20100025334 | Rehabilitating contaminated water treatment media with resource recovery - Dissolved metals are removed from contaminated water by passing the water through a bed containing media bodies, preferably limestone bodies. Various contaminants carried by the water become associated with the media bodies, thereby inhibiting water flow. The media bodies are rehabilitated by using an excavator, loader, or other machine to scoop them into a bucket having a peripheral wall including a sieve, immersing the container into a liquid held in a wash pit, rotating the bucket so that contaminants abraded from the bodies fall through the sieve into the pit, removing the container from the liquid, and dumping the rehabilitated media bodies from the bucket. When the media bodies have filtered mine drainage containing a particular dissolved metal such as manganese or iron for example, a residue remaining in the basin is a rich source of metal compounds that can be recovered for economic use. | 02-04-2010 |

20150333482 | INDEX-COUPLED DISTRIBUTED-FEEDBACK SEMICONDUCTOR QUANTUM CASCADE LASERS FABRICATED WITHOUT EPITAXIAL REGROWTH - Quantum cascade (QC) lasers and methods of fabricating such QC lasers are provided. The QC lasers incorporate a DFB grating without requiring the use of relying on epitaxial regrowth processes. The DFB gratings are formed as sidewall gratings along the lateral length of the QC active region, or the DFB gratings are formed atop the lateral length of the QC active region, and wherein the top DFB grating is planarized with a polymeric material. | 11-19-2015 |

20080290230 | Electrical component support assembly - An electrical component support assembly that includes an electrical component and a bracket removably attached to the electrical component. The bracket is configured to couple to the electrical component and includes a base member that has a first side with a substantially planar shape. The bracket also includes a pair of elbow members that are located proximate to a second side of the base member. The elbow members are configured to be mounted to a support frame. Each of the elbow members is shaped to include a spring portion and a tab joined thereto. The spring portions flex with respect to the base member. The tabs on the pair of elbow members are arranged adjacent to one another and oriented to extend in a substantially common direction to be received in a common hole in the support frame. The tabs extend outward from the spring portions and have recesses for gripping the support frame. | 11-27-2008 |
