    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.

    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.

    Abstract: Systems and methods for molding shells for fluid-filled prosthetic implants, including spinning and rotating dip- or spray-mandrels during a devolatilization step to ensure an even covering. The mandrels may be spun during the dipping or spraying step, and/or afterward while a solvent evaporates until a gum state is formed. The techniques are particularly useful for forming hollow shells from silicone dispersions for soft implants, such as breast implants.

  • Patent number: 8771572
    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, bonding the replicas together to form a bonded replica structure having a surface with the nanostructure pattern imprinted therein, creating a replica of the bonded replica structure and electroforming a metallic layer onto the bonded replica structure replica to create a single, one piece, metallic shim which can be used to create a weld-less embosser drum.

  • Patent number: 8771580
    Abstract: The invention relates to a method for the production of plastic molded skins which are built up by consecutively melting multiple plastics onto each other. The surface of the forming tool is partially covered with a covering or mask during the melting of a first plastic powder and the first plastic powder is applied to the forming tool by a powder spray method. Thereafter, the covering or mask is removed from the surface of the forming tool and the second plastic powder is applied to the surface of the forming tool and to the first plastic powder by rotation sintering.

  • Patent number: 8721951
    Abstract: A method to form a multiple walled enclosure with low permeation properties and rugged impact resistance useful as a fuel tank or chemical container. The enclosure is made by rotomolding a first charge of thermosetting polymer into an outer layer, then rotomolding a charge of EVOH or other low permeation thermoplastic into a second layer, then rotomolding a second charge of thermosetting polymer into a third layer so that the low permeation thermoplastic layer is fully enclosed by layers of thermoset polymer. The preferred thermosetting polymer is crosslinkable polyethylene and the preferred low permeation thermoplastic is EVOH.
