摘要： A probe is provided that combines in one housing a pressure regulator and filter/dryer element. The probe may be connected to a conduit for the transfer of a fluid sample, such as natural gas, from the conduit to provide separation of the fluid such that a gaseous component may be then subsequently transferred to an instrument or the like. If liquid is separated it may be returned to the conduit via a return line.

摘要： A composite membrane and method for making the same, comprising a porous support and a crosslinked polyamide surface. The subject membrane provides improved flux and/or rejection rates. The subject membrane is further capable of operating at lower operating pressures. The subject method includes reacting a polyfunctional amine with a polyfunctional acyl halide to form a polyamide. The method includes the step of contacting a phosphorous containing compound with the polyfunctional acyl halide prior to and/or during the reaction between the polyfunctional acyl halide and a polyfunctional amine. The subject process is easily adapted to commercial scale manufacturing processes and is particularly suited for making nanofiltration and reverse osmosis composite membranes.

摘要： A filter element assembly has at least two cylindrically shaped and concentrically arranged filter media sleeves each connected at one end thereof to an inlet plate and each connected at the other end to a closed end terminal plate. Openings are provided in the inlet plate to permit entry of liquid to be filtered into the annular space between the filter sleeves. The closed end terminal plate prevents flow of unfiltered liquid from the annular space between the sleeves so as to force the liquid through the porous media of the sleeves to effect filtration. The inlet plate includes a central area that is recessed in relation to its outer edge to define an inlet chamber capped by a planar housing lid. The inlet chamber communicates with the inlet conduit via an opening in the central area.

摘要： A porous thermoplastic resin film capable of functioning well as a separator of a cell is provided. The porous film is constituted with a thermoplastic resin and a filler, wherein XR defined by the following formula: XR=25×TGUR×d2/Y is smaller than 5, where Y(&mgr;m), TGUR (sec/100 cc), and d (&mgr;m) represent the thickness, the gurley value, and the average pore diameter of said film, respectively. The porous film constructed as shown above can reduce the internal resistance of a cell when used as a separator of the cell.

摘要： A filter element assembly includes two cylindrically shaped and concentrically arranged flexible media sleeves (302, 301), wherein the sleeves are respectively supported against radial flow by an inner and outer cage (325, 330). Respective ends of the sleeves are permanently affixed to an inlet plate 303 and a terminal plate 304. The inlet plate includes a closed central area 315 to prevent unfiltered liquid from entering the cylindrical space 306 defined by the inner filter sleeve. The inlet plate also includes openings 316 to allow unfiltered liquid into the annular space 305 between the sleeves. An end cap 340 is permanently affixed to the inlet plate and includes a support on an upper surface thereof for supporting the assembly within a housing.

摘要： A composite polyamide reverse osmosis membrane and method of producing same. In one embodiment, the membrane is made by coating a porous polysulfone support for about 40 seconds with an aqueous solution containing (i) a polyfunctional amine in the form of 2 wt % of meta-phenylenediamine (MPD), (ii) a polar solvent in the form of 0.3 wt % 2-ethyl-1,3-hexanediol (EHD), and (iii) an amine salt-forming combination of 2.3 wt % camphorsulfonic acid (CSA) and 1.1 wt % triethylamine (TEA). Next, the excess aqueous solution is removed, and the coated support is dipped for about 1 minute in a 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the organic solvent solution off, the resulting composite membrane is heated at 90° C. for about 3.5 minutes and then rinsed in a 0.2% Na2CO3 aqueous solution at room temperature. The resultant membrane exhibits a flux of 47.9 gfd and a salt rejection of 97.6% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl. In another embodiment, the aqueous solution contains (i) a polyfunctional amine in the form of 2 wt % of MPD, (ii) a combination of polar solvents in the form of 0.3 wt % of EHD and 2 wt % of dimethyl sulfoxide, and (iii) an amine salt-forming combination of 1 wt % of 1,1,3,3-tetramethylguanidine and 1.6 wt % toluene sulfonic acid. The resultant membrane exhibits a flux of 63.7 gfd and a salt rejection of 90.8% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.

摘要： A filter material includes a filter pad made from a thin, nonwoven fiber mat which has been accordion-pleated, compressed into a unit having a large number of substantially parallel interconnected filter strips, and treated to retain the filter strips in substantially parallel relation to each other. In a preferred embodiment, activated carbon particles are operatively associated with the filter pad. Selected fibers of the nonwoven fiber material are hollow fibers, each having an outer surface, a hollow internal cavity, and an extended slot formed therein, between the hollow internal cavity and the outer fiber surface. Carbon particles may be located between selected filter strips, and additional carbon particles may be disposed within the cavities of the hollow fibers. Methods of forming the filter material, and a filter element made with the filter material are also disclosed.
