  • Patent number: 8337598
    Abstract: A thin film composite membrane comprises a core layer and a sheath UV-crosslinked polymer layer. The thin film composite membrane is produced by the co-extrusion of two polymer solutions. The core layer and the sheath layer can be separately optimized. The sheath layer may be UV-crosslinked to provide stability and selectivity at the desired operating temperature of the composite membrane.

  • Patent number: 7905259
    Abstract: An onboard inert gas generation system includes an evaporator comprising a vessel that receives a hydrocarbon fuel from a fuel tank, separates vapor fuel components from liquid fuel components, establishes a nearly constant fuel vapor composition, and outputs the fuel vapor to be mixed with air prior to combusting the fuel vapor and air mixture in a catalytic reactor. Water is separated from the inert gas produced and the inert gas is introduced into the ullage space of the fuel tank to prevent or reduce possible hazardous conditions in the fuel tank.

  • Patent number: 7671325
    Abstract: A biological agent detector for detecting predetermined biological agents. The biological agent detector includes an optical fiber, a cladding that clads a length of the optical fiber and a bioindicator disposed within the cladding. The biological agent detector also includes a coherent light source that excites the optical fiber and a biological agent signature detector that detects the presence of a biological agent based upon a change in a resonance characteristic of the optical fiber caused by absorption of the predetermined biological agent into the cladding of the fiber.

  • Patent number: 7628965
    Abstract: A gas generating system comprises a catalytic reactor in fluid communication with a sulfur separator. The catalytic reactor oxidizes a fuel to provide a supply of carbon dioxide. The sulfur separator removes sulfur components from the stream before or after the fuel is oxidized. A portion of the hot exhaust gas from the catalytic reactor can be used to regenerate an adsorption bed of the sulfur separator.

  • Publication number: 20040158108
    Abstract: The invention provides a process for the purification of alcohols, particularly for the purification of isopropyl alcohol. A invention provides a process for reducing the amount of ultraviolet light absorbing ketone impurities and/or aldehyde impurities in a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, which comprises reacting a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, with a sufficient amount of a reducing agent, under conditions wherein the reducing agent is preferentially more reactive with the ketone impurities and/or aldehyde impurities than the alcohol to thereby form a reaction product; and then recovering a recovered alcohol product from the reaction product.

  • Patent number: 6623550
    Abstract: A robust, relatively simple air quality control system that can control the air quality in buildings during both the heating and cooling seasons. In one illustrative embodiment, a first air stream is directed through an air treatment module and back into the inside space. A desiccant in the air treatment module adsorbs water, volatile organic compounds and/or particulate material from the first air stream. A second air stream is then directed through the air treatment module to a location outside of the inside space. The second air stream is preferably heated relative to the first air stream so that at least a portion of the adsorbed water, volatile organic compounds and/or particulate material are desorbed from the desiccant into the second air stream. The second air stream carries the desorbed water, volatile organic compounds and/or particulate material to a location outside the inside space.
