show the "obtuse angle" recited in claim 51. In particular,
we do not see the two sides of the angle ? in the appellants'
Exhibit A. Claim 51 states "the yarn extends at an obtuse
angle from the inner edge of the endless belt". Thus, angle ?
in Fig. 6 of the appellants' Exhibit A should extend between
two sides, the yarn (15) and the inner edge of the endless
belt, as recited in claim 51. But in the appellants' Exhibit
A each individual yarn 15 is a point, not a side. Moreover,
the arc representing the angle ? is drawn from somewhere
between two yarns, not to a yarn as recited in claim 51. For
these reasons we do not see that the obtuse angle of claim 51
is shown in Fig. 6 of the appellants' Exhibit A.
There being no other explanation offered, or apparent,
for the "obtuse angle" recited in claim 51, and since our
review of the appellants' drawings and specification does not
reveal to us any basis for the obtuse angle of the individual
yarns as recited in claim 51, we affirm the examiner's
rejection of claim 51 under 35 U.S.C. § 112, first paragraph,
