Abstract
8144. Campbell, J. April 7. Kinematograph ap. paratus. - In colour kinematography of the kind in which two or more films are exposed or projected in alternate order by means of two or more lenses and through two or more stationary colour screens, two shutters are employed exposing alternate pictures in twocolour work, Fig. 2; and in three-colour work two shutters are employed, one being a doubleopening shutter and exposing two out of every three pictures, Fig. 3. The openings in the shutter may be of such a size as to give equal or unequal exposures to the different colour series.
