Abstract
186,781. Wade, H., (Concordia Elektrizitats Akt.-Ges.). Aug. 19, 1921. Connections; cells. -In miners' electric lamps the battery tar minale i, k are arranged concentrically in the centre of the lamp and are separated by an insulating sleeve j. The battery is closed by a cover g and packing-rings secured by a spring ring h engaged in a groove in the casing. B o t h battery electrodes may be connected directly to the terminals as shown, or the outer electrode may be connected electrically to the terminal k through the outer casing and the cover g
