| DefinitionThis is the residual class concerned with the driving of a load by the conversion of heat, pressure, radiant, or gravitational energy into mechanical motion. It includes a motor in combination with its energy supply or its exhaust treatment. It also includes the motors, per se, combinations of motors, and elements specialized for use in such energy conversion that are not specifically provided for elsewhere. (1) Note. The mere nominal inclusion with the motor of and element or machine driven by the motor is not generally considered sufficient to exclude the patent from the class. | Lines with other classes and within this classUnless specifically provided for elsewhere, a combination of plural motors of types that would, per se, be classified in different classes is classified in Class 60. Combustion products generators in which steam or water are added to the combustion zone are classified in Class 60, Power Plants, where it is the sole disclosure that the products of combustion are to be used to produce useful work. See Class 110, Furnaces, and Class 431, Combustion, for combustion products generators of general utility where steam or water is supplied to the combustion zone. Combustion products generators, per se, using solid fuel, having high pressure generator structure peculiar to the generation of high pressure fluid for motive power, are classified herein. Combustion chamber structure of general utility, and structure for fuel preparation and fuel feeding to a conventional combustion chamber not provided for in other fuel preparation classes, as Class 241, Solid Material Comminution or Disintegration, are classified in Class 110, Furnaces. Combustion product generators in which hazardous or toxic waste is used as the fuel to produce useful work. See Class 588, Hazardous or Toxic Waste Destruction or Containment, subclasses 300-415 and 249-260 for the processes of chemical destruction or containment of hazardous or toxic waste. LINE WITH CLASS 91 AND CLASS 418 See (4) Note of the class definition of Class 91, for a statement of the line between Classes 60 and 91, the same line being maintained between Classes 60 and 418. |
