  • Patent number: 11629034
    Abstract: A crane telescope locking device includes a control device which is hydraulically in contact with a telescoping cylinder of a crane telescope and, for the purpose of actuating, with at least one cylinder lock hydraulic cylinder and includes a valve which is open in its inactivated resting state and thus opens a fluidic connection between the telescoping cylinder and the at least one cylinder lock hydraulic cylinder. A telescoping cylinder (6) of a crane includes such a crane telescope locking device.

  • Patent number: 10473460
    Abstract: An overlay metrology system includes a particle-beam metrology tool to scan a particle beam across an overlay target on a sample including a first-layer target element and a second-layer target element. The overlay metrology system may further include a controller to receive a scan signal from the particle-beam metrology tool, determine symmetry measurements for the scan signal with respect to symmetry metrics, and generate an overlay measurement between the first layer and the second layer based on the symmetry measurements in which an asymmetry of the scan signal is indicative of a misalignment of the second-layer target element with respect to the first-layer target element and a value of the overlay measurement is based on the symmetry measurements.

  • Publication number: 20160244327
    Abstract: The invention relates to a plant for at least partly gasifying solid organic input material, with a low-temperature gasifier in which pyrolysis can yield a tar-containing pyrolisis gas from a solid organic input material, and with a high-temperature gasifier having an oxidation unit and an endothermic gasifier, where the pyrolisis gas can be converted to a synthesis gas by partial oxidation in the oxidation unit followed by partial reduction in the endothermic reactor, said endothermic reactor having a form which widens conically in the vertical direction and which has at least one side offtake to take off unwanted particulate solids at not less than one height, more particularly at not less than two or more different heights.

  • Patent number: 8200401
    Abstract: The invention relates to a method of determining changes in loads on lifting gear, whereby a change in load is determined within load curve data at a transition point of the load curve gradient, and whereby the load curve is broken down into discrete-time observation intervals at the transition points. It further relates to a method of reconstructing load situations on lifting gear, for which such a method of determining changes in load is used.
