    IT is fitting that in Philadelphia we should celebrate the centenary of the great, discoveries in electromagnetism. It was here that Franklin's investigations in electricity were made, culminating in the kite experiment. It was here that he and a few confreres founded the American Philosophical Society which became a national institution for the spread of that spirit of science and philosophy char...

    THE names of Oersted and Ampère always recall to my mind the names of several other great men of science who with Oersted and Ampère form a group of intellectual giants. Their pioneer discoveries produced the science of physics and engineering of today. The names of the members of this immortal group are: Copernicus, Kepler, Galileo, Newton, Oersted, Ampère, Faraday and Maxwel... View full abstract»

    IT is eminently fitting that the Pacific Coast members of the Institute, in convention assembled, should pause in their labors on present day problems and consider the significance of this day and year as the hundredth anniversary of the fundamental discoveries of Oersted, Arago, and Ampère. One hundred years ago today, the 21st of July, 1820, Oersted announced his notable discovery of the ... View full abstract»

    The Greaves-Etchells system suses the delta-Y connection, which is admittedly the best combination for producing evenly loaded phases. The transformers are connected delta on the primary side and Y on the secondary. One of the legs of the transformer is applied directly to the bottom of the furnace by means of copper busbars and a copper plate, which conducts the current through a bottom composed ...

    In considering the steps in the advancement of a new process of manufacture the fundamental reason for the introduction of the new process is sometimes lost sight of. A discussion of the electric furnace for the manufacture of high-grade steel immediately raises the question as to why the older steel making processes are now being replaced. View full abstract»

    THIS article records an interesting war development of small machines of very special design carried out by the writer in 1917 for the Signal Corps and for the Bureau of Steam Navigation. The company with which the writer is associated, as its share in war work was almost entirely engaged in the manufacture of motor generators, etc., for wireless service for the Government.

    13. The maximum power which an antenna can abstract from sustained waves and deliver to a detector. To make the delivery of power from sustained waves to the detector associated with a given antenna a maximum, the equivalent resistance of the detector, Rd, should be made equal to the sum of the radiation resistance, Rr, plus the wasteful resistance Rw, of the anten...
