7897. Dupuis, C. April 10, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Kinematographs.-A single positive film, Fig. 2, has juxtaposed small images, the stereoscopic couples being projected by a single lens on to a translucid screen combined with a stereoscope for individual observation. The film is obtained by employing two ordinary negatives in a double kinematograph, Fig. 4, the slides which guide the films being eccentrically arranged relatively to the lenses so as to produce simultaneous registering of the two series, each of which covers half the available film width. The two negatives are then impressed on a single positive.
