20090131243 | METHOD FOR THE REACTIVATION OF THERMALLY AGED NITROGEN OXIDE STORAGE CATALYTIC CONVERTERS - Nitrogen oxide storage catalysts are used for removing the nitrogen oxides present in the lean-burn exhaust gas of lean-burn engines. Here, the purifying action is based on the nitrogen oxides being stored in the form of nitrates by the storage material of the storage catalyst during a lean-burn operating phase of the engine and the previously formed nitrates being decomposed in a subsequent rich-burn operating phase of the engine and the nitrogen oxides which are being liberated again being reacted with the reducing exhaust gas constituents over the storage catalyst to form nitrogen, carbon dioxide and water. Storage catalysts are thermally aged by high temperatures. The aging is due to sintering of the catalytically active noble metal components of the catalyst and to formation of compounds of the storage components with the support materials. According to the invention, the formation of compounds of the storage materials can be largely reversed by treatment of the storage material with a gas mixture comprising nitrogen dioxide and/or carbon dioxide and water vapor at temperatures of from 300 to 500° C. The reactivation can be carried out either directly on the vehicle by setting appropriate exhaust gas conditions or during a routine service by removal of the catalyst from the vehicle and treatment with a gas mixture in an appropriate apparatus. | 05-21-2009 |
20110258982 | METHOD FOR THE ON-BOARD REACTIVATION OF THERMALLY AGED NITROGEN OXIDE STORAGE CATALYSTS IN MOTOR VEHICLES HAVING AN INTERNAL COMBUSTION ENGINE OPERATED PREDOMINANTLY UNDER LEAN CONDITIONS - Nitrogen oxide storage catalysts are used to remove the nitrogen oxides present in the lean exhaust gas of lean-burn engines. Storage catalysts are thermally aged by high temperatures. Ageing is due to sintering of the catalytically active noble metal components of the catalyst and to formation of compounds of the storage components with the support materials. According to the invention, the formation of compounds of the storage materials can be largely reversed by treatment of the storage material with a gas mixture containing carbon dioxide, optionally water vapor and optionally nitrogen oxides at temperatures in the range from 200° C. to 950° C., preferably from 300° C. to 700° C. The reactivation can be carried out under emission-neutral conditions directly in the vehicle during driving operation by setting of suitable exhaust gas conditions and regulating the air/fuel ratio. | 10-27-2011 |

20120168334 | STERILIZABLE POUCH FOR MEDICAL INSTRUMENTS - An improved sealable pouch has an interior volume for receiving products for sterilization and an integral, foldable flap sealable to the pouch to provide a fully enclosed interior volume. Included on one or more portions of the pouch are indicia, preferably at least a first and second spaced apart indicia, to aid in proper folding of the flap. The indicia provide alignment means so that when the flap is properly folded to provide a leak proof seal, a predetermined portion of the indicia is covered by the flap. An improper seal can be visually determined to exist if all of the indicia or none of the indicia is visible after the seal is made. A proper seal is evidenced by only a portion of the first and second indicia being covered by the flap. | 07-05-2012 |

20080255913 | PEGGING RESOURCES TO SHIPMENTS IN A PRE-EXISTING PRODUCTION PLAN - In software systems for resource-constrained production planning (RCPP), it is often beneficial to determine a detailed association, or “pegging”, between the resources and the shipments that are enabled by those resources. Presented here is a software-implemented method for constructing a pegging of a production plan for an RCPP problem. The method is called “Pegging By Explosion” (PBE). This method, takes a feasible production plan and reconstructs it, using its own specialized incremental allocation technique. A Pegging By Monitoring technique is applied to this reconstruction in order to produce the pegging. The reconstruction is accomplished by a specialized “explosion” technique related to the explosion technique of Material Requirements Planning (MRP). | 10-16-2008 |
