Semi-conducting coating for use in a self-healing alternating voltage capacitor and method

Claim 1

IN A SELF-HEALING ALTERNATING VOLTAGE CAPACITOR, A SHEET MEMBER OF DIELECTRIC MATERIAL HAVING A DETERMINED THICKNESS AND A DETERMINED SURFACE AREA; A FIRST METAL LAYER ON A FACE OF SAID SHEET MEMBER COVERING A FIRST PORTION OF THE SURFACE AREA OF SAID SHEET MEMBER AND HAVING AN EDGE FORMING A BOUNDARY BETWEEN THE FIRST PORTION OF SAID SURFACE AREA AND A SECOND PORTION OF SAID SURFACE AREA FREE OF SAID FIRST METAL LAYER; AND A SECOND LAYER OF SEMI-CONDUCTOR MATERIAL ON A PART OF SAID SECOND PORTION OF THE SURFACE AREA OF SAID SHEET MEMBER NEXT ADJACENT THE EDGE OF SAID FIRST METAL LAYER, SAID LAYER OF SEMI-CONDUCTING MATERIAL HAVING A DETERMINED WIDTH AND A SPECIFIC RESISTANCE PER SQUARE UNIT R= K(D/EO.ER.BS(2).W) WHEREIN K IS A CONSTANT HAVING A MAGNITUDE IN THE RANGE 10**-2 TO 10**0, D IS THE THICKNESS OF SAID SHEET MEMBER IN MM., EO IS THE DIELECTRIC CONSTANT FOR AIR, ER IS THE RELATIVE DIELECTRIC CONSTAND OF SAID DIELECTRIC MATERIAL, BS IS THE WIDTH OF THE LAYER OF SEMI-CONDUCTOR MATERIAL IN MM. AND W IS 2$ TIMES THE FREQUENCY OF THE ALTERNATING VOLTAGE AT WHICH SAID CAPACITOR OPERATES IN CYCLES PER SECOND.
