Abstract
208,071. Tacey, R. G. H., Stobart, P., and Skee, W. A. April 5, 1923. No Patent granted (Sealing fee not paid). Kinematograph apparatus.-In a projector, reflecting surfaces are provided on the usual shutter, or on an additional revolving carrier between the shutter and the lens, and are so disposed as to reflect the whole or part of the light rays back to the lens. As shown, the shutter comprises a rim a attached by radial arms b to a central disc c, and has opaque, semi-opaque, or coloured sectors f and open sectors g. Mirrors j are clipped or otherwise fastened to the arms b and may be plane or slightly concave. Alternatively, the arms b may be made of reflecting material. The mirrors may be all in one plane or some may be in the plane of the shutter and others in two planes respectively nearer to and farther from the lens.
