Brief Description of Patent: This invention is for improvements in or relating to cinematograph projectors of the colour-projection type in which two or more complementary picture-images representing several colour components of this scene to be depicted are projected on to the screen simultaneously through a corresponding number of lenses so that the picture-images on the screen are superposed on one another and combine to form a picture in colours, and in which an obturating shutter is provided which is common to all lenses and oburates them all simultaneously. Condition: Slight crinkling. Note: See also listing for patent 324,060. Cinematograph Projectors. This patent specification has been disbound from a volume of 100 different patents. This is an original HMSO published item at the time, not a modern copy as are being sold elsewhere. The drawings are often ideal for framing. It is part of a collection of several volumes from the 1920/30's that I have from which individual patents will be sold over the next few months.
