DEFINITION

Classification: 209/155

(under subclass 132) Methods and means wherein liquid is employed as the assorting medium.

(1) Note. While some of the subclasses indented hereunder are analogous to the subclasses indented under Fluid, Gaseous, above, other properties of liquid are availed of, such as specific gravity and surface tension. In the subclasses analogous to those involving gaseous fluid water is generally the medium, while where surface tension is involved water or aqueous solutions may be employed, and in those cases involving specific gravity water, aqueous solutions or suspensions, and liquid or liquefied metal may be employed.
