Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
A method of forming coaxial transmission lines of small diameters comprising an outer conductor, an inner conductor and dielectric between the conductors, comprising: providing a metal tape; applying longitudinally extending, spaced strips of dielectric to one surface of said tape and in parallel relation to the side edges thereof; converting the tape to tubular form with the dielectric strips on the inner sUrface thereof, the side edges of said tape being adjacent each other to form a longitudinally extending slit, introducing a longitudinally extending inner conductor within said tubular outer conductor by way of said slit, sealing the adjacent edges of said tubular outer conductor together, and deforming the assembled outer conductor to a selected cross-sectional configuration, the spacing between the strips being no greater than the diameter of the inner conductor.
Claim 2
Independent Claim
132 words
A method of forming coaxial transmission lines of small diameters comprising an outer conductor, an inner conductor and dielectric between the conductors, comprising: providing a metal tape; applying longitudinally extending, spaced strips of dielectric to one surface of said tape and in parallel relation to the side edges thereof; converting the tape to tubular form with the dielectric strips on the inner sUrface thereof, the side edges of said tape being adjacent each other to form a longitudinally extending slit, introducing a longitudinally extending inner conductor within said tubular outer conductor by way of said slit, sealing the adjacent edges of said tubular outer conductor together, and deforming the assembled outer conductor to a selected cross-sectional configuration, the spacing between the strips being no greater than the diameter of the inner conductor.
Claim 3
Dependent Claim
14 words
A method as in claim 1 wherein the outer conductor is corrugated transversely thereof.
Claim 4
Dependent Claim
31 words
A method as in claim 1 wherein a low-melting-point synthetic resin is applied to the outer surface of said tape to provide means for sealing the seam in the outer conductor.
