Patent GB-2260234-A (GB)
Title: A radar apparatus
Inventor: VOLES ROGER
IPC: G01S13/524
Filed: 1983-11-22
Abstract: A radar includes an antenna (10) arranged to generate sum and difference signals VS VD in respective channels C1, C2. Signals in the difference channel, corresponding to consecutive pulses, are shifted in phase by +/- pi /2 respectively, and their amplitudes modified adaptively by a weighting factor  gamma . The weighted and phase shifted signals are combined vectorially 18 with their respective sum signals to produce resultant signals which are compared in a two pulse canceller (20). Any residual signal is minimised in circuit (22) by suitably adjusting  gamma . The value of gamma  necessary to achieve a minimum at the output of the two pulse canceller is related to the component of angular velocity of a rotating target which is normal to the plane of the difference pattern of the antenna. A dual axis radar can be used enabling evaluation of two, orthogonal components of angular velocities of a rotating target (a ship undergoing yaw and roll movements). A single axis radar could also be used to eliminate Doppler broadening due to the effect of vertical wind shear on clutter. <IMAGE>

Title: Multilayer composite structure
Inventor: GENOVESE JOHN SALVATORE
IPC: A47K3/00
Filed: 1984-07-11
Abstract: The structure is formed of a substrate having bonded to it a finished layer on one side, and on the other side a layer of plastics (which may be reinforced) is chemically bonded to form a laminated structure. The plastics layer has a thickness and a density such as to provide the product with resistance to high impact and/or thermal shock. The finished layer is resilient to delamination when subjected to relatively high impact applied directly to the finished and/or plastics layer surface and to delamination when the composite structure is subjected to a sudden temperature change. The substrate may be steel and the finish layer on one or each side may be enamelling. The composite structure is suitable for a sanitaryware product such as a bathtub.

Title: Checking coins
Inventor: ROBERTS MARKS
IPC: G07D5/08
Filed: 1984-12-05
Abstract: The arrival of a coin in a coin checking apparatus is detected by arranging for the coin to hit a member (16). The vibration caused by the impact causes a piezoelectric element (36,36a) to give a transient output signal which is used to switch on electronic circuitry of the coin checking apparatus. The circuitry is normally switched off and thus over a period of time the average power consumption of the coin checking apparatus is low so that it can be satisfactorily run from a battery.

Patent GB-2187890-A (GB)
Title: Positional sensor
Inventor: HOWARTH NEIL MARGERISON
IPC: G08B13/08
Filed: 1987-03-13
Abstract: A positional sensor for an intruder detection alarm system includes a pair of reed switches 11, 12 disposed in close proximity and at right angles to one another to provide a cross-over point at each switches respective middle. If a bar or rod magnet 13 is located above the cross-over point perpendicular to the switches 11, 12 there is no operation of the switches as the applied magnetic field's components are of equal strength and opposite polarity on each of the switches 11, 12. If the magnet 13 is displaced laterally one or both of the switches 11, 12 will operate due to the field imbalance in the nett resulting magnetic field. A third reed switch (not shown) may be included to sense the absence of a magnetic field. <IMAGE>

Patent GB-2191290-A (GB)
Title: Depth gauge
Inventor: MACLEOD IAIN
IPC: G01B5/18
Filed: 1987-06-05
Abstract: A depth gauge is disclosed which has two parallel legs (20,22) which when one of the legs (22) is moved relative to the other one because of a difference in height, ie. due to a false bottom (14) in a case, an indication of the difference in height is given. The parallel rods (20,22) are coupled by a parallelogram linkage 24. One of the rods has right angle sector (34) fixed to it and a movable sector (30) fixed to the linkage overlaps it. Relative movement of one of the rods causes movement of the sector 30 relative to the fixed sector 34. By calibrating the periphery with a scale for depth it is possible to determine the thickness of the false bottom (14). The legs can be extended for use with deeper or different sized containers. <IMAGE>
Patent GB-2201569-A (GB)
Title: Data display memory addressing system
Inventor: CURRIE STEPHEN ROBERT
IPC: G09G1/16
Filed: 1987-12-15
Abstract: Data is held in a display memory 12 and then read out sequentially to produce the display by apparatus including a controller device 14, e.g. a conventional CRT controller chip, which generates a sequence of addresses. The controller is driven by a clock signal, which causes the controller to increment its address at each clock beat. The actual address for the display memory has the clock signal as its least significant bit, the remaining bits being provided by the address from the controller. In this way, two locations in the display memory are accessed for each address from the controller so that the rate of access of the memory is doubled. <IMAGE>
Patent GB-2217150-A (GB)
Title: Voice/speech operated switch
Inventor: HODGSON RICHARD LINDEN
IPC: H03G3/34
Filed: 1988-03-05
Abstract: A filtered AF signal is amplitude-limited at 32 and FM-demodulated at 34. The frequency modulation is low-pass filtered at 38 and the amplitude of the positive and negative portions of the resultant waveform are threshold-compared by comparators 50 and 58. The threshold is selected so as to discriminate against noise. The resulting pulses are fed into a pulse length gate 76 which measures the length of each pulse. When a pulse exceeding a predetermined minimum length is detected, an output on line 75 is fed through a re-triggerable monostable circuit 88 to produce a signal on line 26 which indicates a voice input to operate a gate 24. This gate operates as a squelch gate for a radio receiver or as a voice-actuated switching gate for a transmitter. <IMAGE>

Title: Dispensed optical fibre links
Inventor: BERRY DAVID JOHN
IPC: H04B10/00
Filed: 1988-05-07
Abstract: In an optical fibre dispenser, such as is used to dispense fibre into the environment as for the transmission of guidance commands to a remotely operated vehicle, a single coil is replaced by a series of coils, each of which is bypassed temporarily with a short-low-loss frangible link. By this method the Winding Increment of Attenuation of each coil is effectively "bypassed", enabling low power transmitter and receivers and in particular smaller diameter coils to be used. In one embodiment, four dispenser coils A, B, C, D have their fibres FA, FB, FC, FD joined in series enabling payout of the full fibre link to the effected. Each coil, except A, is by-passed by a parallel short low loss optical link LB, LC, LD, the joins being effected by Y-couplings YB1, 2; YC1, 2; and YD1, 2. Each link incorporates a local point BB, BC, BD such that tensile load on the link during dispensing of the fibre will break the link.
