Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
100 words
A PROCESS OF RENDERING A POLYMERIC WIRE COATING SUITABLE FOR ADHESION WHICH COMPRISES CONTINUOUSLY PASSING A POLYMERIC COATED WIRE THROUGH A PLURALITY OF ELECTRODES, AND CONTINUOUSLY SUPPLYING SAID ELECTRODES WITH AN ALTERNATING CURRENT AT A FREQUENCY OF FROM 1 TO 50 KC. PER SECOND AT A VOLTAGE WHICH IS MAINTAINED BETWEEN THAT VOLTAGE WHICH CAUSES ELECTRICAL DISCHARGE IN THE ATMOSPHERE SURROUNDING SAID POLYMERIC COATING AND THAT VOLTAGE WHICH CAUSES BREAKDOWN OF SAID POLYMERIC COATING, WHILE MAINTAINING A PHASE DIFFERENCE OF 180* BETWEEN SAID ELECTRODES AND WHILE MAINTAINING SAID WIRE AT A POTENTIAL APPROXIMATELY MIDWAY BETWEEN THE POTENTIALS OF SAID ELECTRODES.
