DEFINITION

Classification: 516/115

Continuous liquid phase colloid system and discontinuous gas or vapor phase (i.e., foam):

(under subclass 113) Subject matter in which the colloid system subject to breaking (resolving) or inhibiting is a continuous liquid phase with a discontinuous gas or vapor phase (i.e., foam).

SEE OR SEARCH THIS CLASS, SUBCLASS:

113, for similar subject matter related to breaking (resolving) or inhibiting of colloid systems other than smokes or fogs (as provided for in subclass 114) or emulsions (as provided for in subclasses 135+), such as, with a continuous liquid phase and a discontinuous solid phase (solid particle sols) or with a continuous solid phase (gels).

114, for similar subject matter related to breaking (resolving) or inhibiting of colloid systems with a continuous gas or vapor phase (fogs, smokes).

135+, for similar subject matter related to breaking (resolving) or inhibiting of colloid systems with a continuous liquid phase and a discontinuous liquid phase (emulsions).

904, for a collection of art which discloses foam breaking or inhibiting subject matter in the context of fermentation technology.

73, Measuring and Testing, 19.01+, for a process or an apparatus for determining the nature or amount of gas in a substance other than gas.

95, Gas Separation: Processes,

57+, for processes using electric or electrostatic field (e.g., electrostatic precipitation, etc.), subclass 150 for contacting fluid mixture with a liquid and including foaming of liquid to aid in the separation, subclass 155 for contacting fluid mixture with a liquid and including defoaming or antifoaming agent, subclass 157 for contacting fluid mixture with a liquid to degasify and including defoaming, subclasses 241+ for processes of degasification of a liquid (subclass 242 for defoaming and subclass 253 for emulsion breaking or multiple liquid separating).

137, Fluid Handling,

170.1+, for apparatus for foam control in gas charged liquids.

184, Lubrication,

6.23, for devices which include means to destroy or remove gas or vapor bubbles dispersed in the lubricant.

201, Distillation: Processes, Thermolytic,

9, for process including a step of surface treating solid carbonaceous material to reduce or prevent agglomerating or foaming or swelling during distillation.

20, for processes under that Class definition including defoaming or inhibiting foam.

209, Classifying, Separating, and Assorting Solids,

163+, for methods and means wherein some material is caused to adhere selectively (i.e., to some constituents and not to others) which so lightens the material constituents to which it is attached as to cause them to float on the liquid, while the other constituents are not floated (e.g. bubbles are caused to attach to some components of a material or mixture of solid materials and not to others, the components to which the bubbles are attached being caused thereby to float on the surface of the liquid).

426, Food or Edible Material: Processes, Compositions, and Products,

329, wherein a food foam is protected against deterioration, or wherein a food is protected against undesirable foam formation by contact with a change inhibiting chemical agent other than an antioxygen agent.

435, Chemistry: Molecular Biology and Microbiology,

262+, for processes in which preexisting material or compound, which may include a hazardous or toxic waste, present in a composition or material containing a preexisting material, is contacted with an enzyme or immobilized enzyme micro-organism or plant or animal cells to isolate or recover the preexisting material which is chemically unchanged by the process and the hazardous or toxic waste is destroyed (especially subclass 262.5 for processes wherein hazardous or toxic waste such as oil spill is destroyed or converted into an environmentally safe substance, subclass 266 for processes of using enzyme or microorganism to liberate, separate, or purify by treating gas, emulsion, or foam, subclasses 281+

for processes of recovering petroleum or shale oil), foreign art collection FOR 184 for method of using gentically engineered cells other than hybrid or fused cells for oil spill cleanup.
