204, Chemistry: Electrical and Wave Energy, particularly
155+, for the production of a compound or element by chemical reaction brought about by electrical or wave energy in a
magnetic field; subclasses 157.15+ for processes of treating materials involving a chemical reaction brought about by wave energy; and subclasses 554+ for magnetic treatment, per se, when some effect other than mere separation is desired or produced or for simultaneous electrical and magnetic liquid separation which does not result in the production of a compound or element by chemical reaction brought about by electrical or wave energy in a magnetic field.
209, Classifying, Separating, and Assorting Solids, 29, for a process of separating solids while in a fluid suspension.
