    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4049 KB)  

    The first of a series of articles prepared by the newly formed AIEE nucleonics committee, this discussion gives a general introduction to the rapidly developing field of atomic research. The series will be a primer in nuclear theory for engineers, and will include such timely subjects as nuclear engineering, production of high energy particles, isotope separation, nuclear piles, and health hazards.

    Still another idea is added to the growing list of suggestions for improving the engineering curriculum. The authors, both teachers of English, suggest setting up a special graduate training program for potential teachers of English in engineering schools. Such a program would produce the ideal instructor — a teacher who is trained both in engineering and in English. View full abstract»

    THE Colorado River is a muddy stream that constitutes the lifeblood of the Pacific Southwest, the most important feature of which is the ultimate scarcity of its water or its ultimate inability to supply the potential needs of the communities dependent on it for irrigation and domestic water supply. The next feature of importance is the potential power capability of the river and its relation to the power needs of this same Pacific Southwest area. View full abstract»

    A governing system is proposed which is believed capable of accomplishing optimum and inherent load division among generating stations without dependence upon load telemetering systems. The primary objective of this article is the invitation of discussion which can guide further development of such a system. View full abstract»

    A 5-member commission of which the author was a member was sponsored by the Secretary of War to prepare a study on the Japanese electric power system. After 4 1/2 months in Japan, the commission made recommendations to General of the Army Douglas MacArthur with respect to reparations. This article stems from the author's experiences in examining the Japanese utility systems. View full abstract»

  • Electric drive for aircraft

    Page(s): 1206 - 1208
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (709 KB)  

    AERODYNAMIC EFFICIENCY of very large highs-peed propeller-driven aircraft could be increased substantially if the power plants could be moved out of the wings, thereby decreasing the size of the nacelles. In addition, a plan then might be worked out whereby each power plant could operate at its lowest specific fuel consumption point, with some units being shut down during low load periods. However, such a scheme is not feasible under current practice because of difficulties which would be encountered in transmitting mechanical power through flexible members. Stopping engines and feathering the propellers directly connected to them is a rather unsatisfactory method of reducing power, and can be quite dangerous in wartime. View full abstract»

    This brief history of studies in solar radiation well may serve to re-emphasize the significance of both ancient and recent discoveries. The romance of these studies, however, should not overshadow the long hours of labor contributed to each investigation. View full abstract»

    The importance of studying the properties of surfaces and other geometrical bodies of higher dimension as a whole instead of studying their properties in a small region was stressed by C. B. Allendoerfer, Haverford College, in a paper, “Global Theorems in Riemannian Geometry,” presented before the American Mathematical Society. View full abstract»

    An apparatus which is sufficiently flexible to be readily adaptable for use with rotating machinery of various sizes and designs is claimed to permit safe and rapid removal of heavy rotor assemblies. Cribbing, rollers, large capacity hoists are replaced by equipment which is safe to operate, and which allows for a minimum chance of accident. View full abstract»

    A new instrument for accurately measuring, recording, and controlling the rate of flow, as well as the total flow, of fluids applies an electrocaloric principle. A wattmeter is used to indicate and record the rate of flow and a watt-hour meter to register the total flow. The scale of the meter is linear and covers a very wide range. View full abstract»
