Abstract

347,435. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Smith, T. A. ; 20, Heights Road, Ridgewood, New Jersey, U.S.A.) March 29, 1930, No. 10087. Convention date, April 1, 1929. [Class 40 (iii).] In systems in which the direction of scanning alternates between two directions making an angle with each other, the two directions are obtained by means of a single scanning member alternately co-operating with one of two fixed projecting systems. The scanning member 1, Figs. 1 and 2, consists of a mirror disc, one half of which cooperates with fixed mirrors 17, 21, Fig. 1, to completely scan the screen 25 in a direction 27, while the mirrors of the other half co-operate with a fixed mirror 31, Fig. 2, to completely scan the screen in a direction 35. A lens 11 focuses light from a varying source 9 upon the mirrors. A lens disc or drum may be used in place of the mirror disc 1.
