    The further development of an aural receiver for the piloting cable system of guiding ships into harbors is described. In particular, the choice of a detecting coil of the most desirable number of turns, the proper choice of transformer input impedance and step-up ratio, and the use of audio frequency tuning of the coil circuit are discussed. The design of the latest coil, receiver, and amplifier ... View full abstract»

    The authors describe a new type of cold electrode power rectifier tube utilizing gaseous conduction, and based on the following principles: No considerable gaseous conduction occurs between coaxial cylindrical electrodes separated by less than the mean free path of the electrons. An axial magnetic field (perpendicular to the electric force) will cause the electrons to pursue a longer path, and thu... View full abstract»

    The transmission system of "frequency modulation" (transmission by variation of the frequency of the radiated wave) is mathematically analyzed, and the width of the band of frequencies occupied by this method of transmission at a given speed is compared with the width of the corresponding band for transmission by amplitude variation. It is proved that the frequency modulation system using a spacin... View full abstract»
