Abstract

373,540. Television. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, France. Nov. 10, 1931, No. 31152. Convention date, Nov. 26, 1930. Addition to 373,539. [Class 40 (iii).] In an exploring system, a beam of light is moved over a plurality of groups M1, M2, M3 of fixed mirrors by an oscil.. lating mirror, lens L, or prism. The mirrors of the last group M3 are con.. cave to increase the convergency of the beam. According to a modi.. fication the initial oscillating motion is produced by movement of the light source by a variable electric or magnetic field acting on a rarefied-gas column.
