A portable gas fractionalization apparatus that provides oxygen rich air to patients is provided. The apparatus is compact, lightweight, and low-noise. The components are assembled in a housing that is divided into two compartments. One compartment is maintained at a lower temperature than the other compartment. The lower temperature compartment is configured for mounting components that can be damaged by heat. The higher temperature compartment is configured for mounting heat generating components. An air stream is directed to flow from an ambient air inlet to an air outlet constantly so that there is always a fresh source of cooling air. The apparatus utilizes a PSA unit to produce an oxygen enriched product. The PSA unit incorporates a novel single ended column design in which all flow paths and valves can be co-located on a single integrated manifold. The apparatus also can be used in conjunction with a satellite conserver and a mobility cart.

Improved micro-columns and methods for producing micro-columns particularly suitable for use in gas chromatographs are disclosed. In particular, following deposition of the stationary phase coating, the micro-columns are subjected to a postcoating treatment with a molecule that binds to the active sites in the stationary phase micro-column thereby eliminating or reducing loss of gas chromatograph performance associated with those active sites. The postcoating treatment molecule binds to the same active sites as the analytes of interest.

The disclosed HPLC column is formed with overlying concentric inner and outer tubes. The flow path is established via the inner tube bore that holds packed absorbent, end filters and capping sealing members, and end coupling members cooperate with the inner tube at its ends. The sealing and end coupling members have conventional configurations for establishing a sealed connection with capillary lines and their fittings, for the series flow testing use through the column. The inventive method and manner of assembly provides that the outer tube overlies all of the inner tube and both sealing members, but only part of each end coupling member. The ends of the outer tube are then deformed radially inward to become mechanically interlocked with the end coupling members, as the column, holding also the filters and sealing members within the inner tube.

The preferred embodiment of the present invention contemplates a system for elevating a lift crane above the deck and about the leg of the jack-up structure, without relying upon the leg for structural support. A structurally reinforced jack-house having jacking units interfacing with the leg is provided at the deck of the vessel the jack-house configured to engage and support a crane tube column upon the roof of the jack house, which crane tube column in turn has situated thereupon the lift crane. The combined jack-house/crane tube column design allows one to support a crane above the deck in a stable manner independent of the leg situated therethrough, so as to provide a superior structural support for the lift crane, while providing ample space within the jack-house for the jacking units. The combined jack-house/crane support structure thereby affords significant space savings upon deck of the platform, while providing enhanced support of the lift crane. The substructure of the vessel comprises longitudinal and transverse bulkheads intersecting to form a support cell having a perimeter, the portion of the bulkheads forming the cell extend vertically through the deck to form the walls of the jack house and support for the platform. In an alternative embodiment, a truss-type bracing assembly engages the perimeter of the support cell below deck to form a raised platform without walls.
