Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
30 words
The flat cable of claim 1 in which said polymeric material-containiNg ribs (b) are equidistantly spaced along the width of said surface of said first layer (a) containing polymeric material.
Claim 2
Dependent Claim
152 words
The flat cable of claim 1 in which said first layer (a) containing polymeric material is entirely polymeric material and in which said polymeric material-containing ribs (b) are polymeric material ribs covered on their tops and sides with a layer of metal conductor which also covers the bottoms of grooves (c), said grooves (c) also containing metal conductor having a polymeric material layer contacting and encircling said metal conductor, said polymeric material encircled metal conductors running substantially the length of said grooves, and in which said layer (d) containing metal conductor is made up of a second layer of polymeric material covering said polymeric material-containing ribs (b) at the ends of said ribs opposite to those contacting said first layer (a) of polymeric material, said second layer of polymeric material being covered with a layer of metal conductor on its surface which is opposite to that contacting said polymeric material-containing ribs (b).
Claim 3
Dependent Claim
117 words
The flat cable of claim 1 in which said first layer (a) containing polymeric material is entirely polymeric material, in which said polymeric material-containing ribs (b) are polymeric material ribs covered on their sides with a layer of metal conductor which also covers the bottoms of grooves (c), said grooves (c) also containing metal conductor having a polymeric material layer contacting and encircling said metal conductor, said polymeric material-encircled metal conductors running substantially the length of said grooves, and in which said layer (d) containing metal conductor is a layer of metal conductor covering said polymeric material-containing ribs (b) at the ends of said ribs (b) opposite to those contacting said first layer (a) containing polymeric material.
Claim 4
Dependent Claim
151 words
The flat cable of claim 1 in which said first layer (a) containing a polymeric material is a layer of polymeric material with a layer of metal conductor covering the surface of said layer of polymeric material opposite to the surface of said layer of polymeric material contacting said polymeric material-containing ribs (b), in which said polymeric material-containing ribs (b) are polymeric material, in which said grooves (c) containing metal conductor contain metal conductor running substantially the length of said grooves, and in which the layer (d) containing metal conductor is made up of a second layer of polymeric material covering said polymeric material-containing ribs (b) at the ends of said ribs (b) opposite to those contacting said first layer of polymeric material, said second layer of polymeric material being covered with a layer of metal conductor on its surface which is opposite to that contacting said polymeric material-containing ribs (b).
Claim 5
Dependent Claim
118 words
A flat cable which comprises a. a first layer of polymeric material having a layer of metal conductor covering one surface, b. ribs of polymeric material spaced along the width of the opposite surface of said first layer (a) running the length of said surface, c. grooves on said surface formed by said ribs, said grooves having, alternately, (1) only metal conductor running substantially the length of said grooves, and (2) metal conductor with a polymeric material layer contacting and encircling said metal conductor running substantially the length of said grooves, and d. a layer of metal conductor covering said ribs on the ends of said ribs opposite to those contacting said first layer (a) of polymeric material.
Claim 6
Dependent Claim
128 words
A flat cable which comprises a. a first layer of polymeric material having a layer of metal conductor covering one surface, b. ribs of polymeric material spaced along the width of the opposite surface of said first layer (a) running the length of said surface, c. grooves on said surface formed by said ribs, said grooves containing metal conductor running substantially the length of said grooves, aNd d. a layer containing metal conductor covering said ribs on the ends of said ribs opposite to those contacting said first layer (a) of polymeric material such that said layer containing metal conductor has a layer of polymeric material covering alternating grooves and a layer of metal conductor covering the alternating layers of polymeric material plus the rest of the grooves.
