Abstract

169,324. Wade, H., (Concordia Elektrizitats Akt.-Ges.). July 13, 1920. Absorbents; cells; electrodes; electrolytes; supports for electrodes. -In electric handlamps, particularly for miners' use, the accumulator receptacle a is made of metal and is provided with a lead lining b into which fits the hollow negative electrode d, the positive electrode' e being situated within the negative electrode and suspended by a central pole-piece from the cover c. The accumulator is first charged when containing a liquid electrolyte, which is then replaced by a solid one, such as a mixture of sulphuric acid and water glass. Specification 24443/95 is referred to.
