    Application of a recently developed method whereby it is possible virtually to see the voids in the layer structure of high voltage cable insulation shows most such insulation to be mechanically irregular. Lack of mechanical uniformity in the cable as manufactured is responsible for much of the ionization after the load cycle, and probably to a great extent for ionization breakdown. Application of the method and of supplementary methods should lead to better load cycle stability, improved installation practice, and ultimately to reduced insulation thicknesses.

    The paper reviews the historical development of joint use and the general results to date of studies of protective problems of lower and higher voltage joint use. The safety features are reviewed from the standpoint of (1) subscribers' premises, (2) employees, and (3) telephone plant. Characteristics of equipment of power and telephone plant as far as they relate to this problem are given. The various factors which determine magnitude and duration of the current and voltage in the telephone plant resulting from a contact with power conductors are discussed. Improved methods for obtaining safety under various conditions, where higher voltage joint use is found to be the best over-all solution, are described. View full abstract»

    The present method of rating resistance-welding transformers varies with the different manufacturers, causing a certain amount of confusion among the users of this equipment. It is recommended that a standard method of rating, based on the thermally equivalent continuous output, be adopted and adhered to by the manufacturers. The general requirements of a welding transformer are discussed for the purpose of explaining the desirability of such a standard rating. Certain of the recommendations made herein are already embodied in the present AIEE Standards for resistance welding apparatus, and in the standards adopted by the Resistance Welder Manufacturers Association, but it is further recommended that these standards be altered to require additional name plate data. It is hoped that the transformer manufacturers and users will recognize the desirability of such standardization, and co-operate in its universal adoption. View full abstract»
