Abstract

541,550. Nitrogenizing. GENERAL ELECTRIC CO., Ltd., CLACK, B. N., and RANSLEY, C. E. May 29, 1940, No. 9425. [Class 72] [Also in Group XL] In a cathode glow lamp wherein the filling is a mixture of nitrogen with a rare gas the electrodes are of iron or other metal coated with a layer of nitride. The coating may be effected by heating the electrode in ammonia at 600‹C. Specification 210,728, [Class 39 (i)], is referred to.
