  • Patent number: 10345569
    Abstract: The invention relates to a zoom objective lens with continuously adjustable magnification, comprising five lens groups, where the first lens group, the second lens group and the fifth lens group are fixed in relation to an object. The third lens group and the fourth lens group are axially displaceable. The following conditions apply to the lens: the variable air gap between the second lens group and the third lens group decreases or has a turning point with a transition from a low to a high magnification ?, the refractive power of the second, third and fifth lens groups is positive and the refractive power of the fourth lens group is negative.

  • Publication number: 20190194791
    Abstract: The invention relates to a method for coating a metal strip with the aid of a coating device. Within the coating device, the strip first runs through a coating container with a liquid coating agent and then a stripping nozzle device for stripping off excess coating agent from the surface of the strip. After the stripping nozzle device, the strip typically runs through a strip stabilizing device with a plurality of magnets on both broad sides of the strip. A form control deviation is determined as the difference between a determined actual form of the strip and a specified desired form of the strip and this form control deviation is used for activating the magnets of the strip stabilizing device in order to transform the actual form of the strip into the desired form.

  • Publication number: 20190136864
    Abstract: A sealing arrangement for a centrifugal pump is provided. The sealing arrangement permits a sealing gap between a rotating element such as a pump impeller and a non-rotating element such as a pump casing to be minimized, while protecting against element wear from gap reduction and element contact, particularly during transient operation such as pump start up. At least one of the rotating element and the non-rotating element is provided with a plurality of movably mounted bodies configured to rotate and maintain separate the rotating and non-rotating elements when the sealing gap is reduced. The elements and the bodies may be formed in an additive manufacturing process.

  • Patent number: 10158131
    Abstract: A method for preparing a fuel cell system for a starting operation involves performing a start preparation routine when switching off of the fuel cell system and/or when the temperature falls short of a predetermined temperature threshold value in order to discharge water and moisture from the fuel cell system. The start preparation routine is changed in accordance with measured values detected within a predetermined time interval before the stopping of the fuel cell system.

  • Patent number: 9614238
    Abstract: A fuel cell system includes at least one fuel cell and a humidifying device for humidifying a supply air flow flowing to a cathode chamber of the fuel cell by an exhaust air flow discharged from the cathode chamber of the fuel cell. The supply air flow and the exhaust air flow are separated from one another by water vapor-permeable membranes. An anode water separator, through which exhaust gas from an anode chamber of the fuel cell flows, is integrated into the humidifying device.
