  • Patent number: 9881699
    Abstract: A method for fabricating a cellular tritium breeder component includes obtaining a reticulated carbon foam skeleton comprising a network of interconnected ligaments. The foam skeleton is then melt-infiltrated with a tritium breeder material, for example, lithium zirconate or lithium titanate. The foam skeleton is then removed to define a cellular breeder component having a network of interconnected tritium purge channels. In an embodiment the ligaments of the foam skeleton are enlarged by adding carbon using chemical vapor infiltration (CVI) prior to melt-infiltration. In an embodiment the foam skeleton is coated with a refractory material, for example, tungsten, prior to melt infiltration.

  • Patent number: 9676631
    Abstract: A process for producing reaction bonded silicon carbide (RBSC) from high purity, porous, essentially all-carbon preforms through contacting said preforms with silicon metal at room temperature, and subsequently heating to melt silicon metal and cause infiltration into said preform causing reaction to silicon carbide and leaving residual silicon, to result in a dense silicon carbide-silicon composite. The process offers the ability to produce RBSC with higher purity, higher strength, and lower cost as long as the carbonaceous preforms are of sufficient purity and pore size distribution to allow for uniform, crack-free bulk bodies to be fabricated.

  • Patent number: 8906284
    Abstract: A wrinkled adhesive surface is prepared by swelling a laterally confined elastomer layer with a polymerizable monomer composition. Swelling the elastomer layer spontaneously produces a wrinkled surface, and the wrinkles are then stabilized by polymerizing the polymerizable monomer composition. The stabilized wrinkled surfaces prepare by the method can exhibit substantially enhanced adhesion relative to smooth surfaces of the same material. The stabilized wrinkled surfaces can also exhibit adhesion that is repeatable through many cycles of contact with and separation from another surface. The adhesive characteristics of the stabilized wrinkled surfaces can be tailored by manipulating the size of the wrinkles.

    Abstract: Systems and methods for fabrication of composite shell elements and to the assembly of large scale structures comprising such composite shell elements are provided. The composite shell elements comprise two regions in which the resin is cured to different levels. As a consequence, the flexibility of the first region is greater than the flexibility of the second region. Since the first region defines a bending line, the composite shell element can be deformed along the bending line during assembly of the large scale structure. Thus, tolerances in fabrication of the composite shell elements may be compensated for in a time-efficient manner without the need for applying a shimming process.

  • Patent number: 8318059
    Abstract: The present invention provides a method for producing a medical device, preferably an ophthalmic device, more preferably a contact lens, made of a stabilized poly(oxyalkylene)-containing polymeric material. The method of the invention comprises the steps of: curing, in a mold, a composition comprising (a) a prepolymer having at least one poly(oxyalkylene) unit, (b) a biocompatible organic multi-acid or biocompatible salt thereof in an amount sufficient to improve the stability of the poly(oxyalkylene)-containing polymer made from the composition, (c) optionally a photoinitiator or a thermal initiator, and (d) optionally one or more vinylic monomers, to form the medical device being less susceptible to oxidative degradation; and removing the medical device from the mold.

  • Patent number: 8303875
    Abstract: A method for producing a vinylidene fluoride resin film having excellent transparency, weather resistance, chemical resistance, break resistance and formability is provided. The film is shaped by sandwiching a vinylidene fluoride resin in a molten state between rollers or metal belts so as to let them cool down, thus realizing polyvinylidene fluoride with a fine average spherocrystal diameter. Thus, the vinylidene fluoride resin film having the above-stated properties can be obtained.

  • Patent number: 8298460
    Abstract: The invention relates to a method for granulating and crystallizing thermoplastic polymers, the granules being contained in a liquid after granulation of a polymer melt and the granules being nucleated in the liquid once the pressure of the liquid is increased and the temperature of the liquid is increased, and the granules being crystallized in the liquid once the pressure of the liquid is again increased and the temperature of the liquid is again increased. According to the invention, the granules are removed from the liquid once the pressure and the temperature of the liquid containing the granules have been reduced.
