Patent GB-2191726-A (GB)
Title: Scissors
Inventor: BAXTER WILLIAM JAMES
IPC: B26B13/00
Filed: 1986-06-19
Abstract: Cutting wallpaper in situ along the line of a corner between two adjacent walls or a wall and ceiling is difficult, mainly because it is not easy accurately to operate scissors in the rather cramped space in the e.g. wall-to-wall corner, nor is it easy to cut on a line that exactly follows the corner itself. The present invention seeks to solve this problem by proposing a form of scissors in which: firstly, the handles 12a,b are raked in the cutting plane to one side (so keeping the hands well out of the way of the two wall surfaces etc.); secondly, the lower blade 10b - the blade away from which the handles are raked - is extremely thin or narrow in the cutting plane (so allowing the scissors to cut right in the corner itself, without any substantial error as the material being cut is raised up out of the corner when the blade slides beneath it); and thirdly, the trailing (handle) end 21,22 of this lower blade is extended rearwardly in such a manner that in use it and its extension fit snugly into the corner (so forcing the scissors to remain aligned with the corner as the cut progresses). <IMAGE>

Patent GB-2179214-A (GB)
Title: Surge voltage protection arrangement
Inventor: HUNT ALASTAIR MARK
IPC: H02H9/06
Filed: 1986-07-31
Abstract: A surge voltage protection arrangement comprises one or more gas discharge tubes such as T1 and includes at least two gaps J and G defined by electrodes of the one or more gas discharge tubes. Two of the electrodes a and c which are separated by at least one other electrode b are connected between two conductors L1, L2 of a circuit to be protected and a capacitor C is connected between one of the conductors and the intermediate electrode b. The capacitor responds to an impulse overvoltage to cause initial breakdown between the intermediate electrode b and the electrode c which in turn initiates breakdown between the electrodes b and a. In this way the impulse sparkover voltage can be made to approximate to the D.C. sparkover voltage. The arrangement may employ triggered gas discharge tubes, or two electrode gas discharge tubes or a combination of both types of tube.

Title: Interference cancelling receiving array system
Inventor: HEYNINGEN ARENT H KITS VAN
IPC: G01S7/52
Filed: 1988-08-03
Abstract: The direction of a received beam from an interfering source 12 to an array 11 is obtained using a beamformer 14 giving the best estimate of this signal. The beamformer output is fed into an inverse beamformer 25 in such a way that the total delay experienced by a signal from any element of the array 11 is the same as that of other elements in the array 11. Each output from the inverse beamformer 25 is a spatially filtered replica of the signal received by the corresponding array element except for a fixed time delay constant for each element. The same delay is imparted by delay circuits 27 in a second channel 6 to each of the array outputs which are subtracted by subtractor circuits 28 from the corresponding inverse beamformer outputs. When the amplitude and delay of each signal to the subtractor circuits 28 will no longer contain signal components from the direction of the interfering signal. Delay and amplitude error signals are generated in the second channel 6 to control the delays and amplitudes provided by the inverse beamformer 25. <IMAGE>
