DEFINITION

Classification: 210/787

Cyclonic, or centrifugal (e.g., whirling or helical motion or by vortex, etc.):

(under subclass 767) Process wherein the influent flows tangentially of a container in a manner to produce a whirling motion or there is an agitator to rotate the influent to form a vacuum at its center.

SEE OR SEARCH THIS CLASS, SUBCLASS:

304, for apparatus including a filter in which there is a spiral or convolute baffle or tangential liquid inlet to give the liquid a whirling motion.

512, for apparatus wherein fluid flows tangentially to produce a whirling motion or there is driven means to rotate the fluid.
