  • Publication number: 20050040277
    Abstract: The present invention includes a method of lining a core slot that includes the steps of unwinding a tube, separating a portion of the tube, inserting the tube into a core slot, and expanding the tube to line the core slot. The present invention also includes a continuous piece of helically-wound tubing that is wound on a spool along with an apparatus and method used for creating the spool of tubing. The method includes the steps of helically wrapping a web of material in an overlapping relationship to form a helically-wound tube, advancing the tube in a longitudinal direction of the tube and winding the tube onto a spool while at least a portion of the tube is being formed by the step of helically-wrapping. Method variations in which one or more of the aforementioned steps may be eliminated as appropriate, can be used for many other uses.

  • Publication number: 20040236655
    Abstract: Methods and systems for managing and analyzing multi-dimensional data are provided. Example embodiments provide a Meta-Object Data Management System “MODMS,” which enables users to arrange and to rearrange the hierarchical relationships of the data on an ad-hoc basis and allows the data to be analyzed using any set of attributes (dimensions) while the system is running. The MODMS represents heterogeneous data in a normalized (standardized) fashion using an object type management system that allows the arbitrary coercion of one type of object into another different type of object and automatically resolves attribute dependencies. In one embodiment, the MODMS comprises an object type management subsystem; a meta-object instantiation subsystem; one or more data repositories that hold, for example, the data used to populate objects and object type definitions; and an input/output interface.

  • Publication number: 20040230017
    Abstract: The production of a protein free synthetic polyisoprene which has both low levels of chemical impurities and good physical properties has yet to be realized. It has now been envisioned that the use of neodymium catalyzed polyisoprene will offer the combined advantages of both a clean, as well as, high cis-1,4 polymer. Synthesis of polyisoprene rubber using a neodymium based catalyst system is described. Characterization of the material shows the absence of an ultra high molecular weight fraction and the presence of very high cis-1,4-microstructure. Gum stock and black filled compound studies comparing neodymium polyisoprene with natural rubber, titanium polyisoprene, and lithium polyisoprene have been performed. Results indicate that polyisoprene rubber synthesized using a neodymium catalyst system (Nd-PI) has similar stress-strain and tear properties as synthetic titanium polyisoprene.

  • Publication number: 20040127659
    Abstract: This invention is based upon the discovery that rubbery polymers having a high vinyl content and a low degree of branching can be synthesized with an initiator system that is comprised of (a) a lithium initiator selected from the group consisting of allylic lithium compounds and benzylic lithium compounds, (b) a Group I metal alkoxide, and (c) a polar modifier; wherein the molar ratio of the Group I metal alkoxide to the polar modifier is within the range of about 0.1:1 to about 10:1; and wherein the molar ratio of the Group I metal alkoxide to the lithium initiator is within the range of about 0.01:1 to about 20:1. These high vinyl polymers offer reduced levels of hysteresis and better functionalization efficiency.
