Class 149
EXPLOSIVE AND THERMIC COMPOSITIONS OR CHARGES
Class Definition:
This class includes:
(A) Compositions which are:
(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.
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 CLASSES AND WITHIN THIS CLASS, subsection
COMPOSITION CLASS SUPERIORITY, which includes a hierarchical
ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.

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
-ONO[subscrpt]2[end subscrpt] radical, e.g., guanidine
nitrate, while "nitro" is generally used as a prefix to
designate an organic compound having the -NO[subscrpt]2[end
subscrpt] radical, e.g. nitro-guanidine. The art, however
has not maintained this distinction in all cases and thus
compounds having the -ONO[subscrpt]2[end subscrpt] 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 -NO[subscrpt]3[end subscrpt] radical or
-ONO[subscrpt]2[end subscrpt].
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)-(ONO[subscrpt]x[end subscrpt])y or
-(NO[subscrpt]x[end subscrpt])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.
SUBCLASSES
Subclass:
1
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 400 and 526 for a sorbent, per se, for
liquified fuel or oxygen.
Subclass:
2
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.

44, Fuel and Related Compositions, 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

coated or impregnated for easier ignition.
102, Ammunition and Explosives, appropriate subclasses, for
the combination of an explosive charge or composition within
a container the latter defined either structurally or by
dimension; and 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

or to processes of preparing said composition.
Subclass:
3
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.

of phosphorus).
Subclass:
17
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.
