Abstract
Abstract 1,110,058. Connecting-pieces for anodes. UNION CARBIDE CORPORATION. 5 May, 1965 [2 June, 1964], No. 18880/65. Heading H2E. A cable 10 to be connected to a graphite anode 22 is brazed to a copper, silver or copperplated steel spike 16 which is then forced with an interference fit into the end of a channel drilled in the anode. A polyethylene sleeve 26, placed over the cable insulation, is fitted into the open end of the channel and polyethylene is then forced through a communicating channel 32 into the space surrounding the stripped end of the cable so as to form a seal.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
180 words
AN IMPROVED ANODE-CABLE CONNECTION COMPRISING, IN COMBINATION, AN ANODE HAVING TWO CHANNELS, THE FIRST OF SAID CHANNELS HAVING TWO SECTIONS OF DIFFERENT CROSS-SECTIONAL AREAS, THE FIRST OF SAID SECTIONS EXTENDING FROM THE INITIAL OPENING OF SAID FIRST CHANNEL TO A DEPTH WITHIN SAID ANODE AT SOME PREDETERMINED DISTANCE FROM SAID INITIAL OPENING, AND THE SECOND OF SAID SECTIONS BEING OF REDUCED CROSS-SECTIONAL AREA AND IN COMMUNICATION WITH SAID FIRST SECTION AND TERMINATING IN SAID ANODE AT A PREDETERMINED LENGTH FROM THE POINT OF COMMUNICATION WITH SAID FIRST SECTION, AND THE SECOND OF SAID CHANNELS IN COMMUNICATION WITH SAID FIRST SECTION OF SAID FIRST CHANNEL; A CABLE, A PORTION OF WHICH EXTENDS ALONG SAID FIRST SECTION OF SAID FIRST CHANNEL; AN ELECTRICALLY CONDUCTIVE METAL SPIKE TO WHICH SAID CABLE IS SECURED AND WHICH EXTENDS INTO SAID SECOND SECTION OF SAID FIRST CHANNEL AND IS IN AN INTERFERENCE FIT RELATIONSHIP WITH SAID ANODE; AND A POLYETHYLENE SEALANT WHICH FILLS ALL THE AVAILABLE SPACE IN SAID CHANNELS AND COMPLETELY SURROUNDS SAID CABLE AND SAID ELECTRICALY CONDUCTIVE METAL SPIKE AT THEIR POINT OF CONNECTION.
