Description

Verfahren zur gleichzeitigen Aufnahme und Wiedergabe von Lichtbildern und Schallwellen. Zusatz zum Patent 358848. Die Erfindung betrifft eine weitere Ausbildung und Abänderung des Verfahrens zum Zweck, die Lautstärke bei der Wiedergabe der Schallwellen beliebig erhöhen und die Positivfilme in ider bisher gebräuchlichen Form, d. h. mit einer lichtempfindlichen Gelatineschicht, verwenden zu können.Process for the simultaneous recording and reproduction of photographs and sound waves. Addendum to Patent 358848. The invention relates to another Training and modification of the procedure for the purpose of increasing the volume during playback Increase the sound waves at will and the positive films in the same way as previously used Shape, d. H. with a light-sensitive gelatin layer.

Das Aufnahmeverfahren wird dabei unverändert beibehalten, der Negativfilm wird mit seinen Lichtbildern und mit Aden in Form von Strichen festgehaltenen Schalllwellen auf :einem normalen Positivfilm kopiert, dies geschieht zweckmäßig nicht wie bisher meistenteils üblich ruckweise, sondern, wie an sich bekannt, mit stetiger Fortschaltung der Filme durch einen schmalen Spalt hindurch.The recording process is retained unchanged, the negative film becomes with his photographs and with aden recorded sound waves in the form of lines on: copied from a normal positive film, this does not happen as before mostly usual in jerks, but, as is known, with continuous progression of the films through a narrow gap.

Der erhaltene Positivfilm wird entwickelt, fixiert und getrocknet. Sodann wird auf die Gelatineschichtseite eine zweite schmale Gelatineschicht aufgespritzt, die nur so breit zu sein braucht, daß sie die Schallwellenbilder vollkommen deckt. Die Dicke dieser aufgespritzten Schicht läßt sich,durch die Konzentration der Gelafiinelösung und durch die Geschwindigkeit des dabei gleichmäßig bewegten Positivfilms regeln. Der ganze Positivfilm wird nunmehr in Kalium- oder Ammoniumbichromat getaucht und nach dem Trocknen dem Licht längere Zeit ausgesetzt, und zwar in der Weise, d@aß der Film mit der Schichtseite nach unten auf eine Trommel aufgewickelt wird. , Durch die Einwirkung des Lichtes wird zuerst die auf dem Positivfilm gleichmäßig verteilte Schicht (primäre Schicht) vollständig gegerbt, die zweite schmale (sekundäre Schicht) hingegen nur dem Schallwellenbild entsprechend, d. h. die dunklen Stellen weniger, die hellen Stellen mehr. Der Film wird sodann in heißes Wasser eingetaucht. Hierbei werden die Lichtbilder bzw. die ganze primäre Schicht nicht angegriffen, weil sie durch das Licht vollständig gegerbt wurden, während aus der sekundären :Schicht die dunklen Stellen mehr oder weniger aufgelöst werden, so daß ein Relief der Schallwellen entsteht, welches sehr scharf den Strichen der Schallwellenbilder angepaßt ist, weil die sekundäre Schicht auf den Schal:lwellenbildern unmittelbar aufliegt.The positive film obtained is developed, fixed and dried. Then a second narrow gelatin layer is sprayed onto the gelatin layer side, which only needs to be so wide that it completely covers the sound wave images. The thickness of this sprayed-on layer can be determined by the concentration of the gelatin solution and regulate it by the speed of the positive film, which is moving evenly. The entire positive film is now immersed in potassium or ammonium dichromate and exposed to light for a long time after drying, in the manner that d @ ate the film is wound face down on a drum. , By the effect of light is first that evenly distributed on the positive film Layer (primary layer) fully tanned, the second narrow (secondary layer) on the other hand only according to the sound wave pattern, d. H. the dark places less, the light spots more. The film is then immersed in hot water. Here the photos or the entire primary layer are not attacked because they fully tanned by the light, while from the secondary: layer the dark areas are more or less resolved, so that a relief of the sound waves arises, which is very sharply adapted to the lines of the sound wave images, because the secondary layer rests directly on the scarf wave images.
