Appeal No. 1997-3515
Application No. 08/390,226
As pointed out above, claim 20 calls for the magnetic
drive unit to be outside the housing and effect rotation
through the wall of the housing without mechanical coupling
with the rotatable pallet. However, in the Kemmerer
arrangement, the entire magnetic drive system is located
inside the housing. This being the case, the reference would
not have suggested the claimed structure to one of ordinary
skill in the art. Consideration of the teachings of the other
references applied against claim 20, which have been discussed
above, does not alter this conclusion.
