  • Method of determining small concentrations of chemical compounds by plasma chromatography
    Patent number: 4259573
    Abstract: An accurate method of determining by plasma chromatography the concentration of an ionizable gaseous or volatile chemical species A in air or another gaseous medium. Small, known increments of species A plus, optionally, another calibrant species are introduced in turn into the plasma chromatograph together with the unknown sample; and the respective changes of the amplitude or area of a characteristic ion peak of species A in the unknown sample are measured. The second, optical calibrant, which is different from species A, must have similar kinetic characteristics but a different ion mobility from the ion formed by A. By means of this technique, inaccurate readings caused by background concentration variations are significantly reduced.

  • Roller bar construction
    Patent number: 4258778
    Abstract: An awning roller bar or lead bar is formed from a relatively thin material for attachment to the leading edge of an awning. In one embodiment, the roller bar includes at least one slideway having an exterior aperture for receiving and securing the edge of a canopy to the tubing. In another embodiment the roller bar has a plurality of planar walls, a pair of interlocking folds and a substantially triangular slideway. If desired, more than one slideway can be formed in the tubing to provide for the attachment of a screen, valance, sunshade or the like. For reinforcement, an expandable material is injected into at least a portion of the tubing core. The expansion and subsequent stabilization of the foamed material strengthens the tubing to provide a roller bar of rigid construction and light weight.
