Abstract
525,791. Television ; cathode-ray tubes. BAIRD TELEVISION, Ltd., and TOMES, G. A. R. March 1, 1939, No. 6673. [Classes 39 (i) and 40 (iii)] In apparatus for producing rolling cuts, fades &c. an electron beam modulated by image signals is caused to fall on an electrode system having areas of different secondary emission ratio, the image signal in the output circuit being dependent on the area on which the beam is incident. The electrode system 3 may be of nickel on which a design may be produced in carbon, as in Fig. 2. The secondary electrons are collected on anode 4, and the output taken at terminal 7. As the beam is moved slowly from position 8 through 9 to 10, a blackout passes across the reconstituted picture. Two electron guns 11, 12, Fig. 3, may produce beams scanning lines on a drum 13 on which suitable designs are produced as in Fig. 2, and for fading &c. the drum may be rotated by armature 16 and a magnet 17 external to the tube.
