Title: Noise suppression circuit or a video signal
IPC: H04N5/21
Filed: 1982-04-30
Abstract: In a noise suppression circuit comprising a subtracting circuit (5), a non-linear circuit (23), an adder circuit (9) and a delay circuit (15), the non-linear circuit is simplified by applying the input signal of the noise suppression circuit to the subtracting circuit (5) and to the adder circuit (9) and the output signal of the noise suppression circuit to the subtracting circuit (17) via the delay circuit (15). Then the non-linear circuit is connected between an output (19) of the subtracting circuit (5) and a further input (27) of the adder circuit (9), and is given a transfer factor equal to unity for signals applied to it having low amplitude values, the transfer factor decreasing towards zero with increase in the amplitude value of the applied signal. <IMAGE>

Title: Plastics material mesh structure
Inventor: MERCER FRANK BRIAN
IPC: B29D99/00
Filed: 1982-10-04
Abstract: In order to provide uniaxially-stretched and biaxially-stretched mesh structures which allow for different specific designs of the interconnecting strands, a special punching pattern is used to provide holes 2, 3 in the starting material 1. The starting material 1 has a "square" pattern of large holes 2. Further holes are added. These further holes can be small holes 3 which are staggered and in pairs. When the starting material is stretched, the uniaxially-stretched structure has transverse bars 9 interconnected by highly orientated strands 6 each of which forks at both ends into further highly orientated strands 8, providing a structure which is particularly suitable for soil reinforcement. When the structure is stretched in the direction at right angles to form a biaxially-stretched structure, the zones of the bars 9 which are between aligned strands 8 remain as unorientated or partly orientated junctions 19. The remaining zones of the bars 9 are stretched out to form highly orientated strands 15, 17. This biaxially-stretched structure is particularly suitable for soil stabilization.

Abstract: The radiator 4 of a vehicle engine 1 is divided into two sections which can be connected by means of a thermostatic valve 7, of which the one section 4b through which cooling fluid always flows, serves both as a heat exchanger and also as a radiator, and the other section 4a serves merely as a radiator. The radiator 4 is arranged between the engine 1 and the passenger compartment 5, so that an inflow pipe 2 and a return flow pipe 3 are necessary for connecting it to the engine. The section 4b of the radiator which serves as a heat exchanger is here in communication via an air conveyance passage 10 with the passenger compartment 5. An air inflow pipe 11, 13, is provided whereby the air flowing in is not only conveyed via the heat exchanger 4b, and according to the position of guide valves 18, 20 conveyed either into the passenger compartments or into the open air as desired, but also conveyed into the passenger compartment 5 bypassing the heat exchanger 4b. The air flowing through the other section 4a can, if necessary, be conveyed with the air flowing through the heat exchanger 4b, through a further air conveyance passage 8 containing a cooling fan 9, into the open air. <IMAGE>

Title: Dual use of ranging radio
Inventor: DANO PAUL K
IPC: G01S13/76
Filed: 1983-09-28
Abstract: A radar interrogator (58, 100, 102) transmits an indefinite stream of radar pulses (108) to a transponder (56) at a fixed pulse repetition rate. An encoder in the transponder (56) selectively encodes a binary word representing information data (e.g.the angle subtended by two beacons (54, 56: fig.1, not shown)) to be transmitted some of the radar pulses. For example, alternate radar pulses may be inhibited (at 116) or not, to transmit the information, whilst the remaining radar pulses are retained for maintaining the distance measuring system operation. In other systems up to four successive pulses may be dedicated to a transmission of data. The same system may be used by the interrogator to transmit information. <IMAGE>

Patent GB-2151062-A (GB)
Title: Coin validator
Inventor: SHOUKSMITH ERIC
IPC: G07D5/08
Filed: 1984-11-05
Abstract: A coin validator comprises a microprocessor (4) which is periodically activated to check the output of an arrival sensing circuit (6) to determine whether a coin has arrived. The circuit (6) includes a printed circuit inductance (10) and produces an output signal the frequency of which alters when a coin arrives and is used to indicate coin diameter. The circuit (6) is designed so that output amplitude variations are minimised. Arrival of a coin causes powering- up of a material/thickness sensing circuit (8). In one embodiment both the frequency and amplitude of the output signal from this circuit are used to determine the denomination of the inserted coin. The amplitude profile may be used to determine when to measure frequency, and which of a plurality of successive amplitude measurements are to be combined to provide an averaged amplitude value. A counter (24) is used for frequency and amplitude measurement, and for periodically activating the micro-processor (4). Coins are rejected if they travel too quickly through a testing station of the validator. The validator is operable in a test mode to indicate, in response to an inserted coin, how the sensing circuits (6,8) should be adjusted to provide optimum operation. <IMAGE>

Title: A content addressable memory
Inventor: SZCZEPANEK ANDRE
IPC: G11C15/00
Filed: 1985-11-08
Abstract: In a content addressable memory a plurality of equal-sized groups of data bits are accessed simultaneously from a memory and simultaneously compared with each group in turn of a sequence of groups from an input key code, each group consisting of the same number of consecutive data bits. Each comparison of groups of data bits produces a match indication, and a comparison of groups of data bits is inhibited unless the comparison of the preceding group of memory data bits with the preceding group of key code data bits produced a positive match indication. The match indications are stored in a shifting register which is stepped along one step after each comparison to permit or inhibit the next comparison. The memory may be a dynamic semiconductor RAM accessed a row at a time. The data bits from a single row access may be compared simultaneously with each group in turn of a plurality of groups of data bits, say 4, constituting the entire input key code. <IMAGE>
