Patent application number | Title | Published |
20130157052 | CONTINUOUS, HOLLOW POLYMER PRECURSORS AND CARBON FIBERS PRODUCED THEREFROM - The present invention relates to a continuous, multicellular, hollow carbon fiber wherein the fiber structure includes a substantially hollow fiber and multiple internal walls defining multiple integral internal hollow fibers such that the fiber structure comprises a honeycomb-like cross section. | 06-20-2013 |
20110111225 | Extruded Filament Having High Definition Cross-Sectional Indicia/Coding, Microscopic Tagging System Formed Therefrom and Method of Use Thereof for Anti-Counterfeiting of Product Authentication - An extruded filament is provided having a cross-sectional configuration which permits a cut transverse section of the filament to function as a high definition tagging material, the extruded filament having contained therein along the direction of the longitudinal axis (the axis of extrusion) of the filament a multitude of extruded strand portions, which may be the same or different from one another from the standpoint of composition, visual or forensic effect, and which strand portions provide a multitude of pixel-like portions within a cross-sectional portion of the filament, which multitude of pixel-like portions, when taken together, comprise at least one pre-selected degree of identification whereby the tagging material may be differentiated or identified based on at least one degree of identification. A cut fiber or microparticle formed from the filament may be used to authenticate a product when used in association with the product. | 05-12-2011 |
20110076771 | TISSUE FIBER SCAFFOLD AND METHOD FOR MAKING - The present disclosure relates to a fiber, a method of forming a fiber, a system for forming a fiber, and a method of engineering tissue from a fiber. The fiber includes an engineered geometric feature forming a non-Euclidian geometry. | 03-31-2011 |
20100291384 | FIBER HAVING NON-UNIFORM COMPOSITION AND METHOD FOR MAKING SAME - A fiber having a non-uniform composition is disclosed. The fiber includes a first domain having a first composition and a second domain having a second composition different from the first composition. The fiber includes an interphase region intermediate the first and second domains that includes a blend of the first and second compositions to provide a gradual transition from the first domain composition to the second domain composition. A method for making such fibers is also disclosed. | 11-18-2010 |
20100173105 | CONTINUOUS, HOLLOW POLYMER PRECURSORS AND CARBON FIBERS PRODUCED THEREFROM - The present invention relates to a continuous, multicellular, hollow carbon fiber wherein the fiber structure includes a substantially hollow fiber and multiple internal walls defining multiple integral internal hollow fibers such that the fiber structure comprises a honeycomb-like cross section. | 07-08-2010 |
20100078848 | SPINNERET AND METHOD OF SPINNING FIBER - Disclosed is a spinneret and a method of spinning. The spinneret includes a first pore configured for extruding a first component of a multi-component fiber, a second pore configured for extruding a second component of the multi-component fiber, and a thermal insulator positioned between the first pore and the second pore and configured for preventing heat from the first component from damaging the second component. The first component and the second component have incompatible thermal resistance. | 04-01-2010 |
20090258787 | Superconducting Wires and Cables and Methods for Producing Superconducting Wires and Cables - A superconductor structure is manufactured by forming a channel within a substrate along a surface of the substrate, depositing a material within the channel of the substrate, where the material includes one of a superconductor material and a precursor for a superconductor material, and thermally treating the substance within the channel of the substrate so as to form an elongated superconductor wire formed as a single, cohesive structure. The substrate can further include a plurality of channels with superconductor wires formed within the channels. In addition, a cable is formed including a bundle of individual superconductor wires arranged at different spatial positions with respect to each other. | 10-15-2009 |
