Abstract

16,937. K÷rting & Mathiesen Akt.- Ges. Dec. 27, 1911, [Convention date]. Arc lamps.-A reflector for a search-light, in which electrodes emitting fumes are used, is kept clean by an air-blast passing over its surface, for example from its lower edge or from its centre. In the latter case, a flat box perforated circumferentially may be supplied with compressed air by a pipe in front of the reflectors ; or jets from a pipe 3 carried through the reflector may be directed by a cap 5.
