DEFINITION

Classification: 44/563

With fibrous vegetable material, resin, or organic -C(=O)O- compound (e.g., rosin, tall oil, tallow, pine resin, etc.):

(under subclass 559) Subject matter wherein the consolidated solid fuel composition also contains fibrous vegetable material, resin, or an organic -C(=O)O- compound.

(1) Note. Fibrous vegetable material is vegetable material whose fibrous nature has not been destroy by processing;

examples of fibrous vegetable materials are paper, cellulose, wood, bark, and sawdust.

(2) Note. The term "resin" is intended to include all material identified as unspecified resin, all natural resins, and synthetic resins not prepared by polymerization or copolymerization of a specified monomer or specified monomers.

(3) Note. An organic -C(=O)O- compound is one in which the carbon of the -C(=O)O- group is, or is attached directly or indirectly by nonionic bonding to, the carbon of an organic compound.

(4) Note. See Glossary in the class definition of the definition of "organic compound".

(5) Note. The components of the consolidated solid fuel compositions specified in this subclass normally, but not necessarily, serve a binding function.
