Abstract
689,556. Etching. STANDARD TELEPHONES & CABLES, Ltd. Nov. 7, 1951, No. 26058/51. Class 100(ii) [Also in Group XXXVI] A coated metal foil, particularly for wound or stack type condensers, is treated to remove portions of the foil not covered by the insulating material. Foil from a reel 1 is cleaned in 4, dried at 5 and coated with insulating material at 6; a suitable material is polythene or polystyrene either molten or in solution; the solvent is driven off by heating at 7 and the coated strip passed through a bath 8 to dissolve away any exposed metal. Nitric acid, hydrochloric acid and sulphuric acid are mentioned as suitable baths, while sodium hydroxide may be used for aluminium and zinc foils; electrolytic baths of copper sulphate, stannous chloride, lead acetate and zinc chloride may be used. The coated foil is washed at 9, 11, dried at 12 and wound together with another coated or uncoated foil 14 to form a condenser. Specification 587,935, [Group XXXVI], is referred to.
