Publication number: 20120325084Abstract: Electrostatic aerosol in vitro exposure systems and methods are disclosed and can be used for collecting and depositing particulate matter onto tissue without pre-concentration, and without any intermediate collection steps such as use in water or on a filter. The system can include an inlet configured to receive air containing particulate matter, a receptacle configured to hold one or more tissue samples, a porous membrane providing support for an air-liquid interface of the tissue sample, and an electrostatic precipitation area. 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.Type: ApplicationFiled: July 26, 2012Publication date: December 27, 2012Inventors: Kenneth G. Sexton, Harvey E. Jeffries, Ilona Jaspers, David H. Leith, Glenn W. Walters, Melanie Lynn Doyle-Eisele, Kim M. Lichtveld, Sandra W. Irwin, James J. Jetter, Seth M.

Publication number: 20120291627Abstract: 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.Type: ApplicationFiled: January 5, 2011Publication date: November 22, 2012Applicant: ADVANCED TECHNOLOGY MATERIALS, INC.Inventors: Glenn M. Tom, Joseph Patrick Menning, Matthew Kusz, Amy Koland, Donald D. Ware, Richard D. Chism

Patent number: 8313555Abstract: 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.Type: GrantFiled: November 20, 2009Date of Patent: November 20, 2012Assignee: Allied Environmental Solutions, Inc.Inventor: Paul E. Petty

Publication number: 20120247324Abstract: 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.Type: ApplicationFiled: March 29, 2012Publication date: October 4, 2012Inventors: Dustin Kramer, David Williams, Sterling Imfeld

Publication number: 20120141352Abstract: 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.Type: ApplicationFiled: December 7, 2011Publication date: June 7, 2012Inventors: Jerry Lang, David Scott

Publication number: 20120118143Abstract: 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.Type: ApplicationFiled: November 17, 2010Publication date: May 17, 2012Inventor: Ronald E. Foreman

Publication number: 20120085231Abstract: 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.Type: ApplicationFiled: October 7, 2010Publication date: April 12, 2012Inventors: Dan Allan Robert Kristensson, Päl Martin Svensson, Niklas Sonden
