is precisely what is required by claim 82. Since a characteristic of such pumps is to
provide a largely pulsatile or periodic unsteady flow, this combination of references also
renders the subject matter of claim 83 obvious. Finally, contrary to the appellants’
assertions on page 8 of the Brief, claim 84 requires not that the pump provide a steady
flow, but “a largely steady flow” (emphasis added). Since the appellants have not
pointed out a specific definition of this terminology, in which they utilize a term of
degree, it is our view that the adjustable and variable operation and controls disclosed
by Wallach would enable the pump to provide a flow that meets this condition. The
rejection of claim 84 also is sustained.
SUMMARY
Both of the rejections are sustained.
The decision of the examiner is affirmed.
