20090321178 | METHOD AND SYSTEM FOR DAMPED ACOUSTIC PANELS - A method and system for an acoustic panel system are provided. The system includes a plurality of acoustic panel segments aligned circumferentially about an inner diameter of a fan containment case wherein each segment includes a radially inner surface defining a portion of a fluid duct, a radially outer surface defining a gap between the fan containment case and the acoustic panel segment, and an aft end lip configured to be inserted into a mating groove in the fan containment case. The system also includes at least one damping bumper coupled to the radially outer surface wherein the bumper extends from the radially outer surface to the fan containment case and comprises an energy absorbing elastomeric material configured to facilitate dissipating a forced response of a vibratory stimulus. | 12-31-2009 |

20120197043 | METHOD OF PURIFYING A DICARBOXYLIC ACID - A process for purifying a dicarboxylic acid that is derived from the mixed oxidation products from an ozonization of a mixture containing an ethylenically unsaturated compound having between 6 to 24 carbons, the process includes distilling the mixed oxidation products to provide a first distillate, and a second distillate, where the second distillate includes the dicarboxylic acid and impurity acids, partitioning the second distillate between water and a organic solvent, separating the organic solvent layer from the water layer, lowering the temperature of the water layer to crystallize at least a portion of the dicarboxylic acid, separating the crystallized dicarboxylic acid solid, melting the crystallized dicarboxylic acid, and distilling the liquid dicarboxylic acid to provide a purified dicarboxylic acid. | 08-02-2012 |
