Die Hauptpatentanmeldung Z10436IXb/42d (deutsche Auslegeschrift 1266 989) beschreibt eine Einrichtung zur Interpolation von Meßwerten, die von Längen- oder Winkelmeßgeräten geliefert werden, bei der zur digitalen Interpolation von periodischen Signalfolgen ein Signalgeber vorgesehen ist, der über getrennte Ausgänge um 90° gegeneinander phasenverschobene, vorzugsweise sinusförmige Signale liefert und bei der die Ausgänge des Signalgebers an die Ablenksysteme einer Kathodenstrahl- ίο röhre angeschlossen sind, so daß der Elektronenstrahl pro Signalfolge einmal auf einer geschlossenen Umlaufbahn umläuft und bei der zur Unterteilung der Umlaufbahn oder eines Bildes derselben Rasterelemente vorgesehen sind.The main patent application Z10436IXb / 42d (German Auslegeschrift 1266 989) describes a device for the interpolation of measured values, the are supplied by length or angle measuring devices, in the case of the digital interpolation of periodic Signal sequences a signal generator is provided, which via separate outputs at 90 ° to each other supplies phase-shifted, preferably sinusoidal signals and in which the outputs of the signal generator are connected to the deflection systems of a cathode ray tube, so that the electron beam per signal sequence circulates once in a closed orbit and in the case of the subdivision the orbit or an image of the same grid elements are provided.

Aufgabe der vorliegenden Erfindung ist es, diese Einrichtung in einem Meßgerät zu verwenden, das es gestattet, Interpolationen in verschiedenen Maßsystemen durchzuführen, z. B. im Zentimetersystem und gleichzeitig im Zollsystem.The object of the present invention is to use this device in a measuring device which it allows interpolations to be carried out in different systems of measurement, e.g. B. in the centimeter system and at the same time in the customs system.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Interpolationsraster auswechselbar sind und ihre Rasterkonstante ein ganzzahliges Vielfaches der kleinsten Maßeinheit in jedem der Maßsysteme ist.This object is achieved according to the invention in that the interpolation grids are exchangeable and their grid constant is an integer multiple of the smallest unit of measurement in each of the systems of measurement is.

Liefert bei dieser Ausbildung der Maßstab ζ. Β. 0,1 Zollschritte, dann ergeben sich bei Verwendung eines Rasters mit 100 Interpolationsschritten V1000-Zoll-Meßeinheiten. Bei Verwendung eines Rasters mit 254 Interpolationsschritten erhält man von ein und demselben Ausgangsmaßstab die V100 mm als kleinste Meßeinheit.In this training, the standard ζ delivers. Β. 0.1 inch steps, then result when using a grid with 100 interpolation steps V1000 inch units. When using a grid with 254 interpolation steps, the V100 mm is obtained from one and the same starting scale as smallest unit of measurement.

Die Rasterauswechslung kann dadurch erfolgen, daß die Röhre gegen eine andere mit einem anderen Raster oder Rastersystem austauschbar ist. Dies kann aber auch dadurch geschehen, daß dann, wenn der umlaufende Elektronenstrahl durch optische Mittel auf ein Raster abgebildet wird, dieses Raster auswechselbar ist. Dies kann aber auch dadurch geschehen, daß in der Röhre mehrere konzentrisch angeordnete Raster vorgesehen sind, von denen je eines eine bestimmte Interpolation vermittelt und daß man, um Meßwerte in dem einen oder anderen Maßsystem zu erhalten, die Grundspannung des umlaufenden Elektronenstrahles ändert, so daß dieser sich auf einer Kreisbahn mit entsprechend geändertem Radius bewegt und das zugeordnete Raster überstreicht.The grid replacement can be done in that the tube against another with another Grid or grid system is interchangeable. But this can also happen that when the rotating electron beam is imaged on a grid by optical means, this grid is interchangeable is. But this can also be done in that several concentrically arranged in the tube Grids are provided, one of which each conveys a certain interpolation and that one, in order to obtain measured values in one or the other system of measurement, the basic voltage of the rotating Electron beam changes so that it is on a circular path with a correspondingly changed radius moves and sweeps over the assigned grid.

In der Zeichnung ist eine Rasteranordnung für den letztgenannten Fall dargestellt.The drawing shows a grid arrangement for the latter case.

Es sind zwei konzentrisch angeordnete Raster 1 und 2 vorgesehen, von denen das erst Raster 254 Stege und Lücken aufweist, das Raster 2 dagegen MeßeinrichtungThere are two concentrically arranged grids 1 and 2, of which the first grid 254 webs and gaps, the grid 2, however, measuring device

Meßwerte in Vioo mm Zählschritten. Das Raster 2 dagegen liefert Viooo Zoll. Die Bahn 3 des Elektronenstrahles wird durch Spannungsänderung entweder auf das Raster 1 oder das Raster 2 gelegt.only 100. If the output pulses are tapped from a 0.1 inch scale, then the delivers over The electron beam sweeping the grid 1 with one revolution 254 counting units, d. H. Measured values in Vioo mm counting steps. The grid 2, on the other hand, provides Viooo inches. The path 3 of the electron beam is placed either on grid 1 or grid 2 by changing the voltage.
