摘要： A method of operating a train system for driving a mechanical driven equipment is disclosed. The train system comprises a hybrid gearbox connected between a power source and a load to be driven. The hybrid gearbox includes a lay shaft gear, which transmission ratio between the power source and the load and a motor-generator unit can be adjusted, to adjust the transmission speed ratio arranged, to balance the power generated by the power source and to improve the efficiency of the train system in a number of operating conditions.

摘要： The composite seal structure includes a carrier ring and a seal element housed in an annular groove formed between a circumferential outer wall and two side walls of the carrier ring. The seal element has a first region in surface-to-surface contact with the annular groove and a second, seal-ing region protruding from the annular groove. A fastening arrangement couples the seal element and the carrier ring to one another. The fastening arrangement comprises a plurality of fastening pins circumferentially arranged around the axis of the carrier ring. Also disclosed is a method for manufacturing the seal structure.

摘要： A motor-driven compressor equipped with multiple compression sections, the motor-driven compressor including, at least one housing, at least two drive shafts, the at least two drive shafts being rotatably supported in the housing by at least two bearings, a flexible coupling device connecting the drive shafts, an electric motor mounted on a first compression shaft of the at least two drive shafts, and at least two compression sections. A first compression section of the at least two compression sections is cantilevered at a free end of a first compression shaft of the at least two drive shafts, and a second compression section is mounted between two bearings on a second compression shaft of the at least two drive shafts.

摘要： A pressure regulator is configured for better accuracy and response times at higher inlet pressures. These configurations may integrate two-path control with a pressure-balanced plug. The two-path control may leverage a pair of pilot valves, one with a fixed differential pressure and the other with a variable differential pressure. In one implementation, the device is plumbed so that downstream pressure is sensed at both the actuator and the variable differential pressure pilot valve.

摘要： A sealed connection device configured to connect a pump head with a pump on an additive pump. The sealed connection device may comprise an adapter and a sealing collar that inserts into the adapter. The sealing collar may comprise a body with a bore forming open ends, a shoulder disposed between the open ends, an annular detent adjacent the shoulder, annular grooves, one being disposed on the shoulder two others found on either side of the shoulder, and o-rings disposed in the annular grooves. The pump may couple with a first side of the adapter, the pump comprising a shaft that inserts in the bore of the sealing collar. The pump head may insert into a second side of the adapter so as to contact one of o-rings on the sealing collar.

摘要： A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

摘要： A sensor unit that is configured to improve the non-contact, magnetic interface on a gas meter. The configurations may include a pair of magnets that co-rotate in response to a magnet internal to the gas meter. At least one of the magnets may also move longitudinally in proximity to the internal magnet. This feature aligns the magnets with one another to ensure proper magnetic coupling with the internal magnet.

摘要： A gas meter is outfit with near field communication (NFC) devices for in-situ exchange of data. The NFC devices reside in separate compartments. A first compartment houses electronics necessary to generate values for volumetric flow of material in a pipe. The gas meter includes a second compartment with an access point that allows data, including telemetry data, to transmit from the gas meter to a remote device. In operation, the NFC devices exchange data between the first compartment and the second compartment, often through a wall or barrier that prevents flow of fluid between the compartments.
