  • Patent number: 11965588
    Abstract: A gearwheel includes a gearwheel body with teeth arranged around its rotational axis. Two adjacent teeth are connected to one another at their tooth roots via a tooth base. The gearwheel includes a supporting structure which has a supporting region at least one or both axial ends of the respective tooth base, which supporting region extends away from the tooth base between the respective adjacent teeth. The supporting regions are connected directly to the adjacent teeth and the tooth base in each case by way of a transition region. The respective transition region surrounds the supporting region in a manner which extends at least partially and contiguously and has a transition geometry in cross section as viewed in the direction of its extent. A geometric variable of the said transition geometry changes steadily, depending on the supporting region, along an axial and/or radial direction with regard to the rotational axis.

  • Patent number: 11731428
    Abstract: The invention relates to a capping unit (1) for capping at least one printhead (311.1, 311.2, 311.3, 321.1, 321.2, 321.3) of a printer (300), in particular an inkjet printer. The capping unit (1) includes a belt element (2.1, 2.2) having an elongated extent, wherein the belt element (2.1, 2.2) includes at least one flexible cap (3.1, 3.2) for capping the at least one printhead (311.1, 311.2, 311.3, 321.1, 321.2, 321.3), wherein the belt element (2.1, 2.2) features a resting setting and a capping setting and is displaceable from the resting setting to the capping setting and back. The belt element (2.1, 2.2) provides a self-stability section (5.1, 5.2) extending over at least a portion of the belt element (2.1, 2.2)'s elongated extent, wherein in the self-stability section (5.1, 5.2), the belt element (2.1, 2.2) is bendable in a movement plane (13.1, 13.2). In the capping setting, at all positions within the self-stability section (5.1, 5.2), a course of the elongated extent follows a straight line (14.1, 14.

  • Patent number: 4101480
    Abstract: Liquid additive, which is substantially insoluble in water, for a pigmentary printing paste for use in printing on textile fibers and fabrics, wherein the additive comprises a surface-active, non-ionic liquid product having a molecular weight of between 1,000 and 20,000 and formed by condensing one or more alkylene oxides, and preferably propylene oxide, with a compound having one or more atoms of active hydrogen. The pigmentary printing paste is in the form of an emulsion or semi-emulsion of the oil-in-water type and contains a synthetic thickening agent which is soluble in water with a rate of at least 20% of dry material and which is swollen by alkaline agents. The thickening agent is formed by the copolymerization of at least 20% of one or more unsaturated carboxylic acids having 3 to 4 carbon atoms and, if need be, with one or more other unsaturated monomers.
