DEFINITION

Classification: 241/38

(under the class definition) Apparatus including, or combined with, means for applying a fluid to the material.

(1) Note. The application of the fluid may occur before, during, or after, the comminution.

(2) Note. The term "means" as used above has been interpreted for the purpose of this classification to include any apparatus including the mill elements themselves, for inducing the flow of a fluid current or any instrumentalities controlling or directing the passage of fluid to or from the material. Devices disclosed for treating solids in fluid suspension, but claiming no "means for applying a fluid" as defined and interpreted above were not classified in this group but will be found in other subclasses on the basis of the claimed combination.

(3) Note. In general this class provides (in this group) the generic place for the combination of a comminutor with means to apply a gas, vapor, or liquid to the solid material being treated, without regard to the nature of the fluid applied or the purpose of the application. Accordingly, the devices found here include comminutors combined with means employing a fluid to heat or cool the material, separate it into grades, convey it, subject it to a chemical reaction, cook the material, etc. Class 34, Drying and Gas or Vapor Contact With Solids, provides the generic place for apparatus, per se, for applying gases or vapors to solids (see the class definition of Class 34 for the line with this class) and Class 134, Cleaning and Liquid Contact With Solids, provides for the generic subject matter, per se, of applying liquids to solid material. For the various special fluid application classes, a study of the notes to the aforementioned two classes should be made.
