    Increasingly the position of the engineer, not only as a technically skilled producer but also as an element in a more effectively co-ordinated social system, becomes of major importance and interest. It is accordingly greatly to the benefit of our readers that we present an analysis of this segment of the life of the professional engineer ably prepared by a recent Director of the Institute, who i...

    In less than five years, loran, the American embodiment of a new method of navigation, has grown from a concept into a service used by tens of thousands of navigators over three tenths of the surface of the earth. Even under the stress of military urgency, the direct development cost of this system has been less than two per cent of the seventy-five million dollars so far spent for operational equ...

    Investigations of methods for control of precipitation static are discussed. Because of difficulties associated with careful studies of the performance of antistatic devices on aircraft flying in natural charging conditions, methods were devised that permitted natural conditions to be simulated in fair-weather flights and in a laboratory hangar constructed especially for this purpose. Studies show... View full abstract»

    The important high-voltage electrical characteristics of aircraft in flight are determined from (a) flight operations in precipitation areas; (b) flight operations using a new artificial charger to electrify the airplane in flight; (c) high-voltage experiments on the airplane supported in a giant hangar; and (d) theoretical analysis. It is shown how the fundamental electrical constants of the airp... View full abstract»

    A special artificial-lightning generator has been developed through the University of Minnesota co-operation with the Naval Research Laboratory, to provide accurate laboratory duplication of thunderstorm-cloud field conditions. Conditions of electrical-field stress before the lightning discharge are produced by an automatically controlled transition of a generator of high-voltage direct current in... View full abstract»

    A theoretical study is made to determine the effects of multipath propagation on over-all transmission characteristics in frequency-modulation radio circuits. The analysis covers a simplified case where the transmitted carrier is frequency-modulated by a single modulating frequency and is propagated over two paths having relative delay and amplitude differences. Equations are derived for the recei... View full abstract»

    Heretofore, it has been the general practice, both in the United States and abroad, to assemble the audio equipment components used for broadcasting and motion-picture sound studio operation in so-called relay racks or cabinets. These assemblies were generally supplemented with a control console, separate from the equipment racks, but connected thereto with a suitable multipair shielded cable. Whi... View full abstract»

    The need to render ceramic surfaces water-repellent in certain electrical applications under high humidities is discussed. Organosilicon compounds have been found to make ceramic surfaces water-repellent. The nature of a family of such compounds, the dimethylsilicones, is briefly described. Methods of preparing and treating glass surfaces with silicones are presented. Results of tests on treated a... View full abstract»

    A-new ionization gauge is described for measuring pressures from 10-4to less than 10-8millimeters of mercury. Except for a multiplying factor of 10, it gives a direct reading of residual air pressure. The gauge employs two plates, as the electron and ion collector, respectively. They are located on opposite sides of the filament, but equidistant from it. This allows easy outg... View full abstract»

    Satisfactory methods are described for measuring the resonant frequency, Q, and shunt resistance of resonant cavities. Some of the wavemeters and other equipment developed for these measurements are described. The methods of determining resonant frequencies permit moderate accuracy in absolute measurements and very high precision in the comparison of the resonant frequencies of two cavities. Three...
