Abstract
660,473. Condensers. STEPHAN, F. C., DOWNEY, D. P., and WEGO CONDENSER CO., Ltd. Feb. 8, 1950 [Feb. 9, 1949], No. 3545/49. Class 37. A capacitor has an active part 2 including electrodes, e.g. foil 5, spaced by one or more layers of organic material, e.g. paper, a protective enclosure 1 consisting wholly or partly of a synthetic resin which sets at least at temperatures below 100� C., and anchoring means, e.g. metal end caps 7, rigidly connected to terminals 3 projecting from the enclosure 1 to which the caps 7 are bonded. A strong air and moisture proof seal is thus provided. The terminals 3 are soldered both to the caps 7 and to wire spirals or metal discs 6 soldered to the foil ends 5. Flanges 8 are provided on the caps 7 to facilitate bonding. The resin comprises an unsaturated polyester of a dibasic aliphatic acid, cast or moulded about the part 2. In making the condensers, the part 2 is placed on a spacer lying in the base of a mould, a top part of the mould is placed in position, and the liquid resin poured in. The spacer then becomes bonded to the casing 1. Alternatively open moulds may be used, or an injection moulding process employed.
