  • Patent number: 10814380
    Abstract: Devices and methods are disclosed for the centrifugal casting of spheres, particularly solid and hollow spheres having a gradient internal density. Molten or self-hardening casting material is introduced into a hollow spherical mold and the mold made to rotate about two axes intersecting at the center of the mold. The resulting centrifugal forces cause the casting material to be evenly distributed about the inner surface of the mold. If a mixture of casting materials of different densities is used, the densest material will settle closer to the walls of the mold, while less dense materials will move closer to the center. The casting material is hardened and the resulting sphere is removed from the mold. One or more valves may be employed to transport fluent materials into and out of the mold. If gas is removed from a partially-filled mold prior to casting, the product will be a hollow sphere having an interior pressure less than ambient.

    Abstract: Method for casting a continuous cylindrical polymer stamp. The method includes depositing a first layer of a fluid polymer on the inside of a rotatable drum and rotating the drum for a selected time and at a selected angular velocity. The polymer is cured to produce a uniform datum surface. A second layer of polymer is deposited on the first layer in the drum and the drum is rotated until solvent in the polymer has evaporated thereby forming a stable layer. The polymer is selectively exposed and developed to create a desired pattern. Thereafter, a polymer precursor is deposited on the patterned second layer and the polymer precursor is allowed to cure while the drum is rotating to produce a cured stamp. The cured stamp is removed from the drum.

  • Patent number: 8852484
    Abstract: A bead-forming apparatus and method for its use are described. The bead-forming apparatus includes a base with a pair of legs extending from a top surface. First ends of the legs couple to respective eccentric elements. The eccentric elements removeably and rotatably couple to a platen. Second ends of the legs are rotatably and slideably mated with a gear train disposed within the base. The legs are slideably translatable into the base and the gear train maintains a rotational orientation of the legs and the eccentric elements coupled thereto. The platen is thus moveable through a circular path defined by the rotation of the eccentric elements and legs. As such, a plug of moldable material placed between the base and the platen and in contact with the platen, is formed into a double-cone shape by movement of the platen through the circular path.

    Abstract: Methods are provided for preparing polymer mixtures having low residual monomer content. The methods comprise mixing the at least two polymers in a solvent to form a polymeric mixture, the polymeric mixture comprising at least one residual monomer; and adding an antisolvent to the polymeric mixture so as to separate the at least two polymers from the polymeric mixture, where the residual monomer is soluble in the antisolvent. In some embodiments, methods are provided for preparing at least two polymers having low residual monomer content, the methods comprise adding an antisolvent to a mixture of at least two polymers dissolved in a solvent so as to precipitate the at least two polymers from the solvent and anti-solvent. The methods provided avoid steps in dry blending of polymers and produces polymer blends that have low residual monomer content.

  • Publication number: 20140265053
    Abstract: Polymeric blends having improved flame retardance properties and good ductility at low temperatures are disclosed. The blend is formed from (A) a photoactive additive that is a cross-linkable polycarbonate resin containing a photoactive group derived from a dihydroxybenzophenone; and (B) a polymer resin which is different from the photoactive additive. The additive can be a compound, oligomer, or polymer. When exposed to ultraviolet light, crosslinking will occur between the photoactive additive and the polymer resin, enhancing the chemical resistance and flame retardance while maintaining ductility.

  • Publication number: 20140228498
    Abstract: A thermoplastic compound is formed using a blend that includes one of processed fly ash, cinders and processed fly ash and cinders with a fractional melt having a melt flow index of less than 1 or a low melt resin with a melt flow index between 1 and about 3 or both, and a resin compatible with the fractional melt or low melt resin and having a melt flow index that is different from the melt flow index of the fractional melt or the low melt resin. Presence of the processed fly ash and cinders is believed to reduce cycle time for forming the thermoplastic compound into a plastic product from about 5 percent to about 30 percent merely because of the presence of the processed fly ash and cinders. Presence of the processed fly ash and/or cinders also permits the increased use of more fractional melt than conventionally attempted and also allows for use of thermoplastic regrind from recycling sources.

  • Patent number: 8790561
    Abstract: Various embodiments herein include utilities for generating embosser drums that are used to pre-format optical media such as optical tape with a pattern of nanostructures such as wobbled grooves. One utility includes generating a plurality of replicas from an embossing master and bonding the replicas together to form a bonded replica structure having a surface with the nanostructure pattern imprinted therein and a surface area that is approximately the same as an outer embossing surface of the embosser drum to be formed. Advantageously, a single, one-piece metallic shim can subsequently be generated, appropriately shaped and welded at a single seam to form the embosser drum outer embossing surface.
