  • Cold trap performance : a general analysis

    Creator:
    Rothwell, Micheal Olin
    Abstract:
    A cold trap is a device used to remove certain impurities from a liquid metal by controlled precipitation of such impurities. An investigation of the thermal characteristics of laminar flow in two air-cooled cold traps was made. This investigation showed that the sodium heat transfer rate is a function of...

  • Polycarbonate as a photoplastic stress freezing material

    Creator:
    Broderick, John Justin
    Abstract:
    Dead weight creep tests were conducted on polycarbonate in order to determine if it is a linear viscoelastic material; or if it is not, then to determine the feasibility of photoplastic stress freezing. Secondary objectives were: the determination of the parameters in the creep compliance of a four element viscoelastic...

  • A photoelastic stress analysis of a beam under shear and compressive loads

    Creator:
    Bitting, Kenneth Robert
    Abstract:
    The determination of failure is complicated when a structural element is subjected to combined rather than simple stresses. This is especially true when the principle of superposition does not apply. For such cases, tests of the element under the expected loads are required to determine its failure criteria. In this...

  • A numerical analysis of ice fog produced by automobiles

    Creator:
    Nelson, William George
    Abstract:
    A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

  • Airborne sampling of particles emitted to the atmosphere from Kraft paper mill processes and their characterization by electron microscopy

    Creator:
    Augustine, Frank Edward
    Abstract:
    A high volume sampling system, employing Nuclepore filters and designed for sampling particulate in the plumes from industrial sources using a light aircraft, is described. The effluent of kraft paper mills was sampled using this system and then analyzed by electron microscopy. Size distributions of particles were obtained at several...

  • Design, construction and testing of torsiograph

    Creator:
    Hamann, David Eugene
    Abstract:
    The crankshaft of an internal combustion engine experiences torsional vibrations which become critical at certain running speeds and can cause overstressing in the crankshaft, leading to failure in some cases. The object of this study was to design, construct and test an instrument to measure these oscillations at one point...

  • Design considerations for strain gage transducers

    Creator:
    Smith, Harlan Bradford
    Abstract:
    Design considerations are presented which apply to all types of electrical resistance strain gage transducers. While the concepts apply to mass produced transducers, the information should be most useful for the engineer or technician who designs one-of-a-kind or "home-made" transducers. Errors which affect the accuracy of strain gage transducers are...
