Description

Die Erfindung betrifft einen Kolorimeter mit für sich getrennt einstellbaren Tauchbechern. Bei den bisher bekannten Kolorimetern dieser Art mußte der für jeden Tauchbecher eingestellte Wert für sich abgelesen werden, und es mußte dann durch eine Rechnung der Endwert ermittelt werden, der die gesuchte Konzentration der zu untersuchenden Flüssigkeit ergab. Diese Ausrechnung erforderte nicht nur erhebliche Zeit, sondern war auch eine unerwünschte Fehlerquelle. The invention relates to a colorimeter with separately adjustable colorimeters Diving cups. With the previously known colorimeters of this type, it was necessary for everyone Dip cup set value can be read for itself, and it then had to go through a calculation of the final value can be determined, which is the concentration of the to be sought investigating liquid revealed. This calculation not only required considerable amounts Time, but was also an undesirable source of error.

Gemäß der Erfindung vermeidet man diesen Mangel dadurch, daß die Bewegungseinrichtung für die Tauchbecher je mit einer nach einer logarithmischen Kurve geformten Kurvenscheibe od. dgl. verbunden ist, die über ein Differential ihre Bewegungen auf ein Meßgerät für den Endwert zwangsläufig übertragen. According to the invention, this deficiency is avoided in that the Movement device for the dipping cup each with one after a logarithmic Curve shaped cam or the like. Connected via a differential inevitably transmit their movements to a measuring device for the final value.

Es fällt also gegenüber den bekannten Konstruktionen jede nachträgliche Schreib- und Rechenarbeit, die Fehler enthalten können, fort. Compared to the known constructions, there is no subsequent one Writing and arithmetic work that may contain errors continue.

Desgleichen fallen auch alle weiteren Einstell-und Ablesefehler fort, da nur nach Einstellen auf Gleichheit noch der Endwert abgelesen wird und alIe Zwischenrechntmgen die Vorrichtung ausführt. Likewise, all other setting and reading errors are eliminated, because the final value and all interim calculations are only read after setting to equality the device executes.

In der Zeichnung ist ein Ausführungsbeispiel für einen Kolorimeter gemäß der Erfindung schematisch dargestellt. Die Handräder I und 2 dienen einerseits zur Verstellung der Tauchbecher (nicht dargestellt) in der Höhe, andererseits zur Bewegung je einer Kurvenscheibe 1a, 2a Diese Kurvenscheiben verschieben die Zahnstangen 3 und 4. Durch die Zahnstangen werden Ritzel 5 und 6 und über diese das Differential 7 bzw. der Differentialkäfig 8 gedreht. Mit dem Differentialkäfig 8 ist das Zahnrad g verbunden, welches über das Zahnrad IO das Meßgerät II auf den Endwert einstellt, der von diesem ohne weiteres ablesbar ist. In the drawing is an embodiment of a colorimeter shown schematically according to the invention. The handwheels I and 2 serve on the one hand for adjusting the dipping cup (not shown) in height, on the other hand for Movement of one cam disc 1a, 2a each. These cam discs move the racks 3 and 4. The racks become pinions 5 and 6 and through these the differential 7 or the differential cage 8 rotated. With the differential cage 8 is the gear g connected, which sets the measuring device II to the final value via the gear wheel IO, which can be easily read from this.
