Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
Tensile support member for use in a cryogenic environment, comprising: an endless link formed of an epoxy glass laminate with at lease one ply of said laminate having fibers aligned circumferentially about said link; and at least one intermediate heat sink positioned on one side of said link between couplings of said link, said heat sink including at least one heat conductive metal strip contained within the plies of said laminate and extending out therefrom to form a heat conductive path.
Claim 2
Dependent Claim
81 words
Tensile support member for use in a cryogenic environment, comprising: an endless link formed of an epoxy glass laminate with at lease one ply of said laminate having fibers aligned circumferentially about said link; and at least one intermediate heat sink positioned on one side of said link between couplings of said link, said heat sink including at least one heat conductive metal strip contained within the plies of said laminate and extending out therefrom to form a heat conductive path.
Claim 3
Dependent Claim
57 words
Tensile support member for use in a cryogenic environment, comprising: an endless link formed of an epoxy laminate with at least one ply of said laminate having fibers aligned circumferentially about said link; and at least one spherical bearing having a race riding on a spherical bearing, one end of said link being wrapped about said race.
Claim 4
Dependent Claim
57 words
