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 660+ for a liquid treatment apparatus which is specialized for: magnetic treatment, per se, when some effect other than mere separation is desired or produced or simultaneous electrical and magnetic separation of the liquid 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,
38, 39, 40, 212, 213+, and 478 for processes and apparatus involving applying a magnetic field to material (which may be suspended in a liquid) for the purpose of separating one solid component from another.
