Abstract
A frame and membrane assembly for a liquid transfer cell wherein the frame has a peripheral portion including opposite faces and one face is planar and the opposite face carries a peripherally outer sealing ring and inwardly thereof an anchoring arrangement for the membrane. Most specifically the anchoring arrangement is in the form of a peripheral groove of a generally dovetail cross section with an outer peripheral portion of the membrane being seated within that peripheral groove and retained therein in interlocked relation by way of a continuous second sealing ring. The second sealing ring, when the cell is assembled, is squeezed so as to both more tightly interlock the membrane with the frame and to form an inner seal between the two adjacent frames.
