Appeal No. 95-1711
Application No. 08/063,819
The subject matter on appeal is directed to a process of
degating molded parts by the steps of molding, cooling, and
applying an impact to a solid configuration of molding
material comprising parts secured to a runner system by gates,
wherein the gates have a cross-section subtaintially smaller
then any cross-section of the molded configuration.
With respect to his obviousness rejection of the appealed
claims, the examiner broadly contends that it is well known
and conventional to freeze and impact to remove flash in the
molding art. To support this contention the examiner cites
Jones as disclosing the removal of flash by cooling with
liquid nitrogen and tumbling to apply impact. Thus, according
to the examiner, it would have been obvious to one of ordinary
skill in the art at the time of the invention to deflash a
molded article with cryogenic deflashing as described in
Jones.
On the other hand, appellant contends that the removal of
flash as in the Jones process has nothing whatsoever to do
with degating, the subject matter of the appealed claims.
Thus the appealed claims require inter alia, cooling and
application of impact (e.g. tumbling) to a specific solid
