DEFINITION

Classification: 75/331

Producing solid particulate free metal directly from liquid metal (e.g., liquid comminuting, etc.):

(under subclass 330) Process in which liquid free metal is comminuted to form discrete particles and solidified in its comminuted form.

75, 87, 205, and 921, for processes and non-coating apparatus for growing therein-defined single-crystal of all types of materials, including metals, which are in the form of whiskers.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

5+, for processes of forming solid particulate material directly from molten or liquid mass wherein a material other than metal is comminuted or for processes in which the claims are broad or nondefinitive as to material and the disclosure states that materials other than metal are processed by the invention. Patents having claims to forming solid particulate metal and claims to forming solid particulate nonmetal or patents having generic claims with a disclosure to forming solid particulate metal and to forming solid particulate nonmetal will go as originals to Class 264 and a cross-reference will be placed in Class 75.
