20150147248 | PROCESS AND EQUIPMENT FOR PRODUCING PURE LITHIUM-CONTAINING SOLUTION - The invention relates to a process for producing a lithium-containing solution from a lithium-containing raw-material solution, by: a) precipitating a first part of magnesium and calcium from the lithium-containing raw-material solution, b) extracting a second part of calcium and magnesium from the lithium-containing solution by liquid-liquid extraction, a resultant product being a lithium-containing solution. The invention also relates to equipment for producing a lithium-containing solution from a lithium-containing raw-material solution, including a precipitation unit to remove a first part of magnesium and calcium and an extraction unit to receive the lithium-containing raw-material solution and to remove therefrom a second part of calcium and magnesium by liquid-liquid extraction, and control unit to control the operation of the precipitation unit. | 05-28-2015 |

20160115568 | METHOD OF RECOVERING COPPER AND PRECIOUS METALS - Provided is a method of recovering copper and one or more precious metals comprising leaching copper-bearing ore and/or concentrate under atmospheric or slightly pressurized conditions at a temperature below the boiling point of the leach solution in a sulfuric acidic solution in the presence of one or more alkali metal or alkali earth metal halides, whereby the total halide concentration is from 30 to 115 g/L, to dissolve copper and to obtain a leaching liquor comprising copper, sulfur species, and halides in solution. The leaching liquor is then subjected to a solid-liquid separation after which a first aqueous pregnant leach solution and a copper depleted leaching residue are obtained. Copper is purified by solvent extraction from the first aqueous pregnant leach solution to obtain a first copper-containing loaded organic solution and a first aqueous raffinate. The copper containing loaded organic solution is stripped and copper is recovered. | 04-28-2016 |

20150150423 | DISPENSING UNIT AND DISPENSER - A dispensing unit and a dispenser are provided. The dispensing unit is adapted for use with continuous web material. The dispensing unit comprises a first roller arranged to rotate about a first axis and a second roller arranged to rotate about a second axis. A web path is provided through the dispensing unit and a portion of the web path includes a web passage defined between the first roller and the second roller. The first roller is displaceable between at least a first position and a second position, wherein a first distance is defined between the first roller and the second roller when the first roller is arranged in the first position, and a second distance is defined between the first roller and the second roller when the first roller is arranged in the second position. | 06-04-2015 |
20150335211 | DISPENSING UNIT AND DISPENSER - A dispensing unit and a dispenser are provided. The dispenser is adapted for the use with continuous web material. The dispensing unit includes a first roller arranged to rotate about a first axis and a second roller arranged to rotate about a second axis. A web path is provided through the dispensing unit and a portion of the web path consists of a web passage defined between the first roller and the second roller. A drive mechanism engages with at least one of the first roller and the second roller for feeding web material through the web passage. The drive mechanism comprises a feeding ring rotatably suspended in the dispensing unit. The feeding ring extends around the web path. | 11-26-2015 |

20090049491 | Resolution Video File Retrieval - Peer-to-peer and IPTV based technologies have facilitated tremendous growth in terms of the sharing of video files in computer networks and on the Internet. This growth has imposed an immense challenge on service providers in terms of being able to handle continuously increasing loads while still ensuring (a minimum) quality of service. This invention responds to the noted challenge by providing a novel apparatus, method and system for providing video to an end user at various resolutions. Additional benefits include the preservation of computing resources in terms of processing resources, power, and bandwidth while still providing users with content-rich services. | 02-19-2009 |
20090063419 | Discovering peer-to-peer content using metadata streams - Discovering peer-to-peer content using metadata streams involves capturing, for each of a plurality of devices, a content and metadata stream that describes a context of the content. The metadata streams are sent to a metadata repository contemporaneously with the capture of the content by the respective devices. Network queries of the streaming metadata are enable via the metadata repository, and, in response to the network queries, peer-to-peer access of the content is facilitated from one or more of the devices. | 03-05-2009 |
20090259710 | Content distribution - A method and apparatus is configured to generate a first message including a portion of a media stream or a portion of a data file. The method and apparatus also generates a second message including the first message, for sending to one or more addressees. The second message also includes information identifying one or more additional entities other than the one or more addressees from which one or more portions of the media stream or the data file can be obtained. | 10-15-2009 |
