Patent GB-881443-A (GB)
Abstract: 881,443. Charging condensers; starting prime movers. GENERAL MOTORS CORPORATION. Aug. 25, 1959 [Sept. 12, 1958], No. 29026/59. Class 38 (4). [Also in Group XXVII] In an ignition system (see also Group XXVII) a condenser 102 is charged by means of a transistor oscillator, comprising transistors 30, 32, which operates as a self-excited generator the transistors becoming conducting alternately. The A.C. voltage appearing at the end terminals of the secondary winding 18 is rectified by silicon diodes 90 and 92. The connections of the silicon diodes with the transformer and with the condensers 94 and 95 provide a voltage doubler circuit. When the breaker contacts 118 are in a closed position current flows through primary winding 112 of transformer 110 to earth and current is also permitted to flow through inductance 97 to charge condenser 102. When the starter motor 76 is energized the armatures 62 and 80 are moved to have a compensatory effect on the ignition circuit as the energization of the starting motor 76 will drop the output voltage of the battery.

Title: Generation of interlaced television signals by interpolation
Inventor: WESTON MARTIN
IPC: H04N7/01
Filed: 1991-02-11
Abstract: In order to generate an output video signal of interlaced form from an input signal of the same field rate, weighted contributions from lines of a plurality of fields of the input signal are taken to make each output line. Where the input signal is an interlaced signal at a higher number of lines, the input signal is as a first step converted to a non-interlaced signal having the said higher number of lines per field. The input signal is, as part of the interpolation, filtered with a filter function as illustrated in Figure 7. <IMAGE>

Title: Noise reduction of video signal
Inventor: SPENCER SIMON HOWARD
IPC: H04N5/21
Filed: 1991-10-08
Abstract: A circuit 8 for reducing noise on a video signal applies a variable amount of noise reduction in filter 10 in dependence on the value of the gain of the circuit (such as an imager) in which the video signal was generated, said value being encoded on the video signal. The gain of the imager gives a more accurate reflection of video noise than does comparing successive frames, since movements on the image can produce the same effect as noise fluctuations. <IMAGE>

Title: Waveguide connector
Inventor: KING BERNARD
IPC: H01P1/04
Filed: 1993-04-07
Abstract: A waveguide connector for connecting two waveguide sections end to end by means of flanges and screwed couplings or male and female spigot and socket connections. It is known to include a choke groove in the end face around the waveguide aperture to inhibit signal leakage and improve the match and insertion loss characteristic. In the present arrangement, the groove 9 is not continuous but is in segments, one along each long edge of the rectangular guide 5.

Title: User interface for a telephone
Inventor: RAUTILA HEIKKI
IPC: H04M1/72469
Filed: 1994-05-27
Abstract: The method solves the problem of remembering the directional assignments of the arrow keys used in scrolling the menus of telephones, particularly mobile phones. Such phones incorporate function menus which are scrolled using arrow keys. The method permits redefining the direction of scrolling determined by the arrow each time the device is used so that it corresponds to the users preferences. The principle is that the first time a key is pressed, the menu always goes to its first item regardless of the direction indicated by the arrow (down or up). The next times the arrow keys are pressed, they conform to the directional assignments of the arrows defined when the key was pressed the first time. <IMAGE>
