Abstract

351,468. Light-sensitive cells. CONSTABLE, F. H., St. John's, Cashio Lane, Letchworth, Hertfordshire, and RADIOVISOR PARENT, Ltd., 26, Coventry Street, London. March 24, 1930, No. 9423. [Class 40 (iii).] In a cell having a light - sensitive layer r mounted upon a base, the latter is formed of opaque glass to prevent the incidence of light upon the light-sensitive material from the rear and sides of the cell base. Where a primary cell is employed with a compensating cell, e.g. to compensate for temperature changes, the operative and compensating areas may be mounted on a common base of opaque glass and the secondary cell completely shielded from the influence of light. In the compensated cell, Fig. 1, the primary and compensating areas A, B are mounted on a common base of opaque glass, and the portion B is further shielded by an opaque glass screen D. Alternatively the whole cell may be covered by one or more sheets of mica of which the lower portion, corresponding to the area B, is blackened. The composite cell is held in U- shaped clips E, F, G, connected to electrodes M, L, K, and may be additionally supported by springs, Fig. 1a (not shown). The secondary cell may be further shielded by an extension of the clip E to cover the whole surface B. Fig. 4 shows the operative cell A mounted independently of the compensating cell B completely enclosed between its opaque base O, and an opaque strip P with distance pieces Q, R. The compensating cell, suitably insulated, may be enclosed in a light-tight metal box, or in a light-tight casing in which the members P, O, Q, R are constructed of vulcanite or slate.
