Abstract
213,373. Parsons, Sir C. A. Jan. 27 1923. Drawings to Specification. Mounting electric lamps in lanterns.-In order to preserve the concentration of the projected beam of light in the vertical direction when the reflector of a searchlight is elastically deformed, the source of light is moved slightly closer to the reflector by independent means or by means coupled to the screws employed for deforming the reflector. Specifications 5001/96 and 16599/07 are referred to.
