DEFINITION

Classification: 516/197

Breaking (resolving) or inhibiting by centrifuging, mechanical shocking, or specified agitating:

(under subclass 135) Subject matter in which breaking (resolving) or inhibiting the emulsion colloid system is performed by centrifuging, mechanical shocking, or specified agitating.

(1) Note. Specified agitating means the operation or step of agitating includes more than merely the use of the term agitating or synonym thereof, such as, a stated RPM, high-shear, specified impeller type, length of time. If the specific feature is not claimed, placement is not mandatory.

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.

139+, for similar subject matter related to breaking (resolving) or inhibiting of emulsions using an agent* which contains material* different from the primary components of both liquid phases of the colloid system, other than as provided for in subclasses 136+ (using an agent* which is solid surface functioning), and other than as provided for in subclass 140 (physically or chemically dissolving binding, or destroying or at least part of one liquid phase (other than the colloid system making or stabilizing agent*)); particularly subclass 141 for breaking (resolving) or inhibiting of aqueous-petroleum*, petroleum*-aqueous, aqueous-hydrocarbon, or hydrocarbon-aqueous emulsions using an agent* which contains a material* which is only inorganic*, and subclass 142 for breaking (resolving) or inhibiting of aqueous-petroleum*, petroleum*-aqueous, aqueous-hydrocarbon, or hydrocarbon-aqueous emulsions using an agent* which contains a material* which contains both organic* material* and inorganic* material*.

194+, for subject matter related to breaking (resolving) or inhibiting of emulsions using vaporizing, heating, or cooling, and without using an added material* dissimilar from the primary component of both liquid phases.
