Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
71 words
A single electrical conducting cable comprising: (a) a conductive core having solid one-piece terminal lugs at each end, wherein said lugs comprise an oxidation resistant alloy; (b) a single gas impermeable sheath comprising an oxidation resistant alloy and having an inner surface and an outer surface, the outer surface of which is hermetically sealed using a heat resistant braze to each of the terminal lugs, thereby entirely encasing the conductive core.
Claim 2
Dependent Claim
71 words
A single electrical conducting cable comprising: (a) a conductive core having solid one-piece terminal lugs at each end, wherein said lugs comprise an oxidation resistant alloy; (b) a single gas impermeable sheath comprising an oxidation resistant alloy and having an inner surface and an outer surface, the outer surface of which is hermetically sealed using a heat resistant braze to each of the terminal lugs, thereby entirely encasing the conductive core.
Claim 3
Dependent Claim
18 words
The cable of claim 1 wherein the conductive core comprises copper, nickel, aluminum, or silver, or alloys thereof.
Claim 4
Dependent Claim
11 words
The cable of claim 2 wherein the conductive core comprises copper.
Claim 5
Dependent Claim
18 words
The cable of claim 1 wherein the sheath is flexible and comprises a corrugated metal resistant to oxidation.
Claim 6
Dependent Claim
13 words
The cable of claim 4 wherein the corrugated metal comprises a stainless steel.
Claim 7
Dependent Claim
60 words
An electrical conducting cable consisting essentially of: (a) a conductive core having solid one-piece terminal lugs at each end; (b) a single gas impermeable sheath having an inner surface and an outer surface, the outer surface of which is hermetically sealed to each of the terminal lugs, wherein the sheath is flexible and comprises a corrugated metal resistant to oxidation.
Claim 8
Dependent Claim
60 words
An electrical conducting cable consisting essentially of: (a) a conductive core having solid one-piece terminal lugs at each end; (b) a single gas impermeable sheath having an inner surface and an outer surface, the outer surface of which is hermetically sealed to each of the terminal lugs, wherein the sheath is flexible and comprises a corrugated metal resistant to oxidation.
Claim 9
Dependent Claim
18 words
The cable of claim 6 wherein the conductive core comprises copper, nickel, aluminum, or silver, or alloys thereof.
