Abstract

375,658. Synchronous movements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Stocker, A. C. ; 1, Park Place, Audubon, New Jersey, U.S.A.) Oct. 20, 1931, No. 29142. Convention date, Oct. 21, 1930. [Classes 40 (iii) and 40 (v).] To reduce the effect of transients on the synchronization of television and copying- telegraph receivers, the synchronizing signals are divided into a plurality of parts by a transformer 8, one part is displaced in phase a whole number of cycles by a network 15, 16, and the parts are recombined by a transformer 11. The other part is passed through resistances 17, 18 to produce an attenuation equal to that of the first part.
