    A microwave simulator for controlled variation of air-flow velocity in the dc to 500 kHz frequency range is described. The simulator serves for measurement of the transfer function of hot-wire and hot-film transducers used in turbulence research. The microwave simulator consists of an X-band power modulated klystron which delivers electromagnetic energy to the transducer, mounted in a small-size c... View full abstract»

    A Perkin-Elmer Model 112 infrared spectrometer has been modified for double-pass operation in the 400 to 173 cm-1 region. This region is scanned with two gratings, 40 lines/mm and 20 lines/mm, used in first or der at the Littrow mirror position. A 14° off-axis paraboloid mirror is employed, and filtering is accomplished with reststrahlen plates, scatter plates, and polyethylene transmission filte... View full abstract»

    This paper describes an improved infrared scanning microscope. It was designed for use as an analytical tool where temperature or small thermal gradients might be an indication of device failure or potential failure. This method would be particularly applicable, for instance, to dynamic testing of integrated circuits where conventional techniques are generally unsuitable. Initial tests indicate th...

  • Thle monopole-a new instrument for measuring partial pressures

    Publication Year: 1966, Page(s):94 - 98
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1189 KB)

    Design parameters appropriate to the construction of a monopole type mass spectrometer suitable for use as an ultra-high vacuum partial pressure analyzer are developed and elaborated. Performance results of an instrument built to these parameters are presented. Results indicate a usable mass range of 300 amu, with unit resolution over the whole range. Ultimate sensitivity is in the 10-14 View full abstract»

    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2953 KB)

    A simple, accurate microwave test set has been devised for measuring coaxial or waveguide insertion loss. The instrument is designed primarily for highest precision with low attenuations. It is composed almost entirely of commercially available equipment and components, is portable, and can be operated in the laboratory or in the field from ac mains or batteries. The precision of the measurements ... View full abstract»

  • Solion tetrode-a reliable integrator and memory device

    Publication Year: 1966, Page(s):105 - 109
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (934 KB)

    The solion tetrode is an electrochemical cell whose output current is proportional to the integral of the input current. The principle of operation is based on the controlled flow of ions, specifically iodine, through the electrolyte. If a current is introduced into the input of the solion, the unit continuously reads out electrically the integral of the input current. When the input current is re... View full abstract»

  • Method for the Measurement of "Q"

    Publication Year: 1966, Page(s):109 - 112
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (573 KB)

    The quality of ferrite materials has improved markedly over the last few years. Inductor "Q's" of 500 to 700 at frequencies of 100 to 200 kilocycles appear quite frequently in filter designs. Techniques of measurement of the storage factor Q, however, have not kept pace. The residual phase angle in bridges and the series and parallel damping in Q meters cause considerable error. For this reason th... View full abstract»

    A magnetometer utilizing a superconducting quantum interference device (SQUID) as a magnetic flux sensor is described. Its unique capabilities include: sensitivity of about an order of magnitude better than that of heretofore published magnetometers of other types, measurement range extending to zero field, and appreciable frequency response at high sensitivity (12 c/s bandwidth at 10.7 μG...

  • A Self-Balancing Bridge with Range and Precision Adequate for a Platinum Thermometer

    Cited by:  Papers (5)

    Calorimetry at NBS needs automation of bridge readout and bridge balancing. Bridge-balancing logic allows it to track the thermometer with progressively decreasing deviations as thermometer temperature approaches equilibrium. A step in the next decade does not interrupt since carry is automatic. Thermometer lead resistance is compensated as lead unbalance changes. Readout, at appropriate times, is... View full abstract»

  • FM Receiver Measures Field Intensity

    Publication Year: 1966, Page(s):132 - 133
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1324 KB)

    One of the limiting factors in measuring field intensity at the fringe area of an antenna is that the white noise level may be equal to or greater than the carrier signal. In addition, this noise level may vary with time of day, thereby rendering calibration for ambient-noise level an uncertain procedure. This paper describes a field-intensity measuring technique that overcomes this limitation. Th... View full abstract»
