Abstract

A single shaft, carrying flasks e.g. for separation of steroids by partition between highly inflammable solvents, is rocked, pref. through 30 degrees, by compressed air, passed through a valve to a double acting pneumatic piston. The shaft is coupled, when in its operating position, by a lever with a sprung dog clutch to the drive shaft. Swing of shaft is limited by 2 pneumatic reversing switches, operated by a cam on drive shaft. The flasks used are of special desing each comprising a cylinder with a discharge tap at one end, and a central filling funnel, with a bulb enlargement, to limit splashing and vapour loss. Drive system eliminates fire bazard, so that open flasks may be used.
