zu sein braucht.
Man kann natürlich auch die Vorkehrung treffen, dass einige Walzen sich in um- gekehrten und andere Walzon sich in gleichem Sinne wie das Papier drehen, um auf das Papier keinen allzu starken Zug in entgegengesetztem Sinne zu seiner Bewegungsrichtung auszuüben.

gekrümmte Form, welche es annimmt, gesichert wird. Die von einem geeigneten Reservoir kommende Flussigkeit wird dem'obersten Behälter B durch ein Rohr F zugefübrt nnd aus diesem Behälter gelangt sie mittels Überlaufbrunnen G der Reihe nach zu den unteren Behältern, um schliesslich in einem Sammotbottich Bi aufgefangen zu werden.
Wie ersichtlich, gestattet dieser Apparat mit einer sehr geringen Flüssigkeitsmenge und nach Wunsch mit Bädern verschiedener Natur in den verschiedenen Behältern B zu arbeiten.
Wenn im vorhergehenden von empfindlicher Fläche die Rede ist, so ist dieser Ausdruck ganz allgemein aufzufassen. Handelt es sich beispielsweise um das Tonen, durch welches den fertigen Bildern ein anderer Ton gegeben werden soll, so kann man, genau genommen, nicht mehr von einer empfindlichen Fläche sprechen. Gemeint ist stets die Fläche, welche mit der durch die photochemische Einwirkung noch nicht reduzierten oder bereits reduzierten empfindlichen Schicht bedeckt ist.
PATENT-ANSPRÜCHE : 1. Verfahren zum Entwickeln, Fixieren, Waschen, Tonen oder sonstiger chemischer Behandlung von photographischen Bändern, bei welchem das Papierband mit seiner empfindlichen Fläche Über mit dem Bade getränkte Walzen hinweggeführt wird, dadurch gekennzeichnet, dass die Tränlnvalzen mit einer grösseren Geschwindigkeit als die des fortbewegten Papierbandes angetrieben werden.

needs to be.
Of course, you can also take the precaution that some rollers turn in the opposite direction and other rollers turn in the same direction as the paper, so that the paper is not subjected to excessive tension in the opposite direction to its direction of movement.

curved shape it assumes is secured. The liquid coming from a suitable reservoir is fed to the uppermost container B through a pipe F and from this container it reaches the lower containers one after the other by means of an overflow well G, where it is finally collected in a collecting tub Bi.
As can be seen, this apparatus makes it possible to work with a very small amount of liquid and, if desired, with baths of different types in the various tanks B.
When speaking of a sensitive surface above, this expression is to be understood in a very general way. For example, if toning is used to give the finished images a different tone, then, strictly speaking, one can no longer speak of a sensitive surface. What is always meant is the area which is covered by the sensitive layer that has not yet been reduced or has already been reduced by the photochemical action.
PATENT CLAIMS: 1. Process for developing, fixing, washing, toning or other chemical treatment of photographic tapes, in which the paper tape with its sensitive surface is guided over rollers soaked with the bath, characterized in that the soaking rollers are carried out at a greater speed than that of the advancing paper tape.
