Abstract

501,535. Cathode-ray tubes. BAIRD TELEVISION, Ltd., and NUTTALL, T: C. Aug. 31, 1937, No. 23787. [Classes 39 (i) and 40 (iii)] In a tube wherein an electrode 4 upon which an electrostatic image is reproduced by a scanning beam, controls a flooding electron beam to form a luminous image, the flooding beam is produced only during those times when the scanning beam is not incident upon the control electrode to produce charges thereon. In television systems, the scanning time may be reduced to 50 per cent of the line period to obtain a long line for the flooding beam. When the scanning beam is not in operation, other signals, e.g. corresponding to other images, may be transmitted and reproduced in further tubes more especially in colour and stereoscopic systems. The luminous images may be projected onto a screen. The image signals are supplied to the control grid 3 from an amplifier 2. The line frequency component of scanning is effected by means of an oscillator 5, from which pulses are supplied through a shaping circuit 6 to the electrode 3 to change the scanning beam into a flooding beam. Impulses may also be applied from the circuit 6 to the conducting core of the mosaic 4. Specifications 475,047 and 498,824 are referred to.
