DEFINITION

Classification: 149/2

(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 structure and subclasses 542+ for a solid fuel composition 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 perforations. See also "(2) Note", of this subclass.

502, Catalyst, Solid Sorbent, or Support Therefor: Product or Process of Making,

527.11, 527.24 for an art collection of sorbents or catalysts having particular shape or structure.

520, Synthetic Resins or Natural Rubbers, appropriate subclasses, particularly Class 523,

180, for a composition containing a synthetic resin or natural rubber having utility as a binder in a solid propellant composition or to processes of preparing said composition.
