| 20110150717 | MOUNTING MAT FOR EXHAUST GAS TREATMENT DEVICE - A mounting mat for an exhaust gas treatment device includes a wet laid sheet of polycrystalline inorganic fibers that have been physically entangled while the wet laid sheet is still in a wet condition. The exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the mounting mat disposed in a gap between the housing and the fragile structure. Additionally disclosed are methods of making a mounting mat for an exhaust gas treatment device and for making an exhaust gas treatment device incorporating the mounting mat. | 06-23-2011 |
| 20110150715 | Multilayer Mounting Mat for Pollution Control Devices - A multilayer mounting mat for an exhaust gas treatment device including high temperature resistant inorganic fibers, optionally organic binder, and optionally intumescent material. A plurality of the mounting mat plies contain a substantial proportion of the inorganic fibers oriented in the x-y plane of the mounting mat. An exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the multilayer mounting mat disposed in a gap between the housing and the fragile catalyst support structure. | 06-23-2011 |
| 20110097246 | Low Shear Mounting Mat for Pollution Control Devices - A mounting mat for an exhaust gas treatment device including high temperature resistant ceramic fibers containing alumina and/or high temperature resistant biosoluble inorganic fibers, organic binder which at least partially liquefies at elevated temperature prior to binder burnout, colloidal inorganic oxide and optionally intumescent material. The exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the mounting mat disposed in a gap between the housing and the fragile catalyst support structure. | 04-28-2011 |
| 20100173552 | HIGH STRENGTH BIOSOLUBLE INORGANIC FIBER INSULATION MAT - A high strength inorganic bio-soluble fiber insulation mat contains high temperature resistant alkaline earth silicate fibers and optionally additional non-respirable inorganic fibers, wherein the insulation mat has a structure of partially interlocking fibers and an organics content of less than 20 weight percent prior to exposure to temperatures of at least 600° C. A process for producing the insulation mat includes preparing a wet paper or sheet comprising the high temperature resistant fibers and optionally at least one of organic binders or inorganic binders; and intertwining or entangling the fibers in the wet paper or sheet prior to drying. | 07-08-2010 |
| 20100055004 | MOUNTING MAT WITH FLEXIBLE EDGE PROTECTION AND EXHAUST GAS TREATMENT DEVICE INCORPORATING THE MOUNTING MAT - A mounting mat for an exhaust gas treatment device includes first and second major opposite facing surfaces, leading and trailing edges, and opposite lateral edges. At least a portion of one or both of the opposite lateral edges includes an edge protectant that protects the mounting mat against erosion from hot gases encountered during the normal operation of the exhaust gas treatment device. The edge protectant remains flexible after it has been applied to the mounting mat and substantially dried. Also disclosed is an exhaust gas treatment device that includes a housing and a fragile structure mounted within the housing by the mounting mat having the edge protectant deposited thereon. Additionally disclosed are methods of making the mounting mat and an exhaust gas treatment device. | 03-04-2010 |
| 20090060802 | EXHAUST GAS TREATMENT DEVICE - A mounting mat for an exhaust gas treatment device including inorganic fibers, organic binder, antioxidant, optionally clay and optionally intumescent material. The exhaust gas treatment device includes a housing, a fragile catalyst support structure resiliently mounted within the housing, and the mounting mat disposed in a gap between the housing and the fragile catalyst support structure. Additionally disclosed are methods of making a mounting mat for an exhaust gas treatment device and for making an exhaust gas treatment device incorporating the mounting mat. | 03-05-2009 |
| 20090060800 | Substrate Mounting System - A support system for a fragile substrate of an exhaust gas treatment device includes a microporous, inorganic insulating layer, which directly or indirectly engages at least a portion of the fragile substrate: and a flexible fibrous mounting mat which directly or indirectly engages at least a portion of said fragile substrate. The support system may support the fragile substrate of a catalytic converter, a diesel particulate trap filter, a selective catalyst reduction unit, or a NO | 03-05-2009 |
