Edge Supporting Or Securing Means For Nonplanar Sheet Form Filter (e.g., Zigzag) Patents (Class 55/497)
  • Patent number: 11975286
    Abstract: Collapsible filter assembly includes a filter medium element and a frame at least partially surrounding the filter medium element. The frame and filter media element are configured to vary in at least two dimensions by folding or unfolding. In at least on example, the filter medium element is rectangularly pleated or round pleated. Upon removal of the filter assembly from packaging and other restraints, the filter assembly may naturally expand with regard to footprint and volume, with some manual assistance being expected of a typical user in unfolding from an area-reduced configuration to an area-expanded configuration, and from a volumetrically reduced configuration to a volumetrically expanded configuration.

  • Patent number: 11958007
    Abstract: A filter element includes a frame having an outlet panel and two side panels defining a U-shape. A U-shaped media anchor channel extends along the distal side edge of each panel. Each media anchor channel can have a snap-tab or other locking feature. The element encloses a pleated panel filter media pack having a side edge along each side of the pack. Each side edge of the media pack is located in a media anchor channel, and a bead of adhesive is applied along the channel. A pair of seal bars, each having a u-shape and a snap-tab or other feature that cooperates with the u-shape and the snap-tab of each media anchor channel, is pressed into each channel. Each seal bar mechanically retains a respective media side edge in the channel and together with the adhesive, provides a consistent, robust seal between the media and the frame.

The support backing has a planar configuration with openings formed through it so that gas can flow through without substantial resistance. The preferably planar sheet of which the support backing is made is pleated. The pleated support backing defines a series of panels, each of which is angled to a next adjacent panel. Filtration media is mounted to the support backing, end caps are attached to the ends of the support backing to maintain the pleated configuration, and the assembly is inserted into the housing, which can have end flaps to seal using tape or adhesive.

  • Patent number: 10479046
    Abstract: Absorbent microstructure panels are described herein. An example filter device includes a plurality of microstructure panels each having a front surface and a back surface, and a plurality of capillary ridges protruding from the front surface. The plurality of capillary ridges are each spaced apart from one another. The plurality of microstructure panels form an absorbent microstructure array by layering the plurality of microstructure panels together such that the plurality of capillary ridges of one microstructure panel contacts the back surface of an adjacent microstructure panel to create capillary tubes that draw fluid into the absorbent microstructure array.

  • Patent number: 10392489
    Abstract: A method for making ornamental trim for use in construction comprising applying a sealing composition having PVC particles in a flowable medium to a cut edge of a foam board, heating the sealing composition to a temperature at which the flowable medium solvates the PVC particles, and cooling the sealing composition to form a continuous sealing cap on the cut edge. A construction component consisting essentially of a foamed cellular board comprising smooth exterior surfaces separated by a cellular network and cut edges, and sealed caps adhered to the cut edges on the foamed cellular board comprising PVC in a polymer matrix. The board has a density of no more than 0.5 g/cm3, and the cut edges on which the sealed caps are adhered are unmelted edges.

  • Patent number: 10213721
    Abstract: An air filter arrangement incorporates a replaceable pleated air filter element which is installed in a rectangular frame. The air filter element is collapsible by flattening together the pleats and placed in an opening in the frame and thereafter stretched apart to extend across the space opposite frame sides and held in that position, by a magnetic element on the end pleat at either end of the air filter element. Sealing pads made of a material similar to the filter element panels are secured to the other two opposite frame sides which engage respective opposite ends of the air filter element for reducing air flow around the pleat ends. A planar lattice restraint is held in a perimeter slot extending around the frame opening to prevent contact of the air filter element and the lattice restraint to minimize the risk of holes being torn in the filter element by such contact.
