| 20090114592 | METHOD FOR PURIFYING WASTE WATER WITH ADDED OXIDIZING AGENT - The invention concerns a method for purifying wastewater loaded with organic matter, said method including: a step of contacting wastewater with a biological culture containing a purifying biomass and a step of separating performed by filtration through organic or inorganic membranes. The invention is characterized in that at least part of the biological culture is subjected to an oxidative stress step enabling a liquor to be obtained by the action of at least one oxidizing agent used in small amount so as to preserve the biological activity of the purifying biomass while modifying the microbial floc to make it denser. | 05-07-2009 |
| 20100032373 | METHOD FOR THE OPTIMISED MANAGEMENT OF A MEMBRANE FILTRATION UNIT AND EQUIPMENT FOR REALISING THE SAME - The invention relates to a method for the optimised management of a membrane filtration unit based on membrane micro-coagulation, that comprises at least one measurement of the effluent temperature ( | 02-11-2010 |
| 20100282679 | ADVANCED CONTROL METHOD FOR A MEMBRANE FILTRATION UNIT, AND DEVICE FOR IMPLEMENTING THE METHOD - Advanced control method for a membrane filtration unit, applied to the treatment of an effluent, employing microcoagulation on a membrane, which consists in injecting, upstream of the membrane, a dose of coagulation reactant(s) 30 to 80 times below the dose (X) making the zeta potential of the effluent zero, in which method: quantities defining the quality of the effluent to be treated and quantities defining the state of membrane clogging are measured as input variables; the operating point of the microcoagulation process is located on the basis of the results of the above measurements; thresholds for the input variables are determined, the microcoagulation having to be initiated when said thresholds are violated; and the coagulation reactant(s) is(are) injected depending on the results of the measurements and on the comparison of the input variables with the respective thresholds. | 11-11-2010 |
| 20120111806 | PULSED SLUDGE BED SETTLING METHOD AND DEVICE - The invention relates to a pulsed sludge bed settling method for treating all types of liquid, in particular water, and which uses at least one powder or grain reactant, according to which: the liquid and the reactant(s) for the treatment are contained in a tank ( | 05-10-2012 |

| 20090125116 | HINGED JOINT SYSTEM - Methods, systems, and devices for replacement of a joint with a prosthetic system that replicates the natural kinematics of the joint is disclosed. A prosthetic system according to one embodiment includes a tibial component having a tibial plateau and a tibial stem portion, the tibial plateau having a top side and a bottom side, a tibial insert, with a bearing surface adapted to be positioned on the top side of the tibial plateau, a femoral component having a base portion and a central housing, the femoral component having an axis of extension-flexion rotation, the base portion having a pair of condyles, a mechanical linkage component linking the tibial component with the femoral component and with the tibial insert in between the tibial component and the femoral component, so that there is a center of contact between the condyles and the bearing surface, the mechanical linkage component adapted to allow the center of contact to move posteriorly during flexion, provide for the movement of the axis of extension-flexion rotation in the superior-inferior direction, and allow rotation of the tibial component, the bearing surface, and the femoral component about a superior-inferior axis in order to provide and control the natural kinematics of the knee joint. | 05-14-2009 |

| 20110025090 | RIGIDIFIED WINDOW SYSTEM - A rigidified window system includes a window and at least one supporting brace. The at least one supporting brace is bonded to the surface of the window using an adhesive offering a predetermined elasticity to the bond. Moreover, the quantity, shape, width, length and height and material used to manufacture the at least one supporting brace are selected in order to allow a certain flexibility of said window and the at least one supporting brace. The elasticity of the bond and the flexibility of the window and the at least one supporting brace provide absorption of the forces created by an impact, the absorption being shared between the window, the bond and the at least one supporting brace. | 02-03-2011 |
