  • Publication number: 20190152613
    Abstract: A pneumatic de-icer includes an externally facing weathering surface that includes a low-friction additive in the rubber mixture. The low-friction additive has a coefficient of friction of 0.10 or less, and promotes ice shedding because the additive has low ice adhesion compared to typical rubber materials used for pneumatic de-icer assemblies.

  • Patent number: 9623369
    Abstract: A hollow fiber fluid separation device includes a hollow fiber cartridge, comprising a plurality of hollow fiber membranes arranged around a central tubular core, a first tubesheet and a second tubesheet encapsulating respective distal ends of the hollow fiber bundle. The tubesheets have boreholes in fluid communication with bores of the hollow fiber membrane. In at least one of the tubesheets, the boreholes are formed radially and are in communication with the central tubular core. The hollow fiber fluid separation device can be utilized in liquid separation applications such as ultrafiltration and in gas separation processes such as air separation. The design disclosed herein is light weight and compact and is particularly advantageous at high operating temperatures when the pressure of the feed fluid introduced into the bores of hollow fibers is higher than the pressure on the shell side of the device.
