Title: Cinematographic apparatus
IPC: G03B1/56
Filed: 1949-02-08
Abstract: 663,387. Kinematograph apparatus. PAILLARD SOC. ANON. Feb. 8, 1949 [April 1, 1948], No. 3417/49. Class 97 (i) A kinematographic apparatus includes a device for restoring automatically the length of the film loop between the film gate and a continuously rotated film sprocket, said device including a loop restoring member which is normally held out of engagement with the film and is adapted to come into contact with the moving film and be rotated thereby when, for any reason, the length of said loop decreases, and means co-operating with said member during the rotation thereof so as to import a translating motion thereto. The kinematograph apparatus shown comprises a sprocket 3 for continuously feeding a film to a film gate 5 and a sprocket 7, for continuously moving the film away from the gate 5, through which the film is intermittently fed by a claw feed mechanism (not shown). Between the gate 5 and sprocket 7 is mounted loop restoring member in the form of a sprocket 13 having attached thereto a cam 15. The sprocket and cam are rotatably mounted on a stud 12 carried by a lever 10 which is pivoted to a frame 1 . at 11 and is spring urged at 17 so that the cam 15 contacts a projection 16 from the frame. When the length of the film loop formed between the gate 5 and sprocket 7 decreases, the film meshes with the teeth of sprocket 12 so that the latter is rotated. The consequent rotation of cam 15 thus causes the stud 12 to move in an arc of a circle having its centre at 11. The film loop thus increases and reaches its correct length after a half revolution of the sprocket whereupon the cam 13 is again in its rest position shown. The projection 16 may be carried by a pivoted and spring urged lever. In the form shown in Fig. 6, the sprocket 13 may be carried by a stud 12 slidable within a straight slat 21 in the frame 1 and spring connected to a fixed stud on the frame so that the sprocket stud is normally at the upper end of the slat and is moved downwardly when the sprocket rotates by the action of a cam 15 and a fixed projection 16. Alternatively, the sprocket may have a cog wheel attached thereto, said wheel meshing with a rack disposed parallel to said slat, so that the stud moves in the slot when the sprocket rotates. Other forms are described wherein (a) a lever hinged to the frame 1 and to the sprocket causes the movement of the sprocket stud in the said slot ; (b) the sprocket is rotatably mounted on a spring-urged lever pivoted to frame 1 and a rod is hinged to the frame and the sprocket ; (c) the sprocket is rotatably mounted on a spring-urged and pivoted lever and carries a projecting stud which rides on the surface of a fixed cam and (d) the sprocket and a drum attached thereto are mounted on a lever pivoted to the frame and an elastic band connects the drum to the frame.

Ice-making, plate apparatus for; agitating water to be frozen.-In plate apparatus for ice-making, of the type described in Specification 21357/10, the tank containing the slabs or plates 5 and the water to be frozen is formed by the sides of an outer metal tank 1, end walls 2 spaced from the ends of the outer tank, and a false bottom 4. Thawing-off water circulates through the bottom space 7 and the end spaces 3 thus formed, and the slabs or plates 5 next to the sides of the outer tank are spaced from the sides sufficiently to prevent the water from freezing on to the sides of the tank, thus avoiding the necessity for thawing-off at the sides. The branches 13, 14 connecting the freezing-pipes in the plates with the main supply and return pipes 19, 22 are arranged at the ends of the plates to avoid damage when the blocks of ice are lifted. To split the blocks into sections when thawing-off, hollow division-pieces 9 open at the top and communicating with the space 7 are fitted between the plates as shown. The hot water rises in the division-pieces and at the ends 3. During the freezing operation, shutters 23 are fitted over the tops of the spaces 3, and air is drawn through the division-pieces 9 and space 7 and passed to the usual agitator, without special cooling, through an opening 24, Fig. 1. Valves 25, 17 are provided for the supply and discharge of hot gas for thawing-off.
