    摘要： A flow control element is provided for use in selectively controlling the flow of a liquid through an annular conduit. The flow control element comprises a self-sustaining, three dimensional fibrous element comprising a network of polymeric fibers. These fibers are disposed in a highly dispersed and randomly spaced orientation and are bonded to each other at spaced apart points of contact to form a tortuous interstitial passage through the fiber element. The fibrous element has a substantially uniform density and is sized for disposition in the lumen with an interference fit relative to the inner conduit surface. The fibrous element divides the lumen into a proximal lumen portion and a distal lumen portion when so disposed. The fibrous element is adapted to prevent passage of the liquid through the conduit when disposed therein absent a differential pressure between the distal conduit portion and the proximal conduit portion of at least a first predetermined critical differential pressure. The fibrous element allows passage of the liquid through the conduit when the differential pressure between the distal conduit portion and the proximal conduit portion equals or exceeds the first predetermined critical differential pressure. In some embodiments, the fibrous element may also be adapted so that it will move from its first position in the lumen to a second position when the differential pressure between the distal conduit portion and the proximal conduit portion equals or exceeds a second predetermined critical differential pressure.

    摘要： Filter elements are provided for removing a liquid challenge material dispersed in a carrier fluid. The filter element comprises a three dimensional, self-sustaining, fluid transmissive body comprising a plurality of thermoplastic fibers bonded to each other at spaced apart points of contact. The fibers collectively define a tortuous fluid flow path through the fluid transmissive body from a fluid inlet surface to a fluid outlet surface. At least a portion of the thermoplastic fibers comprise a surface-forming material having a surface energy that is less than a surface tension of the challenge material.

    摘要： The invention is generally directed to a vapor emitting device having a container, at least one liquid in the container, and a wick. The container has an interior in which the at least one liquid is disposed. The wick has a distal portion disposed in the container interior and a proximal portion. The wick is configured and positioned so as to maintain contact with the at least one liquid and allows the wick to draw the at least one liquid into and through the distal portion toward the proximal portion, thereby making the at least one liquid available for evaporation when the proximal portion is exposed to air. A change in a visible characteristic of the wick occurs upon exhaustion of the at least one liquid from the wick.
