20130200182 | PROCESS FOR OBTAINING APATITE CONCENTRATES BY FROTH FLOTATION - A process applicable to different lithologies of phosphate ore with siliceous-carbonated matrix from igneous or sedimentary origin rocks includes ore preparation by comminution through crushing, grinding, and de-sliming, prior to apatite flotation. During flotation, ground and de-slimed ore pulp with high concentration of solids, above 40%, is initially conditioned with depressant reagent, e.g., a vegetable starch gelatinized with sodium hydroxide solution, and conditioning with collector reagent (sulphosuccinate or sulphosuccinamate). This conditioned pulp floats apatite in a circuit with rougher, scavenger, cleaner and recleaner flotation steps. CO | 08-08-2013 |

20120087850 | Process for Obtaining Apatite Concentrates by Flotation - The present invention, named Bunge/Fosfertil process, is applicable at different lithologies of phosphate ore with carbonated-silica matrix from igneous and sedimentary sources, i.e., consists of comminutioning the ore by crushing, homogenization, milling and disliming, prior to the apatite flotation. The dislimed and milled ore pulp with solids concentration above 40%, being initialy conditioned with a depressor reactant, a vegetable source polymer gelled with sodium hydroxide solution; and subsequently, submitted to a conditioning with a scavenger reactant of the sulphosuccinate or sulphosuccinamate groups. This pulp conditioned with reactants goes to the apatite flotation in a circuit comprising the “rougher”, “scavenger”, “cleaner” and “recleaner” steps. In all steps of the circuit flotation the carbon dioxide gas may be added up to saturation of such gas in the temperature and pressure conditions of the pulp. The system to generate bubbles for flotation works independently, being feed with atmospheric air for the self-aspirated machines or compressed air for the flotation cells with air insufflation and notation columns. The final concentrate of apatite is the flotated portion of the last cleaning step of the flotation circuit. | 04-12-2012 |

20090021046 | Articulating interlocking structural extrusions for recreational vehicles and the like - A structural assembly such as for use in constructing a living space of a recreational vehicle includes a wall with vertical rails at the top and bottom. The rails fitting into complementary recess within floor and ceiling members. The bottom rail has a curved cross section and fits into a complementary shaped curved channel in a floor member such that to assemble the wall to the floor, the wall is rested on the floor member at an angle and is then tilted upright to lock it to the floor member. A first keeper is then placed into a gap between the wall and the floor member, and acts in compression to prevent rotation of the wall. A second keeper has portions that fit into recesses in the wall and the ceiling members, respectively. The second keeper acts in tension to prevent vertical separation of the wall and the ceiling. | 01-22-2009 |

20090141032 | Synchronization of video input data streams and video output data streams - A method for synchronizing an input data stream with an output data stream in a video processor. The method includes receiving an input data stream and receiving an output data stream, wherein the input data stream and the output data stream each comprise a plurality of pixels. The method further includes sequentially storing pixels of the input data stream using an input buffer and sequentially storing pixels of the output data stream using an output buffer. Timing information is determined by examining the input data stream and the output data stream. A synchronization adjustment is applied to the input buffer and the output buffer in accordance with the timing information. Pixels are output from the input buffer and the output buffer to produce a synchronized mixed video output stream. | 06-04-2009 |

20130258725 | Systems and Methods for Balancing UPS Source Currents During Unbalanced Load Transient Conditions - Systems and methods for balancing current from an AC source. The method includes determining a difference between a DC voltage output by a rectifier in an uninterruptible power supply (UPS) to a DC reference voltage. The method also includes determining an error between the DC voltage and the DC reference voltage based at least in part on the difference. After determining the error, the method includes filtering a second order harmonic from the error thereby generating a filtered error. The method may then include determining one or more switching signals for one or more switching components in the rectifier based at least in part on the filtered error and sending the switching signals to the rectifier. | 10-03-2013 |
20140036555 | Intelligent Level Transition Systems and Methods for Transformerless Uninterruptible Power Supply - Systems and methods are provided for controlling an uninterruptible power supply (UPS) to transition between three- or higher-level operation and two-level operation in a neutral-point-clamped (NPC) inverter. In an example, a UPS system includes an NPC inverter and a controller. The NPC inverter may supply power to a load. The controller may control the inverter to operate in a three-level mode or higher when the load is substantially balanced and to operate in a two-level mode when the load is substantially unbalanced. | 02-06-2014 |
