摘要： A gas mixing device for a NOx detector includes a 3/2 way gas valve having a diaphragm, a first inlet port, a second inlet port, and an exit port. A gas conduit connects the exit port to a gas mixing chamber. A controller controls the diaphragm to alternate between a first position and a second position. The first inlet port may receive a sample gas and the second inlet port may receive ozone gas. In the first position of the diaphragm, a bolus of sample gas enters the conduit, and in the second position of the diaphragm, a bolus of ozone enters the conduit. The alternating boluses of sample gas and ozone mix within the conduit and within the mixing chamber. A NOx detection instrument includes the gas mixing device, an ozone gas source, and an NO2 sensor in fluid communication with the mixing chamber.

摘要： A submersible sound system may include a housing, an end piece, an elastic membrane, an end cap affixed to the elastic membrane, and a subwoofer speaker system disposed within the housing and supported by a speaker support. A bubble sound source may be defined by the speaker support, the speaker diaphragm, an anterior end of the housing, the elastic membrane, and the end cap. The housing, end piece, and a posterior surface of the speaker support may form a sealed enclosure. The sound system may include a tuning pipe disposed between the sealed enclosure and the bubble sound source. A Helmholtz resonator may be disposed anteriorly of the speaker system. Multiple sound system may be assembled to form a cluster. The cluster may be defined by the vertices of regular polyhedron. The sound systems may be controlled to maintain the speaker systems within acceptable thermal limits.

摘要： Messages on controller area network (CAN) buses are communicated over subsea links to subsea devices that also require electrical power to function. These subsea devices may be disposed kilometers away from the signal source where electrical signal and power transmission is impractical. The present invention provides a subsea power-over-fiber CAN bus converter for converting CAN bus electrical input and electrical power input into optical signals for transmission over a fiber optic cable for conversion into CAN bus electrical output and electrical power output for use by a subsea sensor or other subsea device. The subsea power-over-fiber CAN bus converter of the present invention is may comprise a flying lead harness that has a first connector end, a second connector end, a first optical converter module, a second optical converter module, and a fiber optic cable disposed between the first and second optical converter modules.

摘要： An automatic filter changer that automatically inserts and removes a filter from a fluidic path. Filters are introduced into the automatic filter changer in stacks. The lead filter and each stack is removed from its respective stack one by one by a filter separator. The separated filters are deposited onto a shuttle plate which moves the filters into their respective fluidic paths. Fluid couplers connect to each filter to complete their respective fluidic paths and allow fluids to be filtered before sampling. Once collection of the samples is complete, the filters are removed from the fluidic path and discarded or saved for reuse. The shuttle path is returned to its original position to receive new filters to repeat the process again. A graphic user interface is provided to allow the user to program a specific set of instructions to automate the entire process.

摘要： The present invention provides a fire-resistant electrical feedthrough system for use in offshore and top-side electrical submersible pump (“ESP”) installations. The fire-resistant electrical feedthrough system includes a minimum of two, redundant pressure barriers, in order to provide for safe operation and increased system reliability. The primary barrier is typically embedded within the wellhead equipment structure, while the secondary barrier is typically externally mounted.

摘要： The present invention generally relates to an inline pressure compensator that compensates for volumetric changes within Field-Assembled Cable Termination (FACT) structures when exposed to high pressures and extreme subsea depths by transferring a pressure compensating fluid into the internal cavity of the FACT. The present invention may comprise a flexible internal component and an outer shell-like component. The inner component may comprise two concentric rings of edge-welded bellows that are joined together and wrapped around inner components of the termination or of the inner portion of the outer component. The inner void in the bellows may be filled with pressure-compensating fluid. The pressure compensating fluid diffuses directly into the fluid-filled cavity of the termination assembly. The exterior component may comprise a housing adapted to protect the interior bellows component and provide for seawater to fill the space around the periphery of the bellows arrangement.
