Abstract
421,256. Photo - electric cells. PRESSLER, M. A. E., 98, Elisenstrasse, Leipsic, Germany. March 14, 1933, No. 7752. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 15, 1933]. [Class 39 (i)] The foundation for a light-sensitive layer is formed with a "spongy-velvety" surface, for example, by a coarse flaky deposit, or by depositing metal electrolytically in spongy form. The surface is subsequently oxidized and treated with alkali metal vapour, and the cell is filled with gas.
