applying to a gasket a curable silicone resin. The present
specification states the following at page 4:
The curable silicone resin of the
present invention are those resins known in
the art. Silicone resins are highly cross-
linked high molecular weight siloxane systems
and are thus available as powders or flakes
or as solutions in organic solvents.
In addition, the following is stated at page 7 of appellant's
specification:
The curable silicone composition is
applied to the gasket by brushing, dipping,
or spraying. If the resin, catalyst and
lubricant are mixed together without a
solvent, the resulting dry mixture is applied
by dusting the gasket substrate.
Hence, as urged by appellant, it is clear that when the
claimed language "a curable silicone resin" is read in light
of the present specification, the resin is a solid material,
not a liquid one. On the other hand, Viksne discloses a
coating composition for a gasket comprising polymeric
fluorocarbon particles dispersed in a saturant, which saturant
is absorbed in a resilient material of the gasket, "leaving a
sealant coating 15 of polymeric fluorocarbon on the surface of
the resilient material 14" (column 3, lines 23-25). The
