DEFINITION

Classification: 516/33

The material primarily contains inorganic material (e.g., chrome yellow, sodium nitrite):

(under subclass 31) Subject matter in which the discontinuous phase material* is primarily inorganic* material*, such as chrome yellow, or sodium nitrite.

(1) Note. "Primarily contains inorganic* material*" means that 50% or more is inorganic* material*, by weight, volume, molecule, or atom.

78+, for colloid systems (e.g., suspensions, or dispersions) in which the continuous liquid phase is aqueous and the discontinuous phase is primarily solid which is primarily inorganic* material*.

51, Abrasive Tool Making Process, Material, or Composition, appropriate subclasses for materials, compositions, colloid systems, wetting agents, subcombination compositions therefor, or appropriate methods designed for an abrading purpose.

113, for image developing composition or product which is a multiple phase liquid carrier medium, such as an emulsion, for electric or magnetic imagery, subclasses 377+ for emulsifier in a coupling compound with silver compound sensitizer in a process of color imaging using a radiation sensitive composition, and subclass 493 for surfactant or emulsifier processing additive in a developer for nonradiation sensitive image processing compositions or process of making. 505, Superconductor Technology: Apparatus, Material, Process,

90, for compositions for addition to petroleum oils during transportation through conduits to prevent fouling or clogging of the conduits due to components of the petroleum oils precipitating out during the transportation (e.g., suspending agents, antiflocculants), subclasses 100+ for earth boring compositions which may contain colloid systems (e.g., dispersions, suspensions, emulsions) or wetting agents, and subclasses 200+ for well treating compositions which may contain colloid systems (e.g., dispersions, suspensions, emulsions) or wetting agents.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions, appropriate subclasses for claimed or solely disclosed cleaning compositions for cleaning or removing foreign matter from solid surfaces which may be dispersions or suspensions of solid or semi-solid material in organic liquid phase. Although various subclasses specifically provide for colloid systems or wetting agents, such subject matter may be placed based upon another criterion, such as its chemical constitution (i.e., as though it has no colloid system characteristic). Areas known to have documents related to dispersion or suspension colloid systems (e.g., slurry) include:

133+, for composition for cleaning human skin (especially subclass 139 for particulate containing which may be colloid-sized), subclasses 276+ for cleaning compositions for textile material (e.g., laundry detergent) (particularly subclasses 337+ for liquid compositions (e.g., slurry) which may be colloid systems), subclasses 367+ for cleaning compositions with oxygen or halogen containing chemical bleach or oxidant component (particularly subclasses 368+ for with scrubbing or scouring component (e.g., abrasive, slurry), subclass 370 for liquid, paste, foam, or gel (e.g., slurry, aerosol composition or package)), subclasses 395+ for cleaning composition with a scrubbing or scouring component (e.g., containing an abrasive, cream, paste, gel, gas-propelled, slurry), subclass 404 for cream or paste cleaning composition, subclasses 405+ for liquid cleaning compositions, especially for chemically specified surfactants (particularly subclass 418 for liquid and solid phases (e.g., suspension, slurry)), and subclasses 535 for surfactant compositions (other that raw soap) which are specialized for use in cleaning compositions together with other auxiliary components (particularly subclass 537 for liquid or paste).
