| 20110306817 | Method For Processing A Nitrous Aqueous Liquid Effluent By Calcination And Vitrification - A method for treating a nitric aqueous liquid effluent containing nitrates of metals or metalloids, comprising a step for calcination of the effluent in order to convert the nitrates of metals or metalloids into oxides of said metals or metalloids, at least one compound selected from the nitrates of metals or metalloids and the other compounds of the effluent leading upon calcination to a tacky oxide, and a dilution adjuvant leading upon calcination to a non-tacky oxide being added to the effluent prior to the calcination step, a method wherein the dilution adjuvant comprises aluminium nitrate and at least one nitrate selected from iron nitrate and rare earth nitrates. | 12-15-2011 |
| 20120016173 | METHOD FOR TREATING A NITRIC AQUEOUS LIQUID EFFLUENT BY CALCINATION AND VITRIFICATION - A method for treating a nitric aqueous liquid effluent containing nitrates of metals or metalloids, comprising a step for calcination of the effluent in order to convert the nitrates of metals or metalloids into oxides of said metals or metalloids, at least one compound selected from the nitrates of metals or metalloids and the other compounds of the effluent leading upon calcination to a tacky oxide, and a dilution adjuvant comprising at least one nitrate of metal or metalloid leading upon calcination to a non-tacky oxide being added to the effluent prior to the calcination step in order to give a mixture of effluent and of dilution adjuvant. | 01-19-2012 |

| 20100071395 | Portable Cooler - A portable cooler has a thermally isolating outer shell defining an internal compartment for holding contents to be kept cool, such as, for example, food, drinks and temperature-sensitive medicine. The portable cooler has a door connected to the outer shell for providing unrestricted access to the internal compartment. The portable cooler may have a shelf for holding a cold gel pack to help keep the contents cool. The cooler may also have a plurality of dividers (that are optionally reconfigurable) for defining variously sized storage spaces for the contents. The cooler may have an aesthetically pleasing curved outer shell and an adjustable shoulder strap so that the cooler can be carried on a person's shoulder. Because the cooler is easy and comfortable to carry and because its large swing-open door provides full and quick access to its contents, this cooler is more ergonomic and aesthetic than traditional designs. | 03-25-2010 |

| 20110159180 | METHOD AND DEVICE FOR PROCESSING OF GRANULES - This invention relates to a method and device for processing of granules of solidified salts, by forming at least one injection zone in a fluidised bed where a feed stream of seed particles is contacted/coated by the liquid product by simultaneous injection of a feed stream of the seed particles and a feed stream of the liquid product to be sprayed, forming at least one granulation zone in the fluidised bed where contacted/coated seed particles may be dried and/or shaped and/or cooled to form granules, extracting granules from the at least one granulation zone(s) and sorting the extracted granules into three fractions; undersize granules with too small diameters compared to the desired size range, on-size granules with diameters within the desired size range, and oversize granules with too large diameters compared to the desired size range, passing the fraction of on-size granules to post-processing treatment for forming the product granules, removing the oversize, typically by reducing the size of at least a fraction of the oversize granules and admixing them with the fraction of undersize granules, and passing the fraction of undersize granules into the feed stream of seed particles, wherein the granules are made to pass through at least one classifier placed in the at least one granulation zone(s) of the fluidised bed, which segregates the granules according to their size and which passes at least a part of the segregated undersize granules back into the injection zone(s) for further enlargement. The invention also relates to a granulator for performing the inventive method. | 06-30-2011 |

| 20120041090 | PROCESS FOR PREPARING A FLEXIBLE POLYURETHANE FOAM - The process comprises preparing a reaction mixture from a polyisocyanate component and from a polyol component which comprises one or more polyester polyols formed from at least one dimer fatty acid and/or at least one dimer fatty alcohol. In order to improve the processability of the polyurethane flexible foams so that these foams can be produced with the desired hardness and mechanical properties over a broad density range, the isocyanate reactive compounds contain, per 100 parts by weight thereof, 25 to 95 parts by weight of said polyester polyols and 5 to 75 parts by weight of one or more polyether polyols which are free of dimer fatty chains. In this way, no lipophilic filler is needed so that the fogging and emission properties of the foam can be improved. Moreover, softer foam can be produced without having to apply a too low NCO index resulting in better mechanical properties and in particular in a lower compression set. Finally, higher foam densities can be achieved with an isocyanate component having a lower functionality so that the hardness of these foams can be reduced. | 02-16-2012 |
