Abstract
418,527. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. May 25, 1933, No. 15116. [Class 40 (iii).] To obtain reproduction in colour light filters are mounted in a moving slot 6. The slot 6 in the rotating disc 5 moves over a slot 3 in a mask 4 to form an effective scanning aperture to co-operate with a rotating mirror drum 10. The number of the colour filters corresponds with the number of different component colours used and the disc 5 performs a single revolution while the scanning-drum 10 performs the number of revolutions corresponding to the number of component colours. A source 1 of whitelight is used, and a cell 14 sensitive over a large spectral range or a plurality of cells. The disc 5 may have a plurality of spiral or circular slots, Fig. 2 (not shown). Specifications 321,389, [Class 40 (iii)], and 381,898 are referred to.
