Abstract
966,538. Capacitors. SIEMENS & HALSKE A.G. Aug. 15, 1962 [Aug. 24, 1961], No. 31262/62. Drawings to Specification. Heading H1M. A capacitor formed from metal layers alternately separated by two different thicknesses of dielectric, the dielectric consisting of varnish layers, has the metal layers vaporized on to those varnish layers which form the or part of the thicker layer of the intervening dielectric. In a method of making such a capacitor a first composite strip is prepared by applying a varnish layer to a paper strip, then vapour depositing an aluminium layer on the varnish layer and applying a further varnish layer on the aluminium layer. The two varnish layers and the aluminium layer are stripped from the paper to provide the composite strip required. A second composite strip is prepared similarly, but need only combine the aluminium layer with one varnish layer. The two composite strips are wound together into a roll with the metal layer of the second strip against the second varnish layer of the first strip, the thickness of this varnish layer being less than that of the combined thickness of the varnish layer of the second strip and the first varnish layer of the first strip. An alternative method using a more complicated second composite strip but constructed similarly is also described. The object of the arrangement is to provide a capacitor which has a high specific capacitance per unit volume.
