The flow rate of weak cell liquor is determined, using a device in the form of a small box having in one wall thereof a properly sized orifice, a vertically extending slot thereabove, and a rule placed alongside the slot to make it possible to read the flow rate. A cooperating member is provided to catch the liquid passing through the device and disperse it into a plurality of small droplets while feeding it to a trough by which the weak cell liquor is collected.

Device for measuring flow of weak cell liquor

There is used a structure modified so that the brine-introduction tube is mounted within a larger-diameter tube sealingly mounted in the brine-introduction opening in the side of the cell top, with an orifice member preferably being mounted within an end of the brine-introduction tube nearer to the cell. This makes it possible to avoid unwanted variations in the brine flow rate and to see instantly whether an orifice member is clogged.

A cell frame for a bipolar electrolytic filter press cell includes an electrolysis-associated lower section and a gas disengagement or diverting upper section. A pressure bar extends across the cell frame immediately above the lower section to prevent distortion of the separator by cathode generated gases, and to promote disengagement of the gases. The frame, also, includes external headers in the upper section for collection of the gases evolved by the electrolysis of the electrolytic solutions.

An end connector for a filter press cell disassociates the mechanical sealing function from the primary electrical connection. The connector includes a boss extension having an aperture formed therein for tightening the connector between the boss and boss extension. The present invention is adaptable for use as an end connector for either the anode or the cathode.

Segmented electrodes for use in electrolytic filter press cells obviate and reduce the problems of current distributions attributable to poor bipolar electrical connections, and electrode flatness. The electrodes are supported on the electrical boss as well as on the central barrier.
