(1) Explosive; explosive compositions for the purpose of this
class are those containing both a fuel and sufficient oxygen or
an oxidizer so that, upon initiation, they are capable of undergoing
a chemical change at a relatively high rate of speed, or a speed
approaching instantaneous, resulting in the production of usable
force through chemical change in the composition to produce gaseous
products and usually heat, and are used for blasting, firearms,
jet propulsion of rockets, vehicles, etc., rapidly filling automotive
passenger-restraining gas-bags, etc. See Glossary, below.
(2) "Thermite"; "Thermite-type" compositions
for the purpose of this class include; (a) a consumable fuel component
which is any of metal (alloy and intermetallic compounds), metal-metalloid
compounds, metalloids, and hydrides of metals or metalloids; (b)
and in combination therewith an oxidant component which is either
a metal oxide, inorganic oxygen salts and organic metal salts capable
of yielding a metal oxide on decomposition, which components, depending
upon the manner reacted, produce quantities of heat and chemical
by-products, either solid or fluid which by-products may be recoverable.
These compositions, by way of examples, are employed to produce
usable heat and light, chemical products and especially metals,
in pyrotechnics and incendiary, match compositions and smokes and
for explosive priming or as additives for explosive compositions.
Included within this definition are unreacted mixtures of metals
with metalloids because, though they contain no oxidant, they nevertheless
react similarly to "Thermites" to yield usable
heat. Also included are thermite compositions which contain an additive
designed to prolong heating effects, reduce the production of gas
or other by-products or otherwise moderate the exothermic activity of
the composition.
(3) Fuel specialized for jet-rocket engine and intended for
reaction with an oxidant therein, excluding air, in order to provide
thrust for motive power purposes.
(4) For use in neutralizing the poisonous gases of explosives.
(B) Methods of preparing or treating such compositions not
otherwise provided for. The classification of processes is based
upon particular components of the explosive or thermic composition.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Compositions are in this class when defined as charges or
forms which, in addition to the composition, set out nominal structure
or shape of the charge or component thereof, unless the structure
and/or size is such that there is imparted to the charge
or component the capacity to function, as an individual unit to
produce or alter a particular explosive or thermic effect, for which
structure or form see Class 102. However, plural components associated
as layered charges are in Class 149 if no particular structure and/or
size of any of the layers is set forth.
Jet and rocket engine fuels are classified in this class when
(a) the fuel component includes an oxidant component in sufficient
quantity to provide the major portion of oxygen necessary for its
combustion, or (b) when the fuels are specialized for jet and rocket
use only and are contemplated to be combined with an oxidant other than
air, except that included herein are those fuels which are known
to be, or are disclosed as being, hypergolic even with air as the
oxidant.
Conventional fuels, including those disclosed as being capable
of use in turbo, ram or pulse jet power plants and which include
such additives as anti-corrosion substances or ignition promotors,
are in Class 44.
Compositions claimed as fuels and disclosed as being capable
of functioning either with air or with other oxidants are classified
in Class 44; see below with respect to the "Search" references
involving Classes 44 and 75.
The rules for determining Class placement of the Original
Reference (OR) for claimed chemical compositions are set forth in
the Class Definition of Class 252 in the section LINES WITH OTHER

SECTION IV - GLOSSARY
CHARGE
As used herein refers to a mixture of ingredients producing
a composition of this class or a definite quantity of shapeless
or structureless material forming a composition of this class; or
at least two compounds or compositions or any mixtures of these
associated together or composited but in an unmixed condition, e.g.,
a primary explosive associated but not intermixed with a secondary
explosive, or those compositions including only nominal structure
or form.
EXPLOSIVE OR THERMIC COMPONENT
As used in this class covers (1) explosive or thermic compositions,
per se, (2) the oxidant portion, (3) the fuel portion of such compositions.
See also (4) Note class definition.
EXPLOSIVE COMPOSITIONS
Are classified (a) as HIGH EXPLOSIVE, which, for the purpose
of this class, is one whose rate of reaction is substantially instantaneous
or detonating in character, and is either (1) an extremely sensitive
or highly reactive or detonating chemical compound which is known as
a PRIMARY EXPLOSIVE and is used to initiate the secondary or other
explosive component of the charge; or (2) is a composition of a
combination of two or more primary explosives and as such is known
as a SECONDARY or other DERIVED EXPLOSIVE. Such an explosive reacts
with detonating force or brisance which is sufficient to shatter
the surrounding medium; (b) as LOW EXPLOSIVE, which for the purpose
of this class, is controlled to some time interval, less than instantaneous,
and as compared to that of high explosive, is slow or deflagrating
(burning) in character. It has the property or power to displace
the surrounding medium. Although it may be used for certain blasting
purposes it is used principally as PROPELLANT to set in motion bullets,
missiles or similar devices regardless of size.
FUEL COMPONENT:
For the purpose of this class is a material intended
for reacting, or to be used in combination, with an oxidant component
and includes such finely divided materials as metals (including
alloys and intermetallic compounds), metalloids, metal-metalloid
compounds, hydrides of metals or metalloids, carbon, sulfur, vegetable
material, carbohydrates, hydrocarbons and nitrogen containing organic
compounds generally. (Certain substances as gels, paraffins, sulfur,
etc., need not be finely divided.)
GRAIN OR POWDER
In the armament arts refers to a charge exhibiting certain definite
structural characteristics, but as used in this class the mere reference
to "grain" or "powder" without recitation
of definite structure, or with reference merely to nominal shape,
will be construed as being virtually synonymous with the term "granule" and
with finely divided "particulate" or "powdered" material.
MATRIX
As used in this class refers to a shapeless mass resulting by
solidifying at least one component from either its liquid or molten
state in more or less a continuous phase and wherein there is dispersed
throughout at least a second component in particulate form and in
substantially a discontinuous phase.
NITRATE V. NITRO
The term "nitrate" is generally used
as a suffix in the name of an organic compound, e.g., an ester containing the
-ONO2 radical, e.g., guanidine nitrate, while "nitro" is
generally used as a prefix to designate an organic compound having
the -NO2 radical, e.g. nitro-guanidine. The
art, however has not maintained this distinction in all cases and
thus compounds having the -ONO2 radical which
should be known, more properly, as "nitrates",
instead, have been known through the years as "nitro" compounds.
No attempt is made in this class to correct this situation and
the terms as applied to these compounds in this class are the same
as are currently accepted and used in this and related arts. For
example, the nitrates of such compounds as cellulose, glycerine and
starch, among others, are commonly known as "nitro-cellulose", "nitroglycerine" and "nitro-starch" respectively,
and when they so appear in this class, the reference, in spite of
the inconsistency, is to a compound of the -NO3 radical
or -ONO2.
NITRATED
As used in this class, unless otherwise specified, is intended
as a generic expression for compounds or substances both organic
and inorganic which contain at least one of the empirical radical
(s)-(ONOx)y or -(NOx)y,
wherein "x" and "y" are whole
numbers. Predominately, in this class "x" is
2 and "y", where the compound permits, is 3 or
more.
OXIDANT COMPONENT:
As used in this class relates to that portion of a composition
which carries sufficient available oxygen to oxidize at least a
substantial portion, if not all, of the fuel component of the composition,
and includes metal oxides, and organic compounds capable of yielding
metal oxide, nitrogen-oxygen or oxygen-halogen salts which are either
organic or inorganic, including the oxides and acids of nitrogen-oxygen,
liquefied gaseous material, and in the case of "Thermites" only,
any inorganic oxygen salt.
THERMIC COMPONENT:
(See explosive component) is similar to an explosive component
as defined above except that the component may not react quite with
the speed or power of an explosive and includes such compositions
or components thereof as "Thermite", pyrotechnic,
incendiary, fuse, match, smoke, or those compositions or components thereof
which react or are capable of reacting to yield usable quantities
of heat with or without desired chemical products.
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".
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.
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.
Fuel and Related Compositions,
subclasses 506+ for a solid fuel combined with a composition of
this class, subclasses 520+ and 530+ for a solid
fuel product having a defined shape or structure and subclasses
542+ for a solid fuel composition coated or impregnated
for easier ignition.

charge or composition within a container the latter defined either
structurally or by dimension; and
subclasses 283+ for charges (grains) defined by particular shape
or structure or dimension, e.g., grains or charge of a specified
size or grains having specified web or perforations. See also "(2)
Note", of this subclass.

or natural rubber having utility as a binder in a solid propellant
composition or to processes of preparing said composition.
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.
Ammunition and Explosives, appropriate subclasses, and particularly
subclasses 283+ for coated preshaped explosive charges, grains
or units, and see "(3) Note" to this subclass,
(of Class 149).

530-570, and Class 585, Chemistry of Hydrocarbon Compounds, appropriate subclasses for organic compounds, including
explosive compounds, when treated with a preservative unless the "preservative" is
disclosed as further aiding the explosive or thermic properties
of the compound.
This subclass is indented under subclass 3. Compositions or products in which the base (or support)
contains both organic and inorganic explosive or thermic materials.
(1)
Note. For definition of "explosive or thermic materials",
see the class definition Glossary
This subclass is indented under subclass 3. Compositions or products in which the base (or support)
is an inorganic explosive or inorganic thermic compound or element.
(1)
Note. See "(1) Note" under the definition
of subclass 4.
This subclass is indented under subclass 6. Compositions or products in which the base (or support)
is an inorganic explosive or inorganic thermic salt.
This subclass is indented under subclass 9. Compositions of products in which the base or support is

Note. See "(1) Note" under the definition
of subclass 47.
This subclass is indented under subclass 2. Products which include at least two separate and distinct
superimposed or contiguous layers or forms of different components
or of components having different properties; e.g., one layer may
constitute the base charge and a second layer the primer charge.
(1)
Note. The layers or forms may be in loose particulate form
or in a solid or compacted form.
(2)
Note. The layers or forms must be in direct contact and must
not be separated by space or other nonexplosive or nonthermic body.
Ammunition and Explosives, appropriate subclasses and particularly
subclasses 200+ , 320, 338, 352, 360, and 443, among others, for
ammunition devices utilizing the subject matter of this and indented
subclasses.

This subclass is indented under subclass 14. Composite charges wherein at least one of the layers of
the composite contains an inorganic explosive or inorganic thermic
material.
(1)
Note. See "(1) Note" under the definition
of subclass 4.
This subclass is indented under subclass 15. Composite charges wherein at least one of the layers of
the composite contains an inorganic azide and/or fulminate
and/or phosphorus or binary compound of phosphorus (excluding oxides
of phosphorus).
This subclass is indented under subclass 2. Product containing particulate material dispersed substantially
entirely within a solidified or matrix medium and which products
are characterized by dispersed phase within a continuous phase.
(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.
