20140255611 | PROCESS FOR THE ANTICORROSION TREATMENT OF A SOLID METAL SUBSTRATE AND TREATED SOLID METAL SUBSTRATE CAPABLE OF BEING OBTAINED BY SUCH A PROCESS - An anticorrosion treatment process in which applied to an oxidizable surface of a solid metal substrate is a liquid solution, referred to as treatment solution, including: at least one alkoxysilane, and at least one cerium (Ce) cation; in a liquid aqueous-alcoholic composition, the treatment solution being suitable for being able to form, at the surface of the solid metal substrate, a hybrid matrix by hydrolysis/condensation of each alkoxysilane(s) and of each cerium (Ce) cation; the treatment solution having a molar ratio (Si/Ce) of silicon element of the alkoxysilane(s) with respect to the cerium (Ce) cation(s) of between 50 and 500; characterized in that the cerium (Ce) cation(s) has(have) a concentration between 0.005 mol/L and 0.015 mol/L in the treatment solution. | 09-11-2014 |
20150020925 | METHOD FOR THE SURFACE TREATMENT OF PARTS MADE OF AN ALUMINUM OR MAGNESIUM ALLOY - A method for surface treatment of a part made of aluminum, magnesium, or one of the alloys thereof, to protect the part from corrosion. The method comprises consecutively immersing the part in a first aqueous bath containing a corrosion-inhibiting metal salt and an oxidizing compound, and a second aqueous bath containing an oxidizing compound and a corrosion-inhibiting rare-earth salt. The method can be carried out for the chemical conversion of aluminum or the alloys thereof, and of magnesium or the alloys thereof, on parts that have not been previously treated, or after anodizing the part to seal the anodic layer. | 01-22-2015 |

20140349330 | METHODS FOR AGGREGATION AND DIFFERENTIATION OF MAGNETIZED STEM CELLS - The invention relates to a process which enables optimal aggregation of cells, typically of stem cells, promoting the organisation thereof and advantageously the differentiation thereof, in particular in the context of the formation of a tissue substitute. This process comprises exposing pretreated cells to a magnetic field and makes it possible to obtain large cell aggregates, even prepared in the absence of support matrix and/or of growth factor. The invention also relates to the cell aggregates that can be obtained using such a process and also to the uses thereof as tissue initiators with a view to obtaining a tissue structure of interest in vitro, ex vivo or in vivo. Moreover, it relates to the resulting tissue structures and to the uses thereof in research or in therapy as tissue substitutes. The present application also provides a method which advantageously makes it possible to monitor the development of the tissue of interest in vivo. | 11-27-2014 |

20130326861 | ATTACHMENT OF INSULATING PANELS ONTO A SUPPORTING WALL IN A REPEATING PATTERN - A sealed and insulating tank, notably for liquefied natural gas, includes, a supporting wall with anchor members disposed in a repeated pattern, a sealing barrier in contact with a product contained in the tank and a thermal insulation barrier disposed between the sealing barrier and the supporting wall, the thermal insulation barrier including a plurality of insulating panels disposed in the repeated pattern, each insulating panel being fixed to the supporting wall by an adhesive disposed on a lower surface of the insulating panel and one or more anchor members of the supporting wall each cooperating with a hole passing through the insulating panel. The number of anchor members per insulating panel is in the range 1 to 6, preferably 2 to 3. A method of fixing insulating panels employs a clamping tool. | 12-12-2013 |
