corresponding to but slightly greater than the diameter of the
piston for slidably supporting said piston." As the examiner
has correctly noted, these recitations "read on" the
arrangement illustrated in Fig. 3 of Sakazume wherein the
first bore is the groove 13 and the flange is that portion of
the cylinder wall which is between seal 14 and the wiper seal
16. We also observe that the above-noted limitations are
readable on the structure of Sakazume's Fig. 3 wherein the
left-hand portion of cylinder wall is the bore (which is
clearly depicted as having a greater diameter that the
remainder of the cylinder wall) and the remainder of the
cylinder wall (i.e., the right-hand portion) is the flange.
In fact, the terminology of representative claim 1 is so broad
that the bore and flange could even be of the same diameter
(e.g., wherein both the bore and flange have a diameter that
is "slightly greater" than the diameter of the piston).
As to the appellant's contention that the claimed bore
and flange arrangement allows the piston to pivot about the
flange, this argument is simply not commensurate in scope with
the claimed subject matter inasmuch as no pivoting movement
has been claimed. It is well settled that features not
