20150101397 | METHOD FOR TESTING NON-UNIFORM LOADS IN PIPES - The present invention refers to a method wherein a test body is assembled in specific configurations to be submitted to testing in a conventional hydrostatic chamber. The method calls for assembling a test body that simulates cementing failures, the presence of stress anisotropy and a borehole of irregular geometry, by pressurizing said test body in a conventional hydrostatic chamber. The uniform forces are distributed circumferentially around a casing stream in a non-uniform way, simulating operating conditions that are as close as possible to reality, enabling an analysis of how the structure reacts in scenarios similar to actual conditions. | 04-16-2015 |

20100072261 | FRICTION STIR WELDING SPINDLE DOWNFORCE AND OTHER CONTROL TECHNIQUES, SYSTEMS AND METHODS - Friction stirred welding equipment, developed according to requirements of high reliability, robustness, precision and low cost, weld lap and butt joints in complex surfaces with fixed pin tool under controlled downforce. Exemplary equipment comprises a control force orbital spindle, wherein a coaxial sensor measures the downforce and simultaneously the axial electrical actuator corrects axial tool position along the welding, by a direct axial force system control, in order to maintain controlled downforce according to previously set parameters. The equipment sets up, monitors and controls the spindle rotation speed, welding speed, acceleration speed and downforce and can record in a database the downforce and tool welding position during the welding. The exemplary equipment may also comprise a laser system that scans the backing surface before welding and corrects original tool path, in order to provide an offset tool path and precision alarm system to get a safe welding, avoiding tool collision with the backing. | 03-25-2010 |

20110079339 | FRICTION STIR WELDING SPINDLE DOWNFORCE AND OTHER CONTROL TECHNIQUES, SYSTEMS AND METHODS - Friction stir welding equipment control force spindle for mounting in an orbital head housing uses a coaxial sensor to measure downforce. Simultaneously, an axial electrical actuator is controlled to dynamically correct the axial tool position during the welding, by a direct axial force system control, in order to maintain controlled downforce according to parameters previously set, based on numerical control. The equipment also sets up, monitors and controls spindle rotation speed, welding speed, acceleration speed and downforce using for example closed loop control functions. A laser system may scan the backing surface before welding and correct original tool path, in order to get an offset tool path. A precision alarm system may provide safe welding while preventing the tool from colliding with the backing surface. | 04-07-2011 |

20090241733 | PROCESS FOR THE INSTANTANEOUS CONTROL OF PRECIPITATION OF NICKEL AND COBALT PRESENT IN THE LEACH LIQUOR, BY ADJUSTING THE PH OF THE SOLUTION - The present invention concerns a process for the instantaneous control of the precipitation of nickel and cobalt present in a leach liquor by adjustment of the pH-value. Said leach liquor is obtained by pressurized acidic leaching of laterile ores and additionally contains aluminium, ferric and ferrous iron and chromium among others. The process comprises the following steps: precipitation of aluminium, ferric and ferrous iron, chromium etc. by increasing the pH- value by adding a suitable reagent such as lime and/or limestone, following precipitation of nickel and cobalt by further increasing the pH-value of the liquor, finally separating the precipitate from the low-content nickel and cobalt solution. The nickel and cobalt precipitate can be used for further refinement. In order to keep the process conditions constant, the steps of increasing the pH-value are controlled simultaneously. | 10-01-2009 |

20100013229 | HYBRID WAVE ENERGY PLANT FOR ELECTRICITY GENERATION - The innovation herein proposed describes a plant to produce electricity by the sea waves. The plant is designed to be installed on shore, near shore and offshore scenarios: on the coast line, in shallow waters and in deep waters. The plant is operated by action of the sea waves on a series of floaters (A). The resultant force on each floater (A) acts on a mechanical load amplifier (B) which moves two vertical high pressure piston pumps (C). These pumps (C) send pressurized fresh water to a hyperbaric system (E). The hyperbaric system (E) supplies an outflow water jet through a controlled valve that moves a conventional turbine (G). This turbine (G) connected to the electric generator (H) produce electricity. | 01-21-2010 |
