Abstract: A cartridge comprising layers of adsorbent sheet is described. The cartridge includes an indicator that characterizes the consumption state of the adsorbent within the cartridge. The indicator is applied in a way such that discrete areas of indicator are visible. These discontinuous areas of indicator may be applied to the outside surface of the cartridge. Alternatively, the discontinuous areas may be formed by cutting windows in the outermost layer of the cartridge and either coating indicator on the layer beneath the window, placing an indicator layer between the window and the layer beneath it or filling the window with an indicating plug of material so that the indicator is visible from the outside of the cartridge. The indicator layer and indicator plug embodiments allow the use of any indicator with any adsorbent.

Abstract: An adsorbent is described. The adsorbent may include a membrane and an adsorbent material encapsulated within the membrane. An inhalation device is also described. The inhalation device may include a housing and a membrane within the housing. The membrane may encapsulate an adsorbent material. The membrane may be positioned such that airflow through the housing passes across but not through the membrane.

Abstract: A method of processing carbon dioxide adsorbent for use in a CO2 removal system. The method includes combining a polymer, lithium hydroxide (LiOH), and lubricant that dissolves the polymer to form a first LiOH adsorbent. A structure may be formed using the first LiOH adsorbent. The lubricant may be extracted from the structured LiOH adsorbent using a solvent to form a second LiOH adsorbent. The solvent may be removed from the second LiOH adsorbent to form a third LiOH adsorbent. The third LiOH adsorbent may be hydrated to form a fourth LiOH adsorbent having a water content above an anhydrous level.

Abstract: A CO2 removal system including a member having a first opening and a second opening to enable air flow containing carbon dioxide (CO2) to pass from the first opening to the second opening and lithium hydroxide (LiOH) supported by the member and having an initial water content above an anhydrous level. In one embodiment, LiOH adsorbent density is a maximum of approximately 1.0 g/cm3.

Abstract: A gas absorption rebreather canister containing at least one sheet embodying adsorbent material inside and a portion of the sheet spaced apart by a separating means. The sheet being arranged so that expelled gases entering the canister pass along the canister interior substantially parallel with a surface of the sheet. The sheets can be formed with an internal screen positioned between two gas-permeable, liquid-water resistant membranes and the adsorbent material positioned within interstices between the screen members. Also, the sheets can comprise a sheet of expanded porous PTFE having a microstructure of nodes interconnected with fibrils, said sheet containing gas adsorbent material. The sheet can be covered on each side by a sheet of expanded porous PTFE. This device effectively contains the adsorption material within the sheets even when exposed to liquid water. The result is a rebreather device that is safer, more efficient, and easier to use than any presently on the market.

Abstract: The present invention is an improved container and interface for transporting or otherwise handling contamination-sensitive materials, such as semi-conductor wafers during processing. The container of the present invention employs a door-within-a-door design, allowing the container to connect with different interfaces on a single side. Employing a container of the present invention, manufacturers may connect a single container to different tools or mini-environments employing incompatible interfaces without the need to use different containers or to access the contents of a single container from different directions. The present invention is particularly useful in instances where a single interface standard, e.g., SEMI Standard SMIF interfaces, has not been uniformly adopted in a facility.
