Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A method of making fuses for a record unit comprising, first providing on an insulated substrate an electrical circuit pattern with which a plurality of fuses are to be connected, next providing a groove in said substrate in an area where said fuses are to be located, next attaching each end of a plurality of fine wires to said electrical circuit pattern, said fine wires crossing said groove in said substrate, next covering the attached ends of said fine wires with a first coating, next masking the uncovered portion of said fine wires with a flexible material, and then encapsulating said fine wires and said first coating with a second coating whereby said flexible material prevents said second coating from individually encapsulating said fine wires and prevents said second coating from entering said groove.
Claim 2
Independent Claim
134 words
A method of making fuses for a record unit comprising, first providing on an insulated substrate an electrical circuit pattern with which a plurality of fuses are to be connected, next providing a groove in said substrate in an area where said fuses are to be located, next attaching each end of a plurality of fine wires to said electrical circuit pattern, said fine wires crossing said groove in said substrate, next covering the attached ends of said fine wires with a first coating, next masking the uncovered portion of said fine wires with a flexible material, and then encapsulating said fine wires and said first coating with a second coating whereby said flexible material prevents said second coating from individually encapsulating said fine wires and prevents said second coating from entering said groove.
Claim 3
Dependent Claim
48 words
A method of making fuses for a record unit as set forth in claim 1 wherein said electrical circuit pattern is etched from a sheet of electrical conductive material bonded to said substrate and includes a common terminal to which one end of each fine wire is attached.
Claim 4
Dependent Claim
24 words
A method of making fuses for a record unit as set forth in claim 1 wherein said fine wire is 0.4 mil platinum wire.
Claim 5
Dependent Claim
30 words
A method of making fuses for a record unit as set forth in claim 1 wherein said first coating is epoxy and is cured by heating at an elevated temperature.
Claim 6
Dependent Claim
30 words
A method of making fuses for a record unit as set forth in claim 1 wherein said second coating is epoxy and is cured by heating at an elevated temperature.
Claim 7
Dependent Claim
22 words
A method of making fuses for a record unit as set forth in claim 1 wherein said flexible material is adhesive-backed paper.
