Abstract

426,126. Light-sensitive cells. LEMON, C. G., 19, Lena Gardens, Hammersmith, and KECSKEMETI, L., 1, Cygnet House, King's Road, Chelsea, both in London. Oct. 11, 1933, No. 28305 /32. [Class 40 (iii)] A light - sensitive device, for reproducing photographic sound records, comprises metal electrodes a in the form of segments of a cylinder assembled to form a complete cylinder and separated by a thin layer of insulating material, the light-sensitive material c being applied between the linear edges of the segments at one end of the cylinder. The cell is held by a screw e in a holder d which is provided with a transparent cover f. In a modified arrangement, Fig. 3, two cells are formed in a holder d by separate electrodes a<1>, a<2>, associated with a common electrode a<3>.
