  • Patent number: 11002409
    Abstract: A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

    Abstract: A frame assembly for releasably maintaining an air filter. In some embodiments, the frame assembly includes a thermoformed body integrally forming a base, opposing side walls, opposing end walls, and at least one closure sub-assembly. The frame assembly is configured to releasable retain an air filter relative to the base via the closure sub-assembly. In other embodiments, the frame assembly defines, in a flat state, foldable side and end panels at the perimeter edges of a central grid panel; the frame assembly can be transitioned to a final state for receiving an air filter by folding the panels. The frame assemblies of the present disclosure are re-usable, allowing a user to replace a “used” air filter with a “new” air filter.

  • Patent number: 10986969
    Abstract: A vacuum cleaner dust container having a dust bag, made of an air permeable material, and a connector plate, surrounding an opening in the dust bag. The connector plate is configured by the connector plate being slid into a holder of a vacuum cleaner to correctly position the opening therein. The connector plate has a central portion surrounding the opening, and an extending portion projecting from the central portion. The extending portion has a lower bending stiffness than the central portion about an axis perpendicular to the direction in which it is inserted. Thereby extending portion can be bent out of the plane of the central portion and into a curvature without bending the central portion, which facilitates fitting the connector plate in a vacuum cleaner canister with curved inner walls.

  • Patent number: 10981095
    Abstract: A nonwoven fabric according to the present invention is formed so that constituent fibers of the nonwoven fabric have an average fiber diameter of less than 1 ?m and the number of fibers having fiber diameters ranging from 2 times up to 10 times the average fiber diameter of the constituent fibers is in a range of 2 to 20% of a total number of the constituent fibers.

  • Patent number: 10974191
    Abstract: Disclosed is an aircraft environmental control and fuel tank inerting coupling system based on a membrane separation method. The dehumidification of gas in an aircraft environmental control system and the separation of oxygen and nitrogen in a fuel tank inerting system are realized respectively, based on the selective permeability of a membrane to water vapour/air and oxygen/nitrogen. In the coupling system, part of drying gas passing through a membrane dehumidification heat exchanger (5) enters a membrane air separator (9), and the other part thereof is cooled through a large expansion turbine (8) and then directed into a cockpit for refrigeration; and nitrogen-rich gas generated by the membrane air separator (9) is directed into a fuel tank for inerting. Oxygen-rich gas is mixed with gas supplied by the environmental control system, thus increasing the oxygen content of gas supplied by the aircraft cockpit.
