  • Publication number: 20210122103
    Abstract: The invention concerns a method for the production of a composite profiled section (3) comprising a core (1) and a shell (2), in particular intended for use as a reinforcing element or reinforcing rod in a, preferably thermoplastic, plastic material and/or for use as a reinforcing rod for a spring clip (11), wherein the shell (2) has shell fibres (4) which are laid around the circumference of the core (1), wherein, subsequent to the application of the shell fibres (4) to the core (1), at least one supporting fibre (5) is wound around the shell fibres (4) applied to the core (1) by means of a winding device for the production of a preformed pre-composite profiled section (6). As an alternative and/or in addition thereto, a method for producing an aforementioned composite profiled section (3) is provided, wherein the core (1) is produced continuously by foam extrusion with at least one extruder.

  • Patent number: 10610027
    Abstract: An inline method for producing a spring strip profile (1) for a slatted frame that comprises at least one core strand (2) formed by a fiber-reinforced plastic and at least one thermoplastic cover layer (3) surrounding the core strand (2), comprises at least the following steps: joining multiple fibers, threads and/or filaments to form a fiber bundle (2.1); impregnating the fiber bundle (2.1) with a thermally activatable reaction resin; molding the outer contour of the fiber bundle (2.1) impregnated with the reaction resin; thermally activating the reaction resin (2.1) to form a cured core strand; introducing the core strand (2) into an extruder head (110); applying thermoplastic melt in the extruder head (110) to form the cover layer (3) on the spring strip profile (1); and cooling and calibrating the spring strip profile (1) in a cooling and calibrating device (111, 112, 113). The outer contour of the fiber bundle (2.1) is wrapped around, in a winding machine (105), by at least one thread or filament (2.

  • Patent number: 10492953
    Abstract: A planning apparatus for generating control data for an eye surgery treatment device which creates at least one cut surface in the cornea using a laser device. The planning apparatus includes a calculation tool for determining the at least one cut surface in the cornea. The calculation tool determines the at least one cut surface in the cornea based on data from a refractive correction and generates a set of control data that control the laser device for the at least one cut surface in the cornea. The at least one cut surface in the cornea includes an edge and optically effective areas. The calculation tool determines the at least one cut surface in the cornea such the at least one cut surface in the cornea is deeper at the edge than in the optically effective areas.

  • Patent number: 8740889
    Abstract: An ophthalmological laser system and operating method wherein laser-supported operative interventions can be achieved with higher accuracy. The cornea is irradiated with an ophthalmological laser and a detection light confocally recorded, the cornea being scanned in three-dimensions by irradiation with an illuminating laser power using a scanner unit along several directions at several points. Using the simultaneously recorded detection light the position and/or shape of a posterior boundary surface of the cornea is determined. A lamella parallel to the posterior boundary surface can then be cut.

  • Publication number: 20090299930
    Abstract: A method of measuring the thickness profile of a film produced in a blow film line having a rotatable pull-off rig in which a flattened film tube is scanned by performing individual measurements at measurement positions distributed over the width over the film tube and, in each individual measurement, the total thickness of two segments of the film tube is measured that are superposed at the measurement position, the thickness profile is calculated from the measured values obtained for a number individual measurements that is larger than the number of measurement positions, the improvement including the steps of training a neural network with measured values for the total thicknesses, which measured values have been obtained in simulated or real measurement processes with known thickness profiles and supplying the measured results obtained by scanning the film tube to the neural network for calculating the thickness profile.
