摘要： A submersible, high-voltage electrical connector that includes a female connector and a male connector. The female connector has an interior chamber and a conduit configured to connect the interior chamber to an evacuation pump. The male connector is configured to fit within the chamber of the female connector. The conduit of the female connector is further configured to, when the male connector and the female connector are mated, substantially evacuate any liquid from the chamber of the female connector.

摘要： A synchronous-reluctance, rotary motor-generator having a rotor, a stator, a radial air gap positioned radially between the stator and the rotor, and a conductor winding assembly. The rotor has an even number of crescent rotor poles with a gap between adjacent crescent rotor poles. Each crescent rotor pole is non-symmetric about a radially-oriented centerline of the rotor ferromagnetic flux path. Each low-reluctance direct axis of the rotor passes through at least one of the gaps between the crescent rotor poles. Each crescent rotor pole is positioned tangentially to the radial air gap. The stator is on a common center with the rotor. The stator has a stator salient pole between each coil winding slot and positioned tangentially to the radial air gap. Each stator salient pole is non-symmetric about a radially-oriented centerline of the stator-salient-pole.

摘要： The inventive technology, in particular embodiments thereof, may be described as an apparatus (e.g., a pump) that imparts work to and redirects a fluid, and that features an impeller configured to contact and redirect an impeller inflow along a toroidal flowpath to generate an impeller discharge that has both axial and tangential velocity components, where the axial velocity component is substantially 180 degrees relative to a direction of an impeller inflow, in a meridional plane, the apparatus also featuring a diffuser having a diffuser axis that is aligned with an impeller axis of rotation, the diffuser featuring a diffuser outlet annular radial size that is greater than a diffuser inlet annular radial size; and/or curved diffuser vanes established as part of the diffuser, that redirect the impeller discharge so as to reduce the tangential velocity components.

摘要： A fluid connection for a hydromotive machine or fluid-control valve having a first duct and a second duct. The first duct includes a mid-portion between a first end of the first duct and a second end of the first duct that has a non-circular cross-section. A second end of the first duct is wholly within the second end of the second duct. A first end of the second duct is wholly outside of the first duct.
