DEFINITION

Classification: 524/62

With hydrocarbon DNRM additive which is nonresinous and which is nonbituminous, or noncoal derived, e.g., cutback asphalt, kerosene, paraffin wax, etc.:

(under subclass 59) Subject matter wherein the DNRM is admixed with a DNRM which is a hydrocarbon material and which is other than coal or a bituminous material or a hydrocarbon material proper for this subclass as a designated nonreactant material.

(1) Note. Included within this subclass as hydrocarbon materials are hydrocarbon waxes, fluxing oils, low molecular weight hydrocarbon addition polymers, hydrocarbon petroleum distillation products, petroleum, petroleum crude oils, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

59, for substances derived from coal or bituminous material. Certain special hydocarbon compounds specifically excluded from subclass 59 (see notes 2 and 5 therein) will qualify for this subclass when in admixture with a designated nonreactant material proper under the definition of subclass 59.
