    [Auszug] From an electrical point of view the homopolar generator is a large capacitor. When it is connected across a fixed resistance the output current rises rapidly to a peak and then decays exponentially. This is a disadvantage when the generator is used to power devices such as high field magnets which ...

    [Auszug] The homopolar generator was designed to produce a roughly sinusoidal current pulse lasting for nearly 2 sec with a peak of 1-6 million amp. In the initial tests1, this current was drawn from the rotors by means of sheet jets of sodium-potassium alloy. The brushes have been designed for the same ...

    [Auszug] THIS laboratory has been engaged for some time in the design and construction of a large homo-polar generator1. The generator was intended to provide a pulse of current, of roughly sinusoidal shape, into the orbital magnetic field coils of an iron-less proton-synchrotron for 10 GeV., the peak ...

    Notes:
    Abstract Day-time Pc 3–4 (≃5–60 mHz) and night-time Pi 2 (≃5–20 mHz) ULF waves propagating down through the ionosphere can cause oscillations in the Doppler shift of HF radio transmissions that are correlated with the magnetic pulsations recorded on the ground. In order to examine properties of these correlated signals, we conducted a joint HF Doppler/magnetometer experiment for two six-month intervals at a location near L = 1.8. The magnetic pulsations were best correlated with ionospheric oscillations from near the F region peak. The Doppler oscillations were in phase at two different altitudes, and their amplitude increased in proportion to the radio sounding frequency. The same results were obtained for the O- and X-mode radio signals. A surprising finding was a constant phase difference between the pulsations in the ionosphere and on the ground for all frequencies below the local field line resonance frequency, independent of season or local time. These observations have been compared with theoretical predictions of the amplitude and phase of ionospheric Doppler oscillations driven by downgoing Alfvén mode waves. Our results agree with these predictions at or very near the field line resonance frequency but not at other frequencies. We conclude that the majority of the observations, which are for pulsations below the resonant frequency, are associated with downgoing fast mode waves, and models of the wave-ionosphere interaction need to be modified accordingly.

    Notes:
    Abstract A Monte-Carlo approach for solving huge, dense matrices for eigenvalues and eigenvectors is proposed. The matrix must satisfy certain conditions including a smooth density of diagonal elements curve and relatively constant off-diagonal elements. The approach simply involves randomly choosing a finite order (as large as computationally possible) subset matrix from the original matrix and then diagonalizing the subset. The results are crude, but often informative.

    Notes:
    Azodicarbonamide has been widely used for many years as the blowing agent of choice for expansion of vinyl foams. It has been especially useful in chemically embossed flooring because the sensitivity of the blowing agent to various factors affecting its decomposition temperature permits control of the degree of expansion of the foam. Considerable work has been done by a number of investigators to elucidate these factors. Mechanisms for the decomposition of azodicarbonamide have been proposed in the literature to explain the activating or retarding effect of many compounds on the decomposition temperature. The use of Differential Scanning Calorimetry with an active reference is shown to be an extremely useful tool in determining small effects of various additives on the decomposition temperature of the blowing agent.

    Notes:
    Crystallinity in PVC contributes significantly to the strength and resiliency of the polymer. Two types of crystallites have been described: a primary crystallite in the virgin powder state pictured as a platelet or flat needle-like lamellar crystallite, and a secondary, fringed micellar crystallite from melts or solutions. Both crystallites create loose, crosslinking networks. The secondary crystallite forms when plastisol melts are cooled or solutions are gelled. Crystallites exert a major effect on rheological properties. The thermal destruction of the primary crystallite networks in the melt phase results in a decrease in elastic modulus. Cooling from the fused state creates secondary crystallites that affect tensile and elongation.

    Notes:
    Surface defects in the form of craters have been a sporadic problem for manufacturers of films and coatings made from PVC plastisols. Examination and analysis of plastisols and films from two manufacturers have led to the conclusion that frequently such defects are caused by contamination of one or more of the plastisol components by silicone oil. Silicone oil is immiscible in commonly used plasticizers such as dioctyl phthalate (DOP) and can coalesce in mixing vats or pick up reservoirs to form droplets or pools of oil on the surface of the plastisol. Distribution of the droplets onto the substrate with the plastisol can cause craters to form when the oil dissipates into the melt during fusion.
