  • Patent number: 10371246
    Abstract: A breather vent assembly includes a vent main body defining an internal vent passage and including a proximal end, a distal end, and an upwardly extending retainer portion disposed outward of the distal end. A cap is coupled to the vent main body and disposed at the distal end. A tortuous path is defined between the vent main body and the cap and a fluid vapor flows through the internal vent passage and the tortuous path to thereby vent the fluid vapor from a transmission. A reservoir is defined between the distal end and the upwardly extending retainer portion and configured to receive a condensate when a portion of the fluid vapor condenses in the tortuous path. A drain passage extends through the vent main body and fluidly couples the reservoir and the internal vent passage such that the condensate in the reservoir is drained back to the vehicle transmission.

  • Patent number: 9028595
    Abstract: A process for separating methane from a natural gas mixture employs pressure swing adsorption in one or more vessels. Each vessel has an adsorbent material having a kinetic selectivity for contaminants over methane greater than 5. Contaminants within the natural gas mixture become gases kinetically adsorbed within the adsorbent material. The vessel is placed under pressure to cause contaminants to be adsorbed in the surfaces and micro-pores of the adsorbent material. The process includes releasing a product stream comprised at least 95% by volume methane from a first gas outlet in the vessel, and desorbing the contaminant gases from the adsorbent material by reducing the pressure within the vessel. The desorbing step is done without applying heat to the vessel, thereby delivering a waste gas stream comprised at least 95% by volume of the contaminant gases. An improved fractionation vessel having both major and minor flow channels is also provided.

  • Patent number: 9017462
    Abstract: Improvements in a filter where the filter self-expands based upon increased pressure or vacuum in the filtering stream. The expandable filter is adaptable to filtering a wide variety of media including air used in HVAC units, gases that are used to filter impurities out of gases and for industrial applications. The expandable filter to maintain a constant pressure or vacuum in the plenum or filter. The filter self-expands as the pressure or vacuum increases and pushes, pulls or draws the filter into an elongated or heightened configuration. As the filter expands new filter material is exposed that was not previously exposed for filtering. Expansion doubles, triples, or further increases the filter collection surface area. The filter does not rely upon gravity and expands based upon the increase of pressure or vacuum in the plenum the filter can be arranged in a vertical or horizontal orientation.

    Abstract: A method of operating a mass spectrometer vacuum interface comprising a skimmer apparatus having a skimmer aperture and downstream ion extraction optics. An expanding plasma is skimmed through the skimmer aperture. Within the skimmer apparatus, a portion of the skimmed plasma adjacent the skimmer apparatus is separated from the remainder of the skimmed plasma by providing means to prevent, inhibit or impede, the separated portion from reaching the extraction optics while allowing the remainder to expand towards the extraction optics. This allows removal of ions liberated from deposition matter on the skimmer apparatus surface, thereby discriminating against such ions, and offering reduced memory effects. The remainder of the plasma can expand towards the extraction optics, so interaction and mixing between the boundary layer and the remainder of the plasma can be reduced or minimized.

In one embodiment, an adsorption vessel for receiving a fluid mixture and for separating a component from therein includes a vessel wall extending from a bottom end to a top end and defining a vessel chamber. A bottom inlet is formed in the bottom end of the adsorption vessel for introducing the fluid mixture to the vessel chamber. Further, a support plate is positioned in the vessel chamber above the bottom end, and defines a bottom void volume between the support plate and the bottom end. A filler material having a total porosity of less than about 25% is positioned in the bottom void volume and defines a channel for flow of the fluid mixture from the bottom inlet to the support plate.

  • Patent number: 8453474
    Abstract: A vehicle air handling system includes an air handler, a desiccant assembly and a regeneration mechanism. The air handler has an air inlet configured to receive airflow into the air handler and an air outlet configured to direct the airflow from the air handler to a passenger compartment of a vehicle. The desiccant assembly is installed in a fixed non-movable orientation within the air handler. The desiccant assembly is configured to absorb moisture from the airflow and is disposed between the air inlet and the air outlet. The desiccant assembly includes a first flow path and a second flow path separated from one another such that the airflow passes through the first flow path. The regeneration mechanism is in fluid communication with the second air flow path of the desiccant assembly and is configured to remove moisture from the airflow passing through the desiccant assembly.

  • Patent number: 8388745
    Abstract: A sieve module includes an impermeable housing and an adsorptive media bed. The impermeable housing is puncturable at a first puncture location to receive gas from an exterior of the impermeable housing. The impermeable housing is also puncturable at a second puncture location to expel gas to the exterior of the impermeable housing. The adsorptive media bed is disposed within the impermeable housing. The gas flows through the impermeable housing from the first puncture wound to the second puncture location by flowing through the adsorptive media bed.

  • Publication number: 20120304629
    Abstract: An adsorption unit for combustion gas of an internal combustion engine has an adsorption housing having a chamber section with an inner wall. An adsorption element disposed in the adsorption housing is made of a gas-permeable adsorption medium that is formed to a hollow body and encloses an interior of the adsorption element. The hollow body has opposed open ends. A main flow passage extends through the hollow body and the combustion gas flows in main flow direction through the hollow body. The adsorption element has an exterior circumferential side facing away from the interior and delimiting together with the inner wall of the chamber section a bypass chamber surrounding the absorption element outwardly. In the main flow direction, the bypass chamber has a downstream end that is closed off and an upstream end that has at least one bypass opening that communicates with the main flow passage.
