CLASS 149, EXPLOSIVE AND THERMIC COMPOSITIONS OR CHARGES

1	CONTAINING LIQUEFIED GASEOUS FUEL OR LIQUEFIED OXYGEN SUPPLYING MATERIAL:

This subclass is indented under the class definition. Compositions or charges in which the oxidant and/or fuel component are in a liquefied state.

(1) Note. These are materials that are normally gaseous, e.g., oxygen, air, ozone or certain hydrocarbons.

(2) Note. The liquefied material may be contained as an impregnant of an absorbent substance usually carbonaceous in nature, e.g., carbon, sawdust or other vegetable matter.

(3) Note. For definition of "fuel" and "oxidant", see the class definition Glossary and see Glossary also for definition of "charge".

SEE OR SEARCH CLASS:

502,	Catalyst, Solid Sorbent, or Support Therefor: Product or Process of Making, for a catalyst on a carrier which may include carbon and subclasses 400+ and 526 for a sorbent, per se, for liquified fuel or oxygen.

2	STRUCTURE OR ARRANGEMENT OF COMPONENT OR PRODUCT:

This subclass is indented under the class definition. Compositions or products which define (1) the particular shape or structure of at least one ingredient of the composition or product or the nominal shape and/or physical characteristic of the composition or product or nominal shape of the container therefor; (2) a solid-solid suspension, (a solid dispersed within a solidified matrix material); (3) a compacted or bonded mass of ingredients; (4) products wherein at least one ingredient of the composition or charge is coated; and (5) at least two separate contacting layers or bodies and in which each layer or body is composed of a different ingredient or ingredients each having different properties or different compositions. See Lines With Other Classes and Within This Class in the class definition.

(1) Note. Designation of an ingredient or composition as granular or particulate is not considered as defining a particular shape or structure for this and indented subclasses. See Glossary under the class definition.

(2) Note. A particular shape for this and indented subclasses is, for example, globular, needle, spherical, rectangular, sheet, cast body, pellet, etc. A physical characteristic is stating the particle size of an ingredient or the density of a composite. Defining the composite by differences in its internal and external density or defining the composite as "puffed" is considered "nominal" structure for this and indented subclasses. See Glossary under the class definition.

3	. Coated component:

This subclass is indented under subclass 2. Compositions or products in which at least two of the components are associated together such that one constitutes a coating and the other a base or support for the coating.

(1) Note. This and indented subclasses take patents relating to coated explosive or thermic compositions or products and to components thereof under the definition of this class and to coating processes when intended to aid or otherwise beneficially modify the explosive or thermic properties of the material. The coating, per se, of nonexplosive or nonthermic material or of explosive compounds for such purposes as preservation, or to render the material insensitive, is in the appropriate material class or coating class.

(2) Note. The term "coating" as used in this and indented subclasses has the same scope as that found in the class definition of Class 427, Coating Processes, except that "impregnation" is not considered to be "coating" for these subclasses unless the patent makes it clear that the characteristics of only the surface of the material is modified. Generally, patents are not considered for this and indented subclasses which involve merely the addition of a liquid portion to an adsorbent portion or to a composition or product that contains or serves as an adsorbent.

(3) Note. Patents for products or charges which are defined by composition and structure, even though the structure is only nominally recited are classified in Class 102, Ammunition and Explosives, when the overall charge or unit is claimed as being coated.

(1) Note. See part "(2)" of the definition of subclass 2 and see also "(1)" Note", f. of the class definition.

(2) Note. The product for this and indented subclasses is usually obtained by (a) forming a dispersion of particles (and maintaining them as such) in a liquid followed by solidifying the liquid to yield a homogeneous two phase mass or by melting at least one phase of a solid multiphase system followed by solidifying, e.g., freezing, setting, curing, solvent removal, etc., or (b) similarly forming a homogeneous two phase mass by mixing at least two liquids having different solidification temperatures, the first to solidify being formed into granules and dispersed in the last liquid to solidify the latter serving as the matrix and (c) milling or kneading a plastic, stiff paste or dough material containing a particulate material to form a two phase homogeneous mass. Excluded however, are those products or compositions wherein the "particulate material" is a filler, color, dye or similarly nonexplosive material. For the purpose of this and indented subclasses the presence of at least 10% of the matrix-phase material is arbitrariconsidered to be a sufficient quantity to inherently form the matrix in continuous phase unless the patent specifically teaches to the contrary.

(3) Note. Patents are not classified within this and indented subclasses which involve merely the addition of a liquid to particulate material where the latter serves as a carrier or adsorbent for the liquid (even though the liquid is said to be a binder) where such liquid is, for example, either fugitive, remains as liquid or evaporates leaving a solid particulate residue.
