  • Patent number: 11692284
    Abstract: Various implementations include a filament that includes three lobes that extend from a central portion of the filament, and the central portion defines an axial void. Each lobe bulges outwardly at its proximal end adjacent the central portion and has edges that form a continuous concave curve toward its distal end relative to an axis A-A that extends through the distal end of the respective lobe and the central portion of the filament. Thus, a width of each lobe at the proximal end thereof is greater than a width of each lobe at or adjacent the distal end, and adjacent edges of adjacent lobes intersect each other at concave proximal ends of the adjacent edges.

    Abstract: The present invention prescribes a new sol-gel method of preparing and formation of the metal oxide microtubes. According to the method firstly is prepared the precursor sol from metal oxides or mixtures of metal oxides and alkoxides, thereafter from the precursor sol are extruded the fibres, which are gelatinised afterwards until the inner sol which is less viscous of fibres is converted to thinner wall until alcohol from the precursor is left trough walls. The metal oxide microtubes are applicable as to conduct liquids or gasses, as ionic conductors, as catalyst carriers and as light emitters.

    Abstract: A chafe jacket is used with a line extending around a structure comprising a tube structure defining an inner surface and a jacket axis. The tube structure comprises fibers each defining a fiber axis. The fiber axes defined by portions of the fibers defining the interior surface of the tube structure extend at an interior fiber angle of less than approximately 50 degrees relative to the jacket axis. The chafe jacket extends around at least a portion of the line adjacent to the structure to reduce wear on the line.
