  • Patent number: 8865041
    Abstract: Process for extrusion of polymer by feeding a polymer feedstock to the feed port of an extruder having (i) two or more barrel sections arranged sequentially from (a) an upstream feed barrel section to which polymer feedstock to be extruded is fed, the upstream feed barrel section containing two screws each having a diameter of X, to (b) a downstream barrel section from which melted polymer is passed to a die and extruded, and (ii) a feed port for feeding polymer feedstock to be extruded into the extruder at its upstream end. The polymer feedstock is in the form of a powder, and the feed port area is a rectangular shape with width limited by the width of the upstream feed barrel section to 2*X and with a length greater than 2.5*X. The total area of the feed ports through which polymer feedstock is introduced is greater than 5*X2.

  • Patent number: 8845841
    Abstract: In a molding material installation method, an adhesive is separated into an upper side and a lower side from an application nozzle. The adhesive that has been separated on the lower side is applied to the surface of a multilayer glass panel. The adhesive that has been separated on the upper side is applied to a bottom surface of a glazing gasket molding material. The adhesive that has been separated on the upper side is placed on the adhesive that has been applied to the surface of the multilayer glass panel so that the glazing gasket molding material and the adhesive that has been separated on the upper side are applied to the adhesive that has been applied to the surface of the multilayer glass panel.

  • Publication number: 20140186477
    Abstract: A method an apparatus for reclaiming face fibers and polypropylene and/or polyvinyl chloride backing material from rolls and pieces of post-consumer carpet. The system includes a separator for separating the face fibers from the backing and for separating latex and carbon calcium powder from polypropylene backing. An extruder is provided for extruding the face fibers separated from the backing into extrusions, and a pelletizer pelletizes the extrusions. A roller opener opens the polypropylene backing into fibrous portions and also cleans such fibrous portions. Alternately, a granulator can be provided that chops and grinds the polypropylene or PVC backing into fragments after the separation of the face fibers from the backing. A heat source heats the PVC fragments, and also the polypropylene fragments (thereby separating the latex therefrom), and ultimately melts such fragments. Reclaimed fibers can be pelletized, made into extrusions, used in non-woven products and in other manners.

  • Patent number: 8733271
    Abstract: Disclosed is a method and apparatus for continuous coating with a rotational die in which coating materials flow in a radial direction. The linear speed of a substrate in need of coating is identical to the tangential speed of the surface of the rotational die so that the coating material, which flows in a radial direction of the rotational die, flows onto the substrate perpendicularly. Therefore, the ingredients of coating materials overlap one another (or stand vertically as a layer), and the vertical sequence of the coating material is ensured. This method and apparatus can be used to make organic electronic devices, organic light-emitting diodes and organic photovoltaic devices. Particularly, this method and apparatus can be used in bulk-hetero-junction of mixed coating of P-type and N-type semiconductors.

  • Publication number: 20140116295
    Abstract: Fresh concrete is treated with carbon dioxide prior to delivery to a product mold for forming concrete products. Carbon dioxide gas is directed through a manifold, which may be coupled to a feedbox or a hopper, upstream from the product mold. Treating the fresh concrete with the carbon dioxide gas while it is in a loose state prior to placement in the product mold may generally promote uniform and enhanced carbon dioxide uptake.
