  • Patent number: 9364797
    Abstract: The present invention relates to the production of high flux hollow fiber ultrafiltration membrane prepared from poly(acrylonitrile-co-methacrylic acid), (polysulfone and poly(acrylonitrile-co-methacrylic acid)) and (polysulfone and ion exchange resin (sulfonated polystyrene-divinyl benzene copolymer)) blend and the point-of-use filtration unit there from for water purification and disinfection. The produced membrane has an active layer with pore size which effectively rejects pathogens and other bacteria from contaminated water while allowing the passage of water to produce biologically pure water for drinking. Therefore, the present invention relates to development of hollow fiber ultrafiltration membrane that delivers biologically pure water at a desirable rate, that is at a rate 25-200 liters/m2.h. The membrane performance in terms of flux and rejection efficiency is dependent on polymer material type and surface properties.

  • Patent number: 9365749
    Abstract: Illustrative embodiments of an anisotropic conductive adhesive (ACA) configured to be cured after being subjected to a magnetic field are disclosed. In at least one illustrative embodiment, the ACA may comprise a binder and a plurality of particles suspended in the binder. Each of the plurality of particles may comprise a ferromagnetic material coated with a layer of electrically conductive material and with a moisture barrier, such that the electrically conducting material forms electrically conductive and isolated parallel paths when the ACA is cured after being subjected to the magnetic field.

  • Patent number: 9284447
    Abstract: Silanes of formula (I): or inorganic fillers whose surface is coated or derivatized with a silane of formula (I), are curing agents for epoxy resins that are activatable at elevated temperature. The thermosetting epoxy resin compositions allow a large reduction in the curing temperature without great impairment of their storage stability. They are therefore very well suited for single-component thermosetting epoxy adhesives, which in particular may contain impact modifiers.

    Abstract: An epoxy resin composition is disclosed for joining dissimilar materials. The identified epoxy resin compositions can be used to seal metallic and non-metallic components of a capacitor. Specifically the epoxy resin composition can be applied to joints between a non-metallic capacitor bushing and a metallic tank cover and metallic terminal cap. Once the epoxy resin composition is cured, it can provide a seal that can withstand the stresses and environmental conditions to which a capacitor is subjected.
