Abstract
Abstract A capacitive network particularly suited for radio frequency shielding is formed as a layer or stack type condenser having a gap cut therein normal to the planes of the layers to divide the structure into stack portions. Adjacent groups of dielectric and metallic coating layers form ranges of capacitance wherein each range includes internal series capacitive circuits interconnected by bridging coatings between the stack sections in accordance with desired capacitance circuit configurations.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
A method of making capacitive networks comprising the steps of metallizing a dielectric tape with patterns of metallic coatings some of which extend to a first edge of the tape and others of which extend to the second edge of the tape, overlappingly winding the tape on a drum, applying metallic frontal contact layers to the wound edges of the tapes to contact the respective metallic coatings at the edges, adhering contact wires at points along the frontal layers, severing the wire and severing part way through the wound tape between points on the first edge of the wound tape, and severing the wire on the second edge and severing the entire tape to form individual capacitor networks with leads attached.
Claim 2
Independent Claim
121 words
A method of making capacitive networks comprising the steps of metallizing a dielectric tape with patterns of metallic coatings some of which extend to a first edge of the tape and others of which extend to the second edge of the tape, overlappingly winding the tape on a drum, applying metallic frontal contact layers to the wound edges of the tapes to contact the respective metallic coatings at the edges, adhering contact wires at points along the frontal layers, severing the wire and severing part way through the wound tape between points on the first edge of the wound tape, and severing the wire on the second edge and severing the entire tape to form individual capacitor networks with leads attached.
Claim 3
Dependent Claim
32 words
A method according to claim 1, wherein, further defined by winding a plurality of metallized tapes in superposition, and metallically coating, adhering and severing with respect to all of the wound edges.
Claim 4
Dependent Claim
48 words
The method according to claim 1, wherein the step of adhering contact wires includes the step of individually adhering U-shaped contact wires on the frontal layer on the first edge of the tape and the step of severing the wire is further defined as bisecting the U-shaped wires.
