bottom surface of the flange.
This disclosure indicates that the cross sectional shape
of the ribs or ridges may have elements of arcuate, triangular
and rectangular shapes. We interpret "substantially
triangular" within this context to denote a shape having
sidewalls which are spaced farther apart at the base than at
an apex toward which they converge. The apex of such a
"substantially triangular" shape may be rounded and the
sidewalls of the "substantially triangular" shape may be
either straight or curved and may comprise portions which are
perpendicular to the base and, thus, do not converge toward
the apex. This interpretation is consistent with the
definition "triangular, but possibly with rounded corners, or
possibly with sides that are nearly straight, but somewhat
less than completely straight" urged by appellants on page 8
of the brief.
The ridges illustrated in Figures 4 and 5 of Studer, even
if not perfectly triangular, certainly appear to us to have a
cross-sectional shape which falls within the broad definition
of "substantially triangular" set forth above. Thus, it is
