  • Patent number: 11938733
    Abstract: A micro-valve includes an orifice plate having a first surface, a second surface and an orifice extending from the first surface to the second surface. An actuating beam is disposed in spaced relation to the orifice plate. The actuating beam includes a base portion and a cantilevered portion. The base portion is separated from the orifice plate by a predetermined distance. The cantilevered portion extends from the base portion such that an overlapping portion thereof overlaps the orifice. The actuating beam is movable between a closed position and an open position. The micro-valve also includes a sealing structure including a sealing member disposed at the overlapping portion of the cantilevered portion. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve.

  • Publication number: 20230212341
    Abstract: Grafted, crosslinked cellulosic materials include cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of said cellulose fibers and said polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such materials are characterized by a wet bulk of about 10.0-17.0 cm3/g, an IPRP value of about 1000 to 7700 cm2/MPa·sec, and/or a MAP value of about 7.0 to 38 cm H2O. Methods for producing such materials may include grafting polymer chains from a cellulosic substrate, followed by treating the grafted material with a crosslinking agent adapted to effect crosslinking of one or more of the cellulosic substrate or the polymer chains. Example crosslinking mechanisms include esterfication reactions, ionic reactions, and radical reactions, and example crosslinking agents include pentaerythritol, homopolymers of the graft species monomer, and hyperbranched polymers.

    Abstract: The present disclosure features a feminine hygiene product, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.

  • Patent number: 11339532
    Abstract: Methods of forming crosslinked cellulose include mixing a crosslinking agent with cellulose mat fiber fragments composed of hydrogen-bonded cellulose fibers and having a solids content of about 45-95% to form a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers, drying the resulting mixture to 85-100% solids, then curing the dried mixture under conditions effective to crosslink the cellulose fibers. Some of such methods may include fragmenting a cellulose fiber mat to form the mat fragments. Systems include a mixing unit (such as a high-consistency mixer) configured to form, from the mat fragments and a crosslinking agent, a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers and crosslinking agent, at ambient conditions, a drying unit to dry the substantially homogenous mixture to a consistency of 85-100%, and a curing unit and to cure the crosslinking agent to form dried and cured crosslinked cellulose fibers.

  • Patent number: 10458790
    Abstract: The present disclosure relates to a space and dimension determining device, which is useful for placement, mounting, hanging and leveling a picture, shelving, or any other object onto a receiving surface. The present device is capable of locking into position capturing the dimensions and allowing for “measureless” transfer of dimensions from one place to another. The present disclosure further relates to a device incorporating a laser, either as part of, or a separate, attachable feature to, the present device, the laser being useful for assisting in determining center points, and a plurality of dimensions and readings equal distance from the center point. The present disclosure also relates to a system and method of transferring dimensions from a space determining device to an electronic communication device, which is used to create a template for placement of an item or items within a target space.
