Abstract: 878,111. Echo-ranging; pulse radar. KELVIN & HUGHES Ltd. May 31, 1960 [June 18, 1959], No. 21025/59. Addition to 785,001. Class 40(7) In this modification of the parent Specification, means responsive to the slope of the leading edge. of the echo signal which controls time-base triggering either reduces variations in the time of triggering with variations in that slope or suppresses the display or recording of echoes when that slope is less than a predetermined value. In Figs. 1 and 2 a fixed time delay between the onset of the sea bottom echo at point X and the instant of time base triggering at point B 1  is effected by controlling constant current switches 13, 20 which discharge capacitor 14 from a fixed voltage V, with waveforms (c), (e) respectively and passing resulting waveform (f) to amplitude gate 21 which passes as a triggering signal only voltages below the level v. Switches 13, 20 may each be a resistor in series with a normally non- conducting diode; or a pentode may be used. In the arrangement illustrated by Figs. 3 and 4 the bottom echo (l) is limited and differentiated before application to amplitude gate 27; the limiter may be dispensed with and compression effected in the input circuit of the amplitude gate.

Title: Improvements in or relating to electric pulse code modulation signalling systems
Inventor: LEVY MAURICE MOISE
IPC: H03M1/00
Filed: 1949-08-15
Abstract: 670,369. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd. Aug. 8, 1950 [Aug. 15, 1949], No. 21180/49. Class 39 (i). [Also in Group XL (c)] A cathode-ray tube for use in a pulse code signalling system (see Group XL (c)), and having a known form of apertured coder plate 1, Fig. 2, and collector plate 14, is provided with a further collecting electrode 15 above plate 14 and arranged as a dynode, the electrons from which are emitted to an electrode 15a. The negative amplitude-modulated sample signal pulses are applied to the series-connected condenser 29 and resistance 30, the upper terminal of condenser 29 being connected to the lower vertical deflecting plate 8 of the cathoderay tube, whose potential therefore falls from zero to its final value relatively slowly. The beam thereupon is deflected upwards to the left of the column of apertures 6 on plate 1 until it strikes electrode 15. The resulting positive pulse is fed through diode 19 to the grid of the normally cut-off triode 22 and to storage condenser 23. The anode of valve 22 is connected to the upper vertical deflecting plate 7 which receives a negative potential increment to return the beam to the bottom of plate 1 again. This operation is repeated a number of times determined by the voltage applied to the lower plate 8, the charge on condenser 23 and the voltage on the anode of valve 22 and the plate 7 being dependent upon this number. The beam is deflected horizontally across the coder plate 1, after it has reached its vertical position of rest. In another coding tube the apertures in the coding plate 1, Fig. 5, are divided into two parts 80, 82, disposed on either side of a central vertical. zone 81, one of the parts being inverted. The pulse whose amplitude is to be coded deflects the beam upwards in the central zone 81 and the horizontal deflection of the beam to perform the coding is to the left or right according to whether the original time modulated pulse occurred during the first or second half-cycle of a symmetrical saw-tooth oscillation. In a modification, the coding plate differs from that of Fig. 5, the apertures in the right-hand part 82 being reversed from left to right.

Abstract: 1418080 Control systems for discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 May 1973 [9 May 1972 6 Dec 1972 21 March 1973] 21329/73 Heading H2H A system for starting and running a gas discharge lamp comprises a transistor device for superimposing high frequency, high voltage pulses on the alternating supply waveform so as to enhance the starting of the lamp. A low pressure mercury vapour discharge lamp 5 having preheatable electrodes 3, 4 is connected to an A.C. source 1, 2 by way of a ballast inductor 6. The ends of the electrodes 3, 4 remote from the supply terminals 1, 2 are connected to a full wave diode bridge 9-12 across the output terminals 13, 14 of which is connected a transistor 17. A resistor capacitor timing network 19, 20 is also connected across terminals 13, 14 such that as the capacitor 20 reaches a predetermined charge a diac 21 breaks down to render the transistor 17 conducting to cause current to flow through the electrodes 3, 4. The capacitor 20 now discharges whereupon the diac 21 recovers and the transistor 17 goes non-conductive, cutting off current flow in the electrodes 3, 4. The cycle then repeats until the electodes 3, 4 have become heated sufficiently such that the high voltage pulse produced by cutting off the transistor 17 causes ignition of the lamp. The time constant of the circuit 19, 20 is such that the conduction and non-conduction cycle of the transistor 17 is at a frequency considerably higher than the A.C. supply frequency. Simultaneously with the starting operation a second resistor capacitor circuit 23, 24 having a longer time constant than the circuit 19, 20, in charging the capacitor 24 such that when the transistor 22 is rendered conductive to short circuit capacitor 20 the starting operation is terminated. In other embodiments positive and negative temperature coeffieint resistors are used to terminate the starting operation and in which the timing circuit 23, 24 is connected directly to the A.C. source 1, 2 by way of a diode.
