Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A DEVICE FOR CONDUCTING ELECTRICITY UNDER CONDITIONS OF HIGH PRESSURE AND TEMPERATURE AND COMPRISING A METALLIC SHEATH, A CONDUCTOR EXTENDING LONGITUDINALLY THROUGH SAID SHEATH, A THIN, RESILIENT SEALING MEMBRANE GENERALLY TRANSVERSELY POSITIONED AT AN INTERMEDIATE POINT IN SAID SHEATH AND HAVING AN APERTURE FOR RECEIVING SAID CONDUCTOR, SAID MEMBRANE HAVING PORTIONS LAPPED UP AND IN CONTACT WITH SAID METALLIC SHEATH AND SAID CONDUCTOR, AND REFRACTROY INSULATING POWDER FILLING THE REMAINDER OF SAID SHEATH ON BOTH SIDES OF SAID MEMBRANE AND BEING IN INTIMATE CONTACT WITH SAID MEMBRANE, SAID POWDER BEIN HELD IN A HIGHLY COMPACTED STATE BY SAID SHEATH SO AS TO PLACE SAID MEMBRANE IN COMPRESSION AND BRING IT INTO SEALING ENGAGEMENT WITH SAID CONDUCTOR, SAID SHEATH, AND SAID POWDER TO PREVENT GAS LEAKAGE IN A LONGITUDINAL DIRECTION WITHIN SAID SHEATH UNDER THE APPLIED PRESSURE.
