DEFINITION

Classification: 106/163.01

Cellulosic material:

(under subclass 162.1) Compositions wherein the carbohydrate is cellulose with the following structure, below, or the reaction products wherein the carbon skeleton of the cellulose is not destroyed or a naturally occurring material which has cellulose as one of its ingredients. [figure]

(1) Note. This subclass and indented subclasses provide for lignocellulosic material (e.g., wood, bark, etc.), relatively pure cellulose (e.g., cotton linters, etc.), regenerated cellulose (e.g., cellophane and rayon), or chemically modified forms of cellulose (e.g., pyroxylin, viscose, etc.) for which there is no provision elsewhere.

(2) Note. The expression "organic compound" in this and indented subclasses corresponds to the Class 260 class definition; i.e., compounds containing carbon, which are further characterized by the presence in a molecule thereof of (a) two carbon atoms bonded together, (b) one atom of carbon bonded to at least one atom of hydrogen or halogen, or (c) one atom of carbon bonded to at least one atom of nitrogen by a single or double bond, with the proviso that HCN, CN-CN, HNCO, HNCS, cyanamide, cyanogen halides, fulminic acid, metal carbides, and graphite are excluded from being organic compounds.

(3) Note. The term "carbohydrate or derivative" in this and indented subclasses corresponds to Class 536 subclass 1.1 definition; i.e., saccharide whose monomeric units are polyhydroxy mono-aldehydes or polyhydroxy mono-ketones, having the formula Cn(H2O)n[end

subscrpt] (wherein n is five or six), or the corresponding cyclic hemiacetals thereof; or the reaction derivatives thereof in which the carbon skeleton and the carbonyl function or hemi-acetal function of the saccharide unit are not destroyed.

(4) Note. The term "alloy" in this and indented subclasses corresponds to Class 75 class definition; i.e., a union, possessing metallic properties of two or more metallic elements or of nonmetallic element(s) and metallic elements(s) which are not pure compounds and which are miscible with each other, which at least to a certain extent when molten forms a more or less homogeneous liquid having a metallic matrix and which does not separate into distinct layers when solid. Such combinations when solidified from a melt may consist of mechanical mixtures, entectics, entectoids, solid solutions, or in part of chemical compounds one or more of which may exist at the same time. Intermetallic compounds are considered alloys for purposes of classification.

(5) Note. The term "hetero ring" in this and indented subclasses corresponds to Class 532 class definition; i.e., a ring having only carbon and at least one atom from the group consisting of nitrogen, oxygen, sulfur, selenium and tellurium as ring members.
