| 20090139403 | WATER REMOVAL DOWNSTREAM OF A TURBINE - A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance. | 06-04-2009 |

In one embodiment the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and preferably organic solvent insoluble. The abuse-deterrent composition prevents the immediate release of a substantial portion of drag, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is broken down or dissolved gradually within the GI tract by a combination of enzymatic degradation, surfactant action of bile acids, and mechanical erosion. | 10-14-2010 |
