    THE role of modern military aircraft is inexorably reflected in its electric system. The aircraft electric system must maintain its continuity to complete its mission. Beyond that, the utmost of reliability and continuity is required of the electric power system supplying ¿safety of flight¿ items such as the Gyro horizon instrument, the turn and bank instrument, the fuel quantity instrument, the...

    SEVERAL years ago it became necessary to revise the primary distribution system in a large chemical plant. This plant was approximately 25 years old and had undergone a rapid expansion during this entire period. The type of electric distribution system which had developed is typical of many other large chemical plants which have expanded over comparable periods of time. The original plant electric...

    THERE are a number of methods for calculating the response of a linear system to an arbitrary input which divide the input into a series of units so small that each can be approximated quite crudely, but they are all quite laborious and require a very high degree of accuracy of computation to achieve adequate accuracy in the calculated response. Even more important, they give very little insight i... View full abstract»

    Undervoltage relays and starter solenoids respond to motor residual voltage. Test data are presented showing how such response can affect operation of an automatic transfer in a secondary selective system supplying induction motors. Suggestions are given for relay application. View full abstract»

    THE purpose of this paper is to extend the utility of certain synthesis techniques, which have proved useful in the design of continuous feedback systems, to the study of sampled-data systems. In recent publications,1,3,6 the z-transformation has been utilized to advantage in simplifying the analysis of sampled-data systems. However, several useful techniques applicable to the design of continuous... View full abstract»

    EVER-increasing street traffic congestion has directed renewed interest in rapid transit railroads as the most effective means for bringing large numbers of people swiftly across the broad expanse of modern urban areas. However, the staggering capital outlays required for this kind of facility demand that automation be applied to keep the price of service within range of the market. Fortunately, t...
