Abstract

424,743. Television receivers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 2, 1934, No. 13283. Convention date, May 2, 1933. [Class 40 (iii)] A television system for reproduction in colour employs a number of cathode-ray tubes, corresponding to the number of colours into which the view is analyzed, which are adapted to reproduce alternate lines of the image transmitted. Images reproduced by the cathode ray tubes 1, 2, corresponding to red and green in alternate lines of the view being transmitted are associated with red and green filters 10, 11 and are simultaneously observed by means of a partially silvered mirror 9. Instead of using filters 10, 11 the ends of the tubes 1, 2 may be coated with materials which produce red and green fluorescence, respectively. The rays are traversed over their screens by a single saw-tooth wave form, the bias on the corresponding deflecting plates of the two tubes being such that the ray is swept across one screen by the lower half of the wave, whilst the second screen is traversed under the action of the upper part of the saw-tooth wave.
