Functional filters for hydrophobic liquid/hydrophilic liquid separations

A composite material is described that is an effective filter to separate oil from an oil and water emulsion or other mixtures of oil and water. The composite material has a permeable substrate, such as fabric, that is coated with a selectively-permeable coating. The composite material allows only oil to pass through, while water is prevented from passing through. The composite material has two main components, a hydrophobic component and an emulsion-destabilizing component.

Passive particle separation system

One embodiment is a passive particle separation system including a plenum; an inlet for feeding outside air into the plenum, wherein the outside air has particles entrained therewith; a housing for enclosing the plenum; and a standpipe installed on the housing. The outside air enters the plenum via the inlet and plenum, housing, and standpipe interact to impact the outside air entering the plenum to cause the particles to be released from the outside air.

Separator

A separator for separating one or more components selected from particulate material, hydrophobic material, non-polar material, microorganisms, or viruses from a mixture of water and the one or more components or from a mixture of a polar liquid and the one or more components, the separator comprising a layer of a metal hydroxide hydrate.

Durable nanofiber synthetic filter media
10799820 · 2020-10-13 · ·

A present invention is directed to a laminated filtration media comprising a nanofiber coating applied onto a synthetic substrate. Generally, the laminated filtration media can be produced by applying the nanofiber layer onto the synthetic substrate via an electrospinning process and then thermo-mechanically bonding the nanofiber layer onto the synthetic substrate via a thermal bonding process. The laminated filtration media exhibits superior durability and can be used in a wide array of air filtration applications.

Jet engine with deflector
10774744 · 2020-09-15 ·

An air inlet deflector for a structure having an air inlet. The deflector may be retractable within the structure, may be integrally formed with the structure, and may prevent the structure from ingesting foreign matter, such as birds. The deflector may include a series of ribs, spokes, or vanes that may vary in width and/or thickness from fore to aft, and/or may be curvilinear in one or more planes of view, and/or may serve double duty as inlet vanes for redirecting inlet air.
