Methods and means under Magnetic for separating components of material by magnetic repulsion.
(1) Note. This subclass includes cases where the repulsion is due to inherent diamagnetism and cases where it is due to magnetic polarity established by electrical currents (eddy or Foucault currents) developed in conductive components.
SEE OR SEARCH THIS CLASS, SUBCLASS:
12.1+, particularly subclasses 38-40, for diamagnetic separation combined with other separating operations classifiable in this class (Class 209).
562, for a magnetic means delaying actuation of a means separating special items.
567+, for a magnetic test sensing a property of special items to be sorted.
639, for means sorting special items by use of a magnet.
SEE OR SEARCH CLASS 204, Chemistry: Electrical and Wave Energy,
554+, for electrical (e.g., electrostatic, etc.) or simultaneous electrical and magnetic separation or purification of liquids or magnetic treatment of liquids (other than separation) and subclasses 660+ for corresponding apparatus.
210, Liquid Purification or Separation,
222+, for processes and apparatus for applying a magnetic field to a liquid to separate particles therefrom for the disclosed purpose of clarifying the liquid.
588, Hazardous or Toxic Waste Destruction or Containment, appropriate subclasses using magnetic force in destroying or containing hazardous or toxic waste.
