  • Patent number: 10513571
    Abstract: Methods of preparing a polymerization catalyst component is provided, in which a magnesium component, a Lewis acid solubilizing component, a titanium compound, optionally a transition metal compound different than the titanium compound, and typically an inert filler are combined in a slurrying agent and spray-dried to produce a catalyst precursor in the form of a substantially spherical and porous solid particle. The methods and catalysts of this disclosure can provide ethylene homopolymer and copolymer resins having a high molecular weight tail and a broadened molecular weight distribution as compared to more traditional Ziegler-Natta catalysts.

  • Patent number: 10390546
    Abstract: One embodiment of an apparatus with mobile reusable airtight container assembly (10) which utilizes pressurized inert gas or CO2 gas for long term preservation of the freshness of roasted coffee beans or grounds in terms of aroma and taste, utilizes a system of an electronic controller (250), pressure switch (170), gas delivery valve (180), check valve (50) and vent valve (160) to create a pressurized environment of inert gas or CO2 gas and low residual oxygen and moisture concentrations within the airtight container assembly (10). An airtight lid (20) with pressure seal (220) covers the airtight container assembly (10) and creates a reusable system whereby the user can remove a portion of the roasted coffee beans or grounds as often as needed in order to brew coffee without degrading the long term freshness of the roasted coffee beans or grounds stored within the airtight container assembly (10).

  • Publication number: 20190133837
    Abstract: A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter.

  • Patent number: 10221263
    Abstract: A catalyst system for polymerizing olefin-based polymers and interpolymers is disclosed. The catalyst system may include a supported chromium catalyst and a Ziegler-Natta catalyst comprising a bulking agent, Mg, and Ti. The Ziegler-Natta catalysts in catalyst systems disclosed herein run exceptionally well without addition of excessive amounts of co-catalyst, thus allowing for use of chromium based supported catalysts that would otherwise be overwhelmed by aluminum alkyl. Further, embodiments disclosed herein may be run without an internal electron donor, and the lack of an internal electron donor in the system also prevents poisoning of the chromium catalysts by the internal electron donor. By including or co-feeding a chromium based catalyst with these Ziegler-Natta catalysts, it has been found that the molecular architecture of the resulting polyolefins, such as polyethylenes, may provide for resins with excellent processing properties.
