Abstract

1,218,931. Metal-vapour lamps. RCA CORPORATION. 18 March, 1968 [31 March, 1967], No. 12984/68. Heading H1D. [Also in Divisions G3 and H2] A D.C. operated mercury arc lamp, comprising an outer glass envelope and a fused quartz inner envelope, has associated with it a voltage and current regulating circuit (see Division G3). This circuit may be built into the neck of the lamp, which is also provided with a starting electrode.
