DEFINITION
Classification: 417/313
(under the class definition) Apparatus claimed in combination with features other than the fluid impelling means or valving, the drive means or casing or support structure for the pump and not provided for in preceding subclasses.
(1) Note. In view of the intimate relationship between Class 92, Expansible Chamber Devices, and this class with respect to nonrotary expansible chamber-type pumps some subjects matter which ordinarily would be considered to be combined when claimed in combination with nonrotary expansible chamber pumps of this class (417) are not considered to be combined herein and are excluded under this definition. The following basis has been used to determine whether certain subject matter is to be considered as combined under this definition. If Class 92 specifically provides a basis of classification for the subject matter of Class 92, then said subject matter combined with a nonrotary expansible chamber pump will be excluded from this definition. The miscellaneous combined subclass of Class 92 (subclass 145) is not considered to specifically provide a basis of classification for any combined device. For
example, a nonrotary expansible chamber pump combined with fluid purifying means as provided for in Class 92 subclasses 78+ or with nonsealing cleaning means as provided for in Class 92 subclass 87 are excluded from this definition.
(2) Note. Note the following subclasses providing for subject matter not considered to be combined under this definition; 496+, 432+, 434, 435, 438, and 493+.
