Abstract

441,959. Condensers. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Dec. 28, 1934, No. 37185. Convention date, Dec. 28, 1933. [Class 38 (ii)] [See also Groups VIII and XXXVI] A high-frequency condenser for use in short wave radio and similar high-frequency electrical apparatus has a ceramic supporting structure consisting of porous ceramic material which has been rendered substantially non- hygroscopic by impregnation with wax, resin, oil or the like. Ceramic material of as low a specific gravity as 0À5 may be used, and the specific gravity of the supporting structure, even after impregnation, may be as low as 0À8. Reference has been directed by the Comptroller to Specifications 205,547, [Class 95], 309,884, [Class 36], and 367,080.
