Abstract
Zum Wiederaufbereiten von Fixierflüssigkeiten wird die gebrauch te Fixierflüssigkeit im Kreislauf nacheinander durch einen Filter (2) eine Elektrolysezelle (3) und einen Behäl ter (4) mit vorgegebenem Fassungsvermögen, der mit Einrichtungen (6, 7) zum Zusetzen bestimmter Mengen der die Fixierflüssigkeit bildenden Substanzen versehen ist, hindurchgeleitet. Der mittels des Behälters (4) abgemessenen Menge der Fixierflüssigkeit wird eine Probe entnommen und an einen vom Ort des Fixierbades entfernten Ort übermittelt, wo die Probe analysiert wird. Das Analyse-Ergebnis wird einer elektronischen Datenverarbeitungs- Anordnung (5) zugeführt, die die Einrichtungen (6, 7) veranlaßt, der im Behälter (4) enthaltenen Menge an Fixierflüssigkeit genau diejenigen Mengen an verbrauchten Substanzen zuzusetzen, durch die der Zustand eines frischen Fixierbades wieder herge stellt wird. To reprocess fixative fluids, use fixing fluid in the circuit one after the other Filter (2) an electrolytic cell (3) and a container ter (4) with a given capacity, that with facilities (6, 7) for adding certain amounts of the fixing liquid forming substances is passed through. The means of the container (4) measured amount of the fixing liquid a sample is taken and taken from the location of the fixer remote location where the sample is analyzed. The Analysis result is an electronic data processing Arrangement (5) fed, which causes the devices (6, 7) the amount of fixing liquid contained in the container (4) to add exactly those amounts of consumed substances which restores the condition of a fresh fixer is posed.
