output circuit (42). By the use of the sign reversal detection circuit (126) the previous need to use a delay circuit providing a delay of a picture period is overcome. <IMAGE>

Title: A pin cushioned in a body, for example a body of a track for a tracked vehicle
IPC: B62D55/088
Filed: 1981-08-03
Abstract: There is described a rubber- cushioned pin (15) for a tracked-vehicle track, said pin having rubber rings (20 - 23) vulcanised thereon and being pressed into a bore (36), provided for the pin, of a track body (1), the stability of said pin (15) being increased in that the rubber rings (20 - 23) are adhered by way of an adhesive coating (26) to the wall of the bore. Instead of hitherto- used tube body material, namely steel, and hitherto-used rubber rings, other material pairings having lower friction values than previously, such as plastics materials, fibre-reinforced plastic materials, and non-ferrous metals, can be used for the track bodies, and other elastomeric materials instead of hitherto- used rubber can be used for the rings. The invention is also applicable to an arrangement, having a pin cushioned in a bore by elastomeric material, in which the bore is in a body other than a body of a tracked-vehicle track. <IMAGE>

Title: A radar for the detection and discrimination of tracked vehicles
Inventor: VOLES ROGER
IPC: G01S7/41
Filed: 1982-02-26
Abstract: A radar apparatus (Figure 7a) is arranged to identify a "ripple" in the frequency spectrum of returns, indicative of a track of a tracked vehicle, by correlating the frequency spectrum with a reference waveform (L1), indicative of a track. A sequence (S) of electrical signals, representing the amplitudes of returns of successive frequencies is loaded into two shift registers (SR1, SR2). The storage locations in each shift register are weighted by respective amounts corresponding to the reference waveform (L1); in the case of SR1, and the complement (L2) of that waveform in the case of SR2. The signals are cycled through the shift register once and the weighted outputs A, B compared. When A is greater than * small Greek alpha *B a target is declared. The frequency spectrum can be correlated with a number of different reference waveforms (Figure 7b).

Title: Gas flow control apparatus
IPC: F23N5/24
Filed: 1982-04-14
Abstract: In a gas-fired domestic hot water boiler or other apparatus having a double-solenoid series gas valve comprising a pair of individually operable solenoid valves 1, 2 in series with a relatively small gas volume 27 between them a pressure transducer 29 positioned between the stop valves is connected via an electronic monitoring circuit with the control means for the valve solenoids 15, 25. The monitoring circuit 28 permits the valve control circuit to admit gas to the burner only after an initial automatic testing sequence, in which the first valve is held open with the second valve closed, the states of the two valves then being reversed (in each case for a pre-set time). The transducer must detect supply pressure in the first stage of the test, and atmospheric pressure in the second, thus proving the closing integrity of both stop valves. <IMAGE>

Title: Hydraulic pulseless supply means
Inventor: JONES PHILIP
IPC: F04B9/117
Filed: 1985-05-14
Abstract: Hydraulic pulseless supply means comprises two hydraulic ram-pumps (1 and 2) arranged to deliver a combined pressurised output, and control means (40 to 49) for controlling the operation of the two ram- pumps such that the delivery strokes of the two ram-pumps overlap to produce a uniform, substantially pulseless pressurised output. The control means is operative to control valves (10,11,16,18) which determine the phasing of the delivery strokes. The valves are arranged so that during the delivery stroke of one ram-pump the flow of driving fluid thereto is reduced by passage through a restriction (12 or 13) and the other non-pump starts its delivery stroke in response to the application thereto of a full flow of driving fluid. A pump 6 provides the driving fluid. <IMAGE>

Title: Method and system of controlling the operation of a coal working machine
Inventor: SKOCZYNSKI WOJCIECH
IPC: E21C41/18
Filed: 1985-12-17
Abstract: A method and system for controlling the operation of a working machine in the mining industry, and which can be employed in working coal by the longwall system, solves the problem of selecting the optimum operating parameters of the working machine with regard to working power consumption, coal cuttability and workability, and yield of coarse coal depending on the properties of the seam being worked. The method consists in predetermining the most advantageous value of the load of the drive unit and of the food rate of the working machine and then controlling these parameters during the working so that after at least one of the controlled parameters changes, the supporting capacity of a section of the hydraulic support and the feed rate is corrected to suit the existing load. According to this invention, the drive unit 16 of a working machine 17 is connected to an analyser 18 in the system which analyser is in turn connected to pressure relief valves 15 and prop displacement sensors 19 of the individual sections of the hydraulic support. <IMAGE>
