    As quadruplex video tape's 20-year dominance of TV recording ends, compact helical formats deliver greater production flexibility. The three most accepted formats are dealt with: two-inch transverse, one-inch helical, and one-inch segmented helical. It is examined how these new formats affect the television broadcast industry.

  • Satellite/energy: The Franklin Institute has high hopes for its big balloon: A mile-long hot-air balloon is proposed for space research and solar power generation

    Publication Year: 1978 , Page(s): 41 - 47
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (4325 KB)  

    A mile-long hot-air balloon is proposed for space research and solar power generation. The concept is one of a large, manned station-a free-floating, navigable craft-able to ascend to the stratosphere and to remain there for years. Buoyancy would be provided by solar-heated, confined air. The craft would be capable of performing very-long-term monitoring of chemical, physical, electrical, and biol... View full abstract»

    A technique that integrates economic, environmental, and site-specific data is based on the development of analytical tools. A prototype set of tools has been designed that allow analysis of environmental impact and cost/impact tradeoffs without requiring data on actual sites. Hierarchy of environmental and siting tools for power plant siting decisions includes computer models for generation expan... View full abstract»

    This eight-page technical paper describes new, easy-to-use methods for accurately measuring reflected signals over the 5-MHz to 18-GHz range. The techniques discussed yield accuracies in measuring standing-wave ratios that were previously unobtainable, even with computer-aided systems. View full abstract»
