Abstract
Abstract A method of making an electrical resistance element is disclosed comprising the steps of providing a conductor having a pair of lead attaching ends, forming each lead attaching end with a plurality of spaced and predetermined lead attaching parts therealong, attaching a pair of leads respectively to one preselected lead attaching part of each end of the conductor so that a desired electrical resistance is provided, and completely covering the conductor and part of the leads with an encasing structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
A method of making an electrical element comprising the steps of providing a conductor having a pair of lead attaching ends, forming each lead attaching end with a plurality of spaced and predetermined lead attaching parts therealong, attaching a pair of leads respectively to one preselected lead attaching part of each end of said conductor so that a desired electrical resistance is provided through said conductor between said leads, and completely covering said conductor and part of said leads with an encasing structure whereby the remainder of said leads extend from said encasing structure.
Claim 2
Independent Claim
94 words
A method of making an electrical element comprising the steps of providing a conductor having a pair of lead attaching ends, forming each lead attaching end with a plurality of spaced and predetermined lead attaching parts therealong, attaching a pair of leads respectively to one preselected lead attaching part of each end of said conductor so that a desired electrical resistance is provided through said conductor between said leads, and completely covering said conductor and part of said leads with an encasing structure whereby the remainder of said leads extend from said encasing structure.
Claim 3
Dependent Claim
30 words
A method of making an electrical element as set forth in claim 1 and including the step of initially disposing said conductor generally in one plane in said encasing structure.
Claim 4
Dependent Claim
45 words
A method of making an electrical element as set forth in claim 2 and including the step of disposing said conductor in a tortuous pattern between the lead attaching parts that provide the shortest electrical circuit through said conductor between said lead attaching ends thereof.
Claim 5
Dependent Claim
33 words
A method of making an electrical element as set forth in claim 3 and including the step of forming each lead attaching end in a tortuous pattern between adjacent lead attaching parts thereof.
Claim 6
Dependent Claim
39 words
A method of making an electrical element as set forth in claim 4 and including the step of forming the lead attaching parts of each lead end so that the same are disposed in aligned relation with each other.
Claim 7
Dependent Claim
43 words
A method of making an electrical element as set forth in claim 5 and including the step of forming the lead attaching parts of said lead ends so that the same are disposed in two rows disposed parallel and spaced from each other.
Claim 8
Dependent Claim
38 words
A method of making an electrical element as set forth in claim 6 and including the steps of dIsposing said leads between said rows, and securing outwardly turned ends of said leads to the desired lead attaching parts.
Claim 9
Dependent Claim
44 words
A method of making an electrical element as set forth in claim 1 and including the step of forming said encasing structure from a pair of flexible tape-like strips superimposed on each other and securing said part of said leads and said conductor therebetween.
Claim 10
Dependent Claim
20 words
A method of making an electrical element as set forth in claim 1 wherein said element comprises a temperature sensor.
Claim 11
Dependent Claim
21 words
A method of making an electrical element as set forth in claim 1 wherein said element comprises an electrical heating element.
