Patent number: 7201878Abstract: Aerosol particle analyzer (APA) for measuring an analyte in airborne particle is described. Airborne particles are first given an electrical charge and then drawn in air past an oppositely charged volume of an analysis liquid that exposed to the air at a small hole in a container, such as a capillary, that holds that analysis liquid. Electrostatic forces enhance the rate that the airborne particles collide with the small exposed volume of the analysis liquid in the hole. If the particles that collide with the analysis liquid contain the analyte, an optical property of the analysis liquid, such as the fluorescence, varies according to the amount of the analyte in the particles. This optical property is measured and the amount of analyte in the particles is determined from the measured optical property.Type: GrantFiled: March 26, 2004Date of Patent: April 10, 2007Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Horn-Bond Lin, Steven Clyde Hill

Patent number: 7201879Abstract: An aerosol-into-liquid collector (ALC) for collecting gas-borne particles from a large volume of gas such as air into a small volume of liquid is described. The ALC uses a linear quadrupole to concentrate particles flowing in a gas and to help direct these concentrated particles toward a small volume of collection liquid so that these particles tend to combine with a small volume of collection liquid that can then be drawn from the ACL for further analysis. The particles in the gas are typically given a charge that is opposite to that of the charge imparted to the volume of collection liquid so that electrostatic forces help draw particles from the flowing gas into the small volume of liquid. The linear quadrupole focuses toward it axis particles that have the charge, mass and mobility to be stable in the linear quadrupole.Type: GrantFiled: November 19, 2004Date of Patent: April 10, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Steven Clyde Hill, Horn-Bond Lin

In using it, the desired sample amount to be transferred is determined by the flat recess of the sample pick-up surface and can be reproduced very precisely.Type: GrantFiled: March 17, 2000Date of Patent: April 10, 2007Assignee: F.

Patent number: 7201882Abstract: In the field of transformation of material there is a device for producing a plasma, a method for ionizing material using the device, uses of the inventive method and production processes using the device. The device includes a resonant chamber, an acoustic chamber provided with an acoustic device and a soliton chamber for receiving the treated material coming from the resonant chamber while simultaneously generating a recycling of outside air. The soliton chamber defines, with a pulsating suction member adjacent to the output of the soliton chamber, a space producing ionized material.Type: GrantFiled: September 20, 2001Date of Patent: April 10, 2007Assignee: Clarq International (Societe Civile)Inventor: Valentin Cesa

Patent number: 7201883Abstract: A catalytic reactor comprises a plurality of sheets defining flow channels between them. Within each flow channel is a foil of corrugated material whose surfaces are coated with catalytic material. Flow channels for a first gas extend in oblique directions relative to the flow channels for a second gas. The reactor incorporates header chambers to supply gas mixtures to the flow channels, the headers communicating with adjacent channels being separate. The reactor enables different gas mixtures to be supplied to adjacent channels, which may be at different pressures, and the corresponding chemical reactions are also different. Where one of the reactions is endothermic while the other reaction is exothermic, heat is transferred through the sheets separating the endothermic reaction. When the catalyst in one set of flow channels becomes spent, it can be replaced by removing a header.Type: GrantFiled: September 12, 2002Date of Patent: April 10, 2007Assignee: Compactgtl PLCInventors: Michael Joseph Bowe, Clive Derek Lee-Tuffnell

Patent number: 7201885Abstract: Methods for the removal of lead from a metal silicate during the process of manufacturing of such a material are provided. With the reliance upon lower cost starting silicon dioxide starting materials that are known to exhibit elevated amounts of heavy metal therein for the purpose of producing metal silicates (such as sodium silicate, as one example), it has been realized that removal of significant amounts of such heavy metals is necessary to comply with certain regulatory requirements in order to provide a finished material that exhibits the same low level of heavy metal contamination as compared with finished materials that are made from more expensive, purer starting silicon dioxides. Two general methods may be followed for such decontamination purposes. One entails the introduction of a calcium phosphate material, such as dicalcium phosphate, tricalcium phosphate, and/or hydroxyapatite, to a formed metal silicate solution but prior to filtering.Type: GrantFiled: November 17, 2005Date of Patent: April 10, 2007Assignee: J.M. Huber CorporationInventors: Yung-Hui Huang, John V. Offidani

Patent number: 7201888Abstract: The present invention provides silver oxide particles having an average diameter of less than or equal to 100 nm that are stable and can be transported in dry powder form. The surface of the silver oxide particles is coated with an extremely thin layer of a surfactant such as fatty acid. Nanosized silver oxide particles according to the invention are preferably formed via the addition of a strong base to a mixture including an aqueous silver salt solution and a surfactant dissolved in an organic solvent that is at least partially water miscible. The strong base causes silver oxide to precipitate from the mixture as nanosized particles, which are immediately encapsulated by the surfactant and thus protected from further crystal growth and Ostwald ripening. The nanosized surfactant coated particles of silver oxide can be washed and dried and then transported in dry form.Type: GrantFiled: October 7, 2003Date of Patent: April 10, 2007Assignee: Ferro CorporationInventors: Gregory M. Berube, Gargi Banerjee
