  • Patent number: 10997556
    Abstract: A method, system, and computer program product for enterprise applications. Embodiments commence by accessing a first database table having columns pertaining to one or more cost items of a first project and accessing a second database table having columns pertaining to cost items of a second project. A user interface aids definition of user-defined inter-project attributes, wherein the user-defined inter-project attributes relate a database table column of the first project to a database table column of the second project. The user-defined inter-project attributes are used in preparing display information pertaining to at least two projects such that in response to a single action being performed under control of a client system, the prepared display information is sent to a display unit. In some cases, the prepared display information comprises a summary of values, and in some cases, an alert icon is displayed based on a summary value exceeding a threshold.

  • Patent number: 10273321
    Abstract: Solid catalyst components for use in olefin polymerization, olefin polymerization catalyst systems containing the solid catalyst components, methods of making the solid catalyst components and the catalyst systems, and methods of polymerizing and copolymerizing olefins involving the use of the catalyst systems. The solid catalyst components are formed by (a) dissolving a magnesium compound and an auxiliary intermediate electron donor in at least one first solvent to form a solution; (b) contacting a first titanium compound with said solution to form a precipitate of the magnesium compound and the first titanium compound; (c) washing the precipitate with a mixture of a second titanium compound and at least one second solvent and optionally an electron donor at a temperature of up to 90° C.; and (d) treating the precipitate with a mixture of a third titanium compound and at least one third solvent at 90-150° C. to form a solid catalyst component.

  • Patent number: 9403924
    Abstract: Solid catalyst particles for use in olefin polymerization, olefin polymerization catalyst systems containing the solid catalyst particles, methods of making the solid catalyst particles and the catalyst systems, and methods of polymerizing and copolymerizing olefins involving the use of the catalyst systems. The method of preparing the solid catalyst particles includes steps of maintaining a mixture of reactants at a temperature of about 5° C. to about 35° C. for at least 2 hours; increasing the temperature of said mixture to a temperature of about 40° C. to about 50° C. over a period of at least 3 hours; and increasing the temperature of said mixture to a temperature of about 80° C. to about 90° C.

  • Patent number: 8685879
    Abstract: Disclosed are spherical magnesium-based catalyst supports and methods of using the same in a Ziegler-Natta catalyst system for the polymerization of an olefin. The spherical magnesium-based catalyst supports are made by reacting a magnesium halide, a haloalkylepoxide, and a phosphate acid ester in an organic solvent that does not have to contain substantial amounts of toluene.
