DEFINITION

Classification: 149/37

(under the class definition) Compositions which contain at least one metal or metalloid and at least one oxygen supplying material which may be a metal oxide, an inorganic metal or ammonium salt, or an oxygen-containing organic salt and the resulting mixture must be capable of reacting to yield heat and reaction by-products.

(1) Note. This and indented subclasses include patents to compositions which have become known as "Thermite" or "Thermite type" or compositions containing "Thermite" or similar mixtures as constituent material. See Class definition for description and also see the Glossary.

(2) Note. Included under the term "metalloid" are the elements: selenium, silicon and tellurium.

44, Fuel and Related Compositions,

3.6+, for water-activated compositions which may be otherwise similar to those contained herein. 75, Specialized Metallurgical Processes, Compositions for Use Therein, Consolidated Metal Powder Compositions, and Loose Metal Particulate Mixtures, appropriate subclasses, particularly

27, for processes of producing metals utilizing compositions of this and indented subclasses, subclasses 228+ for a composition having a continuous phase of free metal made by consolidating metal particles, and subclasses 252+ for a loose metal particle composition, mixed with particles of nonmetal.

104, Railways,

15, for track welders using compositions of this and indented subclasses.

126, Stoves and Furnaces,

263.01+, for heaters or stoves utilizing the compositions of this class as the means for producing heat. Patents including the composition in combination are also classified in this subclass (of Class 126).

164, Metal Founding,

53+, for metal casting utilizing a reactive heating composition.

228, Metal Fusion Bonding,

101+, especially subclasses 234.3+ for soldering, welding or

brazing wherein bonding heat results from the reaction of a composition of this or the indented subclasses.

428, Stock Material or Miscellaneous Articles, 546+, for stock material manufactured from particulate metal or a mixture of metal and nonmetal particles.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting,

1+, for continuous gas or vapor phase colloid system (e.g., smoke, fog, aerosol, cloud, mist) or agents for such systems or making or stabilizing such systems or agents, when produced by reactions other than by combustion or "Thermite-type", subclasses 98+ for colloid systems of continuous or semicontinuous solid phase with discontinuous liquid phase (gels, pastes, flocs, coagulates) or agents for such systems or making or stabilizing such systems or agents; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.
