  • Patent number: 11319124
    Abstract: Beverage filtration device including a lid body having an internal housing configured to hold an ion exchange resin-filed cartridge therein having a connection end and a top end having an opening therein, and, stem body having a cap region, collar, beverage conduit and stem air tube. The cap region couples to the connection end of the lid body to form a liquid-tight seal coupling there-between. A collar wall first portion fits inside a beverage mouth container and a second portion located outside of the mouth. The beverage conduit spans the collar, a first conduit opening open to the coupling between the cap region and the connection end and a second conduit open to a container interior. The stem body air tube extends through the collar, a proximal opening of the stem body air tube opens to an air vent hole located in the second portion of the collar wall, and, a distal opening of the stem body air tube opens to the container interior.

  • Publication number: 20200399569
    Abstract: A device including a lid body including a connection end, a top end having an opening therein, a pouring spout body encompassing the opening, and, a stem body including an internal housing configured to hold an ion exchange resin-filed cartridge therein, a cap region, collar, a beverage conduit, and a stem body air tube. The cap region configured to couple to the connection end of the lid body to thereby form a first liquid-tight seal coupling between the connection end of the lid body and a top end of the ion exchange resin-filed cartridge, and, form a second a liquid-tight seal coupling between a base region of the internal housing and a bottom end of the ion exchange resin-filed cartridge. First and second collar wall portions sized to fit inside a mouth of a beverage container and to be located outside of the mouth. The beverage conduit spans the collar with a first and second openings to the base region and an interior of the beverage container.

  • Patent number: 10223791
    Abstract: Disclosed herein is a method comprising a method comprising imaging a network section through which flow occurs; where the flow is selected from a group consisting of fluid, electrons, protons, neutrons and holes; partitioning the image into sub-regions based on metabolic need and function; where each region comprises one or more sources and one or more sinks; where the flow emanates from the source and exits into the sinks; generating a Voronoi diagram from the Delaunay triangulation by subdividing the sub-regions into Voronoi cells, where each Voronoi cell contains exactly one sink or one source; and where the intersections of Voronoi cells are Voronoi cell vertices; calculating a flow rate in each Voronoi cell; and according a color to Voronoi cells based on their flow rates; where Voronoi cells having similar rates are accorded similar colors.
