    Machine-controlled presentation subsystems have been developed for the purpose of displaying information at electronic speeds. These systems transform the continuous flow of facts and data received by an organization into selected, significant information, which is then presented in capsule form to the decision maker for implementation.

  • An electrical essay: The radiant heat pump

    An idealized form of the radiant heat pump (RHP) is shown in Fig. 1 (a). The box has square ends, it is long and somewhat tapered, and is completely lined with perfectly reflecting surfaces. There is a plate suspended at each end. Each plate almost fills its end, and almost touches. The plates have a black-body coating. At roughly room temperature, 27 C, the radiant emission from each square inch, all in the infrared, would be 0.3 watt. Let both plates be brought to the 27 C temperature when first placed in the box.

  • Steady-state and transient ratings of electric wire

    Publication Year: 1961 , Page(s): 125

    The Need for an accurate, reliable method of determining wire ratings has been apparent for some time. Present current ratings have been in use for many years and are unduly conservative because of the large safety factors included. The idea of the large safety factors undoubtedly came from the desire to allow for all possible uses of the wire. This does not make any allowances for different environments or service for the wire. With the increasing importance of weight and cost considerations, an accurate, reliable, and easily used method of determining wire ratings has become a necessity. View full abstract»

    The sharp increase of population in the San Francisco Bay area in California has expanded industry and greatly increased home ownership. The resultant demand for telephone circuits has created a cable and conduit problem which The Pacific Telephone and Telegraph Company is attempting to solve by means of an experiment that intensifies the utilization of the existing cable plant.

    The Joint Subcommittee on Development and Research, Edison Electric Institute and Bell System, has issued a 1960 weighting characteristic for telephone influence factor (TIF). This factor is dimensionless and provides an index of the inductive influence of a power system wave shape. Fig. 1 shows the new curve in comparison with its several predecessors.

    This is a fault-sensing and switching system serving as an automatic guardian of the quality of a broadband (1,300 kc) transmission channel. Acting upon a loss in transmission level or an increase in noise, it transfers a communication traffic load from a failing regular channel to a normally unassigned standby channel. Protection afforded by standby channel can be shared by three regular channels. View full abstract»

    Ethical responsibilities in the recruiting of engineering college graduates, both on the part of the prospective employer, as well as the engineering graduate, have been a matter of interest and action on the part of the American Society for Engineering Education (ASEE) for many years. Proposed recruiting codes have been produced and reviewed with other interested placement associations, business groups and engineering societies, including AIEE and the Engineering Council for Professional Development (ECPD).
