SU29717A1 - Cinematographic apparatus for continuous projection with opaque filmstrip - Google Patents

Description

In cinema printsrat, in which the projection is based on reflection and not on translucency, Izhroka was used not to perforate ropes, paper made of polished paper, which, in the opinion of the inventor, will reduce the cost of the process and will make it possible to use objectives of greater luminosity.

In FIG. 1 shows the apparatus in schematic form; FIG. 2- a device for advancing cinema and tape in a perspective view; FIG. 3- part of the apparatus.

In the proposed cinematographic apparatus, the envelope of the roller, of the film /, /, is mounted on the ends of the rods 7, which are driven by connecting rods from the crank 9 on the gear wheel to advance the belt (, /), and the pressure pads 35 are used for the same purpose. , 36, articulated with levers 37, 38.

To press the tape to the base of the rear window, the pads 5, b, the schichlenee // races with levers 12, /. Are supported, supported by their rollers 17, & Nor eccentric disk 7 /, mounted on the axis of the gears.

. On the same axis, the worm gear or gear 22 is mounted to rotate the rod 2, from which j

To support the levers / 3. / J Roller axles of the rollers jV and .5, which support the film on the roller. Roller 2 is covered with a rubber plate a half (Fig. 3), and Protakmppets are two frames-one in motion and the other in reverse.

The rays of light of codensor 27 and 2L are on the prisms 29 and SO, and from the mch and the frames pressed by the decks 5 and from here the reflections of the illuminated cluster come back to these points. after receiving a full internal fi eld: co :: ie, they fall into the S / and 5 prilmy.
