DEFINITION

Classification: 60/685

(under the class definition) Apparatus of a motor and exhaust system with means affecting the fluid after its exhaust from the motor.

(1) Note. Exhaust fluid is considered to be the fluid that has left the final means that could extract power from the fluid and that has reached a point where its affect cannot affect operation of the power extraction means. For an elaboration of this line see the statement in (4) Note, section B, paragraph (5) of the class definition of Class 91, and paragraph (7) of the Search Class note to Class 60, in

the definition of Class 415.

(2) Note. Fluid flowing between serially connected motors or motor stages is not considered to be exhaust fluids. See subclass 684, of this class and the search notes to its definition.

SEE OR SEARCH THIS CLASS, SUBCLASS:

39.5, for the treatment of the exhaust of a motor in which externally generated combustion products are used as motive fluid.

200+, for a power plant, the exhaust of which is the jet of a reaction motor. 272, for an internal combustion engine with means treating or handling exhaust gas.

325+, for a power system including a pressure fluid source and motor in which the motor exhaust is generally pressurized by a pump to be redelivered to the motor.

595, for a motor driven by the exhaust of a free piston type of internal combustion engine.

597+, for a motor driven by the waste heat or exhaust energy from an internal combustion engine.

642+, for a power plant energized by externally applied heat in which the motor exhaust is condensed or cooled.

110, Furnaces, appropriate subclasses for the utilization of motor exhaust steam in a furnace, particularly

203+, for using exhaust steam to promote combustion in the firebox and subclasses 119+ and 147+ for using exhaust fluid as a means to produce a draft in the smokebox of the furnace.

122, Liquid Heaters and Vaporizers, particularly

412+, for boiler feed water heated by exhaust fluid.

181, Acoustics,

213, for jet engine type mufflers, per se, and subclass 220 for ground based fluid treatment of jet engine exhaust. 415, Rotary Kinetic Fluid Motors or Pumps,

182.1+, for rotary kinetic fluid motors having motive fluid exhaust passages provided with means to simply guide, by means of vanes or conduits, the flow of motive fluid immediately after being discharged from the runner and within

the area where the fluid could affect the operation of the motor (e.g., by affecting back pressure on the runner).
