Patent GB-2062335-A (GB)
Title: Recording Clock Tracks
IPC: G11B27/32
Filed: 1979-10-08
Abstract: In a method of treating a multi- track magnetic tape to provide a clocking track for use in timing signals recorded on the other tracks, a train of logic pulse is recorded simultaneously on each data track, the data tracks are replayed, their outputs are gated such that a resultant signal occurs only when their outputs are all the same, and this resultant signal is recorded on the clock track. Thus, there are no clock pulses on the clock track at positions corresponding to drop-out- causing imperfections in any one of the data tracks so that no attempt will subsequently be made to write or read the data tracks at these positions.

Patent GB-2036344-A (GB)
Title: Load-measuring devices
IPC: G01L1/22
Filed: 1979-11-21
Abstract: A load-measuring device comprises a ring to be interposed between two opposed bodies coaxial with the load axis. Circumferentially- spaced projections 2 separate one axial face of the ring from one of the bodies, and similar but angularly- staggered projections 3 separate the other axial face from the other body, so that when the bodies-approach under load the ring is distorted to an undulating shape. The distortion may be measured by a set of strain gauges R1-R16 fixed to the axial faces of the ring, and the output of a second set of gauges D1-D16 fixed to the radial faces of the ring may serve to compensate for distortions of the ring caused by things other than axial thrust, e.g. temperature variation. The projections may be fixed to the ring, or fixed to and located by the ring casing so that they bear against the ring in use. <IMAGE>

Patent GB-2046039-A (GB)
Title: Method and apparatus for detecting the direction of a fault on an electrical transmission line
IPC: G01R31/02
Filed: 1980-03-18
Abstract: The detection of the direction of a fault on an electrical transmission line in the case of faults close to the measuring station is problematical because of the low measuring voltage, particularly for bipolar short-circuits, with which the measuring voltage UK appears as the difference between the phase voltages U'S, U'T which have a small difference in phase angle. Measuring errors and deviations in the measuring channels can then lead to extensive errors in the decision regarding direction. The invention solves this problem by introducing an additional phase angle  alpha  into the phase position of at least one of the phase voltages U''T used for the formation of the fault measuring voltage UK. <IMAGE>

Patent GB-2047506-A (GB)
Title: Method and apparatus for securing data transmissions
IPC: H04L9/18
Filed: 1979-04-19
Abstract: The security of data transmissions between stations such as A, B, and the control of secured transactions from remote locations in a data-transfer system is improved by obviating the need for transmitting user-identification information such as personal identification number (PIN) from station to station, e.g., from the station A utilized by the user to enter his PIN and initiate a transaction, to the station B that processes the transaction. For this purpose an intermediate station 114 is provided, and at this station 114 are stored the identification numbers PINA and PINB relating to stations A and B respectively. Thus, a message is encoded at A by logical combination with PINA, and the encoded message is transmitted to intermediate station 114 where it is decoded with the help of the stored PINA. The decoded message is then encoded at station 114 by logical combination with the stored PINB, and this encoded message is transmitted to the station B where it can be decoded with the help of the PINB available at that station. The processes of encoding and decoding are similar to those described in Patent Specification No. 2020513. <IMAGE>

Patent GB-2069297-A (GB)
Title: Resolving a wanted signal
IPC: H04B1/12
Filed: 1981-01-19
Abstract: In a method of resolving a useful signal from a band limited signal with a superimposed noise signal, a received signal m(t) is converted into digital values m(ti) which are then fed to a microprocessor (3) for processing. The microprocessor (3) generates a simulated digital noise signal   <IMAGE> where ai are approximation coefficients which vary slowly with time and ci(t) are formulation functions chosen according to the characteristics of the signals to be processed. The simulated noise signal is subtracted from the digitized input signal to yield the wanted, useful signal n(ti). By allowing the microprocessor (3) to vary the rate at which the values m(ti) are produced, cancelling of the actual noise signal S(t) with the simulated noise signal @(t) can be performed without introducing delay distortion into the useful signal n(ti) and without varying the formulation functions ci(t). <IMAGE>

Filed: 1981-02-11
Abstract: In a pipelined digital signal processor control circuits receive a single normal instruction during each processor cycle, each instruction including a plurality of fields which are directed to and control concurrent operations in respective stages of the pipeline in that cycle. During each processor cycle, each processing stage performs an operation relating to a different expression than the other processing stages are performing during that processor cycle. A single common bus is time-shared during each processor cycle to transfer the single normal instruction to the control circuits, to transfer data words to the arithmetic section, and to transfer the resultant data word to an output destination. As described the processor is a multiplier using Booth's algorithm. The pipelined sections include a multiplier forming successive partial products, an accumulator accumulating those products, and a rounding circuit to round the accumulated product.

Patent GB-2096854-A (GB)
Title: Improvements in and relating to direction finding systems
IPC: G01S3/48
Filed: 1981-04-15
Abstract: A wide aperture direction finding system has a circuit block 8 which can be time-shared between antenna pair N and S and antenna pair W and E. The signals dependent on the phases of the signals received at each antenna of a pair are added and subtracted. The sum output is multiplied in a multiplier 18 by sin  omega t, and the difference is 90 DEG -shifted and then multiplied by cos  omega t in a multiplier 26. This produces a combined output which is amplitude-modulated with a waveform whose frequency is dependent on  omega t and whose phase relative to  omega t is dependent on the phase difference of the incoming signal with respect to the two antennas. This process is then repeated on the other pair of antennas. The amplitude-modulating waveforms are extracted by a receiver 32 and processed to produce signals respectively dependent on the phase difference between the incoming signal and the two pairs of antenna. These phase difference outputs may represent only the fractional values of the total number of phase cycles, and they are converted into the two total phase values,  phi 1 and  phi 2, in a signal processing unit 40 which is responsive to the antenna separation, the wavelength of the received signal, and the approximate bearing of the incoming signal which is obtained from a unit 48. The ratio of  phi 1and  phi 2 is taken, and this is the arctan of bearing angle. Unit 48 may be a modified form of block 8. <IMAGE>
