DEFINITION

Classification: 209/12.1

Plural, diverse separating operations:

(under the class definition) Methods and apparatus involving combinations of different, distinct types of separation operations.

(1) Note. This subclass and the subclasses indented hereunder do not include methods or apparatus which are mere duplications of the same type of separation. Some of the patents which involve sifting and assorting, automatic or manual, have been placed in the assorting subclasses 509-707, and search should be made in such assorting subclasses for such combination. See (7) note of the class definition and subclass 509 definition including the notes appended thereto for the statement of classification control.

(2) Note. The appropriate subclasses providing for the individual types of separations should be searched.

(3) Note. This is the residual subclass for separating combinations not classifiable in one of the subclasses indented hereunder or elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

127.1+, for methods and apparatus employing plural electrostatic charge separating operations.

132+, for methods and apparatus employing both gaseous and liquid suspension of items or materials.

212, for a combination of diamagnetic and paramagnetic magnetic separating methods or apparatus or plural diamagnetic separating methods or apparatus. 214, for plural paramagnetic separating processes.

216, for a plurality of diverse paramagnetic separators.

234, for methods and apparatus employing a plurality of different general types of sifters.

557, for methods and apparatus employing a combination of a condition responsive separating means for either "bulk material" or "special items" and a noncondition responsive separating means. See (1) Note supra.

629+, for combinations of different types of special item separating operations. See (1) Note supra.
