Particulate matter contained in the air received at the inlet can be electrically charged in the electrostatic precipitation area and flowed over the tissue sample, where it can be collected and measured.

  • Publication number: 20120291627
    Abstract: A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel. Presence of fluid or change in phase of flowing fluid within a fluid circuit may be sensed by comparing outputs of first and second temperature sensing elements, with one sensing element including a heater to increase temperature of the sensing element in exposure to gas but not in exposure to liquid.

  • Patent number: 8313555
    Abstract: A method and system for automated control of the operating temperature setpoint of a circulating fluidized bed (CFB) scrubber within a pre-determined range of approach temperatures to the adiabatic saturation temperature of the CFB scrubber exhaust stream to maintain an optimal operating temperature, thereby reducing low temperature sulfuric acid corrosion and deposition of wet materials, and high temperature excess reagent use. A Dewcon® Moisture Analyzer (or equivalent) is connected in the exhaust stream of the CFB scrubber. The Dewcon® Moisture Analyzer transmits adiabatic saturation temperature data of the exhaust stream to the CFB scrubber system controller. Based on pre-programmed parameters, the system controller adjusts the CFB scrubber temperature setpoint.

  • Publication number: 20120247324
    Abstract: A fluid degasification system for a hydraulic circuit includes a gas/fluid separation tank, a fluid entry passage directing fluid into a small foam generating cup containing foam and a small amount of additional fluid, thereby stimulating foam formation. A separation screen is positioned below the foam generating cup to receive bubbles formed in the cup and to allow liquid to pass through the screen to a degasified-fluid collecting chamber below the screen as the bubbles resting on the separation screen decompose.

  • Publication number: 20120141352
    Abstract: High molecular weight (HMW) gases are separated from an exhaust gas of a combustion source using a blower and an interior vent within the exhaust stack. The interior vent includes a vent wall having a top portion attached to the interior surface of the exhaust stack along the entire inner perimeter of the exhaust stack and a lower portion that extends downward into the exhaust stack to form an annular space or gap between the vent wall and the interior surface of the exhaust stack, and at least one opening in the interior surface of the exhaust stack between the top and bottom portions of the vent wall. The blower creates a tangential flow of the exhaust gas with sufficient centrifugal force to concentrate substantially all of the HMW gases along the inner surface of the exhaust stack. A transfer pipe removes the HMW gases from the interior vent.

    Abstract: An apparatus and method for dehumidifying a desired area using a desiccant dehumidifier. The desiccant dehumidifier of the present invention provides substantial advantages over known desiccant dehumidifiers in terms of simplified manufacture and improved efficiency. The dehumidifier of the present invention includes a single chamber with an intake and an exhaust end, a desiccant, a fan and a heater located in the chamber, and one or more regulators for directing intake and/or output of air in relation to the chamber. This configuration does not require a rotor motor or cycling multichamber apparatus in order to change operation of the apparatus from drying air to reactivating the desiccant.

    Abstract: Methods and devices are provided whereby a controlled personal breathing zone is maintained using temperature controlled laminar air flow (TLA) of filtered air. A substantially laminar, descending flow of filtered air is maintained with a velocity determined by the air-temperature difference between the supplied air and the ambient air at the level of the personal breathing zone. The air-temperature of the filtered supply air can be carefully adjusted to maintain the velocity-determining difference in air-temperature within the optimum range of 0.3 to 1° C. Thus being able to at the same time displace body convection and achieve comfort.

  • Publication number: 20120067205
    Abstract: In a compressed air purification apparatus for motor vehicles, compressed air under static pressure in a pressure conduit (3) is firstly freed of impurities such as hydrocarbon compounds and oil products and subsequently dried. To ensure effective freeing of the compressed air of impurities and water vapour and provide a compressed air purification apparatus which can be used with simple means in motor vehicles, the invention provides for the compressed air being brought, before purification, to such a temperature that the gaseous impurities in the compressed air are condensed and the water present in the compressed air is dissolved as vapour.

  • Patent number: 8128728
    Abstract: A system and process for gas homogenization is disclosed. This has application in the areas of generation of gas and its conversion to electricity in downstream applications. The homogenization system minimizes variance in the gas characteristics (composition, flow, pressure, temperature), thereby rendering a steady stream of gas of consistent quality to the downstream machinery. This homogenization system can be adjusted to optimize the output gas stream for specific end-applications, or to optimize the output gas stream for different input feedstocks. This ensures that overall conversion efficiencies are maximized while keeping the process cost-effective. Such a uniform, steady output gas stream has a wide range of applications in the broad areas of generation of electricity (e.g. using internal combustion engines and combustion turbine engines), chemical synthesis (e.g.
