Patent number: 10401264Abstract: The present invention discloses an efficient electrostatic particle-into-liquid sampler (EPILS). The EPILS collects an aerosol sample in the dry mode and extracts it in the wet mode to prevent sampling artifacts. In the dry mode, a first stage utilizes carbon brushes as discharge electrodes to charge aerosol particles which are then collected on the cylinder wall by the electric field setup between the high-voltage central metal rod and the grounded cylinder in the second stage. In the wet mode, DI water is injected into the EPILS in a pulsation manner by opening and closing solenoid valves intermittently, which dislodges aerosol particles deposited on the cylinder wall effectively to become a liquid aerosol sample. The liquid aerosol sample is then analyzed for chemical compositions manually or automatically.Type: GrantFiled: August 8, 2017Date of Patent: September 3, 2019Assignee: NATIONAL CHIAO TUNG UNIVERSITYInventors: Chuen-Jinn Tsai, Chao-Ting Hsu

More particularly, embodiments of the present invention provide a pair of concentric counter-rotating surfaces and a dividing member fixed radially therebetween so as to form a scanning chamber wherein sample particles are reoriented relative to the scanning field of an adjacent sensor device by the counter-rotation of the surfaces and the consequent recirculation of the sample particles through the scanning chamber.Type: GrantFiled: February 1, 2008Date of Patent: August 3, 2010Assignee: Pioneer Hi-Bred International, Inc.Inventors: Wilhelm G. Greten, Roland Welle

Patent number: 7718102Abstract: Foam for making pads and belts with controlled, reproducible microcellular structure and method of making such foam in a fast and efficient manner. Under constant pressure and temperature, a prepolymer is mixed with the nucleation surfactant in a tank in the presence of a frothing agent metered into the tank by way of a dip tube or sparge. The nitrogen gas is sheared into small bubbles and is drawn off from the headspace of the tank creating a continuous flow of nitrogen. The pressure of the tank may vary from any absolute pressure down to near complete vacuum, thereby all but eliminating the pressure requirement. The froth of the present invention has a more consistent cell structure and increased cell count.Type: GrantFiled: October 7, 2002Date of Patent: May 18, 2010Assignee: Praxair S.T. Technology, Inc.Inventors: Brian Lombardo, Jeffrey P. Otto

Patent number: 7645428Abstract: A reaction vessel which includes internally placed temperature controlling mixing baffles in which liquid is boiled, resulting in an isothermal heat sink. The energy of vaporization is supplied by the reaction vessel contents. The vapor produced by the boiling may be directed to channel coils which surround the outside of the reaction vessel wall. The channel coils contact the outside wall of the reaction vessel perpendicularly, and provide mechanical support for the reaction vessel. The mechanical support from the channel coils allows for a decrease in the thickness of the reaction vessel wall and corresponding increased heat transfer efficiency between the channel coil contents and the reaction vessel contents. The entire above described apparatus is enclosed within an evacuated shell to provide additional insulation.Type: GrantFiled: June 28, 2005Date of Patent: January 12, 2010Inventor: José P. Arencibia, Jr.

Publication number: 20090190433Abstract: An apparatus is disclosed for mixing salt with a liquid to generate a salt slurry for spreading on a road surface for snow and ice control. The apparatus includes a chute having an inlet and an outlet, the inlet receiving therein the salt. The chute defines a passageway which is disposed between the inlet and the outlet. A first roller is disposed adjacent to the outlet of the chute, the first roller having an axis of rotation and a first and a second end. A second roller has a first and second extremity, the second roller being disposed adjacent to the outlet of the chute. The second roller has a rotational axis which is disposed parallel to the axis of rotation of the first roller. The rollers cooperate with each other so that the chute guides the salt between the rollers. An arrangement is provided for rotating the rollers relative to each other such that when the salt is guided between the rotating rollers, crushing of the salt is permitted.Type: ApplicationFiled: November 10, 2008Publication date: July 30, 2009Inventor: Kevin J. Davis

Publication number: 20090026150Abstract: A method of and apparatus for mixing chemicals in a single wafer process. According to the present invention a chemical is fed into a valve system having a tube of a known volume. The chemical is fed into the valve system to fill the tube with a chemical to generate a measured amount of the chemical. The measured amount of chemical is then used in a single wafer process.Type: ApplicationFiled: September 17, 2008Publication date: January 29, 2009Inventors: Steven Verhaverbeke, J. Kelly Truman, Rick R. Endo, Alexander Ko

Publication number: 20090003123Abstract: An apparatus and method for mixing by producing shear and/or cavitation, and components for the apparatus are disclosed. In one embodiment, the apparatus includes a mixing and/or cavitation chamber with an element such as an orifice component that is located adjacent the entrance of the cavitation chamber. The apparatus may further include a blade, such as a knife-like blade, disposed inside the mixing and/or cavitation chamber opposite the orifice component. In one version of such an embodiment, at least some of the portions of the orifice component surrounding the orifice and/or the blade are made of a material or materials that have a Vickers hardness of greater than or equal to about 20 GPa. A process for mixing by producing shear and/or cavitation in a fluid is also contemplated herein.Type: ApplicationFiled: June 27, 2008Publication date: January 1, 2009Inventors: Lowen Robert Morrison, JR., Ke-Ming Quan, Raul Victorine Nunes, Vesselin Nikolov Shanov, Paul Alfred Cimiluca

Publication number: 20080148780Abstract: The invention relates to a method and to a device for homogenizing a glass melt in a melt receptacle, wherein at least one stirring device (10, 11) is disposed in the melt receptacle, which comprises a stirrer shaft (10) and a plurality of stirrer blades (11), and wherein a gap (16) is formed between a wall region of the melt receptacle (2) and the stirrer blades (11). According to the invention, the respective stirring device causes an axial feed action in an inner stirring region (12) between the stirrer shaft (10) and the stirrer blades (11) in order to feed the melt in the stirring region along the stirrer shaft (10). A melt flow brought about by the axial feed action seals the gap (16) against direct passage of the melt. According to the invention, a very high gap width can be achieved, thus preventing the abrasion of materials in the region of the marginal gap. This also reduces the complexity required for adjusting the device.Type: ApplicationFiled: December 17, 2007Publication date: June 26, 2008Inventors: Christoph Berndhaeuser, Frank-Thomas Lentes, Karin Naumann, Hans Duerolf, Holger Hunnius

Publication number: 20080080300Abstract: The invention relates to a mixing kneader comprising at least two shafts (2,3) configured as hollow shafts, on whose surfaces kneading bars (4) are disposed on elements (5). The construction of the shafts is selected in such a way that the resonant frequencies of the shafts have a separation of at least 5% from the excitation frequencies. At least one of the shafts is preferably flowed through by a temperature-control medium, the inlet being disposed on one side and the outlet on the other side of the shaft. The mixing kneader preferably comprises at least one orifice above the shafts which is configured as a dome, the dome being closed by a displacer (22).
