  • 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.

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.

  • Publication number: 20130252498
    Abstract: A method for obtaining an elongate polysaccharide element, in particular a chitosan thread, includes extruding a hydroalcoholic extrusible solution containing a polyalcohol of said polysaccharide through an extrusion die, coagulating the extruded solution by neutralisation, and at least one operation of removing the polyalcohol. The ratio of water to polyalcohol in the extrusible solution is determined such as to obtain in the elongate element a polysaccharide with the crystalline structure thereof mainly in the form of an anhydrous allomorph. Since the polysaccharide used to prepare the extrusible solution has a weight-average molar mass Mw0, the polysaccharide in the elongate element obtained preferably has a weight-average molar mass Mw1 comprised between Mw0 and 0.7 Mw0. Since the purpose is to obtain a chitosan thread, the latter has properties of mechanical strength and flexibility that allow the thread to be tied into overhand knots and to be woven without breaking.
