Abstract

394,904. Television. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Jan. 23, 1933, No. 2159. Convention date, Jan. 22, 1932. [Class 40 (iii).] In scanning by a beam of light moving over a series of fixed mirrors F1 .. F5, the scanning lines 1, 2 .. given by one fixed mirror F1 are grouped in the same region, those 7, 8 .. due to a nearby mirror F2 are grouped in a neighbouring region, and so on. The slightly divergent lines, produced by mirrors F1, F5 far apart, are thus at a sufficient distance to prevent the eye from perceiving the lack of parallelism.
