Abstract

361,496. Electric incandescent lamps. BORNAND, E., 112, Route de Florissant, and SCHLAEPFER, H. A., 13, Rue Verdaine, both in Geneva, Switzerland. Sept. 26, 1930, No. 28836. Convention date, Oct. 4, 1929. Drawings to Specification. [Class 39 (ii).] A body is rendered incandescent by a highfrequency field which is generated by a coil located within the bulb. The body may consist of a metallic sphere coated with a precious metal, or of magnesium, cerium, or thorium oxide which is heated to a temperature at which it is electrically conducting by means of small metallic bodies thereon.
