Abstract

137,613. Tyson, W. F., Baker, J. C., and Rutter, J. Jan. 25, 1919. Kinematograph apparatus.-A rotating disk shutter has a radial slot C between concentric slots D in one masking-blade B, and concentric slots E between apertures F, which may be shaded, in the other blade B'. This arrangement may be modified by putting the concentric slots on the blade B and the apertures F on the blade B' in the centre of the blades, and the other slots are then placed at each side.
