    An equivalent circuit is described for the three-winding transformer which is similar in form to the classical equivalent T of the two-winding transformer. As in the equivalent T, the performance of the circuit shown can be visualized and the elements of the circuit can usually be related to specific transformer constants. It is shown that the circuit is also exact. View full abstract»

    In the VHF range, high-quality narrow-band filters with reasonable physical dimensions are extremely difficult to realize. Excessive pass-band insertion loss accompanies filters employing lumped constant elements, and unreasonable size is a natural consequence of coaxial-resonator filters. Harmonic crystal filters are inadequate because of the unpredictable amount of spurious modes above the harmo... View full abstract»

    The dissipation in a silicon rectifier depends on the characteristics of the rectifier (threshold voltage and ohmic resistance) and the circuit constants (inductive, resistive, or capacitive load). Dissipations under these different conditions are calculated. The maximum permissible dissipation is limited by maximum junction temperature and thermal stability. The stability criterion depends on the... View full abstract»

    An approach to the high-frequency representation is developed from the point of view of distributed-parameter networks. This viewpoint may be directly employed to compute insertion or transmission functions. Alternatively, it provides a method for determining the element values for lumped-parameter equivalent circuits. This method is most easily applied to transformers having two winding layers wi...

    Motion of unipolar ions in insulating liquids creates strong coupling between electrical and hydrodynamic systems energy. This permits us to pump liquids directly with electrical power or to build up electrical energy from liquid motion. The phenomenon has been used to build high-impedance electrohydrodynamic components such as switches, relays, voltage regulators, voltage generators and dc transf... View full abstract»

    Polycarbonates have interesting possibilities as materials for capacitor films. In mechanical and electrical properties, polycarbonates fall generally between polystyrene and Mylar, and possess an unusually low temperature coefficient of dielectric constant. They can be cast from solvent and can be metallized; hence, they are adaptable to lacquer film techniques. This paper reports a preliminary e... View full abstract»

    This paper describes a high-gain phase-sensitive magnetic amplifier which simultaneously possesses the high-gain property of the self-saturating (100 percent positive feedback) amplifiers and the limited circulating current property of the low-gain zero feedback amplifiers. These features are obtained by using feedback windings to obtain the self-saturating large-gain property. However, the feedba... View full abstract»

    An analysis has been made and a design procedure established for fuses other than those using round wire and with, or without, a restricted cross section for part of the fuse length. Fuses of restricted section are, however, the major interest since they may be used to give different current/time characteristics by varying their dimensions. These different characteristics may be predicted accurate... View full abstract»
