419,485. Batteries. SOC. ANON. LE CARBONE, 37, Rue de Paris, Gennevilliers, Seine, France. Nov. 28, 1933, No. 33353. Convention date, Dec. 5, 1932. [Class 53.] The electrolyte of a dry cell consists of a mixture of an alkali such as caustic soda or potash and a substance such as flour or starch which is capable of being gelatinized by the heat produced by the solution of the alkali in the water which is added to activate the cell. Evaporation and creeping of salts may be diminished by the addition to the dry electrolyte mixture of paraffin wax which melts by the heat produced when water is added, and floats on the top. When the cell cools the wax forms a solid layer over the electrolyte. Sodium chloride may be added to the electrolyte and the electrodes may consist of zinc and carbon. |
