Abstract

1283. Accumulatoren - Fabrik Akt.- Ges. April 15, 1913, [Convention date]. Drawings to Specification. Thermometers.-In a device for detecting the presence of methane or other inflammable gases in air by means of glowing catalytic conductors heated from an exterior source, a number of heated conductors are employed so that the number which become luminous serves as an indication of the quantity of inflammable gas present.
