DEFINITION

Classification: 516/2

Discontinuous phase formed by combustion or oxidation/reduction reaction (e.g., smudge-pot smoke):

(under subclass 1) Subject matter in which the discontinuous phase contains material formed by a combustion reaction or an oxidation/reduction reaction.

SEE OR SEARCH THIS CLASS, SUBCLASS:

4, for discontinuous phase formed by a hydrolysis step, such as metal oxide from metal chloride/water reaction.

10+, for colloid systems of continuous liquid phase and a discontinuous gas or vapor phase (i.e., foam), and propellant per se, therefor.

43, Fishing, Trapping, and Vermin Destroying,

124+, for process and apparatus the primary object of which is to destroy or kill vermin without trapping them (particularly see subclasses 125+ for apparatus for creating or involving fumes or smoke when such fumes are used for destroying vermin and not for general disinfecting or similar purposes, subclass 132.1 for devices or processes under subclass 124 for destroying invertebrate animals, i.e., insects), cross-reference art collection 900 for apparatus for dispersing i.e., spraying, a liquid mass or jet of droplets used to destroy insects. 102, Ammunition and Explosives,

334, for apparatus for and methods of smoke generating (i.e., causing vapor, cloud, etc., to be formed by a burning), subclasses 335+ for pyrotechnics apparatus and corresponding methods designed to produce smoke, light, heat, and/or noise (e.g., fireworks display, amusement, flash photo, signal), subclasses 367+ for apparatus for or methods of using an explosion to cause a liquid, solid, or gas to be scattered or spread about in the form of a mist, vapor, particles, or gas (e.g., noxious or incapacitating, plant, insect, animal, foliage, biological warfare/chemical warfare).

126, Stoves and Furnaces,

59.5, for portable devices for generating heat or smoke for protecting orchards from frost (e.g., smudge pots).

149, Explosive and Thermic Compositions or Charges, appropriate subclasses for explosive and thermic compositions and methods of preparing or treating such compositions, where the latter are used to produce usable heat or flame or by-products resulting from the use of such compositions (e.g. smoke flares). See various subclasses based on active composition for explosive or thermic compositions which may be gels or pastes or may be intended to yield smoke as result of combustion (particularly

29+, 37+, and 78+), subclasses 17+ for compositions containing particulate material dispersed substantially entirely within a solidified or matrix medium and which are characterized by dispersed phase within a continuous phase, subclass 108.4 for smoke affecting composition (e.g., coloring), subclass 108.8 for compositions containing a stability or viscosity agent (e.g., gelling, thickening, thinning, liquefying, etc., agent, a stabilizer or unstabilizer (activator), a burning rate modifier), cross-reference art collection 110+ for compositions or

processes reciting or disclosing a reference to a particular size or dimension of the particles of at least one of the ingredients or the size or dimension of all or part of the composition in particulate form, cross-reference art collection 117 for smoke generating or weather modifying composition with a resin, and cross-reference art collection 118 for composition containing a resin dissolved in the continuous phase of a gel.

424, Drug, Bio-Affecting and Body Treating Compositions,

40+, for combustible or chemically reactive compositions to produce a smoke, mist, or aerosol.
