    The intensity distribution and variance of the iron Kα multiplet (1969)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: The variance of the Kα12 doublet of iron X-radiation as a function of truncation range was determined using a silicon analysing crystal. The presence of satellite lines gives rise to an initial `pseudolinear' part to the variance–range curve; the origin and significance of this part are discussed. The effect of the satellite group was removed by interpolation of the line profile. The possibility of locating the background level by computation is investigated; it is shown that a mis-setting in the background level has an appreciable effect on the variance function, whilst a mis-setting in the background slope has negligible effect on the slope of the variance function. Results for both filtered and unfiltered radiation are given.

    Variation of Breakdown Voltage of a Positive-point/Plane Gap with Applied Voltage Waveshape (1965)

    Notes: [Auszug] It was suggested1 that the phenomenon might be due to pre-breakdown corona mechanisms which are dependent on time and could therefore vary with rise-time of any applied impulse voltage. During the discussion on a paper6 concerning the difficulties of installing a 400-kV grid-system in England and ...

    Surface tensions of liquid polyisobutylenes (1968)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 12 (1968), S. 2213-2224

    Notes: Measurements of surface tensions were carried out in the temperature range 25-120°C on seven different liquid polyisobutylenes with molecular weights ranging from 100 to 80,000. Relationships between the surface tenstion of polyisobutylene and other properties, such as the parachor, cohesive-energy density, and molecular weight are discussed.
