SECTION I - CLASS DEFINITION
This class includes most patents for:
A liquid or solid composition designed primarily to react chemically, usually with oxygen in air, to produce heat in controllable amounts, included are most compositions designed to produce both heat and a deoxygenating effect in metallurgical and similar processes, designated to be dispersed in air for explosive combustion in an engine and/or designed to produce illumination light along with heat upon combustion.
A process for making such composition by adding substances, by removing components (using chemical or physico-chemical procedures) by shaping or reshaping or arranging fuel elements or object in a particular relation to each other, except where provided for in another class.
Apparatus specialized for use in an above process and not provided for in a single other class.
An additive which imparts desire aesthetic, handling or burning properties to a fuel, or a composition useful only for scratching a match or removing soot from a combustion-related apparatus.
Certain combinations of fuel with an igniting composition, an incombustible carrier for the fuel, a wrapper of bundling material or an additive as described above.
A solid product of a Class 201 thermolytic distillation process not elsewhere classifiable.
A process for treating coal not elsewhere classifiable.
SECTION II - NOTES TO THE CLASS DEFINITION
(1) Note. In this class a process for making a fuel product is classified with the product, except where specifically provided for elsewhere. |
SECTION III - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
When the expression "organic compound" is used in this class, it means a compound which fulfills the requirements of the Class 260 class definition, i.e., the molecule is characterized by two carbons bonded together, one atom of carbon bonded to at least one atom of hydrogen or halogen, or one atom of carbon bonded to at least one atom of nitrogen by a single or double bond. Certain compounds are exceptions to this rule, i.e., HCN, CN-CN, HNCO, HNCS, cyanogen halides, cyanamide, fulminic acid and metal carbides.
The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.
