Abstract

1321083 Ion-exchange AUTOTROL CORP 9 April 1970 [23 April 1969] 16903/70 Heading B1J The degree of exhaustion of an ion-exchange and hence the concentration of ions in a liquid treated is determined by measuring the volume change in the exchange by means of a moveable sensing element which is moved over measured distances to engage the exchanger.
