Abstract: A minimized journaling mechanism stores minimized journal data in a format that allows for display and outputting the journal data in human-readable form. When a change to a record occurs, instead of writing only the changed bytes, all of the bytes in each field that changed are written to the journal, along with all of the bytes in each field selected to be always journaled. A default object is created with default data in all of the fields. When the journal entry needs to be output in human-readable form, the default object is read, and the minimized journal entry is then overlaid on the default object. The result is an object that contains default data in all non-selected fields that were not changed, with the journal data in all fields and that did change and in all fields that were selected to always be journaled.

Abstract: A method of decreasing the concentration of nitrogen oxides in a combustion gas flowing through a vessel including the steps of: generating a flue gas in a combustion zone of the vessel, the flue gas containing nitrogen oxides and carbon monoxide; providing overfire air into a burnout zone of the vessel from a first injector of the overfire air to oxidize at least some of the carbon monoxide in the flue gas; injecting a selective reducing agent concurrent with the overfire air at a level in the burnout zone downstream of the first injector of overfire air and downstream of the oxidization of the carbon monoxide; and reacting the selective reducing agent with the flue gas to reduce the nitrogen oxides.

Abstract: A method of decreasing the concentration of nitrogen oxides in a combustion flue gas in which a nitrogen reducing agent is introduced together with the overfire air to mixes with the products of primary combustion along with the overfire air. The nitrogen agent reduced NOx as it passes through the temperature regime that is optimum for the NOx reduction as overfire air and flue gas mix. The transition from low to high temperature effectively eliminates ammonia slip. Additionally, the nitrogen agent may be mixed with the overfire air stream in such a manner that it is optimally shielded from early mixing with the products of primary combustion, where a portion of the overfire air reacts initially with any residual carbon monoxide (CO) that would otherwise interfere with the NOx reduction chemistry.

Abstract: A temperature control pack for refrigerating a shipping container includes a mass of gel material which is shape-retaining at room temperature, and is configured as a relatively thick rectangular solid. The mass of gel material is enclosed in a first plastic film bag, and also in a second plastic film bag providing a sheath about the first bag, and also enclosing a quantity of air to provide an insulating and cushioning air space between the bags. Especially at the ends of the mass of gel material and surrounding bags, an air cushion space is provided in order to safeguard the plastic bags against bursting caused by “water hammer” effect from dropping, impacts, or jarring of the shipping container. The thick rectangular shape of the mass of gel material, along with the pair of plastic film bags, in combination with the insulating air space, provide a leak-resistant temperature control pack with increased refrigerating endurance.

Abstract: An index recovery mechanism recovers all indexes that were journaled and may be fully recovered during IPL. In addition, the index recovery mechanism performs a first stage of processing for any index that was journaled but cannot be fully recovered during IPL. The first stage processing includes storing index recovery data for an index during IPL. Once IPL is complete, the index recovery mechanism performs a second stage of processing by reading the index recovery data that was stored during IPL, and completing recovery of the index. By performing this two-stage index recovery, the first stage during IPL and the second stage post-IPL, indexes that cannot be fully recovered during IPL can still be journaled and recovered.

Abstract: Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.
