Abstract

249,713. Morgenstern, W. June 18, 1925. No Patent granted (Sealing fee not paid). Phosphorescence and fluorescence, apparatus for lighting by.-A luminous disc for use as an emergency light consists of a convex disc b mounted in a frame c and painted on the back with a luminous paint, such as a radio-active substance or a phosphorescent material mixed in some cases with colouring material. The coating a is covered with a material d, such as gypsum paste, which protects paint against weather and prevents passage of luminous rays, and a disc e is fixed at the back.
