    Abstract: A separator is provided that is particularly suited for separating gases from liquids by selective diffusion through a semipermeable membrane. The membrane forms an enclosure into which diffusate passes and is attached to a flat portion on a surface of a supporting core, so that a strong and leaktight flat seal between the membrane enclosure and the core is formed, with the enclosure interior communicating with a discharge passage in the core. A valve is provided for shutting off flow through the core whenever diffusate flow rate or viscosity exceeds a predetermined maximum.

    Abstract: A flow and/or viscosity indicator is provided having a flowsensing means which is arranged to actuate a signal. A calibrated flow-restricting passage imposes a fluid pressure differential related to flow and/or viscosity across the flow-sensing means, and thus ensures that whenever flow and/or viscosity through the flow-restricting passage changes sufficiently, the change in flow and/or viscosity is reflected in a predetermined change in fluid pressure differential which results in movement of the flowsensing means, in a manner to give the signal. A valve can also be actuated upon movement of the flow-sensing means, for closing off flow through the passage or another line.
