Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
IN A CAPACITOR ASSEMBLY HAVING A PLURALITY OF CONVOLUTELY WOUND LAYERS OF THERMOPLASTIC DIELECTRIC MATERIAL AND A COATING OF ELECTRODE MATERIAL DEPOSITTED ON ONE SURFACE OF EACH OF SAID LAYERS SO THAT FIRST PORTIONS OF THE ELECTRODE COATED THERMOPLASTIC IN SUCCESSIVE LAYERS ARE IN OVERLAPPING ARRANGEMENT AND SECOND PORTIONS OF THE ELECTRODE COATED THERMOPLASTIC IN ONE LAYER ARE IN NON-OVERLAPPING ARRANGEMENT RELATIVE TO SECOND PORTIONS IN THE OTHER LAYER, SAID SECOND PORTIONS FORMING THE END SURFACES OF SAID ASSEMBLY, THE IMPROVEMENT COMPRISING: ELECTRICAL LEAD MEANS POSITIONED TRANSVERSE TO THE CAPACITOR WINDING AXIS AND PARTIALLY EMBEDDED IN SAID SPACED END SURFACES; AND A COATING OF ELECTRICALLY CONDUCTIVE MATERIAL OVERLYING AND CONTACTING AT LEAST AN ENEMBEDDED PORTION OF SAID ELECTRICAL LEAD MEANS AND AT LEAST A PORTION OF SAID SECOND PORTIONS OF ELECTRODE COATED THEREMOPLASTIC FORMING SAID SPACED END SURFACES.
Claim 2
Dependent Claim
