Abstract: Embodiments herein relate to an ostomy bag filter. In an embodiment, a filter assembly for venting gas from an ostomy bag is included having a first layer, an adhesive layer, an adsorbent element, and a second layer, the second layer configured to be welded to the ostomy bag at an annular weld area surrounding the second opening; wherein the adhesive layer is configured to adhere to the first layer, the adsorbent element, and the second layer, such that the first opening overlaps with the second opening; wherein the filter assembly is configured such that, when the filter assembly is welded over to the ostomy bag, gas from the ostomy bag flows axially through the adsorbent element and exits the filter assembly through the second opening; and wherein perimeters of the first layer, the adhesive layer, and the second layer are substantially aligned. Other embodiments are also included herein.

Abstract: A fume extractor has an extractor housing (110, 210) defining an outlet (106, 206). A hose (120, 220) is coupled to the extractor housing that defines a first inlet (102, 202). A diffusion plate (130, 230) is coupled to the extractor housing that defines a plurality of openings (132, 232) cumulatively defining a second inlet (104, 204). A fan (280, 530) is disposed in the extractor housing, where the fan configured to connect each of the first inlet and the second inlet to the outlet. A first supporting surface (160) is opposite the diffusion plate relative to the extractor housing and a second supporting surface (170) at least 80° to the diffusion plate, where the first supporting surface and the second supporting surface are configured to selectively rest on a planar surface. The fume extractor defines a hose channel (140) configured to selectively receive the hose.

Abstract: A dosing and mixing assembly for an exhaust aftertreatment device includes a conduit arrangement defining overlapping, coaxial flow paths that join at a common flow path. The conduit arrangement defines a mixing region upstream of the overlapping, coaxial flow paths, an impact region at the overlapping, coaxial flow paths, and a merge region where the coaxial flow paths join. The outer of the coaxial flow paths insulates the inner of the flow paths at least as the impact region. Reactant can be dispensed into the inner flow path along a spray path that intersects the impact region of the conduit arrangement. A spray protector can be provided at or upstream of the mixer to

Abstract: A particle catcher for capturing entrained particles in a fluid is disclosed. The particle catcher can include an enclosure defining a flow channel between an inlet and an outlet. Trapping means may be incorporated into the particle catcher. Where provided, the trapping means can be arranged at or near the inlet to allow fluid comprising entrained particles to enter the flow channel through the inlet and to substantially prevent the fluid comprising entrained particles from exiting the flow channel through the inlet. Filtering means may also be incorporated into the particle catcher. Where provided, the filtering means can be arranged at or near the outlet to keep at least some a part of the entrained particles from exiting the flow channel through the outlet.
