  • Patent number: 10570874
    Abstract: A method of operating an internal combustion engine with at least one piston-cylinder unit, and preferably a plurality of the piston-cylinder units, whereby, in a detection mode of the internal combustion engine one or more knock-promoting measures are taken until knocking has occurred in at least one piston-cylinder unit, and the measure(s) is/are intensified until a termination criterion is reached, whereby it is detected in which of the piston-cylinder units knocking has occurred, and whereby, in piston-cylinder units detected as knocking, the ignition time for a normal operating mode of the internal combustion engine is retarded.

  • Patent number: 10422718
    Abstract: A test appliance and a method for testing a mirror, e.g., a mirror of a microlithographic projection exposure apparatus. The test appliance has a computer-generated hologram (CGH), and a test can be carried out on at least a portion of the mirror by way of an interferometric superposition of a test wave that is directed onto the mirror by this computer-generated hologram and a reference wave. Here, the computer-generated hologram (CGH) (120, 320) is designed in such a way that, during operation of the appliance, it provides a first test wave for testing a first portion of the mirror (101, 301) by interferometric superposition with a reference wave in a first position of the mirror (101, 301) and at least a second test wave for testing a second portion of the mirror (101, 301) by interferometric superposition with a reference wave in a second position of the mirror (101, 301).

  • Patent number: 10337850
    Abstract: A measurement arrangement (10) and an associated method for interferometrically determining the surface shape (12) of a test object (14) includes a light source (16) providing an input wave (18) and a diffractive optical element (24). The diffractive optical element is configured to produce in each case by way of diffraction from the input wave a test wave (26), which is directed at the test object (14) and has a wavefront that is adapted at least partially to a desired shape of the optical surface, and a reference wave (28). The measurement arrangement furthermore includes a reflective optical element (30) that back-reflects the reference wave (28) and a capture device (36) that captures an interferogram produced by superposing the test wave after interaction with the test object and the back-reflected reference wave (28), in each case after a further diffraction at the diffractive optical element in a capture plane (48).

  • Patent number: 10307930
    Abstract: A guide bar for a saw chain includes an elongate, flat base body made of a basic material. The base body extends along a longitudinal center axis and, in order to guide a saw chain, has a running surface formed on an outer periphery thereof and a guide groove formed in the outer periphery of the base body. The guide groove has a groove base. A direction-reversing section for the saw chain is provided at one end of the base body. The direction-reversing section includes at least one add-on component having a running surface made of more wear-resistant material than the basic material of the base body. The add-on component is secured to the base body of the guide bar by at least one weld seam. The weld seam extends between the add-on component and the base body and is located spatially beneath the groove base.

  • Patent number: 10008847
    Abstract: The present invention concerns a circuit arrangement for thermal protection of a power semiconductor, wherein there is provided a two-stage thermal protection in the control circuit and in the load circuit of the power semiconductor. A first stage (10) with temperature-dependent resistance device serves for reducing or switching off the control voltage of the power semiconductor (30) when a first threshold temperature is reached at the temperature-dependent resistance device. In addition, provided in the load circuit of the power semiconductor (30) is a second stage (20) with a cutout element thermally coupled to the power semiconductor (30) for interrupting a load current of the power semiconductor when a second threshold temperature is reached at the cutout element. In that case the first stage forms an active temperature protection for the power semiconductor (30) to avoid damage and the second stage forms a temperature protection in the case of a malfunction of the power semiconductor (30).

  • Patent number: 9771892
    Abstract: A method of starting up a thermoreactor arranged in an exhaust gas flow of an internal combustion engine includes igniting combustion gas by spark ignition in at least one cylinder of the internal combustion engine. The exhaust gas resulting from the combustion of the combustion gas is fed at least partially to the thermoreactor as an exhaust gas flow. The temperature of the exhaust gas resulting from combustion of the combustion gas is increased by the moment in time of the spark ignition being selected later in comparison with a present moment in time.
