Title: Improvements in and relating to picture transmission systems
IPC: H01J31/32
Filed: 1946-05-17
Abstract: 616,306. Picture transmission systems. SCOPHONY, Ltd., and WIKKENHAUSER. C. May 17, 1946, No. 15040. [Class 40 (iii)] In a picture transmission system an electrostatic image of an object is formed on an image plate during a short exposure and scanned during a time longer than the exposure time. An optical image of an object 1, Fig. 1, is formed on the signal mosaic plate 3 of a picture signal generating tube 4 during a short exposure time determined by a shutter device 5 produces an electrostatic image which, due to the mutual insulation of the mosaic elements, persists for a time after the exposure sufficient to produce picture signals when the plate 3 is subsequently scanned by an electron beam at a rate which may be several times longer than that of a normal television frame scan. By making the scanning speed sufficiently low high definition pictures may be transmitted in a comparatively narrow frequency band. The system may be used for the transmission of " stills " of moving objects and it is stated that blurring of such objects may be overcome by suitable adjustment of the exposure time. Frame scanning signals are produced by the circuit of Fig. 2 (not shown), in which a condenser charged through a resistor supplies a frame deflection potential which at the end of a complete frame scan deflects the beam beyond the picture area until the condenser becomes fully charged. A switch is provided for discharging the condenser and initiating a further frame scanning cycle, the line scanning generator being maintained in continuous operation. Further embodiments using picture signal generating tubes of the " super-iconoscope " and " image orthicon " types are described with reference respectively, to Figs. 3 and 4 (not shown).

Title: Improvements in or relating to pulse generating systems
IPC: G06F1/10
Filed: 1952-06-25
Abstract: 714,746. Pulse circuits. COMPAGNIE DES MACHINES BULL. June 24, 1952 [July 6, 1951; Dec. 27,1951], No. 15887/52. Class 40 (6) A pulse generating system receives periodical pilot pulses forming a rectangular wave, whose pulse rate is T/n, through a control channel and distributes n different pulse trains to n output channels, the pulse trains having the same period of recurrence T, the same duty cycle and are respectively delayed to one of them by times T<SP>1</SP>/n 2T/n n-1/n T respectively. Figs. 7-8 show a system for generating trains of pulses as shown at B1, B2, B3, B4, Fig. 1, from a master timing pulse train P, Fig. 1, a schematic of the system being shown in Fig. 6. The system comprises four pulse generators A1 ... A4 each of which comprises, as shown in connection with generator A3 of Fig. 8, a pentode valve 38 which has a postive feedback circuit from anode to control-grid via transformer 50 and negative feedback by a network in the cathode circuit. An input pulse train B3, Fig. 1, is applied at input d3 the individual pulses of which are limited between the voltages -V5 and +V4 and an input pulse train B3 is applied at input f3 similarly limited ; the master timing pulse train from generator 16, Fig. 7, being applied at input e3. Thus initially the inputs d3 and e3 are at a level of -V5 and input f3 at level +V4 and as these two former inputs are applied to the coincidence gate 63, Fig. 8, comprising rectifiers 63a, 63b point 39 will be approximately at a potential of -V5 and terminal 65 at +V4, and pentode 38 thus normally conducts. When a pulse is received from generator 16 at input e3 this is passed through gate 63 if the voltage at input d3 from unit A2 is approximately at a voltage +V4 and the control-grid voltage of pentode 38 changes from -V5 to +V4 so that the anode voltage at point 47 falls to a value intermediate its minimum and maximum values +V3 and +Vl, so that it is unlikely that generators A2 and A3 will emit a pulse simultaneously at the start of the operation. If a pulse is produced in one of the generators A2 or A3 when the first pulse of train P, Fig. 1, is received then the inputs b and c of generator A1 will both be at -V5 white input e will be at +V4 so that due to the action of gate 86 comprising rectifier 86a, b and c the control grid of valve 85 will remain at -V5 so that no pulse from generator 16 is sent to input d2 of generator A2. If, however, two timing pulses originate simultaneously in generators A1 and A4, on receipt of the first pulse of train P, Fig. 1, the first 'pulse of train B1 is terminated after an interval 3t (i.e. twice the delay of each network 24, 25 or 32) and voltage -V5 appearing simultaneously at inputs e4 and f4 of generator A4 cause impulse B4, Fig. 1, to cease. Thus each generator is controlled by the input pulse train applied at its inputs d, e and f, the winding 50b of transformer 50 being in reverse direction to those of the other windings 50a, c and d.
