Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
74 words
An assembly comprising two members, at least one of which is ceramic, bonded together by a layer of resilient heat-resistant laminated composite consisting essentially of a plurality of layers of woven graphite cloth bonded together by silicone rubber, said composite containing from about 60% to 90% by volume of said woven graphite cloth and the remainder of said silicone rubber and having resiliency above the temperature at which the silicone rubber loses its resiliency.
Claim 2
Dependent Claim
74 words
An assembly comprising two members, at least one of which is ceramic, bonded together by a layer of resilient heat-resistant laminated composite consisting essentially of a plurality of layers of woven graphite cloth bonded together by silicone rubber, said composite containing from about 60% to 90% by volume of said woven graphite cloth and the remainder of said silicone rubber and having resiliency above the temperature at which the silicone rubber loses its resiliency.
Claim 3
Dependent Claim
42 words
An assembly as set forth in claim 1 wherein said cloth has a thickness of from 15 to 20 mils and wherein there are from about four to six layers of said cloth for each about one-eighth inch thickness of said composite.
Claim 4
Dependent Claim
21 words
An assembly as set forth in claim 1 wherein the silicone rubber does not completely fill the layers of the cloth.
Claim 5
Dependent Claim
66 words
An assembly comprising two members having therebetween and in contact therewith a resilient heat-resistant laminated composite consisting essentially of a plurality of layers of graphite cloth bonded together by silicone rubber, said composite containing from about 60% to 90% by volume of said graphite cloth and the remainder of said silicone rubber and having resiliency above the temperature at which the silicone rubber loses its resiliency.
Claim 6
Dependent Claim
66 words
An assembly comprising two members having therebetween and in contact therewith a resilient heat-resistant laminated composite consisting essentially of a plurality of layers of graphite cloth bonded together by silicone rubber, said composite containing from about 60% to 90% by volume of said graphite cloth and the remainder of said silicone rubber and having resiliency above the temperature at which the silicone rubber loses its resiliency.
Claim 7
Dependent Claim
15 words
An assembly as set forth in claim 4 wherein said cloth is of woven construction.
Claim 8
Dependent Claim
47 words
An assembly as set forth in claim 4 wherein each of said cloth layers has a thickness of from about 15 to 20 mils and wherein the composite has from about four to six layers of the cloth for each about one-eighth inch thickness of said composite.
