  • Patent number: 7399438
    Abstract: A method to produce thin-layer lignocellulosic composites, such as wood-based doorskins, that exhibit substantial resistance to moisture is disclosed. In an embodiment, the method includes the steps of forming a mixture including a refined lignocellulosic fiber, wax, and an organic isocyanate resin. The mixture is initially pressed to form a loose mat. Subsequently, the mat is pressed between two dies at an elevated temperature and pressure to further reduce the thickness of the mat and to promote the interaction of the resin with the lignocellulosic fibers. In an embodiment, a release agent is included as part of the fiber mixture, or sprayed onto the surface of the mat. The thin-layer lignocellulosic composites of the present invention exhibit strong surface strength, high adhesiveness, and a 50% reduction in linear expansion and thickness swelling upon exposure to a high moisture environment as compared to thin-layer composites that do not include the isocyanate resin.

  • Patent number: 7354539
    Abstract: The process includes a weighing operation of a mass of material a glue is to be spread on, and thereafter a spraying operation of glue, variably mixed with steam, so that the glue is spread on the wood chips proportionately to a weight of the wood chips. The gluing process is completed in a resin bonder machine comprising a cylindrical body in which two different-diameter and oppositely-pitched helices are rotated to mix the glue and chips. Both the body and the helices are cooled in order to prevent adhesion of glued material thereon.

  • Patent number: 7344671
    Abstract: The invention is specially directed towards intermittent motion packaging machines where the packages are momentarily immobilized at a forming station for the time duration of the package sealing and cutting. The polymeric sheets or films are sealed and cut after being exposed to a laser beam in a controlled and optimized manner. The laser beam is shaped with appropriate optical elements to provide a desired intensity profile in the section of the films to be sealed or sealed and cut. With this method, a package can be sealed and cut simultaneously in one exposure step. An optical clamp holds the films together while they are being sealed by the laser. The optical clamp can reflect back to the films, partially or totally, the laser beam intensity that has not been previously absorbed. The optical clamp further allows to monitor the sealing and cutting process while the process is being performed.

  • Patent number: 7338628
    Abstract: An improved method of forming fiber-reinforced plastic shells for bathtubs utilizes a fiber mat placed on a rear surface of a plastic shell. The fiber mat is infused with a resin, and is then cured. The mat and resin are preferably received within a vacuum chamber as the resin is infused. Further, the plastic shell is preferably supported on a fluidized bed during this process. The present invention eliminates the need for detailed air handling as is now required to handle impurities in the industrial air around the process of forming the bathtub shell.

  • Patent number: 7332111
    Abstract: The present invention provides methods and devices for producing particles with an average diameter less than about 15 ?m using the precipitation with compressed fluid-antisolvent (PCA) process and the carbon-dioxide assisted nebulization with a bubble dryer (CAN-BD) process. In the methods and nozzles of the invention, at least one jet of supercritical or near-supercritical fluid and at least one jet of solution interact to mix the supercritical or near-supercritical fluid and the solution within a chamber. The solution contains at least one solvent and at least one solute. At least one of the jets is a swirling jet. To form particles, the solvent and supercritical or near-supercritical fluid are then injected into a PCA or a CAN-BD process chamber. The degree of mixing depends in part on the power input into the mixing chamber. Power inputs of about 6.5×109 W/m3 enhance the degree of mixing and allow production of nanoscale particles with the PCA process.

  • Patent number: 7332110
    Abstract: An annular insert (4) is arranged in the optical component molding cavity of a mold to surround an outer periphery of raw material resin in a direction in which the resin is distributed in the cavity to limit the distribution of the raw material resin and define an outer profile of a lens (L). With this arrangement, it is only necessary to provide raw material resin only by a quantity equal to the volume of the region surrounded by the molding surfaces of upper and lower mold inserts (14, 24) and the inner peripheral edge of the annular insert (4) of the mold, so that the required volume of the raw material resin can be reduced. Since the pressure is preserved at the outer periphery of the distributed resin by the presence of the annular insert (4), the residual strain of the resin is minimized to prevent generation of sink mark, thereby providing excellent optical characteristics on the lens (L).
