    Abstract: A method for producing pharmaceutical products from a melt material, wherein the melt material emerges from nozzles in a perforated plate, and is then granulated. A motor-driven cutter arrangement having at least one blade is opposite the perforated plate so that it cuts pellets emerging from nozzles in the perforated plate. A gaseous coolant flows through a housing which adjoins the perforated plate and encloses the at least one blade. The pellets of the melt material are then solidified in the coolant. Coolant is introduced from a separate inlet chamber that circumferentially encloses the housing in the area of rotation and from an inlet nozzle arrangement extending circumferentially between the inlet chamber and the housing. Coolant is introduced circumferentially from all sides essentially radially inward. A substantially centripetal flow of the coolant is produced in the area of rotation, and the coolant and pellets are conveyed to an outlet.

  • Patent number: 8524139
    Abstract: An improved method for laser processing that prevents material redeposition during laser ablation but allows material to be removed at a high rate. In a preferred embodiment, laser ablation is performed in a chamber filled with high pressure precursor (etchant) gas so that sample particles ejected during laser ablation will react with the precursor gas in the gas atmosphere of the sample chamber. When the ejected particles collide with precursor gas particles, the precursor is dissociated, forming a reactive component that binds the ablated material. In turn, the reaction between the reactive dissociation by-product and the ablated material forms a new, volatile compound that can be pumped away in a gaseous state rather than redepositing onto the sample.

  • Publication number: 20080113106
    Abstract: Provided is a surface modification process in which the mixture molar ratio of air/hydrocarbon gas in a fuel gas including a reforming agent modifying compound containing a silane molecule silicon atom, titanium atom or aluminum atom, air and a hydrocarbon gas is set to a value in valu within a predetermined range, whereby a predetermined surface modification effect can be stably obtained for a solid material, regardless of differences of boiling points of reforming agent modifying compounds, environmental conditions of the surroundings, and the like. For this end, a flame produced from of the fuel gas, in which the mixture molar ratio of air/hydrocarbon gas is adjusted to 23 or more, together with a predetermined reforming agent modifying compound, is blown against toward the surface of a solid material by means of a surface modification apparatus.

  • Patent number: 7303707
    Abstract: A method of processing lignocellulosic material includes the steps of comminuting the material to a size that it can be processed in a hydrothermal pressure vessel, drying the material in moving air to obtain a specific moisture content, packing the material into the vessel and subjecting the material within the vessel to steam under pressure, decompressing the vessel to return the temperature and pressure to ambient and drying the product to specific moisture content; the product so formed can be used for injection moulding or to form panel boards and the like.

  • Patent number: 7285617
    Abstract: Processes are disclosed for oxygen-tailoring polyethylene blow molding resin. Polyethylene resin is conveyed through a feed zone, a melt-mixing zone and a melt zone, wherein the temperature of the polyethylene resin is from about 216° C. to about 260° C. in the melt zone. The resin is contacted with oxygen in an amount of at least about 20 parts by weight oxygen per million parts by weight resin. The oxygen-treated resin can be used to make polyethylene blow molded articles having improved melt strength, processability, and die swell.

  • Publication number: 20070176314
    Abstract: A method of manufacturing a display device according to an exemplary embodiment of the present invention includes applying an organic material onto a substrate that is mounted on a supporting plate, contacting a surface of the mold on which a predetermined pattern is formed with the organic material, disposing the supporting plate an at angle, and pressing the mold while rotating the pressure roller. Therefore, the apparatus and method for manufacturing a display device according to the embodiment of the present invention have advantages that bubbles generated from the organic material are removed by using an inclined supporting plate and rotating the pressure roller in a direction opposite to the moving direction, thereby suppressing the formation of the bubbles.

  • Patent number: 7220375
    Abstract: A method and a multi-platen press for the practice of the process for the manufacture of wood material boards, especially OSB boards, in which an endless mat is formed from a wood chip and binding agent mixture. The mat is introduced between the heated press platens of a multi-platen press, the press platens have steam openings directed at the mat and by steam and contact heat from press platens they are heated, pressed and cured into wood material boards. The mat, formed from a wood chip and phenolic resin mixture, is introduced into the level(s) of a single-stage or multi-stage press and deposited therein. After a light precompression, the introduction of a small amount of steam with a low steam temperature takes place through the press platens only in the cover layers of the mat. The mat is quickly compressed and cured to the end thickness of the board.

  • Patent number: 7172713
    Abstract: A solution casting process for producing cellulose triacetate (TAC) film is provided. Bead of dope, which includes cellulose triacetate and solvent, is cast on to a rotating supporting drum, to form self-supporting cast film. The self-supporting cast film is stripped from the supporting drum. The self-supporting cast film is dried while the self-supporting cast film being stripped is fed by feed rollers, to form the cellulose triacetate film. A surface temperature of the feed rollers is set equal to or lower than 0° C. The self-supporting cast film upon being stripped has modulus of longitudinal elasticity equal to or more than 450,000 Pa.
