Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
A porous metal, fluid cooled, electrical conductor comprising spirally wound electrically conductive porous metal sheet; means for introducing and removing electrical current joined to each end of such wound metal sheet; fluid impermeable, electrically nonconductive means disposed on at least the outer surface of said wound metal sheet; and fluid conduit means disposed at each end of said wound metal sheet arranged to introduce cold fluid at one end and discharge warmed fluid at the other end of said warmed porous metal sheet after flow therethrough.
Claim 2
Dependent Claim
86 words
A porous metal, fluid cooled, electrical conductor comprising spirally wound electrically conductive porous metal sheet; means for introducing and removing electrical current joined to each end of such wound metal sheet; fluid impermeable, electrically nonconductive means disposed on at least the outer surface of said wound metal sheet; and fluid conduit means disposed at each end of said wound metal sheet arranged to introduce cold fluid at one end and discharge warmed fluid at the other end of said warmed porous metal sheet after flow therethrough.
Claim 3
Dependent Claim
24 words
A conductor as described in claim 1 wherein the wound metal sheet has a void space range of about 50 to 95 percent void.
Claim 4
Dependent Claim
16 words
A conductor as described in claim 1 wherein the porous metal sheet comprises metal screen wire.
Claim 5
Dependent Claim
19 words
A conductor as described in claim 1 wherein the wound porous metal sheet has a longitudinally varying cross-sectional area.
Claim 6
Dependent Claim
19 words
A conductor as described in claim 1 wherein the wound porous metal sheet has a longitudinally constant cross-sectional area.
Claim 7
Dependent Claim
22 words
