  • Patent number: 12138569
    Abstract: A filter cartridge endplate (12) is described herein that has a integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (12), where a separator (10) is built into the endplate (12) the separates fluid flow. The endplate (12) includes a plate with a major surface, a separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) ae configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate (12).

  • Publication number: 20230138993
    Abstract: A fiber-based, plastic-free drinking cup is formed by providing a fiber-based slurry comprising a hydrophobic additive and a strength additive, then forming a drinking cup component by compressing and drying the fiber-based slurry in a form press assembly having an internal shape characterized by a conic frustum. The fiber-based slurry may include a dry pulp mixture of virgin fiber and recycled fiber, the hydrophobic additive is 1.0-10.0% of the dry pulp weight, and the strength additive is 1.0-10.0% of the dry pulp weight. In particular, the fiber-based slurry may include about 50% bleached hardwood, about 50% bleached softwood, about 2.5% strength additive, and about 3.5% hydrophobic additive by dry pulp weight.
