IPC: H01M6/38
Abstract: 133,707. Portable Electric Current Patents Co., (Assignees of Apostoloff, S.). Oct. 10, 1918, [Convention date]. Electrodes.-The carbon and zinc electrodes 14, 13 and the paste electrolyte 18 of a dry cell are kept apart until the cell is required for use, when the upper portion 11 of the cardboard casing 11, 12 is removed and the zinc electrode 13 pushed down into the casing 12, thereby breaking a wax film 36 normally covering the electrolyte, and causing the electrolyte to fill the space between the electrodes. The terminal screws 21, 22 of the electrodes pass through openings in the top of the casing and are provided with nuts whereby the electrodes are supported above the electrolyte. The zinc electrode 13 is formed with a vertical slot 13a, as shown in Fig. 1, terminating in a horizontal portion 13b and a vertical portion 13<c> at the top and engaging a fixed stud 40 on the portion 12 of the casing. The electrode is closed at the upper end by a pitch sealing 25<b>, an absorbent layer 30 of Kieselguhr, and paper washers 29, 31. The carbon rod 14 and depolarizer 15 are contained in a porous wrapping 16 surrounded by bands 17 and closed by layers of wax 33, 35. The bands 17 may be of rubber &c. or of zinc, in which case they form the negative electrode, the electrode 13 being then dispensed with. In a modification, only the carbon electrode is fixed to the upper portion of the outer casing, the zinc electrode being closed at the bottom and containing the electrolyte which is brought into contact with the carbon by an upward movement of the zinc electrode after the lower portion of the outer casing has been removed. The terminals in this form are at opposite ends of the cell. The electrolyte is made by dissolving ammonium chloride &c. in water, adding powdered cellite or Kieselguhr and 7¢ to 11 per cent of agar-agar emulsified with 1/10 part by weight of glycerine or " still bottoms." Starch or flour &c. may be substituted for the agar-agar, in which case the mixture is heated to 82‹ C. The Specification as open to inspection under Sect. 91 (3) (a) describes a form of cell in which the electrolyte is contained in a zinc cup within the casing 12, the groove 13 in the electrode being engaged by a pin projecting from the zinc cup. This subject-matter does not appear in the Specification as accepted.
