摘要： A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

摘要： A device for separating solids from a colloidal solution or suspension utilizing a permeable sheet comprised of passages or openings connecting the up and downstream faces of the sheet, an elastic support, a sealed enclosure separating the solids of the colloidal suspension from the clarified fluid filtered through the device, and a port or other means to allow transfer or collection of filtered fluid under the motivation of a simultaneously applied positive or negative pressure to the sheet. The sheet is affixed to the elastic support in a ballooned state at one or several discrete locations so as to allow transfer of fluid through the sheet while keeping solids outside the seal. The invention also pertains to a method of filtration using the above device to provide autogenous cleaning by alternating the elastic support from a slack and ballooned state during the course of filtration so as to discharge accumulated solids from the surface of the sheet.

摘要： The present invention provides an apparatus including: a filter medium having a slack state and a ballooned state and an elastic support attached to the filter medium to define a contiguous fluid flow path through the filter medium and the support. The elastic support is adapted to displace the filter medium repeatedly between the slack state and the ballooned state; the ballooned state is out-of-plane with respect to the slack state; and the slack state of the filter medium provides for areal strain greater than about 10% of the ballooned state. A method of cleaning a filter medium in a flow path of a fluid containing a suspended component is also described.

摘要： A check valve for down-hole drilling applications may include a housing having a vent port and a chamber within the housing. The check valve may include a displaceable member within the chamber of the housing. An expanded polytetrafluoroethylene (ePTFE) membrane may be disposed over the vent port to protect the check valve from corrosion.

摘要： It has been discovered that the function of a fuel filter monitor can be accomplished without the use of SAP. The present invention provides a fuel filter monitor comprising an ePTFE membrane, a support structure adjacent to said ePTFE membrane wherein the membrane is disposed upstream of the support and said monitor prevents penetration of water to the downstream of said fuel wet monitor, where the water can be in the form of discrete water drops in the fuel, or a bulk water stream which displaces the upstream fuel.
