The present disclosure relates to a gas filtering device that allows to cover and filter gases emanating from liquid and/or solid substances without the use of auxiliary technologies. The gas filtering device comprises an air tight geomembrane that is adapted to cover and seal the surface from which the gas emanations come from, one or more air permeable filtering cartridge pocket(s) embedded within the air tight geomembrane that are adapted to adopt an opened configuration and a closed configuration, and one or more corresponding filtering cartridge(s) that are releasably secured within the air permeable filtering cartridge pocket.

Disclosed herein are phase separator devices, and related methods of fabrication and use. The disclosure provides improved phase separator devices for phase separation of input feeds, and systems/methods for utilizing and fabricating the devices. The disclosure provides phase separator devices utilizing inertial separation and porous media extraction for the phase separation of two-phase input feeds (e.g., to separate an input feed of a two-phase mixture to a first phase output (e.g., to a liquid output flow) and to a second phase output (e.g., to a gas output flow)). The device can separate a mixed fluid flow of both liquid and gases. The liquid and gas can include liquid and vapor phases of the same chemical/constituent (e.g., ammonia), or may include liquid and gases of two different constituents (e.g., liquid water and air). The phase separator devices can be utilized at standard gravity to micro-gravity to zero gravity environments.

This present description discloses a combined air filter element filtering device, where the first filter element and second filter elements have a cube or cuboid shape. The second filter element and the first filter element are oriented in sagittal symmetry. The third filter element and the fourth filter element are oriented in symmetric distribution at the two sides of the first filter and second filter elements. The third filter element and the fourth filter element are in a semicircular or semi-arc ring structure. The first filter element, second filter element, third filter element and fourth filter element, when assembled into the combined air filter element device form a kidney-shaped or an oval three-dimensional ring-shaped combined air filter element filtering device. First, second, third and fourth filter elements are arranged to allow axial passage of air through the filter elements with decreased resistance and improved volume in order to reduce the air intake resistance in the filter element and increase the filter area so as to provide a combined air filter element filtering device of the same dimensions as conventional filters yet having a higher air inlet volume and improved clogging capacity, higher filtering efficiency and service life.

A water filtration device is provided including a pressurized gas chamber receiving a pressurized gas; an open flow chamber receiving a colloidal suspension including water and colloidal particles, the open flow chamber having an inlet and an outlet, the colloidal suspension flowing between the inlet and at least one outlet in a flow direction; and a gas permeable membrane separating the gas chamber and the flow chamber, the gas capable of permeating the membrane, the membrane being water impermeable, the gas permeating the membrane in a direction normal to the membrane so as to induce diffusiophoretic motion on at least some of the colloidal particles opposite to or in a direction normal to the membrane; the at least one outlet having a first outlet with water having a higher concentration of the colloidal particles than a second outlet. Other devices and methods are also provided.

The invention discloses a reticle storage device including a top lid, a bottom lid and a soft contact member. The top lid has a ceiling and a cover surrounding the ceiling. The bottom lid has a carrier and a peripheral structure surrounding the carrier. The soft contact member is configured to laterally extend in between the cover and the peripheral structure when the top lid and the bottom lid engage with each other, and to extend from an inside to an outside of the device in order to buffer the contact among the two lids.

The present invention provides a quick-release valve module which includes a flexible grommet defining a channel, and a piston having a disc portion at an end thereof, wherein the disc portion of the piston is exposed to the flexible grommet.

A reticle storage device includes a top lid having a ceiling and a cover surrounding the ceiling, and a bottom lid having a carrier and a peripheral structure surrounding the carrier. When the top lid engages with the bottom lid, a passage is defined therebetween and therefore the reticle storage device is not sealed.

An adsorbent breather assembly for filtering contaminants such as particulars and vapor phase contaminants, e.g. volatile organic compounds, for use with electronic devices can include a blocking region adjacent to the adsorbent filter layer to improve filtering performance.

An improved evaporative emission mitigation system for a motor vehicle includes a canister filled with an adsorbent material connected to a membrane module. The membrane module contains a membrane that separates gaseous hydrocarbons from inert air components within fuel vapor generated by the evaporation of fuel due to the heating of the motor vehicle. The gaseous hydrocarbons separated by the membrane are returned to the canister, where they will again be adsorbed by the adsorbent material. The inert air components are vented from the membrane module into the open atmosphere outside of the motor vehicle.

A filtration vessel, having within constituent filter media is formed using plastic injection molding to meet the interior specifications of a high-pressure filtration encasement system while remaining a separate replaceable component. The encasement system supports and encases walls of the filtration vessel enabling the vessel to be designed with sufficient strength and resiliency to form a seal and constrain filter media prior to and after use without necessitating construction to endure independent high-pressure operations. The bottom or base of the vessel includes a plurality of holes through which the filtrate may flow. Interposed between the base of the vessel and the filter media is a semi-permeable barrier imbedded into the injection molded walls and base of the vessel. The barrier prevents residue from contaminating the filtrate.
