Title: Improvements in or relating to devices for protecting series capacitors
Inventor: DEY PHANIBHUSAN
IPC: H02H7/16
Filed: 1957-11-13
Abstract: 838,150. Protective arrangements. BRITISH INSULATED CALLENDER'S CABLES Ltd. Nov. 13, 1958 [Nov. 13, 1957], No. 35421/57. Class 38 (5). [Also in Group XXXV] A capacitor in series with say an A.C. transmission line is protected against over-voltages by a spark gap and a gas discharge switch, both in parallel with the capacitor, the switch providing a conductive path when the spark gap breaks down. A capacitor 1 in series with a transmission line 2 is shunted by a series circuit comprising current limiting impedances 28, 29, resistors 26, 27 and spark gap 25. The resistance-spark gap combination is shunted by a pair of reverse-parallel connected ignitrons 5, 6 whose igniting electrodes 9, 12 are each connected to one of the gap electrodes. When an over-voltage appears across the capacitor, the gap 25 conducts thereby firing the ignitrons alternately on each half-cycle until the overvoltage ceases. In another arrangement peaking transformers increase the voltage applied to the igniting electrodes. A double mercury pool valve may be used in place of the ignitrons. Rectifiers 16, 21 may be provided to block negative voltages from the igniting electrodes. The two current limiting impedances 28, 29 may be replaced by a common impedance, or alternatively may be omitted.

Patent GB-356701-A (GB)
Abstract: 356,701. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. May 8, 1930, No. 14201. Convention date, May 8, 1929. [Class 97 (i).] In a method of copying lenticular films without inversion a negative is illuminated with or without a colour filter from the side next the refractory elements through an objective equal in function to that by means of which the negative was taken, an optical projection system is placed between the negative and positive and an objective projecting an image of the negative on to the positive is placed in the plane which is conjugate with respect to the optical system to the plane corresponding to the plane in which the colour filter was placed when taking the negative. In the form shown a luminous plane E is arranged at the focus of a condenser L1 of focal length f1 so that rays travel in a parallel beam to the objective L2 of focal length f2 and equal in function to the lens by which the negative was taken. The negative N is placed in the focal plane of the lens L2 and a lens L3 of focal length f3 = f2 is placed at a distance f3 from the negative. A lens L4 of focal length f4 = f3 is placed at a distance 2f3 from L3 and the positive film P is placed in the focal plane of the lens L4 with the lenticulations towards the lens. With this arrangement the plane F1 corresponding to the plane of the negative filter is reproduced in the plane F2 constituting the plane of the diaphragm of the lens L4. All the rays reach the positive under the same conditions as the rays emanating from the object were received by the negative in taking the picture. Colour screens may thus be dispensed with when copying and an orthochromatically sensitized positive printed with white light. To eliminate the lateral diffraction spectra arising from the net of lenticulations on the negative diaphragms such as those indicated in Figs. 2, 3, 4, and 5 may be inserted in the planes Fl or F2 or in both. Specification 353,121 is referred to.

Filed: 1965-08-24
Abstract: 1,124,275. Frequency discriminators. RADIO CORPORATION OF AMERICA. 24 Aug., 1965 [14 Sept., 1964], No. 36410/65. Heading H3A. [Also in Division H1] A frequency discriminator may include an integrated circuit chip 10 wherein the capacitors 68, 70 and 72 are reverse-biased diodes, and is characterized in that the time constant of load resistances 54 and 56 with capacitors 68 and 70 is of the same order as the period of the carrier wave. The short time constant reduces the harmonic content and reduces the load on transformer 36, as a result of which the waveform at the transformer is more nearly a sine wave. The load on the transformer may be further reduced by including further rectifiers 100 and 102 between rectifiers 50 and 52 and their associated load resistances, Fig. 5 (not shown). The capacitance in the discriminator load circuit may be increased by connecting two further diodes 90 and 92, Fig. 3 (not shown) in parallel with 68 and 70, the cathodes of these diodes being connected respectively to earth and to a positive 2 volt supply. The capacitance of diodes 90 and 92 is nearly twice that of diodes 68 and 70 due to the additional capacitance between their cathodes and the substrate of the integrated circuit. The similarly poled diodes 68 and 70 of Fig. 1 may be replaced by oppositely poled diodes 96 and 98, Fig. 4 (not shown). One of the diodes 98 then exhibits increased capacitance, for equal junction areas, and the junction areas are varied to compensate for this and for the different capacitances to earth exhibited by the anode of rectifier 50 and the cathode of rectifier 52. The method of construction of the integrated circuit is similar to that described in Specification 1,124,274.
