Abstract: A liquid immersion gate for the projection of 35mm motion-picture film is designed to be attached for demonstration purposes to a Model XL Simplex Projector. The frame being projected is held in sharp focus from center to edge in contact with thin layers of methyl chloroform liquid between glass plates. Drift out of focus is thus prevented, resulting in improved sharpness of the projected image. The appearance in the projected image of support scratches on the film is also greatly reduced. The auxiliary equipment required is contained in a separate portable service unit. The liquid used is contained completely in a closed recirculation system except for the escape of vapor to the exhaust pipe. Comparable improvements in image quality could be obtained in many important systems for projection display of film.
