Abstract

471,825. Television. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 14, 1936, No. 10765. Convention date, April 12, 1935. [Class 40 (iii)] To produce intermeshed scanning, the frame component repeats at frame frequency and the adjacent signals 179, 2, 178, 1 of two groups of line signals at line frequency are separated by angular intervals of one half, or a whole number plus half, of the line frequency. The framing signals are sent separately or by suppressing one or more of the perforations in the disc D, which produces the line signals, Figs. 2 and 2a (not shown). The framing is then produced by an increased electric charge built up by the suppression.
