board for controlling the speed of a motor. While there is
some ancillary heating taking place, it is the overheating of
the porcelain enamel metal substrate which becomes important
to Yamamoto as this occurrence is used to trip a temperature
fuse and break the resistance circuit. The porcelain enamel
metal substrate of Yamamoto is not being used to purposely
provide heat to another element, i.e., the fragrance bar, as
claimed, and we find nothing within the disclosures of Pons
Pons and Yamamoto which would have led the artisan to employ
the porcelain enamel metal substrate of Yamamoto as a heating
element in Pons Pons to heat the fragrance bar 2 of Pons Pons.

1, 5, 7, 8, 11 through 15 and 17 through 19 under 35 U.S.C. §
103 wherein Yamamoto is used as a basis for the rejection.
We reach varied, sometimes opposite, results with regard

for Yamamoto.
Hedden clearly teaches that a porcelain enamel metal
substrate may be employed as a heating panel to generate
