Note(s) This subclass covers the making of metallic powder only insofar as powder with specific physical characteristics is made. [6] In this subclass, the following terms or expressions are used with the meanings indicated: "metallic powder" covers powders containing a substantial proportion of non-metallic material; "powder" includes somewhat larger particles which are worked, obtained or behave in a manner similar to powder, e.g. fibres.
