Abstract
1,086,348. Capacitors. E. I. DU PONT DE NEMOURS & CO. June 24, 1966, No. 28447/66. Heading HIM. In a capacitor comprising pairs of metal foils separated by dielectric strips convolutely wound and immersed in a dielectric fluid, defects due to irregular contact between the foil strips and dielectric strips are minimized by coating the dielectric strips on both sides with metal. As shown, electrodes 21 and 22, staggered to protrude from the eventual roll in known fashion, are separated by dielectric layers 23 and 24 coated with metallized layers 25 and 27, and 26 and 28, respectively. Opposite edges on opposite sides of the dielectric strips are left unmetallized as shown at 29 and 30 by screening techniques or removal of the excess. The dielectric layers may be polyethylene terephthalate, polycarbonate, polyolefin, fluorinated polymers or paper. The electrodes and metallizing may be aluminium, zinc or copper. The roll may be immersed in mineral oil or so-called electronegative gases.
