Abstract

1,171,560. Capacitors. HERCULES Inc. 26 Sept., 1968 [10 Oct., 1967; 6 Dec., 1967], No. 45713/68. Heading H1M. To aid impregnation of a wound capacitor, the non-porous thermoplastic dielectric film, of thickness 0À0002 to 0À0015 inch, is provided with surface irregularities, projections and depressions having a height difference of 0À5 to 10 microns. The dielectric material is preferably one from which oriented films can be produced and may be a polyolefin, vinyl polymer, polyamide, polyester or polycarbonate. The irregularities may be formed on one or both sides of the film by embossing, e.g. with a heated metal rod (Figs. 3, 4, not shown). Alternatively, the uni- or bi-axially oriented film may have heatshrunk portions alternating with unshrunk portions, obtained by means of a roll capable of selective heating, e.g. one comprising a heated wire mesh (Figs. 5, 6, not shown).
