DEFINITION

Classification: 96/171

And tangential flow or centrifugal separating means:

(under subclass 168) Apparatus (a) which is also provided with means for tangential fluid flow (e.g., having an inlet or outlet arranged for directing fluid flow about a central axis, etc.) or (b) in which means are provided to separate entrained gas from the liquid under treatment by centrifugal force, causing the gas and liquid to rotate about a central axis which forces degasified liquid to move away from the axis and separated gas to move toward the axis of rotation.
