DEFINITION

Classification: 209/713

Mechanically induced swirling:

(under subclass 143) Methods and apparatus wherein a movable member creates a rotary stream to promote deposition of

entrained or suspended material from the gaseous suspension due to resultant centrifugal or centripetal forces.

(1) Note. The preceding subclasses which involve gaseous suspension and deposition should be searched for the separation of entrained or suspended material subjected to a suspending and classifying action of an impinging gaseous current or a combination therewith.

(2) Note. A fan, impeller or pump for the sole purpose of creating the material entrained or suspended current and not for effecting deflection to create the rotary stream is not proper for classification in this or the subclass indented hereunder. Such mechanical element, external to the separating means, is classifiable with the fluidically induced separation means of subclasses 711+ when employed in combination with a plurality of interconnected separation means or in an appropriate subclass subsequent hereto.

SEE OR SEARCH THIS CLASS, SUBCLASS:

710, for a combination of plural rotary stream creating separating phases including a separating phase having a movable member.

715+, see (2) note supra. SEE OR SEARCH CLASS

55, Gas Separation, appropriate subclasses for indiscriminate removal of entrained or suspended material; particularly,

400+, for a gas separation device including a movable means for assisting in removal of a constituent of a gaseous material flow; and subclasses 437+ for a gas separation device including means for effecting the gas flow. See (3) Note in Class 209 subclass 132.

95, Gas Separation: Processes,

270, for a gas separation process involving mechanical deflection to create a swirling motion. See (3) Note in Class 209 subclass 132.

210, Liquid Purification or Separation,

787+, for processes and subclass 512.3 for apparatus for indiscriminate removal of entrained or suspended material from a liquid suspension analogous hereto.
