Description

Verfahren zur Herstellung von Tonaufzeichnungen auf Linsenrasterfilmen Wenn man auf einem Linsenrasterfilm nach R. Berthon Tonaufzeichnungen anbringen will, so ist der Raster dieses Farbenfilms geeignet, Störungen hervorzurufen. Während bei der Aufnahme Störungen jedenfalls dann nicht zu befürchten sind, wenn die Belichtung des Tonstreifens von der Seite der lichtempfindlichen Schicht aus erfolgt, sind sie bei der Wiedergabe selbst dann zu erwarten, wenn das Beleuchtungssystem sich auf der Seite der Schicht befindet, wenn also die eigentliche Abbildung feiner Spalte nicht einmal gestört wird. Es bilden nämlich die Elementarlinsen stark streuende Systeme, so daß es Schwierigkeiten bietet, das Licht genügend auf die lichtregistrierenden Instrumente zu sammeln. Wenn außerdem der Raster nicht gleichmäßig ist, so entstehen dadurch noch weitere Störungen.Process for making sound recordings on lenticular film When attaching sound recordings to a R. Berthon lenticular film If so, the grid of this color film is suitable for causing disturbances. While In any case, interference is not to be feared when recording if the exposure of the clay strip is made from the side of the photosensitive layer expect them to play back even when the lighting system is turned off located on the side of the layer, so if the actual figure is fine column is not even bothered. This is because the elementary lenses form strongly scattering lenses Systems, so that it offers difficulties, the light enough on the light-registering Collect instruments. In addition, if the grid is not uniform, so arise thereby further disturbances.

Es wurde nun ein einfaches' und sicheres Verfahren zur Beseitigung aller Störungen gefunden. Es besteht darin, durch Überprägen mit einem erhitzten Metallröllchen o. dgl. den Raster in der erforderlichen Breite wieder einzuglätten. Das Einglätten kann während des Perforierens, während der Aufnahme oder in einem besonderen Arbeitsgange erfolgen.It has now become a simple and safe method of removal of all faults found. It consists in stamping over it with a heated one Metal rolls o. The like. To smooth the grid in the required width again. Smoothing can be done during perforation, during recording or in a special operations are carried out.

Durch das ältere Patent 631345 ist ein Linsenrasterfilm geschützt, der einen glatten Längsstreifen für die Tonaufzeichnung aufweist. Über die Herstellung eines solchen Linsenrasterfilms durch nachträgliche Entfernung des Rasters an den für die Tonaufzeichnung bestimmten Stellen kann aus der Beschreibung des Vorpatents nichts entnommen werden.Through the earlier patent 631 345 a lenticular lens film is protected, which has a smooth longitudinal strip for the sound recording. Nothing can be inferred from the description of the prior patent about the production of such a lenticular lens film by subsequent removal of the grid at the points intended for sound recording.
