DEFINITION

Classification: 425/6

(under the class definition) Apparatus comprising means dividing or comminuting liquid material to form discrete particles and allowing the liquid to solidify while in particulate form.

(1) Note. Excluded from this and indented subclasses are devices in which the particles are solidified while in contact with a shape imparting surface.

(2) Note. Where the purpose of the comminution is to effect an operation on the material other than that to produce a product of a desired size or shape the patent is not included herein, but will be found in the class providing for said operation.

(3) Note. Included herein is a machine for making cotton candy. The fibers are of indeterminate length and thus are considered particles as opposed to strands or filaments.
