    Abstract: A process for forming a unidirectionally oriented fiber structure formed of high tenacity fibers. A plurality of yarns of high tenacity fibers are supplied, with the yarns being unidirectionally oriented. The yarns are coated with a liquid having a viscosity of about 5 to about 600 centipoises and tension is applied to the yarns. The yarns are passed through a fiber spreading device and the yarns are dried. The yarns are reduced in thickness and increased in width after passing through the fiber spreading device, with the fibers forming the yarns being spread apart, thus providing a relatively thin unidirectionally oriented fiber structure.

  • Patent number: 6149982
    Abstract: Plasma assisted polymerization and deposition of a very thin inner surface coating in a plastic or metal container without an undesirable increase in container surface temperature is provided to change the surface properties of the internal plastic surface of a container by reaction of the surface with a reactive gas which has been energized to produce a plasma or the surface is activated by a plasma of reactive gas so that it becomes receptive to a further surface reaction.

  • Patent number: 6117480
    Abstract: Medical cannulas are typically provided with a silicone coating to improve incision performance. In order to produce a thin, continuous and even coating layer, silicone oil is provided at one side of an elastic foil and the foil is penetrated by the uncoated cannula from an opposite side. During this operation the cannula is wetted by the silicone oil. During withdrawal of the cannula from the foil, excess silicone oil is removed from the cannula and an even, particle-free thin coating which has no bulge- or bead-forming tendency during incision is obtained. Subsequently, the silicone coating is dried.

  • Patent number: 6066367
    Abstract: The present invention provides a method for forming a pattern on a synthetic wood board to form, on a surface of the synthetic wood board, a pattern such as wooden grain and the like which is close to natural wood, to enhance the reality of woody like appearance. The synthetic wood board is formed by mixing 35-80 wt % of thermoplastic resin material and 20-65 wt %. By a first grinding process, the synthetic wood board is formed at its entire surface of at least one side thereof with a large number of wound stripes in one direction. By a colorant coating process, a colorant is coated on the surface on which said wound stripes are formed, the colorant impregnates in wood meal on the surface to generate blur. And some colorant remain in recess portion of the wound stripes to form recess pigment layer.

  • Patent number: 5965207
    Abstract: A method of applying a smooth thin waterproof coating on engineered particleboards including oriented strand boards, thereby permitting the use of such boards for applications wherein the boards are exposed to moisture, including, for example, foundation forms, roof sheathing, basement walls, etc. The method of this invention includes applying a thin liquid cementitious coating on a surface of an engineered particleboard having a moisture content preferably less than three percent, wherein the cementitious coating fills the interstices between the particles and coats the surface. The cementitious coating is then dried and the surface is abraded to receive a thin liquid curable polyurethane coating over the cementitious coating. Finally, the exposed surface of the polyurethane coating is heated to remove surface imperfections and cure the polyurethane coating.

  • Patent number: 5925406
    Abstract: A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5.times.10.sup.5 cm.sup.3 /100 square inches/day to about 2.times.10.sup.5 cm.sup.3 /100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate.

  • Patent number: 5750196
    Abstract: A die is utilized to cut chew toy bases from tire sidewalls extracted from used tires. The chew toy bases are initially soaked in a cleansing solution of bleach and a detergent, and are subsequently cleaned by scrubbing them with a brush and rinsing with water. The chew toy bases are placed on a drying rack, and are then soaked in a conditioning solution of a silicone-based rubber beautifier and a scenting and/or flavoring agent. The chew toy based are then polished and screened utilizing a metal detector to identify if there is any metal within the new toy bases. The chew toy bases are suitable for use as dog chew toys and, depending on the particular design of the chew toy bases, may be assembled to other chew toy bases to manufacture a composite dog chew toy.
