Abstract

522,476. Variable condensers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., RUST, N. M., BRAILSFORD, J. D., OLIVER, A. L., and RAMSAY, J. F. Nov. 12, 1938, No. 32977. [Class 37] A condenser comprises two electrodes MF<1>, MF<11> each cemented on the outer flat surface of one of two plates AS<1>, AS<11> of semi-conductive material, such as agate, the other surfaces of which are perfect by plane and in contact at PS. A variation in the capacity existing between the plates is effected by subjecting the plates to a variable potential.
