A dehumidifying element includes a plurality of sheets that have moisture adsorption and desorption properties and that are stacked on top of each another. At least some of the sheets each have an irregular shape. The sheets each contain a hygroscopic agent having properties of a re-moistening-type glue that exhibits adherence when adsorbing moisture and that solidifies when being dried. The sheets are bonded to each other by the hygroscopic agent.

A vehicle includes an engine, at least three wheels including a front wheel and a rear wheel, a fuel tank above the engine, a seat rearward of the fuel tank, a canister positioned lower than the fuel tank, and a vent hose to supply air therethrough into the canister to desorb the adsorbed fuel evaporative emission from the canister. An upstream end of the drain hose is connected to the vent hose. A downstream end of the drain hose is positioned lower than the canister.

The present disclosure describes an evaporative emission control canister system that includes: one or more canisters comprising at least one vent-side particulate adsorbent volume comprising a particulate adsorbent having microscopic pores with a diameter of less than about 100 nm; macroscopic pores having a diameter of about 100 - 100,000 nm; and a ratio of a volume of the macroscopic pores to a volume of the microscopic pores that is greater than about 150%, and having a retentivity of about 1.0 g/dL or less. The system may further include a high butane working capacity adsorbent. The disclosure also describes a method for reducing emissions in an evaporative emission control system.

A receptacle is designed for a chamber for an active substance. The receptacle includes two main elements. A first element is a transverse wall with a first main side facing an interior of the chamber, and a peripheral wall formed with the first main side of the transverse wall. A second element includes a bottom wall and a sheath extending from the bottom wall. The peripheral wall and the sheath surround one another and are in contact with each other so that the chamber is formed between the bottom wall, the transverse wall, the peripheral wall and/or the sheath. At least one ventilation groove is provided between the peripheral wall and the sheath form a ventilation channel connecting the chamber with the outside atmosphere.

A swing bed absorption apparatus includes a bed including a bed housing including, an outer surface, an interior chamber, and a flared interior passageway fluidly connecting the interior chamber to an area located outside of the bed. The flared interior passageway includes an opening in the outer surface, a chamber opening at the interior chamber, a first portion located at the opening, the first portion being fluidly connected to the area located outside the bed through the opening, and a flared portion located at the chamber opening, the flared portion being fluidly connected to the interior chamber through the chamber opening. The flared portion connects to the interior chamber at an obtuse angle.

There is provided a structurally stable monolith substrate, suitable to provide carbon dioxide capture structure for removing carbon dioxide from air, having two major opposed surfaces, and further having a plurality of longitudinal channels extending between and opening through the two major opposed surfaces of the structurally stable monolith substrate; and a macroporous coating, adhered to the interior wall surfaces of the longitudinal channels, comprising an adherent, coating formed of cohered, compact mesoporous particles each being formed of a material that is compatible with the material forming the underlying substrate structure so as to become adherent thereto when coated. The mesoporous particles are capable of supporting in their mesopores a sorbent for CO.sub.2 There is also provided a method for forming the monolith and a system for utilizing the monolith as part of a CO.sub.2 capture structure, within the system, to remove CO.sub.2 from the atmosphere.

A dehumidifying element includes: a layered body in which a plurality of sheets supporting an adsorbent that dehumidifies air are stacked on one another, with gaps provided between adjacent ones of the plurality of sheets, the gaps allowing air to pass therethrough; a casing that holds the layered body; and a cushioning member provided between the casing and the layered body in a stacking direction in which the plurality of sheets are stacked on one another, the cushioning member being configured to expand and contract.

A smart multi-modal vehicular air filtration management system including a first filter element and a second filter element disposed in a fresh air housing, wherein the fresh air housing has an inlet and an outlet. Additionally, a third filter element is provided which is disposed in a cabin housing, the cabin housing having one or more inlet. A fluid channel arranged between the fresh air and cabin housing. Finally, a diverter is included which is disposed near an outlet of the fresh air housing, wherein the diverter is configured to cause air to flow through the fresh air housing selectively through one or both of the first filter element and the second filter element.

A portable oxygen concentrator retrofit system and method in which an existing portable oxygen concentrator may be retrofitted to output an enriched oxygen gas at a flow rate suitable for use in a patient ventilation system without the need for an external source of compressed gas.

The present disclosure relates to a charge flap arrangement comprising an engagement feature, a sealing unit for said charge flap arrangement, a hinge arm assembly for said charge flap arrangement and a method for assembling said hinge arm assembly.
