combination would have been obvious. We observe that the
continuous process of Crafton does not require the castings to
be "submerged in the fluidized sand" or to maintain the
submerged condition "for a period of time sufficient to
thermally decompose the binder" as recited in appellants'
claim 1 and we conclude that such features would not have been
obvious at the time the invention was made to a person having
ordinary skill in the art.
For these reasons, we shall not sustain the standing
35 U.S.C. ' 103 rejection of claim 1, or of claims 2 through
17 and 25 which depend therefrom, as being unpatentable over
Bonnemasou in view of Crafton.
