    Abstract: A self-valving fluid reservoir and bubble trap for a fluid flow line is disclosed which comprises a tubular conduit carrying a transverse, flow-blocking partition in the conduit flow path. The conduit defines upstream and downstream lateral ports on each side of the partition to permit fluid communication between the interior and exterior of the conduit. A flexible, expansible and collapsible, sealed reservoir chamber is mounted on the conduit to enclose the lateral ports. The chamber receives excess fluid in the flow line by expansion, but collapses against and occludes the downstream port or ports in the absence of excess fluid in the reservoir chamber.

    Abstract: A MASS TRANSFER DEVICE IS MADE BY WINDING A HOLLOW TUBULAR CONDUIT OF SEMI-PERMEABLE MEMBRANE ABOUT A CORE TO FORM A MULTILAYER WINDING OF THE CONDUIT IN WHICH INDIVIDUAL ADJACENT WINDINGS IN THE SAME LAYER ARE GENERALLY PARALLEL TO EACH OTHER, BUT INDIVIDUAL ADJACENT WNDINGS OF THE CONDUIT IN ADJACENTS LAYERS DEFINE AN ANGLE TO EACH OTHER. THE ENDS OF THE CORE TRANSVERSE TO THE TUBULAR CONDUIT WINDINGS ARE THEN POTTED WITH A CURABLE SEALANT. AFTER CURE OF THE SEALANT, THE ENDS OF THE WOUND CORE ARE CUT TRANSVERSELY THROUGH MEDIAL PORTIONS OF THE CURED SEALANT TO SEVVER THE CONDUIT INTO A PLURALITY OF INDIVIDUAL CONDUIT SECTIOBS, THE RESULTING SECTIONS BEING SECURED TOGETHER AT THEIR ENDS BY PORTIONS OF THE CURED SEALANT, AND HAVING THEIR HOLLOW BORES OPEN TO THE EXTERIOR. MANIFOLDS ARE THEN APPLIED TO PROVIDE ONE FLUID FLOW PATH PASSING THROUGH THE HOLLOW BORES OF THE CONDUIT PORTIONS AND ANOTHER FLUID

    FLOW PATH PERCOLATING BETWEEN THE EXTERIORS OF THE CONDUIT PORTIONS.
