Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A coaxial electric signal cable comprising: (a) a core consisting of a metal center conductor surrounded by a first layer of tape-wrapped expanded polytetrafluoroethylene insulation, then a second layer of polymeric insulation, wherein the second layer of insulation is in intimate contact with, but not adhered to, the first layer; (b) a conductive metal drain wire arranged parallel to said core; (c) an outer conducting layer surrounding said core and said drain wire, comprising a helically-wrapped metal-coated polymer tape, metal side contacting said drain wire, and having a strip of heat-sealable adhesive on an edge of said tape on the same side of the tape as that bearing said metal; and (d) a protective jacket; wherein the outer portion of said first layer of insulation is sintered to thermoset after wrapping.
Claim 2
Dependent Claim
131 words
A coaxial electric signal cable comprising: (a) a core consisting of a metal center conductor surrounded by a first layer of tape-wrapped expanded polytetrafluoroethylene insulation, then a second layer of polymeric insulation, wherein the second layer of insulation is in intimate contact with, but not adhered to, the first layer; (b) a conductive metal drain wire arranged parallel to said core; (c) an outer conducting layer surrounding said core and said drain wire, comprising a helically-wrapped metal-coated polymer tape, metal side contacting said drain wire, and having a strip of heat-sealable adhesive on an edge of said tape on the same side of the tape as that bearing said metal; and (d) a protective jacket; wherein the outer portion of said first layer of insulation is sintered to thermoset after wrapping.
Claim 3
Dependent Claim
25 words
A cable of claim 1 wherein the radial thickness of said first layer is such that high-density termination to a multiconnector pin may be accomplished.
Claim 4
Dependent Claim
30 words
A cable of claim 1 wherein the radial thickness of said second layer is such that the required impedance and capacitance values are achieved between said inner and outer conductors.
Claim 5
Dependent Claim
59 words
A cable of claim 1 wherein said metal on said metal-coated polymer tape partially covers one side of said polymer tape to leave a continuous strip of metal-free tape adjacent said metal layer and said heat-sealable adhesive is applied to said tape on the same side as said metal layer on the edge of said strip which is metal-free.
Claim 6
Dependent Claim
21 words
A cable of claim 4 wherein said heat-sealable adhesive is applied to the opposite side of said tape as said metal.
Claim 7
Dependent Claim
12 words
A cable of claim 4 wherein said adhesive is a heat-sealable thermoplastic.
Claim 8
Dependent Claim
14 words
A cable of claim 1 wherein said drain wire is helically-wrapped around said core.
Claim 9
Dependent Claim
34 words
A cable of claim 1 wherein the metals of said signal conductor, said drain wire, and said outer conductor are selected from the group consisting of copper, metal plated copper, copper alloys, and aluminum.
Claim 10
Dependent Claim
12 words
A cable of claim 1 wherein said metal-coated polymer tape comprises polyester.
