Abstract
240,188. Baradat, C. Sept. 22, 1924, [Convention date]. Kinematograph apparatus.-In continuous-feed apparatus wherein optical compensation is effected by means of a rotating prism having an even number of faces and placed between the objective and the film, the gate and the prism are caused to approach and separate in synchronism with the passage of the images; the apparatus may be arranged to permit direct vision of the images on the film. As shown in Fig. 6, an octagonal prism p is rotated between the gate a and the projection lens o, being geared by wheels d<1>, d<2>, d<3> with a sprocket c for feeding the film. The gate is slidable on rods e and is connected to a crank disc h rotated by the wheel d<2> or the wheel d<3>. Fig. 7 shows an apparatus in which the film is illuminated by means of a mirror b<1> and is viewed bv means of an eye-piece o<2> and reflecting prism o<1>.
