  • Publication number: 20250005467
    Abstract: Methods and apparatuses are described in which unstructured computer text is analyzed for extraction of actionable insights in a computing environment. A server executes a machine learning classification model on text messages exchanged between users to classify each text message according to a disposition and a theme. The server analyzes the classified messages to generate candidate work items, each associated with software applications and skills requirements. The server filters the candidate items to remove extraneous items based upon a work item backlog or a prioritization. The server determines team members to assign to each remaining candidate item by comparing the software applications and the skills requirements for the work item to a profile for each team member. The server creates a task for each remaining candidate item, the task including the assigned team members. The server generates a notification for each task for transmission to the assigned team members.

  • Publication number: 20240177814
    Abstract: A system for standardizing medical testing data may include a processor. The processor may be programmed to access a first medical testing record including a first data element represented in a first data format; access a second medical testing record including a second data element represented in a second data format, the second data format being different from the first data format; determine that the first data element and the second data element are associated with a common value classifier; and store the first data element and the second data element in a database in association with the common value classifier.

  • Publication number: 20180231312
    Abstract: There is disclosed a vertical vibratory thermal treatment system, comprising a heating section for thermally treating material, a retort section that is located within or connected to the heating section and includes at least one elevator system for vertically moving the material to the heating section. The disclosed elevator system is isolated from other parts of the thermal treatment section by an enclosure thereby allowing for flexibility and simplicity in the design of the retort section. There is also disclosed a method of treating materials, including hazardous or radioactive materials, such as a powder, sand, granule, gravel, agglomerate or other form of particle or combinations thereof, using the system described herein.

  • Publication number: 20080108817
    Abstract: Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels.

  • Publication number: 20060117499
    Abstract: This invention relates to compositions of N,N?-dialkyleneoxy-substituted 1,4-diaminoanthraquinone colorants which contain a low percentage of impurities, to a process to make the compositions, and also to the use of the compositions thus prepared for coloring consumer products.

  • Publication number: 20060101593
    Abstract: Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) derived structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels. The colorant compositions of the invention are useful as applied in polyolefins, such as polypropylene and polyethylene, as examples. These colorant compositions also may be employed in thermoplastics, such as PET, for example.

  • Patent number: 5334668
    Abstract: Polymeric carbon can be formed by a method comprising the steps of(a) polymerizing 1-bromo-4-lithiobenzene to form a brominated polyphenylene wherein the ratio of brominated to non-brominated residues in the polymer is 1:5 or greater;(b) functionalizing the brominated polyphenylene to replace the bromide groups with a substituted or unsubstituted acetylene group; and(c) heating the functionalized polymer to a temperature of 900.degree. C. to form polymeric carbon. Preferably, the brominated polyphenylene is formed in an ethereal solvent such as tetrahydrofuran and then functionalized using a palladium catalyst and a copper catalyst. When the acetylene substituent is phenylacetylene, the product of the method is glassy carbon.
