摘要： A filter assembly for an enclosure, particularly for an ostomy bag, is described having an enclosure side, a first layer which is gas permeable, and an adsorbent layer comprising adsorbent particles dispersed in a fine fiber web. The enclosure side of the filter assembly includes an adhesive zone in which adhesive is present having an outer adhesive perimeter and a weld area surrounding at least a portion of the adhesive zone, where the filter assembly is heat-sealable to the enclosure at the weld area. A method of assembly is also described.

摘要： Pleated filtration media, filtration media packs, and filtration elements containing projections are disclosed. The pleated filtration media includes projections on at least one surface, the projections configured to engage adjacent media sheets so as to reduce masking of the media. The pleated media and media pleat packs contain protrusions on the surface of the media. These protrusions are three dimensional structures that are on the surface of the media and are provided by forming the protrusion directly in the filtration media or applying structures, such as adhesive beads, or onto one or both faces of the media. Elongation of the adhesive bead can facilitate greater separation of the adjacent faces of pleated media if desired. These protrusions, also referred to herein as projections or dimples, can either contact each other or contact flat media and keep adjacent media faces from becoming in intimate contact with each other.

摘要： A filter element comprises one or more several tubular filter media element segments, which may be pleated filter media ring segments. One or more heat activated disks are used to connect each tubular filter media element segments together and/or to connect tubular filter media element segments with one or more end cap supports. The heat activated disks are solid in form for assembly with tubular filter media ring segment and then heat activated to bond with tubular filter media ring segments. Multiple end caps can be simultaneously bonded to one or more tubular filter media element segments if a filter stack assembly of component are heated together, such as in an oven. Filter media may also be simultaneously cured. Heat activated disks may be used as pleat stabilizers and/or for and/or as part of end caps.

摘要： A filter cartridge arrangement is provided which includes a media pack comprising Z-filter media, a preform and a housing seal member. Improvements in the preform and seal member are described which include: a single beveled surface of the seal member to facilitate installation; and, an inside region of the seal member having a tip adjacent in inwardly directed lip of the preform, to control flash during molding. A variety of media pack configurations and features are described.

摘要： The invention relates to a particle-trapping device (2) for a turbomachine, said particles being contained in an air stream flowing inside a turbomachine, in particular the air stream flowing in the bypass region (17) of the combustion chamber (13) of said turbomachine. The device is characterized in that it comprises: —at least two particle deflectors (3, 3a, 3b, 3c), —a member (5) for collecting and storing the particles deflected by said deflector, —and means (6) for attaching said trapping device (2) to a part of the turbomachine.

摘要： There is described a method of use of a mass exchanger. In the method the mass exchanger comprises: a first channel for accommodating flow of a liquid to be treated; and a second channel for accommodating flow of a treatment agent, the first and second channels have a permeable membrane provided between them, so as to allow transfer of selected species between the first channel and the second channel. The steps of the mass transfer method comprise passing the liquid to be treated along the first channel and introducing a mixture of liquid and gas into the second channel to provide a two-phase treatment agent. It is desirable to provide a means of adjusting the concentration of gas species in a liquid such as blood, while simultaneously controlling the temperature of the liquid and optionally adjusting the concentration of ionic and/or dissolved species in that liquid. By this method and mass exchanger providing a two-phase treatment agent, it is possible to simultaneously deliver gaseous species (e.g. oxygen) into the treated liquid, while making use of the high heat capacity of the liquid phase of the treatment agent to transfer significant heat into or from the treated liquid.

摘要： A blood plasma and blood cell separation device includes a first body, a blood plasma separation membrane and a second body. The first body has an injection port. The blood plasma separation membrane is disposed on the first body. The second body is movably assembled to the first body and has a collecting stage. The collecting stage has a collecting surface and a sampling recess on the collecting stage. When a blood enters the blood plasma separation membrane from the injection port of the first body, a blood plasma in the blood plasma separation membrane is separated by a capillary force between the collecting stage of the second body and the blood plasma separation membrane, and the blood plasma enters in the sampling recess by a relative movement between the first body and the second body.

摘要： A device for filtering a flow of gas conveying liquid or solid particles in a flow channel. According to the invention, the particles are imparted a speed that is high enough to project same by inertia into the opening of a recovery channel formed inside the flow channel, while the gas from the flow bypasses said opening due to a specific configuration of the flow conditions of a perfect fluid in the flow channel and in the collection channel.

摘要： Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.
