DEFINITION
Classification: 62/543

(1) Note. The pressure applied is such as to remove occluded liquid or cause some minor surface melting to remove surface impurities from the solidified constituent.
(2) Note. A process including centrifugation is excluded from this subclass unless the force exerted on the solid in the centrifuge is claimed as either a specific force exerted on the solid or specific RPM of the centrifuge.
