20130287053 | METHOD AND DEVICE FOR EMITTING A LASER BEAM IN A HOUSING - A device for emitting a laser beam comprises, in a housing, a laser-emitting component emitting a laser beam and mounted on a base, a heat-dissipating component, at least one collimating lens, and a lens mounting. The heat-dissipating component dissipates the heat produced by the laser of the laser-emitting component and secures the base of the laser-emitting component. The heat-dissipating component has a positioning mark and at least three holes for centering pins machined together with the positioning mark. The lens mounting secures the lens opposite the laser-emitting component and is positioned relative to the heat-dissipating component by at least three centering pins positioned in the holes of the heat-dissipating component. | 10-31-2013 |
20130230426 | DEVICE FOR COLD PLASMA STERILIZATION OF AN OBJECT, SUCH AS MEDICAL DEVICE, PARTICULARLY AN IMPLANT, AND METHOD OF USING THIS DEVICE - The cold plasma sterilization device for the sterilization of at least one object is placed in a container enclosing at least a gas or a gas mixture suitable for generating a cold plasma. The device includes a closed vessel in which a support for receiving the container is arranged. There is a device for subjecting the vessel to a secondary vacuum of the order of 10 | 09-05-2013 |
20130205871 | METHOD AND DEVICE FOR DETECTING TRACE AMOUNTS OF MANY GASES - The photoacoustic device for measuring the quantity of at least one gas. The Helmholtz-type esonant container comprises at least two tubes closed at their ends and linked together, close to each of their respective ends, by capillary tubes of diameter lower than the diameter of the parallel tubes. Each of the two radiant laser energy sources is physically separated and adapted to supply an excitation energy to the gas in the container at a different emission wavelength. The modulation means modulates the excitation energy supplied by each laser energy source with a modulation frequency corresponding to the acoustic resonance frequency of the container. At least one acoustoelectric transducer disposed on one of the tubes detects the produced acoustic signals produced and supplies an electric signal representative of the gas concentration in the container. | 08-15-2013 |
20120277383 | INCREASE IN THE TOUGHNESS OF A MATERIAL OBTAINED FROM A CURABLE COMPOSITION COMPRISING AT LEAST ONE VINYL ESTER MONOMER - A method increases the toughness of a material obtained by curing a composition that includes at least one vinyl ester monomer. The method includes the incorporation into the composition of a sulfonated polyaromatic thermoplastic polymer, which is achieved by dissolving the vinyl ester monomer and the thermoplastic polymer in a reactive diluent in which they are both soluble. The resulting curable composition includes at least one vinyl ester monomer, and very high toughness materials can be made from it. A curable composition can include at least one vinyl ester monomer, a sulfonated polyaromatic thermoplastic polymer and a N-vinyl lactam. The compositions can be used in the aeronautical, space, railway, nautical, automotive industries, arms and other industries. | 11-01-2012 |
20120022228 | PURIFICATION OF AMPHOTERIC PRODUCTS, OR OF PRODUCTS LIABLE TO BE CONVERTED INTO AMPHOTERIC PRODUCTS - A process for purifying at least one product from a substrate containing at least one product, includes subjecting the substrate to centrifugal partition chromatography in an ion exchange displacement mode to purify the at least one product from the substrate, the at least one product being an amphoteric product. | 01-26-2012 |
20090305311 | C4D/C4B STANDARD FOR QUANTITATIVE FLOW CYTOMETRY OF HUMORAL TRANSPLANT REJECTION - The invention concerns an internal standard used to quantitative analysis of the risk of humoral (i.e. vascular) transplant rejection. The internal standard consists of a stable composition of the C4d complement bound to a carrier consisting of erythrocytes or microparticles. The invention also concerns a method for analyzing in vitro the risk of humoral organ transplant rejection, which consists in determining the amount of component of C4d component fixed on the erythrocytes contained in a blood sample from a patient. | 12-10-2009 |
20090266169 | DEVICE AND METHOD FOR MONITORING THE VIBRATORY CONDITION OF A ROTATING MACHINE - This present invention concerns a device having a mechanical bearing formed by two coaxial rings, one fixed relative to the machine and the other rotating, between which at least one rolling element is moveably positioned, at least one non-conducting positioning means secured to the fixed bearing ring, the positioning means including at least one placement holder for at least one conducting element forming a first plate of a capacitor, at a distance from a conducting part of the rotating ring forming the second plate of the capacitor, and with the positioning means attached to at least one partitioning means, the partitioning means being used to create a space between the two plates, thus forming a dielectric insulating medium, and to act as a sealed enclosure for this insulating medium ( | 10-29-2009 |
20090216012 | USE OF CENTRIFUGAL PARTITION CHROMATOGRAPHY FOR PURIFYING GALANTHAMINE - The invention concerns the use of centrifugal partition chromatography in displacement mode for implementing a process for purifying galanthamine or its derivatives, from a starting composition, containing at least 20% of galanthamine or its derivatives. Said method comprises a step of centrifuging a combination of at least two solvents and said starting composition, for a time sufficient for purifying the galanthamine or its derivatives, said solvents being such that they form two non-miscible phases, namely an aqueous phase and an organic phase, the aqueous phase serving as mobile phase or stationary phase, the organic phase serving respectively as stationary phase or mobile phase. | 08-27-2009 |
20080293636 | Protein Constructs Designed for Targeting and Lysis of Cells - The invention relates to a protein construct, comprising (i) a targeting moiety that is capable of binding to a target cell, and (ii) an effector immunogenic moiety that is capable of triggering an existing, vaccine-induced or natural, immune response. The protein construct, that is preferably in the form of a heteromultimeric protein, is useful for redirecting an immune response that was pre-existing in a patient, toward an undesired target cell. | 11-27-2008 |
