## Opinion text

MARTIN, Judge
(dissenting).
I disagree with the majority because I believe that one skilled in this art who wanted to manufacture a hollow generally conical-shaped article having a tapered side by means of the axial displacement procedure, would know that a tapered blank should be used and that the path of the roller should not be parallel to the spindle. I find nothing else in this application upon which patentability can be predicated.
