Description

Verfahren zur Herstellung von Kinofilmen zur gleichzeitigen Wiedergabe von Bildern und Tönen. Das Verfahren besteht darin, daß ein Filmnegativ kopiert wird, auf welchem Gesichts-und Gehöreindrücke in gemeinschaftlicher photographischer Kammer optisch festgehalten sind. Während der Bildteil photographisch in bekannter Weise behandelt wird, wird die belichtete Leimschicht an den Stellen der Klangschrift nach dem Entwickeln und Fixieren durch Gerbung in einem geeigneten Gerbebad ätzfest gemacht. Unter dem Schutze der gehärteten Emulsion wird dann der Schichtträger an den nicht belichteten Stellen angeätzt oder bis zu einem gewissen Grade gelöst. Besteht der Schichtträger aus Zellhorn, so ist das Lösemittel z. B. Azeton. Im Löseprozeß bildet sich im Schichtträger nach Maßgabe des Klangbildes die Klangfurche, die von einer Schallabnahmevorrichtung bespielt wird. Der Verwendung photomechanisch verwertbarer, zellhornähnlicher Stoffe (Gummi, Kollodium u. dgl.) steht nichts im Wege; stets kommt es darauf an, daß die Schallfurche im Schichtträger in der beschriebenen Weise unter dem Schutze der gehärteten Emulsion, die ätzfest ,decken muß, durch Ätzung oder teilweise Lösung des Schichtträgers in dem für ihn geeigneten Lösemittel entsteht.Process for the production of motion picture films for simultaneous playback of images and sounds. The process is that a film negative is copied is on what facial and auditory impressions in communal photographic Chamber are optically held. While the picture part photographically in well-known Wise treated, the exposed glue layer is at the points of the sound script after developing and fixing by tanning in a suitable tanning bath, it is etch-proof made. Under the protection of the hardened emulsion, the support is then applied the unexposed areas are etched or dissolved to a certain extent. If the substrate is made of cellular horn, the solvent is e.g. B. acetone. In the solving process The sound groove is formed in the layer substrate according to the sound pattern, which is caused by a sound pickup device is recorded. The use of photomechanically usable, Nothing stands in the way of cell-horn-like substances (rubber, collodion, etc.); always it is important that the sound groove in the layer support in the manner described under the protection of the hardened emulsion, which must be etch-proof, cover by etching or partial solution of the substrate in the solvent suitable for it is formed.

Gegenüber dem bekannten photomechanischen Verfahren der Herstellung von Schallfurchen auf metallischen Unterlagen nach Art der Erzeugung von Druckstöcken (Britisches Patent 7I5/I9oI) bietet die beschriebene Ätzung nichtmetallischer, zellhornartiger oder zellhornähnlicher Stoffe den Vorteil, daß der gemeinsame Bild- und Schallfilm gemäß der Erfindung in einem einzigen, ununterbrochenen Vorgang aufgenommen, kopiert und geätzt werden kann, was die Verwendung metallischer Schichtträger ausschließt. Dabei ist zu beachten, daß die metallische Ätzung der Tiefe nach einem körnigen, für das Schallabnahmewerkzeug ungeeigneten Boden ergibt, was bei der Ätzung von Zellhorn oder zellhornähnlichen StoEen nicht der Fall ist.Compared to the known photomechanical method of manufacture of sound grooves on metallic substrates in the manner of printing blocks (British Patent 715 / 19oI) provides the described etching of non-metallic, cellular horn-like or cellular horn-like substances have the advantage that the joint image and sound film recorded according to the invention in a single, uninterrupted process, copied and can be etched, which excludes the use of metallic substrates. It should be noted that the metallic etching of the depth after a grainy, results in unsuitable soil for the sound absorption tool, which is caused by the etching of Cell horn or cell horn-like substances is not the case.

PATENTANSPRUCH: Verfahren zur Herstellung von Kinofilmen zur gleichzeitigen Wiedergabe von Bildern und -Tönen, wobei die Aufnahme von Bild und Schall in der photographischen Kammer gleichzeitig erfolgt, dadurch gekennzeichnet, daß der Träger der nach dem Filmnegativ hergestellten photographischen Bildschicht unter dem Schutze der an den Klangschriftstellen gehärteten und ätzfest deckenden Emulsion angeätzt oder gelöst wird, so daß nach Maßgabe des Schallbildes die Schallschrift in Furchen auf den Schichtträger entsteht.PATENT CLAIM: Process for the production of cinema films for the simultaneous Playback of images and sounds, with the inclusion of images and sound in the photographic chamber takes place simultaneously, characterized in that the carrier the photographic image layer produced after the film negative under the protection etched to the hardened and etch-proof covering emulsion at the points of the sound script or is solved, so that according to the sound image the sound writing in furrows arises on the substrate.
