Reduction Of Pressure During Liquid Contact Patents (Class 95/201)
  • Patent number: 10913087
    Abstract: Embodiments of a system and a method for preparing mold-resistant paper comprising a wet scrubber assembly in fluid communication with at least one collection plenum disposed at an operational area of a paper manufacturing line. The wet scrubber assembly can be operated to draw a stream of exhaust air from the operational area of the paper manufacturing line through the wet scrubber assembly to remove particulate from the exhaust stream. Such systems and methods can be used to produce mold-resistant paper by coating a paper with an antimicrobial composition including at least one antimicrobial additive at the calendering stage. The collection plenum can be placed in proximate relationship with the calendering stack such that the amount of antimicrobial additive particulate in the air at the calendering stage is reduced. The mold-resistant paper can be used in a gypsum panel.

  • Patent number: 7972489
    Abstract: A sensor element is used to detect a physical property of a measuring gas, preferably to determine the oxygen content or the temperature of an exhaust gas of an internal combustion engine. The sensor element contains a first solid electrolyte layer and a second solid electrolyte layer. A first printed conductor and a second printed conductor are provided on opposite sides of the first solid electrolyte layer, the first printed conductor including a first electrode and a feed line to the first electrode, and the second printed conductor including a second electrode and a feed line to the second electrode. A third printed conductor, which includes a third electrode and a feed line to the third electrode, is provided on the second solid electrolyte layer. The second printed conductor is positioned between the third electrode and the first printed conductor.

  • Publication number: 20090211447
    Abstract: A process for the recovery of carbon dioxide, which includes: (a) an absorption step of bringing a carbon dioxide-containing gaseous feed stream into gas-liquid contact with an absorbing fluid, whereby at least a portion of the carbon dioxide present in the gaseous stream is absorbed into the absorbing fluid to produce (i) a refined gaseous stream having a reduced carbon dioxide content and (ii) an carbon dioxide-rich absorbing fluid; and (b) a regeneration step of treating the carbon dioxide-rich absorbing fluid at a pressure of greater than 3 bar (absolute pressure) so as to liberate carbon dioxide and regenerate a carbon dioxide-lean absorbing fluid which is recycled for use in the absorption step, in which the absorbing fluid is an aqueous amine solution containing a tertiary aliphatic alkanol amine and an effective amount of a carbon dioxide absorption promoter, the tertiary aliphatic alkanol amine showing little decomposition under specified conditions of temperature and pressure under co-existence with

  • Patent number: 6837919
    Abstract: According to the present invention, electrorheological fluid is deaerated after it is sealed in a closed device which is operated by the electrorheological fluid. Thus, it is possible to control the operation of the closed device in accordance with an electric field. Additionally, the control of viscosity is not affected by repetitive operations of the closed device, thereby obtaining a closed device having a smooth operation and good repeatability. The deaeration is achieved under a predetermined reduced pressure, for example, of not more than 100 torr. In addition thereto, a suitable heating process is carried out as required.

  • Patent number: 5279646
    Abstract: A venturi scrubbing system optimized for removing the most optically active sized particles from a gaseous effluent stream is disclosed. Before entering the venturi the effluent stream is subcooled to cause condensation of water vapor and other condensibles, thereby greatly reducing the volume of the effluent stream. In the venturi stage a scrubbing liquid is added in the form of droplets having a median diameter which is optimized to remove the optically active particles. Preferably, the median diameter of the scrubbing liquid droplets is between 10 and 200 microns. A two-fluid nozzle may be used to efficiently form the droplets. After passing through the scrubbing stage, which may also comprise one or more impingement plates, the cleansed effluent may be passed through an afterburner to remove combustible materials such as organic vapors.
