SU33814A1 - Table for the installation of sound films - Google Patents

Description

In the process of producing sound films, in the case when the phonogram is taken separately from the film, an operation called editing is necessary. The latter consists in that the director or the person in charge of compiling the final copy of the tape looks at and selects the appropriate pieces of photographic and phono recordings, combines and mutually synchronizes them. This operation, carried out with the help of a projector and a sound-reproducing installation, is very laborious and, if there is no appropriate equipment, it is very difficult. In order to simplify this operation, there are so-called assembly tables, the operation on which makes it possible to see and hear this segment of the film and manipulate it more comfortably than with a normal installation of two projectors.

The purpose of the present design is to further improve such a mounting table.

In FIG. 1 shows a side view of the table in longitudinal section; FIG. 2 is the same, top view.

The proposed table for the installation of sound films consists of a system of two windings 6-6 and 7-7, a mechanism 2 for pulling a tape with images

and a mechanism 3 for pulling a tape with a phonogram. System 6-6 serves to lay the phonogram, and system 7-7 photo-recordings. The mechanisms 3 and 2 receive rotation from the common shaft 10 of the motor 4 and are connected not directly, but through a differential mechanism /. Such a device makes it possible to perform the following operations: skip photo and audio recordings and on the move, by rotating the differential box 7 in one direction or the other, synchronize both recordings, and since the speed change will occur on the projector, the sound will not be disturbed. You can also, by stopping the motor 4 and holding the mechanism 2, drag the soundtrack to the desired mark, or hold the mechanism 3, drag the photo recording or view it by individual frames, or. finally, having linked the shafts 10 and 12, to move, turning the knob 5, both recordings in one direction or the other to the required place. All of the above operations make the editing of the sound film very easy.

The subject matter of the invention.

A table for mounting sound films, equipped with projection and sound-producing devices, characterized in that mechanism 2 for pulling a tape with images and mechanism 5 for pulling a tape with a phonogram are interconnected by a drive shaft 70 through a differential mechanism / for mutual synchronization of both tapes and the possibility of independent movement of one of them relative to another.
