Abstract
574,596. Variable condensers. ASHLEY ACCESSORIES, Ltd., and KEMPSTER, W. P. Feb. 5, 1944, No. 2158. [Class 37] A condenser has the electrode in the form of a metallic coating 7 on the upper surface of a rotary plate 4 of, for example, ceramic material, the lower surface being ground flat and moving on the similarly ground upper surface of a ceramic &c. base plate 1 on the under side of which the co-acting metallic surface 10 is deposited. The metallic coating on the rotary disc is integrally united as by soldering to the means for its adjustment, such as a screw-driver nicked spindle 5. The latter may have a protecting disc 11. In a modification the lower plate also houses a detachable partially-coated disc to alter the range of capacities obtainable with the condenser.
