    摘要: An apparatus and method for testing the glucose level in a blood sample is provided. The method includes the step of initially filtering a sample of blood to be tested. A beam of light is provided and split into a pair of beams by a beam splitter. The pair of beams travel along generally parallel paths. One path contains a cell of a known optical pathlength and additionally a compensator. The other path has a cell containing the filtered blood sample to be tested. The pair of beams are then recombined by a mirror and a fringe pattern is detected at a detector. From the fringe pattern, the refractive index of the blood sample can be calculated. The refractive index is easily converted to a specific glucose concentration. Alternatively, the original fringe pattern can be restored by changing the effect of the compensator. The refractive index can then be found from the required compensation.

    摘要: Particles of a magnetic material coated with a hydrophobic surfactant are dispersed in an organic solvent extractant to produce a magnetic solvent extractant which can be used in solvent extraction processes. Phase separation of an organic phase, carrying the component to be separated, from the aqueous phase can be accelerated by applying a magnetic field to the organic phase. After removal of the organic phase, a magnetic field can be applied to the aqueous phase to remove any residual organic phase and thereby enhance the degree of separation.

    摘要: Flakeboard or particle board panels and other composite articles made from wood flakes or other particulate lignocellulosic materials having a relatively high internal bond and improved resistance to moisture are made from flakes or particles which have a moisture content of at least 15%. A catalyst capable of accelerating the reaction between the flakes or particles, the binder and water is applied to the flakes or particles prior to the addition of a moisture-tolerant particle board binder, such as an organic polyisocyanate. A mat of the resulting furnish is compression shaped under pressure and at a temperature less than 250.degree. F. for a time period sufficient to form a composite article of the desired shape and/or dimensions.

    摘要: Particles of a nonmagnetic material are rendered magnetic by contacting their surfaces with a magnetizing reagent comprising water containing particles of a magnetic material, each of which has a two layer surfactant coating including an inner layer and an outer layer. The inner layer covers the magnetic particle and is a monomolecular layer of a first water soluble, organic, heteropolar surfactant containing at least 3 carbon atoms and having a functional group on one end which bonds with the magnetic particle. The outer layer coats the inner layer and is a monomolecular layer of a second water soluble, organic heteropolar surfactant containing at least three carbon atoms and having a hydrophobic end bonded to the hydrophobic end of the first surfactant and a functional group on the other end capable of bonding with the particles to be magnetized.

    摘要: Sulfide derivatives of catechins derived from condensed tannins have broad spectrum biocidal characteristics. Epicatechin-4-alkylsulfides and cupric complexes thereof containing up to 20, preferably 5 to 15, carbon atoms are particularly effective biocides against wood rotting fungi and gram-positive bacteria.Such sulfides are prepared by reacting condensed tannin, either in the form of a purified tannin extract or comminuted plant tissue, with an appropriate thiol under mild acidic conditions.

    摘要: Apparatus for forming a loosely felted mat of elongated wood flakes, the wood flakes being aligned in parallel relation and parallel to the longitudinal direction of the mat. The apparatus includes a former for depositing wood flakes on a support surface in a uniformly dispersed, loosely felted relation, and a plurality of vertically oriented baffles positioned below the former and in mutually parallel alignment. The baffles are reciprocated in the direction of the mat to cause flakes lying across the baffles to fall between the baffles and to be aligned with the longitudinal direction of the mat.

    摘要: An apparatus is provided for forming a continuous loosely felted mat of wood flakes, the wood flakes being elongated and being aligned in mutually parallel relation and parallel to the longitudinal axis of the mat. The apparatus includes a conveyor having an upper surface adapted to support a mat of wood flakes and formers for continuously depositing wood flakes on the conveyor as it moves under the former. Also included are continuous lengths of baffle material positioned between the formers and the conveyor, and oriented so as to define parallel adjacent vertical planes, the planes being parallel to the direction of movement of the upper surface. The lengths of baffle material are positioned in closely spaced side-by-side relation and move with the upper surface beneath the formers as the loosely felted mat is formed and are adapted to cause the flakes to become aligned and to be held in alignment during formation of the mat.
