Appeal No. 2003-0132
Application 09/741,356
On page 1 of the specification, appellants note that the
field of the invention relates to devices that meter and dispense
singular and plural component liquids and solids (e.g., powders).
More particularly, appellants identify as a first aspect of the
invention (specification, page 5), a dispensing system including
a valved nozzle to dispense material from a progressive cavity
pump, wherein the nozzle does not directly control the pump.
Rather, a pressure sensor located downstream from the progressive
cavity pump senses flow pressure in the system, which pressure is
impacted upon by operation of the remote nozzle, and a controller
responds to the pressure build-up or decay and controls the pump
accordingly. Independent claims 1 and 9 are representative of
the subject matter on appeal and a copy of those claims can be
found in the Appendix to appellants’ brief.
As set forth on page 3 of the answer, the patents
purportedly relied upon by the examiner in rejecting the appealed
claims are:
Suh et al. (Suh) 4,170,319 Oct. 9, 1979
Cline et al. (Cline ‘686) 5,992,686 Nov. 30, 1999
