  • Publication number: 20130341835
    Abstract: Substrate containers formed from improved compositions comprise a polymer and carbon nanotubes to provide enhanced characteristics. In some embodiments, the carbon fibers, e.g., nanotubes, can be mechanically blended or incorporated into the polymer, while in some embodiments carbon nanotubes also may be covalently bonded to the polymer to form corresponding covalent materials. In particular, the polymer can be covalently bonded to the side walls of the carbon nanotubes to form a composite with particularly desirable mechanical properties. The processing of the nanotubes can be facilitated by the dispersion of the nanotubes in an aqueous solution comprising a hydrophylic polymer, such as ethyl vinyl acetate. A dispersion of nanotubes can be combined with a polymer in an extrusion process to blend the materials under high shear, such as in an extruder.

  • Publication number: 20130337253
    Abstract: An injection molded body includes a fiber reinforced thermoplastic resin composition formed by combining fibrous filler with thermoplastic resin so that the weight average fiber length in the injection molded body is 300 ?m or more, and the injection molded body has a skin layer, a core layer and a skin layer in this order in the thickness direction. The thickness of the core layer, in which the primary orientation direction of the fibrous filler is 40° or less when the direction perpendicular to the flow direction of the resin composition at the time of injection molding is set at 0°, is 20% or less relatively to the thickness of the injection molded body.

  • Patent number: 8529820
    Abstract: Methods and apparatus adjustably control the repositioning of non-homogeneous fluid conditions across the stream of a laminar flowing fluid to a desirable circumferential position. The invention is particularly applicable to controlling non-homogeneous melt conditions at about the intersection of two flow channels in systems having hot or cold flow channels. Various mechanisms are provided that enable simple adjustments of a flow diverter within a fluid rotation device, making either static or dynamic adjustments, so that the degree of fluid flow repositioning in a runner system can be changed without the need for mold disassembly or retooling. Various forms of actuators effect adjustment and may be manually manipulated or manipulated through various powered devices.

  • Patent number: RE45027
    Abstract: A method and apparatus are provided for moulding an article by feeding molten plastics material into a metering cavity (16), feeding a predetermined quantity of the material from the metering cavity into a mould cavity via a transition passage (26) adjacent the mould cavity and urging the molten plastics material from the transition passage into the mould cavity with a working stroke of a packing piston (24), until the packing piston closes a port (28) defined between the transition passage and the mould cavity and a leading face (32) of the packing piston forms part of the peripheral wall of the mould. Less than ninety percent of the mould cavity is filled with the molten plastics material when the packing piston starts its working stroke and the packing piston starts its working stroke while molten plastics material is still being fed from the metering cavity.
