  • Patent number: 10661886
    Abstract: The invention relates to a wing structure (1) for flying objects, comprising a wing leading edge (4) and a wing box (2), wherein the wing leading edge should be arranged on the wing box in particular in a detachable manner. For this purpose, the wing leading edge is connected to the wing box within a joining segment (9) and to rib extensions (11) of the wing box by means of fastening element (12) near the nose segment (15) such that a fastening-free segment (14) extends on the top side (16) of the wing leading edge in order to compensate thermal deformation during flight.

  • Publication number: 20200029805
    Abstract: An ophthalmic surgical microscope includes a main objective lens, through which an observation beam path passes, and a confocal optical system configured as a refractometer to determine the refraction of an eye. The optical system includes a measurement light source to generate a measurement light beam, a light detector to measure an intensity of measurement light and an optical unit to direct the measurement light beam onto the retina of the eye and to return measurement light reflected back at the retina to the light detector. The optical system includes an adaptive optical module (AOM) to modify a wavefront of the measurement beam path such that an intensity of the back-reflected measurement light changes. A spherical equivalent (SE) of the ametropia of the eye is determined based on a setting of the AOM, at which the measured intensity of the back-reflected measurement light has a maximum.

  • Patent number: 9555683
    Abstract: A four-point link for the suspension of a rigid axle which has four bearing seats. Two bearing seats can be articulated on the axle and two can be articulated on the vehicle frame. The link has a single-piece link body which is inscribed by the trapezoid formed by the bearing seats. The link body is formed of a fiber-composite arrangement that comprises at least one longitudinal fiber arrangement. The longitudinal fiber arrangement encases the bearing seat, at least along half circumference thereof and extends along at least a portion of the link body in order to optimize loading, reduce mass and increase its application. Torsional compliance makes it possible to use relatively small and/or hard rubber bearings for articulating the four-point link or the vehicle axle.

  • Patent number: 6382649
    Abstract: A suspension for a wheel in a motor vehicle, such as a passenger car, having a link which is made of fiber composite and is mounted at one end, by means of a mounting, on a chassis of the vehicle and at the other end holds the wheel, and having spring means which are made of fiber composite and support the link on the chassis in a resilient manner. In order to obtain a particularly compact construction for the wheel suspension, the mounting has a bearing in which a bearing part, which is fastened to the chassis, is mounted such that it can be adjusted relative to a bearing part, which is fastened to the link, by pivoting about a pivot axis, and the spring means having a torsion-bar suspension which extends coaxially to the pivot axis and is fastened at one end to the chassis or to the bearing part fixed to the chassis, and is fastened at the other end to the link or to the bearing part fixed to the link.

  • Patent number: 4932821
    Abstract: A nail retaining strip for feeding nails into a fastening element driving tool where the nails are driven individually out of the tool by a drive piston includes guide bushings for the nails. Adjacent guide bushings are separably interconnected by connecting webs. The guide bushing extends in the axial direction of the nail shank and has axially and circumferentially extending circular guide surfaces for supporting the nails within the muzzle bore of the driving tool. The connecting webs extend radially outwardly from the guide surfaces so that the guide surfaces on adjacent guide bushings are in spaced relation. The connecting webs retain the nails in the axial direction of the muzzle bore by engagement in a receiving recess in the bore located opposite a passage through which the nails are inserted into the bore. Such axial retention permits complete utilization of the nail strip down to and including the last nail.
