Abstract
900,537. Capacitors. MANUFACTURE INDEPENDANTE DE CONSTRUCTION RADIO. Feb. 4, 1959 [Feb. 6, 1958; May 21, 1958; July 18, 1958], No. 3994/59. Class 37. A capacitor 1, Fig. 4, is provided with a casing consisting of layers of metal foil, e.g. aluminium, 10a, 10b, alternating with non- metallic layers 11a, 11b of film preferably of a substance such as polystyrol which is capable of shrinking when heated. A strip of metal foil narrower than the film is applied to the film and the composite strip is wound round the capacitor 1. After the sealing plugs 8 have been inserted heat treatment causes the protruding turns 11a, 11b to join together and by shrinking to grip the seals 8. In an alternative arrangement, Fig. 6, the metal foil 10 extends only a little more than one turn round the capacitor 1, while the non-metallic film comprises three turns 6a wound round the capacitor 1 and three outer turns 6b over the metal foil. The metal foil may be provided with printed patterns or other marks visible through the transparent outer layer of film.
