20080302059 | Filling Fenestration Units - A method for fabricating an insulated system such as, for instance, an insulated window unit, includes introducing an insulating material between adjacent walls and stabilizing the system. Particulate insulators preferably are introduced in the system by filling an expanded internal volume. Stabilization of the system can be carried out by reducing the pressure within the internal volume. A stabilized insulated system is fabricated by introducing an insulating material between adjacent walls and stabilizing the system. Also disclosed are processes and equipment for filling insulated systems, such as fenestration units, and insulated systems comprising mixed insulating materials. | 12-11-2008 |

20130291686 | SULFIDE ORE LEACHING PROCESS - The present invention discloses a new process for leaching sulfide minerals consisting of leaching crushed ore in a vat reactor, wherein the leaching solution is fed with an ORP value close to the upper limit suitable for leaching and the exiting leaching solution leaves the reactor with an ORP above the lower limit suitable for leaching the ore. The output leaching solution that leaves the leaching reactor goes through an iron oxidation stage outside the leaching reactor, with the iron oxidation producing soluble ferric sulfate that is mixed with a recirculated portion of the output leaching solution to increase its ORP up to a value close to the upper limit of the redox potential range that is suitable for the ore leaching. | 11-07-2013 |

20150361959 | ADJUSTED OPERATING TIME - A method for determining an adjusted operating time of a component in a rotating system, the method comprising steps of: during operation of the rotating system, measuring a value of an operating characteristic of a component for a predetermined period of time, determining an average of the measured value of the operating characteristic for the predetermined period of time, determining a ratio of the average and a maximum value of the operating characteristic, and determining the adjusted operating time as the product of the ratio and the predetermined period of time. The method is also adapted to a system. | 12-17-2015 |
