Abstract

987,313. Capacitors. TELEPHONE MANUFACTURING CO. Ltd. Jan. 7, 1964 [Jan. 16, 1963], No. 1951/63. Heading H1M. A spiral strip capacitor is wound on a hollow core or a mandrel sleeve of axial length exceeding the width of the wound strip and of heat softenable or shrinkable material; the ends of the core or sleeve being subsequently heat treated by infra red radiation or a jet of hot gas to fuse or shrink and seal off the bore of such core or sleeve. The material may be biaxially oriented polystyrene or polyethyleneterephthalate film; or longitudinally oriented polycarbonate film wound on to a mandrel, and a stiffening layer of polyethyleneterephthalate sheet or paper may be incorporated in the sleeve; being of narrower width and centrally positioned to define the ends of the sealed sleeve or core.
