Abstract: An interface for positive pressure therapy includes a mask assembly. The mask assembly comprises a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose. The mask seal comprises a rolling hinge that permits one portion of the mask seal to deform relative to another portion of the mask seal. In one configuration, the portion of the mask seal that underlies the nose is configured to deform relative to a lower portion of the mask seal.

Abstract: An arrangement of insulation within a container to prevent heat leakage from the ambient to an apparatus located within the container that operates at a cryogenic temperature. The arrangement of insulation includes bulk insulation filling the container and an insulation layer that is located within the container, between the apparatus and the container. The insulation layer as opposed to the bulk insulation has a lower thermal conductivity. An exterior region of the apparatus is situated closer to an opposite container wall region of the container than remaining exterior regions of the apparatus. The insulation layer is sized to only insulate the exterior region of the apparatus from heat leakage from the opposite container wall region. The insulation layer can be formed of an aerogel.

Abstract: In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.

Abstract: A system, method and capsule are usable for preparing a predetermined quantity of beverage suitable for consumption using an extractable product. The system includes an exchangeable capsule, and an apparatus including a receptacle for holding the exchangeable capsule, and a fluid dispensing device for supplying a fluid to the exchangeable capsule. The exchangeable capsule includes a circumferential wall, a bottom, and a lid. The wall, bottom and lid enclose an inner space including the extractable product. The receptacle includes bottom piercing means intended for piercing an entrance area of an alternative capsule for creating at least one entrance opening for supplying the fluid to the extractable product. The entrance area of the capsule includes an entrance filter for supplying the fluid to the extractable product there through. In use, the entrance filter is positioned at a distance from the bottom piercing means, such that the capsule of the system is not pierced by the bottom piercing means.

Abstract: A capsule for preparing a predetermined quantity of beverage suitable for consumption using an extractable product is disclosed. The capsule includes a circumferential first wall, a second wall closing the circumferential first wall at a first end, and a flexible sheet-shaped third wall closing the circumferential first wall at a second, open, end opposite the second wall, the third wall being at least one of perforate and porous. The first, second and third wall enclose an inner space including the extractable product. The third wall forms an outermost boundary of the capsule in an axial direction thereof. The third wall includes a filtering material. The second wall is one of a flexible porous sheet, a flexible foil provided with a plurality of entrance openings, and a substantially rigid wall that comprises a plurality of entrance openings.

Abstract: A capsule, system and method for preparing a predetermined quantity of beverage suitable for consumption using an extractable product is shown. The capsule includes a circumferential first wall, a second wall closing the circumferential first wall at a first end, and a flexible sheet-shaped perforate and/or porous third wall closing the circumferential first wall at a second, open, end opposite the second wall. The first, second and third wall enclose an inner space including the extractable product. The third wall forms an outermost boundary of the capsule in an axial direction thereof. The third wall comprises a woven or nonwoven filtering material, such as filtering paper.

Abstract: A system including a capsule is usable for preparing a predetermined quantity of beverage suitable for consumption using an extractable product. The system includes a substantially rigid circumferential wall, a bottom closing the circumferential wall at a first end, and lid of a flexible sheet-shaped perforate and/or porous material closing the circumferential wall at a second, open, end opposite the bottom. The circumferential wall, the bottom and the lid enclose an inner space include the extractable product, and the lid includes an impermeable outer circumferential area and an exit area being enclosed by said impermeable outer circumferential area such that, in use, the prepared beverage is drained from the capsule through the exit area.

Abstract: A multistage compressor installation in which compression stages utilizing centrifugal compressors are independently driven by drivers that can be electric motors configured to be controlled by a speed controller. Intercoolers are located between stages to remove the heat of compression and the stages are connected such that outlets are located opposite to inlets of the compressors and conduits connecting the intercoolers to the stages are in an in-line relationship to inhibit the formation of pressure drops between stages. The conduits connecting the stages incorporate tapered transition sections configured such that flow velocity gradually decreases towards the intercooler and gradually increases from the intercooler to the next succeeding compression stage to further inhibit pressure drops.
