Frank Diedrichsen 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: 11725663
    Abstract: A rotary piston pump, in particular a claw pump, includes a housing which, when placed in a customary manner, has a housing inlet in a housing upper side. In order to further improve a rotary piston pump in a beneficial way, the housing inlet is connected to a gas channel that is integrated in the housing and extends transversely to a rotational axis of the piston, which gas channel creates a flow connection to a gas outlet of a filter part arranged in a filter receptacle. In the installed state, the filter part is accessible from a side perpendicular to the housing upper side, for maintenance purposes, for example.

  • Publication number: 20110150637
    Abstract: A radial fan, preferably a high-speed radial fan, includes a blower wheel, a housing which receives a rotor and a stator of an electrical drive of the blower wheel shaft, and a cooling system. To develop one such radial fan in terms of the cooling system required, paths for a first cooling medium and a second cooling medium are provided in the housing, the second cooling medium being cooled by the first cooling medium as provided for by the housing, and the paths are separated from each other by intact material walls of the housing.

  • Patent number: 7922466
    Abstract: The invention relates to a radial fan (1), preferably a high-speed radial fan, comprising a blower wheel (8), a housing (2) which receives a rotor (6) and a stator (5) of an electrical drive (4) of the blower wheel shaft (7), and a cooling system. The aim of the invention is to develop one such radial fan in terms of the cooling system required. To this end, paths (30, 37) for a first cooling medium (K1) and a second cooling medium (K2) are provided in the housing (2), the second cooling medium (K2) being cooled by the first cooling medium (K1) as provided for by the housing (2), and the paths (30, 37) are separated from each other by intact material walls (40) of the housing (2).

  • Patent number: 5364228
    Abstract: A turbine including a radial compressor having radial blades, with the compressor supplying side channel compressors arranged at its circumference and having chamber blades. To increase the efficiency, the chamber blades and the radial blades are curved in opposite directions, with the chamber blades and radial blades having a curvature transition point at their transition area, and the blades, in the transition area, are inclined by an identical angle of less than 30.degree. and, for example, 15.degree. relative to a circumferential tangent in the transition area.

  • Patent number: 5303253
    Abstract: A compact flowing gas laser, particularly a CO.sub.2 gas laser, wherein the path or paths between the outlet or outlets and the inlet or inlets of one or more optical resonators contain a turbine whose impeller or impellers are driven by heated gas and which drives the impeller or impellers of a rotor forming part of a compressor serving to compress the thus cooled and expanded gaseous lasing medium prior to reentry into the resonator or resonators. A first heat exchanger is installed between the turbine and the compressor, and a second heat exchanger is provided downstream of the compressor.
