DEFINITION

Classification: 516/140

The agent is liquid bath or liquid which acts to physically or chemically dissolve, bind, or destroy at least part of one liquid phase (except a colloid system making or stabilizing agent) (e.g., aqueous CaCl 2 for chemically binding water):

(under subclass 139) Subject matter in which the breaking

(resolving) or inhibiting agent* contains liquid bath or liquid which acts to physically or chemically dissolve, bind, or destroy at least part of one liquid phase (except a colloid system making or stabilizing agent*), such as, aqueous CaCl 2 for chemically binding water.

(1) Note. Agents* which bind includes material* that chemically hydrates (i.e., they bind water).

(2) Note. Subject matter of the class which encompasses agents* which act solely on a colloid system making or stabilizing agent* is excluded from this subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

135, for dilution performed only with a material* which is the same as the primary component of one of the two liquid phase in order to effect breaking (resolving) or inhibiting of a colloid system, and not combined with a step of vaporizing, heating, or cooling (as provided for subclasses 194+, below) and not combined with a step of centrifuging, mechanical shocking, or specified agitating (as provided for in subclass 197, below), there being no indented subclass providing for this subject matter.

136+, for subject matter in which the breaking (resolving) or inhibiting agent* contains a solid surface functioning material*, i.e., solid adsorbent, absorbent, or differential adherence surface, such as, filter media, sharp edged particles.

196, for subject matter related to breaking (resolving) or inhibiting of emulsions using vaporizing, heating, or cooling and further combined with diluting with a principal component of one of the phases, and without using an added material* dissimilar from the primary component of both liquid phases. 197, for subject matter related to breaking (resolving) or inhibiting of emulsions using centrifuging, mechanical shocking, or specified agitating, and without using an added material* dissimilar from the primary component of both liquid phases.
