A New Transparent Rotary Shutter
This is a description of a new form of rotary shutter for intermittent motion picture projection apparatus. The idea is based on the principle of optical admixture of the three primary colors or of a complementary pair in order to produce the sensation of white. Scientific application of the above principle has resulted in increased screen illumination and decided reduction of flicker. The theory involved and its practical application are fully dealt with by the author.
