Class 417: Pumps
This is the general class for the pumping of fluids, and includes the pumping of slurries, fluent material and the like if handled in a manner not inconsistent with the handling of fluids. A pump is defined as means to move a fluid by taking it from one place or location and moving it to another place or location different from whence it came, the pump, therefore having an inlet and an outlet for the pumped fluid which are separate and distinct. The pumping of the fluid is generally accomplished by action thereon of a mechanical member (eg. piston) or by contact or entrainment with another fluid (eg. jet pumps). Also, the pumping may be accomplished by the direct action on the pumped fluid of an electric or magnetic. This class is the residual home for the formation of a vacuum in an enclosed space by a gettering action; a getter being a material which when placed in an enclosed space reduces the gas or vapor content of the space either by a chemical or physical action. Also, included are those devices and processes in which the fluid is ionized to permit or enhance the gettering action. These devices are often termed "getter-ion pumps".Subclass 355: Pump within rotary working member
Subclass 356: Pump within armature
Subclass 420: Pump magnetically coupled to rotary drive
Subclass 423.1: Rotary motor and rotary nonexpansible chamber pump
Subclass 423.7: With specific motor details
Subclass 423.12: Having bearing
Subclass 423.14: With specific housing details
Subclass 424.1: Supported for rotation on vertical axis
Class 415: Rotary Kinetic Fluid Motors Or Pumps
This is the class for apparatus, and corresponding methods of operating such apparatus, comprising a runner, and in which a working fluid is guided to, around, or from, the runner. A means for guiding or confining, the working fluid must be present. This class includes typically turbines, wind and water wheels, centrifugal pumps and blowers; and such casings, conduits, guide means and other elements peculiar to the subject matter of this class not otherwise classifiable.Subclass 206: Axially directed inlet and tangential outlet
Class 600: SurgerySubclass 16: CARDIAC AUGMENTATION (PULSATORS, ETC.)
Class 623: Prosthesis (I.E., Artificial Body Members), Parts Thereof, Or Aids And Accessories Therefor
This class provides for artificial substitutes or parts for a human body particularly manufactured or adapted to replace or assist a missing or defective natural body member or part thereof for functional or cosmetic reasons. It also provides for elements or accessories for substitutes or parts of this class unless such elements or accessories are of such general utility as to be provided for in some other class. This class also provides for devices and mechanisms designed to operate or control artificial substitutes or parts for a human body, including methods of operating an artificial heart.
Class 416: Fluid Reaction Surfaces (I.E., Impellers)
This class provides the locus for all fluid impellers not elsewhere classifiable. The working fluid, which is acted on by or acts upon the impeller, may be a liquid or gas.Subclass 186R: Having opposed annular surface between adjacent blades
Class 310: Electrical Generator Or Motor Structure
This is the residual class for all subject matter, not elsewhere classified, relating to electrical generator or motor structure.Subclass 90.5: Magnetic bearing
