Appeal No. 95-1987
Application 08/076,475
utilizing a "high frequency" dielectric heating technique. In
the "Description of the Prior Art" section of appellants'
specification, at page 3, appellants acknowledge that rubber
compounds have been vulcanized using UHF (ultra high fre-
quency) dielectric heating. However, in such processes,
appellants indicate that vulcanizing and molding must be
carried out separately. According to appellants, the rubber
compounds utilized in such prior art processes possess a
relatively low dielectric loss factor which necessitates the
use of ultra high frequency as predicted by the well-known
heating rate equation. Generally see the specification at
page 3 and the specification at page 1, line 32, through page
3, line 1.
Appellants' invention involves the preparation of a
rubber compound having a dielectric loss factor of more than
0.20 which enables appellants' process to accomplish "high
frequency dielectric heating at a frequency less than 100
MHZ." Thus, in an apparent reference to calculations made
using the well-known heating rate equation, appellants state
in their specification at page 9, lines 33-38, that:
