DEFINITION

Classification: 516/910

The compound contains nitrogen, except if present solely as NH 4+:

A collection of art under cross-reference art collection 909 in which the colloid system making or stabilizing agent* which contains organic* compound containing sulfoxy* also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1+, for colloid system having a continuous gas or vapor phase (such as, smoke, fog, aerosol, cloud, mist) or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains Nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

14, for colloid system of continuous liquid phase and a discontinuous gas or vapor phase (i.e., foam) or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

26, for colloid system of primarily organic* continuous liquid phase and a discontinuous phase primarily inorganic* liquid (e.g., water-in-oil emulsion) or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

31+, for colloid system of primarily organic* continuous liquid phase and a discontinuous phase primarily solid or semisolid material* or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

41+, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily bituminous or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+. 59+, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily organic* liquid (e.g., oil-in-water emulsion) or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

77+, for colloid system of aqueous continuous liquid phase and a discontinuous phase primarily (non-bituminous) solid (e.g., water based suspensions, dispersions, sols) or method of making or stabilizing which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.

98+, for subject matter relating to colloid system having a continuous or semicontinuous solid phase (i.e., systems which

exhibit plasticity, elasticity, or rigidity), such as gel, paste, gelled emulsion, floc.

113+, for subject matter relating to breaking (resolving) or inhibiting a colloid system which employs as an agent* an organic* compound which contains sulfoxy* and also contains nitrogen, except for when the nitrogen is present solely as the cationic ammonium group, NH 4+.
