DEFINITION

Classification: 516/114

Continuous gas or vapor phase colloid system (e.g., fog dispelling, dust or contrail suppressing):

(under subclass 113) Subject matter in which the colloid system subject to breaking (resolving) or inhibiting is a continuous gas or vapor phase, such as, fog dispelling, dust suppressing, contrail suppressing.

SEE OR SEARCH THIS CLASS, SUBCLASS:

113, for similar subject matter related to breaking (resolving) or inhibiting of colloid systems other than foams (as provided for in subclass 115+) 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).

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

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).

454, Ventilation, cross-reference art collection 901, for fog dispeller, i.e., comprising means for eliminating or dispersing cloud-like, condensed water vapor which is positioned close to a ground surface.

216, for compositions facilitating sweeping uncarpeted floors by reducing the amount of dust that becomes airborne. 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).
