  • Patent number: 5186832
    Abstract: This invention provides spiral-wound hollow fiber membrane fabric-containing cartridges and modules for separations and other phase contact applications, in which the cartridges contain a turbulence-promoting fibrous web which is substantially-co-extensive to the fabric-like array, that induces turbulent fluid flow in the shell side of the hollow fiber membrane bundle; and methods for fabricating such cartridges.

  • Patent number: 5169529
    Abstract: Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules have a module case and bundle of a dense plurality of hollow fiber membranes contained in the case. One set of the fiber membranes in the bundle constitutes feed-fibers while another set of the fiber membranes in the bundle constitutes strip-fibers for use in contained liquid membrane separations. The feed-fibers and strip-fibers are disposed within the elongate module case in opposite generally wave-like paths such that the feed-fibers and strip-fibers converge at generally lengthwise-separated crossing regions within the module. This disposition of the feed-fibers and the strip-fibers minimizes the effective membrane thickness value of the module as compared to conventional contained liquid membrane modules thereby enhancing the efficacy of fluid separations.

  • Patent number: 5013439
    Abstract: Disclosed are a process for forming an open-celled microporous membrane (e.g., in film or fiber form) and a novel microporous membrane formed thereby. The process generally includes sequential cold and hot stretching operations, whereby the cold stretching operation is preferably accomplished in a plurality of discrete cold stretching steps. In this regard, the total cold stretch extension is of greater than about 30 percent, and advantageously greater than about 40 percent based upon the initial unstretched length of the nonporous precursor, with this total cold stretch ratio being distributed among a plurality of discrete cold stretching steps. The novel membranes of this invention are characterized by decreased pore size and increased pore densities. For example, the membranes of this invention will have an average pore radius as determined by mercury porosimetry of less than about 0.040 micron. The membranes of this invention, moreover, exhibit a distinctive "bluish" color hue (i.e., a Macbeth Coloreye.

  • Patent number: 4482748
    Abstract: The homogeneous catalysis of the hydrocarbonylation of olefins using a catalyst comprising a complex between an organic ligand and a Group VIII noble metal hydride carbonyl. The reaction is performed at mild conditions including temperatures from 50.degree.-200.degree. C. and pressures from 1 to 10,000 atmospheres to produce a predominantly aldehyde product having a high normal to iso distribution. The aldehyde products so produced are useful as intermediates for hydrogenation to aliphatic alcohols, for aldol condensation to produce plasticizers, for oxidation to produce aliphatic acids, etc.

  • Patent number: 4324588
    Abstract: This invention relates to an arc erosion-resistant composite material and methods for its manufacture and, more specifically, composite arc erosion resistant materials useful as electrodes in spark plug and jet engine igniters to promote longer useful life. An arc resistant material in particulate form is dispersed throughout a lower melting matrix metal clad in a tube of nickel or nickel alloy, and then worked to a very small outside diameter, after which the composite may be cut to provide electrode elements. Ruthenium and iridium, and their alloys comprise the arc erosion resistant material. Suitable matrix metals comprise silver, gold, copper, nickel, and palladium.

  • Patent number: 4293450
    Abstract: An electrically conductive composition is provided which comprises an intercalation compound of (1) graphite, (2) fluorosulfonic acid, chlorosulfonic acid, or mixtures thereof, and (3) a boron trihalide, a tetrahalide of a Group IV element, a pentahalide of a Group V element, or mixtures thereof. The graphite may be in any one of a variety of physical configurations, e.g. as particulate crystals or present in a carbonaceous fibrous material, at the time of the intercalation reaction. The resulting graphite intercalation compound possesses advantageous electrical conductivity characteristics not possessed by plain graphite and is capable of utilization as a light weight electrical conductor. The graphite intercalation compound may optionally be provided within a metal matrix (e.g. within elemental copper) to form an electrically conductive composite article.

  • Patent number: 4293469
    Abstract: The mold deposit problem commonly associated with non-reinforced polyoxymethylene molding compositions which creates a non-uniform surface on a molded article effectively is minimized. The polyoxymethylene polymer initially is heated (as described) while in admixture with about 0.25 to about 3 percent by weight based upon the weight of the polyoxymethylene polymer of a certain polycarbodiimide. The polycarbodiimide contains at least three carbodiimide units per polycarbodiimide molecule and is derived from one or more aromatic diisocyanates which are unsubstituted or are substituted with up to one methyl substituent on each aromatic ring.
