application, stands withdrawn from consideration. Claim 12 is
illustrative:
12. A method of manufacturing a coated precision metal
part, said method comprising preliminarily heat treating a
metal part at a first temperature cycle sufficient to effect
dimensional distortion thereof, conforming the preliminarily
heat treated metal part to a dimension, forming a metal
coating on a [sic] least a portion of the conformed metal
part, and secondarily heat treating the coated conformed metal
part at a second temperature cycle insufficient to effect
significant dimensional distortion thereof, whereby the
secondarily heat treated metal part conforms to said
dimension.
The examiner relies upon the following reference as
evidence of obviousness:
Lancsek 4,859,494 Aug. 22, 1989
Appellant's claimed invention is directed to a method of
making a coated precision metal part, such as a combing roll.
The method entails subjecting the metal part to a preliminary
heat treatment which effects dimensional distortion of the
metal part, conforming the heat-treated metal part to a
dimension, such as by machine, forming a metal coating on the
machined metal part, and subjecting the coated metal part to
second heat treatment which does not distort the dimension of
the metal part. According to appellant, "by pre-heat treating
the assembled or unassembled parts prior to precision
