Opinions

KIRKPATRICK, Judge.

This appeal is from the decision of the Board of Appeals affirming the examiner’s rejection of claims 6, 8 and 14-17 in appellants’ patent application1 entitled “Apparatus for Making Foams” as being “unpatentable over the prior art.”

[457] The application relates to apparatus designed to effect rapid mixing of reactive liquid chemicals. After mixing, the partially reacted liquid (which may consist of a polyester, a diisocyanate and an aqueous amine catalyst) is ejected from the apparatus into a suitable mold, where further reaction between the chemicals causes foaming and curing of the material to form, for example, a porous solid polyurethane product. Appellants’ apparatus is best understood with reference to Figure 2 of their application drawings:
