20110247838 | THICK INORGANIC FIBER WEBS AND METHODS OF MAKING AND USING - Monolithic gravity-laid inorganic fiber webs that are greater than about 5 cm in thickness are disclosed. Methods of making and using such webs are also disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a monolithic thick web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers. | 10-13-2011 |
20110247839 | INORGANIC FIBER WEBS AND METHODS OF MAKING AND USING - Gravity-laid inorganic fiber webs and methods of making and using are disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers. | 10-13-2011 |
20110248420 | METHODS OF MAKING INORGANIC FIBER WEBS - Methods are disclosed by which melt-formed inorganic fibers may be processed to form a gravity-laid inorganic fiber web. The gravity-laying process comprises mechanically separating the melt-formed inorganic fibers and collecting the fibers, and may comprise blending the melt-formed inorganic fibers with other inorganic fibers and/or with inorganic particulate additives. | 10-13-2011 |
20110250461 | INORGANIC FIBER WEBS AND METHODS OF MAKING AND USING - Methods are disclosed in which two or more forming chambers are used to process inorganic fibers by gravity-laying methods. The methods may comprise using a first forming chamber to open inorganic fibers and using a second forming chamber to process the opened inorganic fibers, optionally to blend the opened inorganic fibers with additional inorganic fibers and/or with particulate additives, and to collect the inorganic fibers as a mat. The methods may comprise using a first forming chamber to form a first inorganic fiber layer and a second forming chamber to form a second inorganic fiber layer, and consolidating the first and second inorganic fiber layers so as to provide a multilayer gravity-laid inorganic fiber web. | 10-13-2011 |
20120097405 | METHOD OF FIRESTOPPING A THROUGH-PENETRATION USING A FUSIBLE INORGANIC BLENDED-FIBER WEB - A method of firestopping a through-penetration is disclosed, which makes use of a fusible inorganic blended-fiber web. The fusible inorganic blended-fiber web can provide a fire-stopped through-penetration without the use of sealants, intumescent materials, and the like. The fusible inorganic blended-fiber web may comprise a blend of at least first, low melting inorganic fibers and second, high melting inorganic fibers. The fusible inorganic blended-fiber web comprises a bulk density of at least about 7 pounds per cubic foot (0.112 grams/cc). | 04-26-2012 |
20140017504 | Inorganic Fiber Webs and Methods of Making and Using - Methods are disclosed in which two or more forming chambers are used to process inorganic fibers by gravity-laying methods. The methods may comprise using a first forming chamber to open inorganic fibers and using a second forming chamber to process the opened inorganic fibers, optionally to blend the opened inorganic fibers with additional inorganic fibers and/or with particulate additives, and to collect the inorganic fibers as a mat. The methods may comprise using a first forming chamber to form a first inorganic fiber layer and a second forming chamber to form a second inorganic fiber layer, and consolidating the first and second inorganic fiber layers so as to provide a multilayer gravity-laid inorganic fiber web. | 01-16-2014 |
