Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

Abstract: An embodiment of the technology described herein is an auxiliary power unit assembly. The auxiliary power unit assembly includes an auxiliary power unit being installable in an aircraft having a cabin, a duct connecting the cabin and the auxiliary power unit, and a noise reduction feature in the duct.

Abstract: A method of fabricating an airfoil is provided. The method includes fabricating at least one airfoil including a suction side and a pressure side coupled together at a leading edge and a trailing edge, wherein the airfoil includes a plurality of first and second chord sections each extending between the trailing and leading edges, wherein at least one of the first chord sections extends outward from the pressure side of the airfoil at the trailing edge, and at least one of the second chord sections extends outward from the suction side of the airfoil at the trailing edge.

Abstract: Methods for facilitating pipeline management, systems, and software, are provided. A method can include forming digitized map segments to provide for display of a geographical relationship between terrain featured in the map segments and a pipeline network, forming pipeline equipment records to provide for detailed engineering analysis on associated pipeline equipment, functionally linking each digitized map segment and each pipeline equipment record to at least one pipeline operational area geographically associated therewith, at least one pipeline geographically associated therewith, or both, and spatially displaying a pipeline equipment work location in relation to one of the map segments.

Abstract: A system for facilitating pipeline management, software, and methods are provided. The system includes a pipeline company computer positioned at a pipeline company site to define a pipeline company server, having a processor, memory coupled to the processor to store software and database records therein, a graphical display coupled to the processor for displaying graphical images and a user interface coupled to the processor to provide a user access to manipulate the software and database records, and pipeline information management analyzing software to analyze pipeline management requirements.

Abstract: A process is disclosed that relates to the removal of impurities and the recovery of a mother liquor and wash filtrate from an oxidizer purge stream produced in the synthesis of carboxylic acid, typically terephthalic. More particularly, the process involves the removal of impurities and the recovery of a mother liquor and wash filtrate from an oxidizer purge stream and then routing the mother liquor and or wash filtrate to an oxidation zone.

Abstract: An inventory control system and method that tracks inventories of items with RFID tags, includes a reader unit and an intelligent station that tracks RFID tags to determine item information of items to be inventoried. The reader unit transmits and receives RF signals. The intelligent station includes a first RF antenna connected to the reader unit by a first transmission cable through a first switch, and one or more additional RF antennae connected to the reader unit by the same first transmission cable through additional switches. An inventory control processing unit receives item information from the intelligent stations to update inventory information regarding the items to be inventoried.

Abstract: An apparatus and method for manufacturing flexible duct comprising feeding a strip of cloth and a channel formed strip of metal in parallel through a work station having a pair of crimping rollers which fasten an edge of the fabric into the channel. A forming ring is provided at the work station to guide a first coil of fabric attached to channel strip around to meet and overlap a second coil of fabric being fed into the work station. A roller member is rotatably fixed above the work station to force the overlapping edges of adjacent coils of fabric down into the channel of the metal strip being simultaneously fed in parallel with the fabric toward the crimping rolls. The roller member carries with it a string which it inserts into the channel over the overlapping edges of the fabric prior to the combined materials being fed into crimping rollers where they are forced into a retained and fixed position within the enfolded arms of the crimped channel of metal.
