20150276114 | FLUID TRANSFER COUPLING - A fluid transfer coupling is described that includes first and second connectable coupling members that together contain a sealed interior space when connected. A gas or steam purge inlet and a purge outlet are disposed in fluid communication with the sealed interior space for purging potential contaminants out of the interior space. The coupling also includes a vacuum port in fluid communication with the sealed interior space for drawing a vacuum on the sealed interior space and optionally testing the space for an adequate seal. The first coupling member includes a first fluid transfer conduit and the second coupling member includes a second fluid transfer conduit. The first and second fluid transfer conduits are positioned such that they can be connected together within the sealed interior space when the first and second coupling members are connected. | 10-01-2015 |
20140352324 | DUAL PRESSURE REGULATOR SHUT OFF VALVE APPARATUS - A pre-cooler system is provided and includes first and second pre-coolers, each of which is sized to handle demands of one downstream flow system, a piping system by which the first and second pre-coolers are receptive of compressed air from first and second turbine engines, respectively, and by which the first and second pre-coolers are both coupled to first and second downstream flow systems that are each configured to apply the demands of one downstream flow system to the first and second pre-coolers, a first pair of dual pressure regulator shut off valves (PRSOVs) disposed in parallel with each other and between the first turbine engine and the first downstream flow system, the first pair of dual PRSOVs being arranged in series with the first pre-cooler and a second pair of dual PRSOVs disposed in parallel with each other and between the second turbine engine and the second downstream flow system, the second pair of dual PRSOVs being arranged in series with the second pre-cooler. | 12-04-2014 |
20140292122 | MOTOR COOLING APPARATUS AND METHOD - A driver system, cooling apparatus for a driver system, and method are provided. The driver system includes a driver, a device configured to move a cooling fluid, and a shroud disposed at least partially over the driver. The shroud includes a plurality of inlet orifices and a plurality of outlet orifices in fluid communication with the device, and a plurality of fins extending at least partially between the shroud and the driver, at least partially in the driver, or both, the plurality of fins being spaced apart and defining flowpaths therebetween, wherein the flowpaths communicate with the inlet orifices and the outlet orifices. | 10-02-2014 |
20140221145 | IN SITU GEARBOX GREASING SYSTEM - A method and apparatus for lubricating a gear of a differential gear system is disclosed. A member or shaft rotates within a housing of the differential gear system. The shaft includes a chamber for receiving a lubricant from the exterior of the housing. A gear rotates relative to the shaft, and a hole in the shaft disperses the lubricant from the chamber to a selected gear location of the gear to lubricate the gear. | 08-07-2014 |
20140087584 | ELECTRICAL CONTACTOR ARRANGEMENT WITH THERMAL MANAGEMENT - A power distribution contactor mount, and a power distribution system incorporating the same, include a plurality of electrically and thermally conductive contactor posts operable to connect a contactor lead to a bus bar, a mounting panel face, wherein each of the contactor posts is received in the mounting panel face and extends through the mounting panel face, and a first heat dissipation component mounted on the mounting panel face and thermally connected to each of the contactor posts. The thermal connection is via a thermally conductive and electrically insulative polymer insert, and each of the posts protrudes through the first heat dissipation component. | 03-27-2014 |
