Patent GB-2304240-A (GB)
Title: Static var compensator
Inventor: YOUNG DAVID JOHN
IPC: H02J3/18
Filed: 1995-08-11
Abstract: During the normal process of opening a switch at zero currents, a high charge is trapped on the series capacitor C in the compensator. After a further half cycle the applied voltage and the capacitor voltage are additive imposing a voltage exceeding twice the peak system voltage on the switch such as a thyristor T. According to the invention, the compensator includes a current-limiting inductor L and control means arranged to perform a sequence of switching operations on the thyristor thereby to cause an at least partly discharged condition of the capacitor means to coincide with a zero-current state of the series circuit. Preferably, the thyristor is switched OFF at zero current, then ON after a delay, following which the capacitor resonates with the current-limiting inductor and, at a point at which the capacitor voltage is near zero and the current is near zero, the thyristor is switched OFF again, leaving little or no offset on the blocked thyristor voltage. The blocking sequence may include more than one opening and closing operation before the final opening operation at the coincidence point. The mode of operation of the compensator reduces stress on the switch.

Title: Pumping source wavelength control rubidium atomic oscillator
Inventor: NAKAJIMA YOSHIFUMI
IPC: H01S5/068
Filed: 1996-04-23
Abstract: A rubidium atomic oscillator includes a conventional, frequency modulated, microwave feedback loop 4,7,8,12,13,14 and an optical feedback loop 22,23,26,27,28 to control the wavelength of the optical pumping source e.g. a laser diode 16. A second light beam split from the source 16 has its wavelength changed by an oscillator 21 and acoustic optical modulator 19 and the amount of light passing through the resonance cell 3 of a cavity resonator 2 is detected by photodetector 22 so as to provide a coherently detected signal for controlling the wavelength of the source so that the light is maximally absorbed in the gas cell. Alternatively (Fig. 7) a single light beam is passed through the cell and the peak value of the second harmonic of its frequency is used for coherent detection to control the wavelength of the source. The apparatus may be used as a source of an optical frequency reference signal and a microwave reference signal when using second harmonic generation of the light source to provide optical pumping (Fig. 9).

Title: Device for eliminating false radar blips injected from the digital memory of a scrambler
Inventor: GARREC PATRICK
IPC: G01S7/36
Filed: 1996-11-14
Abstract: A device for eliminating false radar blips injected from the digital memory of a scrambler comprises apparatus 21 for modulating the radar transmitted power from a recurrence to another and adapted to distinguish between real blips and false blips generated by the scrambler, where real blips and false blips vary to different extents in accordance with the law of transmitted power modulation. It can be applied in particular to radars operating in a scrambled 15 environment, for example surveillance or battlefield radars. The scrambler operates with a digital radio frequency memory to re-transmit a received radar pulse during a succeeding radar period. With the change in transmitted power during that period, the false echo is apparent at the radar. By varying the radar gain 25, 27 in an inverse manner to the change in transmitted power, the time echoes can be made to appear as fixed amplitudes whereas false echoes vary from period to period.

Inventor: VAELIKANGAS SAKARI
IPC: G06F1/16
Filed: 1997-02-07
Abstract: When using an external keyboard with a notebook computer, the integral keyboard prevents the screen from being located at the optimum distance from the user. So that the external keyboard can be placed nearer to the notebook's screen, said screen may be capable of rotating through 270‹ about its hinge from the closed position, allowing the notebook to be placed with its integral keyboard face down on a work surface thereby permitting location of the external keyboard nearer the screen. Alternatively, with the screen open to an angle of 270‹ the notebook can be stood on its ends in an "A" shaped configuration. In this mode the screen display needs inverting. In a further mode the screen is detachable and may be relocated at the end of the integral keyboard which is nearest the user. Alternatively, the screen can rotate about an axis perpendicular to its hinge.
