    During the past few years many railroad companies have conducted extensive tests of inductive and radio carrier communication systems. Excerpts from reports of these tests point out that these systems though not perfect are already rendering useful service. View full abstract»

    Originally presented as an address before the recent National Electronics Conference in Chicago, this article considers one viewpoint in the current controversy over the question of government support of scientific research. The author takes his stand on the side of federal promotion of science, provided the policy to be pursued is both scientifically and politically acceptable. Undoubtedly, some ... View full abstract»

    Slow-acting relays have been the unobtrusive little behind-the-scenes timing-control elements in various kinds of electrical installations for so long that they now are taken for granted. Although supervisory control, telemetering, and protective relay systems for electric power systems, have been covered extensively in technical literature, the role played by the slow-acting relay for the most pa...

    ATYPICAL RELAY, used by the millions in telephone offices, in shown in Figure 1 — the U-type relay. This particular type is not a slow relay; its action time is about 1/20th second or less. It can be slowed, however, to give times in the range from 50 to 500 milliseconds, which is the ordinary range of delay in telephone relays. These delays can be obtained — at reasonable cost, with...

    THE TIME INTERVAL required for the closing or opening of a relay contact after the current is applied or removed, is dependent upon the balance of mechanical forces acting on the mass of the armature. These balanced forces are the spring load force, the magnetic operating force, the frictional force, and the force of acceleration. Because changes in the magnetic forces occur when the armature is u... View full abstract»

    THE APPLICATION of telephone relays in the power field is not new. These relays have been in use for years by many utility companies on special applications. The larger power manufacturers have used them as elemental units in telemetering, selective calling on carrier telephone circuits, carrier relay protection, protective distance relaying, and also in supervisory control.

    This searching consideration of the question of organizing or reorganizing the engineering profession is presented for the purpose of stimulating additional thought and discussion by the entire AIEE membership. The author, speaking in the light of experience as president of the Texas Society of Professional Engineers and vice-chairman of the AIEE membership committee, supports Plan B of the variou...
