Abstract: A capacitor of hybrid construction is disclosed comprising a single cathode and multiple anode combination utilizing a variety of anode foils selected for their ability to achieve optimal performance in selected areas of the construction of a spiral would capacitor and blended in a fashion to create maximum energy density and minimum open space. In addition, a method is claimed for reducing open space left by a mandrel in producing spiral wound capacitors.

Abstract: A method for making a skinless essentially symmetrical hydrophobic polysulfone microporous membrane by the steps of (a) forming a casting solution containing (i) a dissolved polyethersulfone polymer, (ii) a solvent for the polyethersulfone polymer, and (iii) a lower aliphatic glycol; (b) coating a substrate with the casting composition; (c) exposing the coated substrate to atmospheric conditions; (d) passing the exposed coated substrate into a precipitation bath to precipitate the membrane, the precipitation bath containing a lower aliphatic glycol and water; (e) rinsing the membrane; and (f) drying the membrane.

Abstract: A multiple anode capacitor (10) having offset terminal leads or strips which maximizes capacitance achieved per volume occupied by the capacitor. More specifically, the invention including a multiple anode aluminum electrolytic capacitor including a cylindrical casing (42), a header (45) crimped to the open end of the casing, the header including a primary anode terminal (41) and a primary cathode terminal (44). Disposed within the casing is a wound or coiled capacitor body (28) having plural anode foils (11, 12, 13), a capacitor foil (14), and dielectric paper separator layers (15, 16) disposed between the cathode and the anodes. In a preferred embodiment, three juxtapositioned anode foils are used, the foils being made from a high purity porous aluminum foil. In addition, each of the dielectric paper separator layers is formed of two kraft capacitor tissue papers (15a, 15b, 16a, 16b).
