Abstract
1,084,500. Discharge lamps. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 28, 1965 [Dec. 31, 1964], No. 54907/65. Heading H1D. [Also in Division F4] A mercury vapour fluorescent lamp has one of its ends sealed by a glass stem which extends into the lamp and has deposited on it a metal which forms an amalgam with mercury. A lamp (1, Fig. 1, not shown), in a photocopying machine, having indium (21) deposited on one or both glass stems (14) which support the electrodes (15), is mounted with its central portion within the reflector (4) of the housing (2) and its end portions in the cooler end compartments of the housing. The lamp ends are supported by engagement of the terminal pins (17) in the sockets (22).
