Abstract
Abstract A high vacuum chamber surrounds each exposed end of a segmented aluminum conductive paper insulated cable for preventing the oil from the impregnated cable insulation from migrating to the end of the conductor after the aluminum conductor is cleaned with solvents to permit heliarc welding or buttering of the end of the conductor prior to splicing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
93 words
A method of buttering the end of a stranded cable that has been stripped of insulation which method includes the steps of, first cleaning said end with a small amount of solvent, then evacuating the region around a portion of the stripped end of the cable between the end of the insulation and the cable end along a length of the cable that is greater than the cable diameter while applying heat to butter the end while preventing contamination from migrating to the end being buttered to keep said end free of contaminant.
Claim 2
Independent Claim
93 words

Claim 3
Dependent Claim
33 words
