Abstract
470,608. Electrolytic condensers. MALLORY PATENTS HOLDING CO., Ltd. Dec. 31, 1936, No. 35819. Convention date, Feb. 15. [Class 37] [Also in Group XVI] Electrodes having a part of their surface etched have the other part immunized wholly or partly from the etching operation by applying a layer of protective material such as paper or a film of material such as paraffin. Such an unetched part may form a transverse band as at 11, Fig. 1, a diagonal strip as at 51, Fig. 5, a longitudinal strip as at 41, Fig. 4, or an end portion. A terminal strip may be attached to or, as shown, formed from the unetched part. Fig. 8 shows an apparatus in which the strip electrode 71 is unwound from a roll 70 and successively cleaned in the tank 73, washed in the tanks 77 and 93, etched in the tank 97 and washed in tanks 105 and 109. Between the washings in tanks 77 and 93, the foil passes between felt rollers 82, 83, saturated with suitable immunizing material, which are applied at intervals by means of a cam mechanism 87. As shown, the immunization is effected bv applying an electrolyte by means of the rollers and passing a direct current through the foil as by a generator 91. Specifications 442,646, 453,042, and 35706/36 are referred to.
