SECTION I - CLASS DEFINITION
This is the residual class for ammunition propelled by explosives
and explosives methods or means which includes:
Missile, blasting means, payload, pyrotechnic, gun ammunition
and/or miscellaneous explosive means.
Gun barrel cleaning means which are propelled through the
barrel by explosive or fluid under high pressure.
Fluid under high pressure, other then chemical reaction, which
escape very rapidly.
Material which burns or combusts which is intended to be projected,
dropped, thrown, or propelled is proper for the class. (1) By releasing
a combustion material to the atmosphere, e.g., gas, incendiary shell,
grenade, etc. (2) By generating heat to damage an object, e.g.,
thermite means.
Subcombinations peculiar to the class which are not classified
in other classes, e.g., cartridge case, primer ignitor, fuse, sabot,
rifling band, wad, propellant form, etc.
Dummy, practice, drill, training ammunition, etc., is classified
with the conventional ammunition.
Patents issued prior to 1950 have not in all instance been classified
by their claimed disclosure but by their total disclosure so that
placement of these older patents does not necessarily indicate lines
of classification.
The Search Notes below also contain classification lines.

| | This subclass is indented under the class definition. Subject matter which includes method and apparatus including
a chemically reactive combustible composition having more than a nominal
solid propellent form for the purpose of changing the burning rate

| | (1)
Note. The "solid propellent form" is defined
here as being a unitary mass of solid propellent composition or
a plurality of individual propellent forms united to define a unitary
or composite form which includes: (a) an external or internal surface
of specific configuration; (b) a burning rate modifier structure
which directs a flame front through the form (the "flame
front" is intended to be the actual burning surface of
the solid propellent form at any particular instant in the total
burning period); or (c) reinforcing or form support means attached
to or imbedded within or in immediate contact with the propellent
form, or forming a portion of the unitary structure.
| |
The solid propellent composition includes all detonating and
deflagrating compositions, including immediately adjacent oxidizer
and fuel compositions (see "(1) Note", Class 60,
Power Plants, subclass 205), which react under combustion to detonate
or deflagrate. It further includes a solid fuel or solid oxidizer
composition which is adapted to be brought in immediate contact
with a solid or fluid oxidizer or fuel, respectively, when combustion
is desired. For example, the solid propellent form used in reaction
motors of the type classified in Class 60, Power Plants, subclass
251 would be included under this definition. The solid propellent
composition referred to above excludes manufactured fuel of general
utility, such as fuel briquets which are provided for elsewhere, see
the search notes below. | |
| | (2)
Note. A "granule" of propellent is defined
here as synonymous with finely divided particulate or powdered material,
and further includes an individual propellent form which is disclosed
as used in combination with other unconnected granules of an identical
or similar shape, size, or composition which produce a combined
gas producing result upon combustion. Each granule burns individually
with its own individual characteristics depending upon its shape, size,
and composition. The individual characteristics of each granule
are combined with the characteristics of other unconnected granules
to produce a total desired result upon combustion. |
| | (3)
Note. A "solid propellent form" claimed with
only a nominal shape is provided for elsewhere, see the search notes below.
However if the "solid propellent form" is characterized
by structure or size such that there is imparted to the form the
capacity to function as an individual unit to produce or alter a
particular detonation or deflagrating effect the form is not regarded
as nominal and is classified under this definition.
| |
The following examples have been considered to be significant
inclusion of structure and if included would cause classification
in this class (102): (a) a generally perforated propellent mass combined
with a specific density; (b) a broadly configured mass (i.e., a
sheet) with at least one specific dimension; and (c) a porous propellent
mass claimed in combination with a capillary perforation extending
therethrough. | |
