compositions concurrently with molding, as contrasted to the
prior art processes discussed in appellants' specification.
Itoh also discloses that rubber compounds such as
nitrile rubber and neoprene rubber have a high dielectric loss
factor and are said to be "self-heating." See the reference
at column 2, lines 6 and 7, and lines 62-64. Itoh
alternatively discloses that natural rubber, butyl rubber and
ethylene-propylene rubber, materials which have a relatively
low dielectric loss factor, may be made to be "self-heating"
type materials by the addition of polar radical materials such
as carbon black, stearic acid, sulfur and zinc oxide. See
column 2, lines 64-68 of the reference. At column 1, lines
54-58, Itoh clearly suggests a method for vulcanizing and
molding a rubber compound comprising a step of providing a
rubber compound having a "large dielectric loss factor" for
heating by "high frequency dielectric heating" when supplied
to and maintained within a mold. Although Itoh does not
expressly disclose a specific value
