DEFINITION

Classification: 34/60

(under the class definition) Apparatus claiming diverse means for performing two or more diverse treating operations on material undergoing treatment. At least one must be either (1) drying or (2) gas or vapor contact with solids. Treating operations are operations designed to change characteristics of the solid material. Means for feeding, discharging, conveying, agitating, testing or other ancillary operations on the material, which operations do not change the characteristics of the material, are not, of course, included in this group.

(1) Note. This subclass has the combination of lamps to apply light energy within or outside of the visible spectrum. Complete the search in this class, subclasses 266+, and see the notes thereto.

(2) Note. This subclass and the indented subclasses do not include plural apparatus of the same kind for performing plural drying and/or gas or vapor contact operations of the same type on the solids even though the units are referred to by different names as steaming and drying chambers. Such plural units, stage operations, plural chambers, etc., are with the subclasses appropriate to the type of apparatus. See Note (4) in subclass 209 of this class.

(3) Note. This subclass and indented subclasses do not include single vacuum type apparatus. See the search notes below.

(4) Note. For processes for performing diverse operations, see the search notes below.

(5) Note. Apparatus providing for treatment of the gas or vapor applied to the solids for treatment, or evolved from the solids, is in this class, subclasses 72+.

(6) Note. See Note (2) to Lines With Other Classes in the class definition of this class for drying and/or gas or vapor contact apparatus for performing other operations provided for in other classes. SEE OR SEARCH THIS CLASS, SUBCLASS:

92, for single vacuum type apparatus.

418+, for processes for performing diverse operations.
