Title: Colour video display apparatus
IPC: H04N9/12
Filed: 1975-05-05
Abstract: 1512062 Colour display system SONY CORP 5 May 1975 [13 May 1974 (2)] 18792/75 Heading H4F A colour video display system comprises (i) a display panel (Fig. 7, not shown) in which cathodes K are arranged perpendicular to anodes A and barrier electrodes B, (ii) a cathode drive circuit 13 which drives the cathodes in synchronism with the horizontal sync pulses of a video signal separated at 10, (iii) signal sampling means 5, 6, 7, 8 for sampling each colour component signal, (iv) means 15, 16 for separating in time each sampling signal to reduce noise and so improve resolution and (v) means 9, 17 for supplying each colour sample signal to respective anodes to produce a colour picture. Horizontal sync pulses S H , Fig. 10F drive a clock pulse generator circuit 14 which produces a number of pulses Sc, Fig. 10G corresponding to the number of anodes A, between successive sync pulses. The clock pulses Sc initiate original sampling pulses Po, Fig. 10H in sampling pulse generator circuit 15 which includes a shift register and both sets of pulses are fed to AND gates 16 so that time separated sampling pulses Ps, Fig. 10I are supplied sequentially to red, green and blue sampling and memory circuits 9 R , 9 G , 9 B  respectively to produce colour video pulses. In this way noise generated by the start and finish of a sampling pulse is not picked up by any other sampling pulse. Alternatively, colour signals SR, SG, SB may be passed through an A-D converter and pulse-code converter before being fed to the sampling circuits. The colour video pulses are sequentially supplied to anodes A so that each pulse causes a discharge between the "on" anode and the "on" cathode i.e. there is a discharge at a point on the display panel so that the colour phosphor PR, PG etc. surrounding the anode at that point glows. The picture is therefore generated as a horizontally shifting sequence of red, green and blue dots. The display panel comprises back and front plates of insulating material, e.g. glass, at least one of which is transparent or semi-transparent, the two plates being sealed at their edges with, for example, frit glass. The plates are separated by insulating ribs which coincide with barrier electrodes (B) which, like the anodes A, may be made from a transparent, conductive material such as Nesa (Registered Trade Mark). The barrier electrodes B are supplied with a constant D.C. voltage to prevent the discharge glow spreading to adjacent cells. Alternatively, liquid crystal or electroluminescent display panels may be used.

Abstract: 1,170,203. Control of A.C. motors; converting circuits. BROWN, BOVERI & CO. Ltd. 23 April, 1968 [25 April, 1967], No. 19037/68. Headings H2F and H2J. A three-phase motor 4 is supplied from a . frequency charger circuit comprising a diode bridge 5, 6, 7, for each phase, and a controlled rectifier 8, 9, 10, shunted across each of the bridges. A supply transformer has secondary windings 1, 2, 3 connected in a cyclic manner to the motor phase windings U, V, W, and the controlled rectifiers are triggered by two pulse trains which have the same frequency but are mutually phase-displaced. The frequency applied to the motor is the difference between the supply frequency and the firing pulse frequency, the direction of rotation being dependant upon which is the greater. If the two frequencies are equal, unidirectional voltage is applied to the motor. The magnitude of the motor voltage is a function of the phase displacement angle. The firing pulses are derived from a generator having a frequency six times the control frequency, the generator being connected to a divider having two outputs in opposite sense and whose frequency is three times the control frequency. The outputs from the divider are applied to an OR gate, one through a pulse shaper, and the other through a pulse shaper and a time delay device. The output from the OR gate is applied to a three-stage ring counter which distributes the triggering pulses to the controlled rectifiers 8, 9, 10, Fig. 3 (not shown); In a modification, the supply transformer has six secondary windings and diode circuits for each phase, Fig. 4 (not shown).
