(under subclass 422) Apparatus including supports for material associated with magnets which so operate as to apparently increase or decrease the specific gravity of magnetically-influenced constituents, so that said magnetically-influenced constituents will settle downward into a stratum as if they were the heaviest constituents when the magnetic pull is downward or will move into an upper stratum when the magnetic pull is upward.
(1) Note. The distinction between this subclass and the magnetic separator subclasses ante is that in this subclass the magnets merely assist in the stratifying the material and the separation after stratification is effected is by other than magnetic means, while in the other subclasses the magnet complete a separation.
SEE OR SEARCH THIS CLASS, SUBCLASS:
38, 39 and 40, for combinations of magnetic separation with sifting, fluid suspension separation or stratifying.
