.~.~.~> Foam-stabilizant or colloid-stabilizant containing
DEFINITION
Classification: 252/6
(under subclass 4) Compositions which contain components for generating gas by chemical interreaction of such components, substances peculiar thereto, or processes which include such interaction.
(1) Note. Claims which are drawn to compositions which are chemically decomposable by heat to form a fire extinguishive gas, but do not contain individually components which are
adapted to chemically interreact to produce a gas are not classified in this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS:
3, for fire extinguishive foams.
61, for compositions for making foam for froth flotation.
SEE OR SEARCH CLASS 516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting,
10+, for foam colloid systems or agents for such systems or making or stabilizing such systems or agents, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.
