Abstract
803,132. Capacitors. SIEMENS & HALSKE A.G. Oct. 26, 1954 [Dec. 5, 1953], No. 30792/54. Class 37. An electric capacitor comprises a paper dielectric coated on at least one side with a thin aluminium layer so that it is self-healing and impregnated or varnished with a cellulose ester such as cellulose acetate or cellulose butyrate or with a cellulose ether such as ethyl cellulose or benzyl cellulose. It is stated that the cellulose compounds assist in the formation of an oxide film on the aluminium and hence reduce the migration of metallic ions into the dielectric with a consequent reduction in the tendency of the capacitor to break down.
