Description
Gerät zum IVlessen der Filmschrumpfung Der Gegenstand der Erfindung betrifft ein Gerät zum Anzeigen der absoluten oder relativen Filmschrumpfung, welches geeignet ist, diese Messungen an einem kontinuierlich laufenden Bildband dauernd vorzunehmen und anzuzeigen.Apparatus for measuring film shrinkage. The object of the invention relates to an apparatus for displaying absolute or relative film shrinkage, which is suitable, these measurements on a continuously running photo tape make and display.
In der Abbildung ist das Gerät schematisch dargestellt. Es besteht :aus zwei Filmrollen i und 2, die durch beliebige Mittel so angetrieben werden, daß säe die gleiche Winkelgeschwindigkeit erhalten. Die eine Filmrolle, beispilsweis:e i, ist ortsfest gelagert, während die andere Filmrolle 2 an einem Lenker 3 befestigt ist, der um einen Stift pendeln kann. Ist das Bildbrand durch Schrumpfen verkürzt, so wird der Normalabstand zwischen den beiden Filmrollen i und 2 verändert. Diese Veränderung übierträgt sich auf den Lenker 3 und auf däs mit ihm verbundene Zeigerwerk 5. An dem Lenker ist ein Einstellorgan vorgesehen, welches die ortsveränderliche Filmrolle zwangsläufig in die Normalstellung zurückführt.The device is shown schematically in the figure. It exists : from two film rolls i and 2, which are driven by any means in such a way, that would receive the same angular velocity. The one roll of film, for example: e i, is mounted in a stationary manner, while the other film roll 2 is attached to a link 3 that can swing around a pen. If the image burn is shortened by shrinking, so the normal distance between the two film rolls i and 2 is changed. These Change is carried over to the handlebar 3 and the pointer mechanism connected to it 5. An adjusting element is provided on the handlebar, which controls the movable Film roll inevitably returns to the normal position.
Die Skala 6 zeigt Marken, welche die Filmschrumpfung entweder in absoluter oder relativer Größe oder in beiden Größen zugleich angeben.The scale 6 shows marks, which the film shrinkage either in absolute or relative size or in both sizes at the same time.
Die Ausnutzung der Längenänderung des Films und deren übertragungsmittel, die hier zum Antrieb der Anzeigevorrichtung dienen, sind zum Antrieb einer selbsttätigen Vorrichtung zum Ausgleichen der Filmschrumpfung bereits Gegenstand des Patents 477 i38.The utilization of the change in length of the film and the transmission means which are provided herein for driving the display device, for driving an automatic device for balancing the film shrinkage already the subject of the patent 477 I38.
