Abstract
694,676. Electric condensers. STEPHEN, R. A. March 17, 1952 [March 20, 1951], No. 6639/51. Class 37. A condenser is made by rolling together on a mandrel a strip of thermoplastic dielectric material with foil electrodes, and heating the assembly so that the thermoplastic material flows over the edges of the foils to seal them together. A polystyrene strip 4, Fig. 2 is inserted in a slot 15, Fig. 4 in a mandrel and wound with foils 2, 3 as shown in Fig. 2. Instead of foils, the strip may be coated with aluminium, tin, silver or carbon. The condenser is placed in a holder 11, Fig. 3, and the portion 8 of the dielectric strip is cut away, the mandrel 7 removed and replaced by a mandrel 14. The assembly is then heated to cause the polystyrene to flow over the ends, and the mandrel removed. The mandrel 12 may be of steel, but if the condenser is not to have a central aperture, the mandrel 12 may be of plastic material and is left as a central core.
