752,321. Batteries. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. Nov. 4, 1954 [Nov. 4, 1953; Oct. 5, 1954], No. 31945/54. Class 53. A deferred action cell comprises a casing 1 divided by a frangible partition 2 into two compartments one of which contains the electrodes 10, the other containing the electrolyte 4. The casing is closed by a flexible membrane 3 which may be of rubber. When the cell is required for use the membrane 3 is given a blow which is transmitted by the electrolyte to the partition 2 which is thereby broken. One or more perforated plungers 7 having a serrated lower edge may be secured to the membrane 3 to transmit the pressure to the diaphragm which may be supported by a rigid member 18 having openings 19 below the plungers 7. The partition 2 may be of ebonite or glass or of stretched rubber and the electrodes and separators may be provided with channels 5 below the plungers to facilitate permeation of the cell by the electrolyte. Electrodes of the same polarity are joined together by screws 12, 14 carrying terminal lugs 13, 15. The electrolyte is introduced into the upper compartment through an opening 16 which is then closed by a plug 17. |
