Abstract: 1,010,139. Capacitors. SIEMENS & HALSKE A.G. Sept. 24, 1963 [Sept. 28, 1962], No. 37491/63. Heading H1M. In a wound regenerative capacitor having for at least one electrode a thin metal coating deposited on a surface of a synthetic dielectric material, e.g. polystyrene, polycarbonate, at least the metallized surface of the dielectric is provided with a thin layer of a material whose oxygen and/or hydrogen content is so high that it produces no electrically conductive decomposition products in the vicinity of the perforation when breakdown and regeneration occur. The dielectric film may be coated, prior to vaporization metallizing with a thin layer of a non-aromatic oxygen and hydrogen-rich organic compound by placing the film in vacuo, introducing gaseous or vaporized monomers of the compound to be used, and producing a glow discharge to polymerize the monomers and deposit the polymer on the film surface. Alternatively, oxygen and/or hydrogen atoms or oxygen and/or hydrogen rich radicals may be chemically introduced into the molecular surface of the film by reacting it with oxygen and/or hydrogen or with gaseous or vaporized organic or inorganic hydrogen and/or oxygen rich compounds, e.g. water vapour, in the presence of an electrical discharge, high-energy radiation, e.g. ultra-violet or X-ray, or an electron beam, bombarding the foil. Alternatively, the film may be exposed to a strongly oxidizing atmosphere, e.g. ozone, preferably at high temperatures. The film may be loosely rolled with or without a porous intermediate layer, and may previously be degassed in vacuo. The thin layer may be produced on one or both sides of the film, and it may also be produced on a varnish film produced on a carrier film before metallization and removal for winding into a capacitor.

Abstract: 1390923 Flexible cable ELLIOTT BROS (LONDON) Ltd 15 Nov 1972 [17 Aug 1971] 38523/71 Heading H1A Flexible cable is made by forming conductive strips 2, 3, 4 on a flexible dielectric 1, covering the strip 2 or strips to be used as a signal conductor by dielectric 5, leaving the strips 3, 4 to be used as earth strips exposed, applying, at least initially by chemical plating, a metal screening layer 6 over the whole structure except for termination areas at the cable ends and treating the unplated termination areas to leave some or all of the strips exposed to form termination tabs. By plating on the earth screen a more flexible structure is obtained. Conductors 2, 3, 4, e.g. of copper may be formed on substrate 1 by bonding copper foil to one or both sides of the substrate, e.g. by thermosetting adhesive and etching out the unwanted areas, alternatively strips may be hot rolled or plated through a mask on to the substrate. All the dielectric layers may be of polyethylene terephthalate. Screen 6, e.g. of copper or nickel is preferably formed by an initial chemical plating followed by electroplating to give a thickness of 0-0001 to 0À0005 inches. After plating the assembly may be hot rolled to improve bonding between the screen and its underlying surfaces. The termination tabs may be gold plated. A laquer, e.g. of polyurethane or vinyl may be applied over the screen or a lacquer which has been applied to the screen to protect it against the etchant used to remove the dielectric at the cable ends may be used as permanent protection.
