ABSTRACT:
A process for impregnating carbon resistors used in the telephony art to reduce or eliminate dusting of carbon particles during arcing, thereby permitting gap distances to be accurately maintained, and the useful life of the electrodes to be extended. The process includes the immersion of completed electrodes into a water solution of polyethylene glycol, whereby the solution is absorbed between the carbon granules, following which the water vehicle is allowed to evaporate, leaving a thin coating of glycol which binds the carbon granules together without significantly altering the resistive qualities of the carbon.
