  • Patent number: 8076842
    Abstract: Multilayer polymer light-emitting diodes (PLEDs) are demonstrated using semiconducting polymers blended with organometallic emitters as the emissive layer and one or both of an electron transport layer and a hole transparent layer on the appropriate electron injection and hole injection sides of the emissive layer. The transport layers reduce energy potential gaps between the hole injection electrode and the emissive polymer and between the electron injection electrode and the emissive polymer. A solvent-processing based procedure for preparing these devices is also disclosed It uses nonpolar solvent-based solutions of emissive polymers to form the emissive layer and polar solvent-based solutions to form the transport layers to minimize etching and other undesirable interactions as the multiple layers are being laid down.

  • Patent number: 8075987
    Abstract: A molded article such as a floor tile is made from recycled carpet waste which includes a polyvinyl chloride component in the backing material and fiber component having a melting point above the melting point of polyvinyl chloride. A mixture of the recycled carpet material is shredded and additional polyvinyl chloride is fed to an extruder where the polyvinyl chloride is melted without melting the carpet fibers. The resulting mixture is discharged and molded, such as by injection molding, to form a molded product. The molded product includes a continuous matrix of polyvinyl chloride having recycled carpet fibers uniformly dispersed therein. The molded article contains about 45% to about 85% of polyvinyl chloride, about 5% to about 20% of recycled carpet fibers, up to about 5% of a plasticizer and up to about 5% of an ethylene copolymer by weight based on the total weight of the product.

  • Patent number: 8071191
    Abstract: The specification discloses a method for affixing a strip to an underlying web substrate. According to the method, a substrate web having at least one surface is provided and at least one strip is applied over at least a portion of the substrate surface such that at least a significant portion of an underside surface of the strip disposed adjacent the substrate surface is unbounded to the substrate. A polymer coating is extruded over both the substrate surface and the strip. The strip is thereby affixed to the substrate surface by the coating while the portion of the underside surface of the strip remains substantially unbounded to the substrate surface. At the same time, a substantial portion of an upper surface of the strip adjacent the polymer coating layer is bonded to the coating layer. Also disclosed are packaging materials formed from the reinforced substrate.

  • Patent number: 8012590
    Abstract: Glass coatings on metals including Ti, Ti6A14V and CrCo were prepared for use as implants. The composition of the glasses was tailored to match the thermal expansion of the substrate metal. By controlling the firing atmosphere, time, and temperature, it was possible to control the reactivity between the glass and the alloy and to fabricate coatings (25-150 ?m thick) with excellent adhesion to the substrate. The optimum firing temperatures ranged between 800 and 840° C. at times up to 1 min in air or 15 min in N2. The same basic technique was used to create multilayered coatings with concentration gradients of hydroxyapatite (HA) particles and SiO2.
