DEFINITION

Classification: 417/199.1

DIVERSE PUMPS:

(under the class definition) Apparatus comprising a plurality of discrete pumps of different basic types.

(1) Note. This definition does not include a plurality of pumps of different basic types if one is a mere auxiliary or ancillary of the other (e.g., lubricant or cooling water or condensate removal pump for main pump).

(2) Note. This definition includes diverse pumps wherein one of the pumps is disclosed merely as priming another, the priming pump in this instance not being considered merely ancillary to the other pump.

(3) Note. Mere difference in size or shape, etc., of the same basic type of pump is not included under this definition.

(4) Note. The following are exemplary of different basic types of pumps: (a) Rotary expansible chamber; (b) Rotary nonexpansible chamber; (c) Reciprocating working member (piston or cylinder); (d) Collapsible chamber (e.g., diaphragm, bellows); and (e) Hydraulic ram.

(5) Note. A patent will be classified as an original in this or indented subclasses if the pumps are disclosed as diverse, but a claim recites only one of the pumps specifically. On the other hand a plurality of pumps which are disclosed as diverse but are claimed broadly will not be classified as an original under the definition.

76+, for jet pumps with motive fluid generating pumps.

85+, for diverse pumps at least one of which is of the type in which fluid is pumped by contact or entrainment with another.
