Patents by Inventor Thomas Nippert

Thomas Nippert has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10619636
    Abstract: A screw compressor (10) comprising a compressing device (18), in particular, at least one screw-type rotor (20, 22), which feeds a compressed medium to an oil separation device (30). The oil separation device has a first volume (32), a second volume (34) and a separating device (36) that separates the first volume (32) and the second volume (34) from one another. The separating device (36) includes a demister (38) that is located in a first region of the separating device (36). A second region of the separating device (36) is designed as a partition (40) that has one or more oil communication openings (42).

  • Patent number: 4811154
    Abstract: The invention relates to a configuration for rapid detection of short-circuits and for generating an electrical trigger command with an electronic measuring and processing configuration for current values, which compared in a digital comparison circuit with predetermined limit values transmits the trigger command. The measuring configuration determines the current over time as well as the voltage of the grid and the resulting complex impedances and power. In addition to segmentation, standardization and scaling of the current and voltage values, a cross correlation function as well as the respective product and quotient of the Fourier transforms of the voltage and the current for frequency ranges associated with each other are determined, so that a respective power and impedance spectrum are obtained for evaluating the state of the installation.
