Appeal No. 98-1292
Application No. 08/570,835
tightly against the support plate. To replace the disclosed
groove with one in which the cross-section is toroidal would
destroy this teaching and, again, operate as a disincentive to
the artisan to make the proposed modification. In this
regard, we note that the reason for the structure claimed by

references.
The rejection is not sustained.
The decision of the examiner is reversed.
