    More than a dozen schemes for sending visual images by electricity appeared from 1877 to 1884. Some used multiwire lines and mosaic arrays; others used single lines and a scanning method-autographic, spiral, linear. Selenium cells and incandescent filaments were common elements. Basic ideas on scanning speed, repetition frequency, synchronism, picture elements, and beam modulation evolved during t... View full abstract»

  • Outlook for binary power plants using liquid-metal MHD

    Publication Year: 1970, Page(s):35 - 44
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (6387 KB)

    Preliminary testing and extrapolations thereof indicate that liquid-metal MHD can be used as a topping cycle to increase the efficiency of large central-station power plants. Because maximum temperatures as low as 870° C are effective, such binary plants are possible with existing material technology. The best present choices appear to be a potassium working fluid and either a (helium-or sodium-co... View full abstract»

    The lack of understanding, analyzing, and communicating technological ``uncertainties'' are presented by the author as seriously undermining the effectiveness of decision-making in both public affairs and industry. Uncertainties are as important to truth as certainties and should be part of all forms of technical communication. ``Technical truth,'' it is pointed out, is not developed in the legal ...

  • Technological advances in large-scale integration

    Not very long ago the concept of large-scale integration was just that-a concept. But since that time most of the more difficult technological problems have been resolved and many others are well on their way to solution. The important potential advantages of LSI-reduced cost, improved reliability, size and weight reductions, and computerized fabrication-served to provide the impetus for their rap...

  • Toward high stability in active filters

    Publication Year: 1970, Page(s):63 - 66

    About four years ago, the consensus among network theorists was that active synthesis was headed nowhere because of high sensitivities. At that time, active filters had a well-deserved reputation among design engineers for poor stability. Practical active filters were plagued with self-oscillations, nonadjustability, nonreproducibility, and high thermal coefficients. Active network theory could ac... View full abstract»

    Although solid fuels still remain a dominant energy source for generating electricity throughout the world (taken as a whole), the overall fuel-energy supply picture has changed dramatically in the last 45 years. In 1925, coal was the overwhelming source of caloric content; today it ranks second to oil. Four decades ago-and until World War II-the United States was a significant net exporter of ene...

    This article describes a novel, large-scale instructional television system now in operation at Stanford University, under the auspices of the School of Engineering. The network brings the campus classroom and instructor to graduate students employed by participating organizations at inconvenient distances from the school, and talk-back capability is included to provide a live classroom situation....
