Abstract
1527. Johnson, J. Y., [Badische Anilin and Soda Fabrik]. Jan. 20. Arc lamps. - A long and stable arc is maintained between carbon electrodes in a transparent tube by a current of air or other gas, with or without rotary motion, and is rendered luminous by matter contained in the electrodes or carried by the gas current. The arc should be surrounded over its whole length by a cool layer of the air or gas, which may be introduced at several points of the tube. The electrodes are surrounded by heat - conducting metal sheaths which may be cooled in any suitable manner and which approach as nearly as possible the arcing surface, at which point they may be flanged, as shown in Fig. 1, or flared. Such arcs may be used for photographic purposes, or for testing the fastness of colouring-matters, on account of their richness in ultra-violet rays. Specifications 14,955/05 and 9279/06 are referred to.
