(under subclass 12.1) Methods and apparatus including electrostatic charges for assorting materials by segregating those having certain characteristics from others having different characteristics.
(1) Note. The characteristics may be of weight, size, electroconductivity, hysteresis, etc.
(2) Note. The appropriate subclasses providing for the individual types of separations should be searched.
