[en] 14,493. Brown, B. K., and Brown, T. June 24. Kinematographs.-Reduced kinematograph pictures are formed by photographing with a microscopeon a sensitive structureless emulsion successive pictures of an ordinary kinematograph film. The pictures are taken on a sensitized disk to which motion is imparted so that they are either in spiral form or in concentric rings. The apparatus used is shown in Fig. 1. Rotary motion is imparted to the shaft 1 which through the gearing shown causes a crank 6 to move. the kinematograph film 7 intermittently past the lens of the projecting-apparatus 8. The shaft 11, in which is a slot 12, is also caused to rotate, and by means of a pin 16 on the boss 14 slidingly keyed to it causes intermittent rotation of the Maltese cross 17, which imparts motion to the shaft 20 carrying the sensitized plate 21 and also, through the gearing shown, to the carriage 23 on which it is mounted. By this means, the disk 21 is given an intermittent motion of rotation and translation, and this motion is caused to take place during the motion of the film 7. The pictures are taken by the microscope 22. Apparatus which may be used for viewing the pictures is shown in Fig. 4 and is similar to the apparatus described above, excepting that the microscope 41 is given a longitudinal motion and the disk 21 only a rotary motion.
