  • Publication number: 20090031898
    Abstract: A hydrocarbon adsorption unit for recovery of volatile hydrocarbons which emanate from several sources and which would otherwise be released into the atmosphere through the air cleaner of an automobile engine when the engine is shut-off. The unit is positioned in the air intake system such that all air flowing through the engine passes through the unit. The unit comprises a housing having an air inlet and an air outlet. The housing contains a substrate and a volatile hydrocarbon adsorber material coated on the surface of the substrate. The adsorber material may be silica gel, a molecular sieve and/or activated carbon. The material further contains a binder that will cause the material to adhere to the surface of the substrate.

  • Publication number: 20070107701
    Abstract: The present invention is directed to the use of an improved hydrocarbon adsorbent coating for the treatment of evaporative emissions from a motor vehicle. More specifically, one or more hydrocarbon adsorbents, in accordance with the present invention, can be coated to any surface area of an air intake system to trap hydrocarbon vapors before they can escape to the atmosphere, through said air intake system. In another embodiment, one or more hydrocarbon adsorbents can be incorporated in the air filter of an air intake system.

  • Publication number: 20070107599
    Abstract: The present invention is directed to an improved hydrocarbon adsorbent slurry washcoat formulation, which can be used for controlling evaporative hydrocarbon emissions from a motor vehicle. More specifically, the present invention is directed to an improved slurry composition of the present invention comprises one or more hydrocarbon adsorbent materials, and an organic polymer binder containing an anionic dispersant and/or stabilizing pH. The binder is used to improve the adhesion of the hydrocarbon adsorbent to the surface of the fuel storage, fuel delivery, or air intake system component.

  • Patent number: 5987207
    Abstract: The fiber organizer includes a tray for supporting at least one optical fiber within a housing, such as an optical receiver node. The fiber organizer also includes means for defining a raceway along which the optical fiber is routed. The raceway can be defined by inner and outer walls which extend outwardly from the tray in order to guide the optical fiber along the raceway in a manner which prevents the fiber from being excessively bent. In order to provide access to components disposed beneath the fiber organizer, the tray can include a hinge to permit a first portion of the tray to be pivoted relative to a second portion of the tray. The tray can also define one or more openings aligned with respective test ports of the electrical circuitry which lies beneath the fiber organizer. A technician can therefore establish electrical contact with the test ports while the tray remains in position within the housing.
