  • Patent number: 9023259
    Abstract: A method for processing feed material to produce dense and spheroidal products is described. The feed material is comprised of powder particles from the spray-drying technique or solution precursor droplets from ceramic or metallic materials. The feed material is processed using plasma generated from a microwave. The microwave plasma torch employed is capable of generating laminar flow during processing which allows for the production of spheroidal particles with a homogenous materials distribution. This results in products having improved thermal properties, improved corrosion and wear resistance and a higher tolerance to interface stresses.

  • Patent number: 8791186
    Abstract: A method of determining that a thermoplastic was insufficiently dried before forming into a molded plastic part. The method comprises preparing a mixture of a thermoplastic polymer and an off-gassing compound, wherein the off-gassing compound is selected to release all water of hydration in response to target drying conditions specified for the thermoplastic polymer. The mixture is dried at actual drying conditions, and then heated to reduce the viscosity of the thermoplastic polymer and allow the mixture to flow. The mixture is then made to flow into a mold to form a plastic part at a molding temperature, wherein the molding temperature will cause any remaining water of hydration in the off-gas sing compound to off-gas and form surface irregularities in the plastic part. Non-limiting examples of the off-gassing compound include hydrated metal halides and ionic hydrates.

The multi-layer film structure may include a core layer comprising a thermoplastic polymer and essentially no migratory slip agents; a functional layer on a first side of the core layer, wherein the functional layer is a printable layer or a laminatable layer; and a heat sealable skin layer on a second side of the core layer, the heat sealable skin layer comprising a thermoplastic polymer and a slip system. The multi-layer film structure is prepared without any migratory slip additives. Without migratory slip additives, the multi-layer film structure exhibits excellent machinability on typical packaging equipment.

  • Publication number: 20090155530
    Abstract: Methods for surface modification of wood-fiber reinforced thermoplastic composites (WPCs) for improving surface adhesion of a water-based acrylic coating and composites having such surface properties are disclosed herein. In one embodiment, the surface of WPC formulations can be modified using one or more surface treatments including chromic acid treatment, oxygen plasma treatment, Benzophenone/UV treatment, and flame treatment. In another embodiment, WPC material can be sequentially treated with chromic acid and oxygen plasma to roughen the WPC material surface and increase the WPC surface wettability with polar liquids. In some embodiments, an acrylic coating peel load increased approximately 64% to approximately 170% following surface modification.

  • Publication number: 20090130350
    Abstract: In the present invention, a manufacturing process is provided in which a complete multi-component synthetic closure is achieved which incorporates printed indicia formed thereon, in a continuous, in-line manufacturing operation. In the preferred embodiment of the present invention, the core member of the synthetic closure is formed by a continuous extrusion process which enables the core to be manufactured as an elongated, continuous length of material. As the continuous elongated length of extruded material forming the central core is advanced from the extruder towards an outer skin forming station, the central core passes through a printing station for forming any desired indica on the outer surface of central core prior to the application of the outer skin layer.

  • Publication number: 20080244898
    Abstract: A method for forming a circuit board is provided. The method includes forming a circuit board substrate (112) from a circuit board material. The method also includes positioning the circuit board substrate on a rigid structure (114) having a three dimensional contoured surface (300). The method further includes applying heat and applying pressure to the circuit board substrate to at least partially conform the circuit board substrate to the three dimensional contoured surface. If the circuit board substrate (112) is a clad circuit board substrate, then a circuit pattern is formed on the circuit board substrate prior to the steps of applying heat and applying pressure. However, if the circuit board substrate (112) is an unclad circuit board substrate, then a circuit pattern is disposed on the circuit board substrate after the steps of applying heat and applying pressure.

    Abstract: A method for fabricating tapered optical fibers is provided. The method includes applying thermal energy at a location defined along an elongated length (114, 116, 118) of an optical fiber (112). The method also includes varying the location in a first direction of travel at a predetermined rate along the elongated length of the optical fiber while applying a tension to the optical fiber. The method further includes removing the tension when the location is outside a first portion (116) of the elongated length. According to an aspect of the invention, the method includes transitioning from the first direction of travel to a second direction of travel opposed to the first direction of travel when the location is within a second portion (114) of the optical fiber. The method further includes transitioning from the second direction of travel to the first direction of travel when the location is within a third portion (118) of the optical fiber.
