Abstract :
Recent progress in various phases of electrical insulation research was reflected in the 26 progress reports informally presented at the 12th annual meeting of the Conference on Electrical Insulation of National Research Council, held November 2–4, 1939, at Cambridge, Mass., and reported briefly in the December issue, page 526. One of the four sessions was devoted to chemistry and physics; one to measurements; and two to materials. As was true of last year´s sessions, the emphasis was on research in the fundamentals of electrical insulation rather than on applications to practice, although the Conference continued in its unique position of effectively bringing together the active representatives of both the scientific and the “practical” groups interested in the general subject. Brief abstracts reflecting the high lights of the various reports presented are given on this and the following three pages, all based upon abstracts prepared by the respective authors.
