Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
70 words
An electrical network comprising: a metal carrier; a pair of insulating layers materially bonded to opposite sides of said carrier, said insulating layers being temperature resistant up to at least 200° C.; a nickel/chromium resistance layer, conductive paths and terminal elements materially bonded to said insulating layers, said terminal elements located adjacent an edge of the network contacting said conductive paths; and a copper layer carried on said resistance layer.
Claim 2
Dependent Claim
70 words
An electrical network comprising: a metal carrier; a pair of insulating layers materially bonded to opposite sides of said carrier, said insulating layers being temperature resistant up to at least 200° C.; a nickel/chromium resistance layer, conductive paths and terminal elements materially bonded to said insulating layers, said terminal elements located adjacent an edge of the network contacting said conductive paths; and a copper layer carried on said resistance layer.
Claim 3
Dependent Claim
26 words
The electrical network of claim 1, comprising: a lacquer covering at least one surface of said carrier and carrying said resistance layer and the conductive elements.
Claim 4
Dependent Claim
16 words
The electrical network of claim 1, wherein said terminal elements are soldered to said conductive paths.
Claim 5
Dependent Claim
29 words
The electrical network of claim 1, wherein said carrier includes plugs projecting therefrom one of, said insulating layer covering said plugs and carrying at said plugs, said terminal elements.
Claim 6
Dependent Claim
23 words
The electrical network of claim 4, wherein said terminal elements have distant ends which are spaced from the distant ends of said plugs.
Claim 7
Dependent Claim
34 words
The electrical network of claim 4, wherein one said insulating layer extends about all sides of said plugs and said terminal elements extend over a surface and the two adjacent edges of respective plugs.
Claim 8
Dependent Claim
11 words
The electrical network of claim 1, wherein said carrier comprises aluminum.
Claim 9
Dependent Claim
11 words
The electrical network of claim 1, wherein said carrier comprises steel.
Claim 10
Dependent Claim
45 words
The electrical network of claim 1, wherein said carrier comprises a solderable metal, and said insulating layers are formed of a single layer folded about said carrier, and metal layers on the surfaces of said insulating layer, one of which is soldered to said carrier.
Claim 11
Dependent Claim
55 words
The electrical network of claim 1, wherein said insulating layers are formed of a continuous layer folded about said carrier and which carries said resistance layer and the conductive elements on one surface and carries a solderable metal layer on its other surface which extends about and is soldered to both surfaces of said carrier.
