Claim 1
Independent Claim

A METHOD FOR ADJUSTING THE RESISTANCE OF A PALLADIUM GLAZE RESISTOR COMPRISING MAKING SAID RESISTOR AN ELECTRODE IN AN ELECTROYLSIS CELL HAVING AN INERT SECOND ELECTODE OF OPPOSITE POLARITY, SAID CELL HAVING A SUITABLE ELECTROLYTE BETWEEN SAID ELECTRODES, AND PASSING A DIRECT ELECTRIC CURRENT THROUGH SAID CELL, THEREBY INCREASING THE RESISTANCE OF SAID RESISTOR WHEN SAID RESISTOR IS MADE ANODIC TO SAID INERT ELECTRODE, ND DECREASING THE RESISTANCE OF SAID RESISTOR WHEN SAID RESISTOR IS MADE CATHODIC TO SAID INERT ELECTRODE.
