  • Method of forming a quadriplanar component
    Patent number: 4173062
    Abstract: A quadriplanar capacitor and the method of forming it is disclosed. A capacitor element is disposed within an open ended enclosure and sealed therein, the enclosure forming one capacitor electrode. The open end of the enclosure forms a quadrilateral. A flat electrode member forming the second capacitor electrode is fixedly attached to a lead which itself is rigidly attached to the capacitor element. The flat member is disposed parallel to the enclosure opening and spaced from the enclosure by the lead. The flat member is substantially coextensive with the enclosure opening.

  • Optical waveguide with protective coating
    Patent number: 4173393
    Abstract: An optical waveguide includes a core of high purity fused silica, a cladding of high purity fused silica and a protective coating of metallic glass. The protective coating is applied as a liquid which contracts more than the glass after it solidifies to place the surface of the glass cladding under compression. Because the waveguide will break only under tension, the force of compression must be overcome before the waveguide can be fractured thereby strengthening the waveguide considerably. The metallic glass coating provides further advantages of abrasion protection and the prevention of fatigue.

  • Detecting Neisseria bacteria
    Patent number: 4166765
    Abstract: Bacteria of the genus Neisseria can be detected in a sample by testing for the presence of an enzyme capable of oxidizing 1,2-propanediol and reducing NAD (nicotinamide-adenine-dinucleotide). The complete structure of the enzyme is not known but, because of those two characterizing properties, the nomenclature 1,2-propanediol dehydrogenase therefor is proposed herein.

  • Controlling the drawing rollers to produce diameter perturbations in an optical waveguide
    Patent number: 4163370
    Abstract: An optical waveguide having variations in diameter is produced by controlling the drawing rollers. Predetermined diameter variations along the length of an optical waveguide reduce dispersion in multimode waveguides. These diameter variations are produced by varying the rotational speed of the pulling rollers, by varying the diameter of the pulling rollers, by moving the pulling rollers axially or by moving a tensioning roller during the drawing process.
