Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A gasket material comprising a base material having an elastomeric bead bonded to localized areas thereof and projecting outwardly of the plane of said base material, said base material being of substantially uniform thickness and composed of a fibrous composition containing from about 10 percent up to about 100 percent by weight of a fibrous reinforcing agent, said base material further characterized as having a compressibility of from about 2 percent to about 60 percent and adapted to transmit a compressive load applied to said bead to the opposite face of said base material over an area approximately equal to the area of said bead, said bead composed of a deformable elastomeric material and adapted to be deformed when disposed in sealing engagement between the flanges of a connection.
Claim 2
Dependent Claim
129 words
A gasket material comprising a base material having an elastomeric bead bonded to localized areas thereof and projecting outwardly of the plane of said base material, said base material being of substantially uniform thickness and composed of a fibrous composition containing from about 10 percent up to about 100 percent by weight of a fibrous reinforcing agent, said base material further characterized as having a compressibility of from about 2 percent to about 60 percent and adapted to transmit a compressive load applied to said bead to the opposite face of said base material over an area approximately equal to the area of said bead, said bead composed of a deformable elastomeric material and adapted to be deformed when disposed in sealing engagement between the flanges of a connection.
Claim 3
Dependent Claim
23 words
The gasket material as defined in claim 1, wherein the projecting surface of said bead is provided with an arcuate cross sectional contour.
Claim 4
Dependent Claim
35 words
The gasket material as defined in claim 1, wherein the projecting height of said bead relative to the thickness of said base material is within a ratio of from about 1/2 :1 to about 10:1.
Claim 5
Dependent Claim
33 words
The gasket material as defined in claim 1, wherein said base material is formed with an aperture therethrough and said bead is continuous and is disposed adjacent to the edge of said aperture.
Claim 6
Dependent Claim
18 words
The gasket material as defined in claim 1, wherein said bead is composed of an oil-resistant elastomeric material.
Claim 7
Dependent Claim
17 words
The gasket material as defined in claim 1, wherein said bead is comprised of a polyurethane elastomer.
