Abstract

321,124. Verschoyle, W. D. Feb. 6,. 1929. Addition to 312,591. Metallic-vapour apparatus.-A lamp as described in the parent Specification is fitted with a series resistance. In the arrangement shown, the capillary tube a is formed with two enlargements c forming mercury reservoirs and an expansion chamber f. Into the reservoirs c through the end portions b of the tube pass tungsten wires d connected to resistance coils g contained in the enlarged ends of the tube and connected to the terminals of a lamp cap k.
