  • Patent number: 6576341
    Abstract: This invention relates to a process for purification of nanotube soot in a non-destructive and efficient method using a polymer having a coiling structure to extract nanotubes from their accompanying material without damage to their structure and with a high mass yield. Nanotube soot is added to a solvent which including a coiling polymer to form a solution. The solution is mixed with a nanotube composite suspension is formed with extraneous solid material such as amorphous carbon settling at the bottom of the solution. The nanotube composite suspension is decanted from the settled solid.

  • Patent number: 6506165
    Abstract: A device (1) for acquiring cell samples by aspiration into an evacuated container (3) comprising: a front hollow needle portion (7) to be inserted into the body from which a sample is to be taken; a rear hollow needle portion (5) for communication with the evacuated container; a conduit (11) connecting the front needle portion (7) to the rear needle portion (5); and a normally closed pinch valve mechanism (6) to open and close the conduit; The valve mechanism (6) is manually operable by one hand and controls the application of negative pressure in the front needle portion (7). The conduit may comprise a flexible tube and the valve mechanism (6) may comprise releasable means (8) to pinch the flexible tube in a pressure-tight manner. The valve mechanism (6) may comprise a spring-biased push-button (8) operable by one digit of a user's hand.

  • Patent number: 6419752
    Abstract: A structuring device (SD) for processing a surface of a substrate (SB), comprising a substrate chamber (VC) for mounting the substrate (SB) and a reaction chamber (GC) enabling a gas reaction at a given operating pressure. The reaction chamber (GC) has at least one gas inlet (GL) for a reaction gas and at least one injection outlet (JL) leading into the substrate chamber, while the substrate chamber (VC) is provided with a pumping system (PP) for maintaining a vacuum within the substrate chamber at a pressure not above the operating pressure of the gas reaction in the reaction chamber (GC). The injection outlet (JL) is provided with at least one injection pipe ending into an injection opening of given width, the injection pipe having a length not smaller than the width of the injection opening, the injection pipe forming the gas particles originating from the gas reaction into a gas jet streaming out of the injection opening.

  • Patent number: 6194163
    Abstract: The present invention is drawn to a method for the quantitative determination of human acute phase serum amyloid A protein (A-SAA) comprising contacting a sample of a biological fluid with antibody specific for A-SAA, the sample being reacted with an organic solvent prior to or simultaneous with antibody contact. The organic solvent is suitably a C1 or C4 alcohol and the antibody can be used on the solid phase and as a component of the detection system of an enzyme linked immunosorbant assay. The method provides a sensitive and reliable measure of A-SAA and inflammatory status which can be used for the diagnosis and clinical management of both acute and chronic inflammatory conditions.

  • Patent number: 5478411
    Abstract: A process is provided for modifying the magnetic properties of an intermetallic compound comprising at least iron, or a combination of iron with at least one transition metal, and at least one rare earth element. The process comprises heating the intermetallic compound in a reaction gas containing at least one element of groups IIIA, IVA or VIA of the Periodic Table in the gaseous phase to interstitially incorporate the element or elements of these groups into the crystal lattice of the intermetallic compound. Novel magnetic materials showing easy uniaxial anisotropy, increased spontaneous magnetization and Curie temperatures are produced by the process.

  • Patent number: 4838706
    Abstract: A method and apparatus for thermal analysis of a solid or liquid sample which evolves or absorbs gas on heating or cooling, wherein the sample is heated or cooled in an enclosed space, the temperature of the sample and the pressure of the gas are continuously monitored by temperature and pressure sensors respectively, and measurements of sample temperature and gas pressure are input to a data processor which also controls the temperature change of the sample. The value of gas pressure as a function of sample temperature and the rate of change of this value with respect to sample temperature are calculated; these functions are characteristic of the sample or of a component of the sample under analysis.

  • Patent number: 4301411
    Abstract: An NMR test method is provided for determining the homogeneity of dispersion of a filler substance such as carbon black in an elastomer composition such as a rubber, either on an arbitrary scale or by reference to a standard dispersion of optimum homogeneity which is given the value 1.0 on a linear scale. The method involves measuring the intensity of the short component and the total intensity of the proton free induction decay, of a sample of the dispersion deriving the ratio P.sub.t of said intensities, and optionally deriving a second similar ratio P.sub.s from the standard dispersion to permit a value P.sub.t /P.sub.s on said linear scale to be derived.
