Abstract

1306556 Semi permeable membranes BAXTER LABORATORIES Inc 15 May 1970 [16 May 1969] 23789/70 Heading B1X A flexible semi-permeable membrane 10 and a separately formed stiff backing 18 are arranged face to face being folded along lines of weakness 20 in the backing to define two sets of pockets at opposite faces of the membrane which are closed at ends 52 and 54 to define a flow path at each face of the membrane for the respective fluids. Flow dividers (not shown) may be inserted in the folds.
