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

form, or forming a portion of the unitary structure.

here as synonymous with finely divided particulate or powdered material,

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,

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.
