Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
IN THE FABRICATION OF ENCAPSULATED ELECTRICAL CAPACITORS, THE STEPS OF: TRANSVERSELY POSITIONING UNENCAPSULATED CAPACITOR SECTIONS IN SPACED RELATION INTERMEDIATE TWO PARALLEL LENGTHS OF WIRE WITH THEIR ELECTRODE ELEMENTS SELECTIVELY CONNECTED THERETO TO FORM A LADDER-LIKE SERIES THEREOF, POSITIONING THE LEAD CAPACITOR SECTION IN SAID SERIES RELATIVE TO THE WALLS OF A MOLD BY INTERPOSITION OF A LONGGITUDINALLY SLOTTED SLEEVE OF INSULATING MATERIAL INTERMEDIATE SAID SECTION AND THE MOLD WALLS OF A THICKNESS AT LEAST EQUAL TO THE MINIMAL DESIRED DEPTH OF ENCAPSULATION AND INTRODUCING COMPATIBLE LIQUID ENCASING MATERIAL INTO SAID MOLD TO FILL ALL VOIDS THEREWITH AND TO MERGE, UPON SOLIDIFICATION THEREOF, WITH SAID SLOTTED SLEEVE TO FORM A UNITARY ENCLOSED CASING FOR SAID CAPACITOR.
