    摘要: A process for making nanofibers includes preparing a fluid suspension of fibers, shear refining the fibers to create fibrillated fibers, and subsequently closed channel refining or homogenizing the fibrillated fibers to detach nanofibers from the fibrillated fibers. The shear refining of the fibers in the fluid suspension generates fiber cores having attached nanofibers. The closed channel refining or homogenizing of the fibrillated fibers is initially at a first shear rate and, subsequently, at a second, higher shear rate, to detach nanofibers from fiber cores and to create additional nanofibers from the fiber cores. The fiber suspension may flow continuously from the shear refining to the closed channel refining or homogenizing, and include controlling the rate of flow of the fiber suspension from the shear refining to the closed channel refining or homogenizing.

    摘要: A tangential air filter configuration is designed for applications where there is a potential for a pollutant to back flush out. The tangential in-line air filter reduces air resistance and prevents back flow, allowing the air to traverse through a forced air system during operation without resistance, and absorbs particulates and prevents back flow of fuel vapors when the forced air is at a standstill. The filter medium has a plurality of pleats or corrugations with a longitudinal axis parallel to the forced airflow direction. A diffusion barrier is formed when the forced air is at a standstill. Vapors are not passed or forced through the filter medium; rather pollutants are aggressively absorbed during diffusion.
