DEFINITION

Classification: 205/755

With mixing, agitating, or gas-liquid contacting:

(under subclass 742) Subject matter in which the water, sewage, or other waste water under treatment is (a) mixed, agitated, or otherwise intermingled or (b) contacted with a gas or vapor.

(1) Note. The gas or vapor may either be provided from an external source or be produced during electrolysis, provided that such gas or vapor is clearly disclosed as intentionally contacting the water, sewage, or other waste water. For the purpose of this subclass and the subclasses indented hereunder, such contact is not assumed as an inevitable result of electrolysis and does not provide for the mere liberation of gas or vapor produced thereby.
