The mist microencapsulates the biocide gas so that it does not decompose in the fumigation volume or space. The resulting homogenous mist solution provides a mist for delivering the biocide agent in a chemically stable form. Methods for mixing the separately generated mist and biocide gas include combining the mists in a Y-tube and then mixing the combination in a baffled mixing chamber, combining the mists in an area above their points of generation and then further mixing, and providing a series of mist generation units connected by a conduit for a carrier medium to pass to and connect the units and cause the mists to combine.Type: GrantFiled: May 2, 2003Date of Patent: September 4, 2007Assignee: Nanomist Systems, LLCInventors: Kayyani C.

Patent number: 7264778Abstract: Carbon monoxide sensors suitable for use in hydrogen feed streams and methods of use thereof are disclosed. The sensors are palladium metal/insulator/semiconductor (Pd-MIS) sensors which may possess a gate metal layer having uniform, Type 1, or non-uniform, Type 2, film morphology. Type 1 sensors display an increased sensor response in the presence of carbon monoxide while Type 2 sensors display a decreased response to carbon monoxide. The methods and sensors disclosed herein are particularly suitable for use in proton exchange membrane fuel cells (PEMFCs).Type: GrantFiled: March 12, 2003Date of Patent: September 4, 2007Assignee: Sandia CorporationInventors: Anthony H. McDaniel, J. Will Medlin, Robert J. Bastasz

Patent number: 7264781Abstract: Particulate material to be calcined is conditioned and then introduced into a stream of flue gases which transport the material along a sloping drying duct while drying the material. The dried material is then introduced into the same stream of flue gases upstream of the drying duct, and the flue gases transport the dried material along a sloping preheating duct while preheating the material. The preheated material is fed tangentially into the lower end of a vertical calcine reactor and calcined product is withdrawn tangentially from the upper end of the reactor. The flue gases used for drying and preheating are produced in the calcine reactor and are cooled during the drying and preheating.Type: GrantFiled: October 22, 2004Date of Patent: September 4, 2007Assignee: Pneumatic Processing Technologies, Inc.Inventor: Michael A. Jones
