OPINION
We have carefully considered all of the arguments
advanced by appellants and the examiner and agree with the
examiner that the invention recited in appellants’ claims 3,
4, 6, 7, 9, 13-16, 20-24, 26-28, 30 and 33-35 would have been
obvious to one of ordinary skill in the art at the time of
appellants’ invention over the applied prior art.
Accordingly, we affirm the aforementioned rejection. Under
