Gisle Onsrud 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: 10583373
    Abstract: The present invention is directed to both a method for ensuring optimal conditions for separation, and a separator device for extraction of water, oil and gas from a mixture of water-oil-gas flowing in a straight pipe or straight channel. A separator comprises a certain length of pipe with diameter larger than or equal an inlet pipe and several inclined and profiled holes along the separator pipe wall. Holes in the pipe wall at the bottom of the pipe are provided for extraction of water, and one or more groups of inclined holes in the pipe wall at the top of the pipe are provided for extraction of oil and possible gas. Water and oil/gas are separated such that dispersed flow in the inlet is reduced to velocity equal or less than that of the separated flow at the outlet of the separator.

  • Patent number: 8466576
    Abstract: A generator (20) for in situ fluid-driven production of electric energy and also a method of making the generator (20), which comprises a stator and a rotor. The stator is formed as a turbine housing (1) having at least one internal cavity (2) within which at least one independent rotor body (3) is arranged without a fixed mechanical support in the turbine housing (1). The turbine housing (1) comprises at least one supply channel (8) and at least one discharge channel (9) connected to the cavity (2) for throughput of a generator-driving fluid (13). The cavity (2) is of a circular shape along at least one path of rotation therein, whereas the rotor body (3) is of a rotary-symmetrical shape for allowing rotation thereof along said path of rotation. The turbine housing (1) is provided with at least one coil (5) at the periphery of the cavity (2), whereas the rotor body (3) is provided with at least one permanent magnet (4) at the periphery of the rotor body (3).

  • Publication number: 20120091732
    Abstract: The present invention concerns a power generating apparatus for generating power from a fluid flowing in a pipe (14). The apparatus includes a cylindrical body (13), and an annular turbine (4) for driving an electric generator. Fluid bearings (8, 9, 10) support the turbine (4). A central flow passage (17) extends through the entire power generating apparatus. A fluid conditioner stage removes contamination of solid particles from the fluid, for conditioning the fluid before entering the fluid bearing (8, 9, 10), lubricated by the fluid. A first static flow shaper (1) is included in the fluid conditioner stage for providing a rotating vortex flow acting to concentrate the contamination of solid particles in a flow along an outer circumference of the apparatus and an uncontaminated flow to the bearings (8, 9, 10).

  • Patent number: 5971604
    Abstract: A mixer for a fluid flow in a pipe connection, especially for homogenizing a multiphase flow, has a housing to be inserted in the pipe connection for the fluid to flow through. In the housing there are at least one and preferably two or more adjoining and individually displaceable regulating elements having cooperating wall portions with flow passages. At an upstream side radial flow passages cause the fluid to converge into a central chamber. In the cooperating wall portions, a number of flow channels can be aligned or misaligned with one another and/or the inlet and outlet openings to regulate and control flow by movement of the regulating elements. The regulating elements also define a full cross-section opening at 90.degree. to the flow passages, which can clear the passage between the inlet and outlet for passage of a pipe pig.
