DEFINITION

Classification: 209/183

(under subclass 174) Apparatus and methods for delivering material to be separated below the surface of the body of liquid material which serves to float the lighter components and to retain the heavier.

(1) Note. This subclass and the subclasses indented under it do not include such cases as do not involve the initial subsurface delivery of the material, cases where the material is submerged only after a preliminary surface delivery which permits the heavier to sink in the metallic bath not being ordinarily included.
