Abstract

484,319. Multiple filament electric lamps. BETHKE, E. F. J. A. Nov. 30, 1936, No. 32757. Convention date, Nov. 30, 1935. [Class 39 (ii)] A multiple-filament lamp with a gas-filling containing krypton or xenon, or both, is provided, either within the bulb or cap, with a separate fuse for each filament. The filaments may each have a separate pair of leading-in wires, with a fuse incorporated in each wire, or there may be a common return wire which is not provided with a fuse. The filament may be of different wattages and in the form of plain helices, or double-coiled or multiple - coiled helices, and may be arranged in any suitable manner, for example one above another or in a plane at right-angles to the axis of the bulb. A suitable filling consists of 15 parts of xenon to 100 parts of krypton, to which other rare gas or gases or nitrogen may be added.
