DECISION

1
James E. Dore and Jerry W. Brockmeyer appeal from a final decision of the United States Patent and Trademark Office Board of Patent Appeals and Interferences (board), appeal no. 679-94, affirming a rejection under Section 103 of claims 1-3 in their pending application.  We affirm.

OPINION

2
Appellants have not established that the board erred in holding that it would have been obvious to:  (1) replace the seal in the molten metal filter of Yarwood or Narumiya with the intumescent seal of Foster in Foster's high temperature environment;  and (2) preheat the filter to improve sealing as taught by Brockmeyer.  35 U.S.C. Sec. 103 (1982).
