Abstract: An electric turbomachine for use with an internal combustion engine, a turbocharger or a fuel cell e-compressor includes a high-speed electrical machine located internally within a housing that is arranged to be rotationally driven by a shaft about a rotational axis; a compressor that is arranged to compress fluid within a turbo compressor when it is rotationally driven about the rotational axis by the shaft; a power electronics assembly that is arranged to supply power to the electrical machine; and a control assembly that is arranged to control the power supplied by the power electronics assembly to the electrical machine. The power electronics assembly is mounted externally on the housing on a first surface of the housing, and the control assembly is mounted externally on the housing on a second surface of the housing.

Abstract: Turbomachinery comprising a turbine housing (200) with an engagement formation (210) and a casing (400) for electrical machinery, the casing (400) including an engagement recess (410). Furthermore, the engagement recess (410) comprises a cantilever member (420) and is adapted to receive the engagement formation (210). Finally, the engagement recess (410) and engagement portion (210) are configured such that during operation of said turbomachinery the engagement formation undergoes thermal expansion to expand relative to the engagement recess and exert pressure on the cantilever (member 420). In this way, an improved apparatus for centralising the turbine housing (200) in relation to the casing (400) is provided.

Abstract: An improved rope socket for downhole operations, capable of separating within the wellbore to permit removal of upper components and attached wireline, while lower components including an uphole-facing fishing neck remain attached to a tool string or fish within the wellbore. Also, an improved drop bar for actuating a release mechanism of the improved rope socket. The improved drop bar includes wheel assemblies having integrated axles to provide a stronger axle capable of offset placement along the circumference of the drop bar.

Abstract: Computer-implemented methods, systems and apparatus are provided for sharing information between a group of vehicles that includes a first vehicle and one or more other vehicles. Each of the vehicles includes an onboard computer system that includes a computer processor, a receiver, a transmitter, and a tangible, non-transitory computer-readable storage medium. The storage medium stores instructions that, when executed by the processor, cause the processor to perform various acts. In accordance with the method, an onboard computer at the first vehicle generates information and automatically communicates that information to the other vehicles of the group of vehicles. Upon receiving this information at each of the other vehicles, the information can be processed at the onboard computers of each of the other vehicles, and then presented via human machine interfaces that are disposed within or inside each of the other vehicles.

Abstract: A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug, may be used to set a packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may use a flapper mechanism to regulate passage of fluids through the housing, and a piston and/or flow tube may also be utilized to lock the flapper in an open or closed orientation within the housing.

The tool may also contain a pressure-regulating assembly for regulating the differential pressure across the assembly. The tool may also include an indicator assembly for confirming that the tool has entered a plugging configuration, typically by altering a pressure within the tubing, such alteration being detectible at a surface location.

Abstract: A method and apparatus for removing gas lift valves when the valve is stuck in a side pocket mandrel positioned in an oil and gas well. The method includes the running of an elongated tool body into the well on a slick line, wireline or the like. The tool body is extended into the side pocket mandrel sufficiently so that the distal end of the tool body is located at an elevational position below the gas lift valve to be removed. A valve removal arm extend laterally from the tool body and into the lower end portion of the side pocket portion of the side pocket mandrel, at a position directly below the gas lift valve. The tool body is lifted until the valve removal arm engages the bottom of the gas lift valve. Continued application of tension to the wireline lifts the tool body and the valve removal arm that is engaged with the bottom of the as lift valve, thus dislodging the stuck gas lift valve from the side pocket portion of the side pocket mandrel.
