Patent number: 7345097Abstract: An autoxidisable architectural coating composition suitable for application to surfaces found in and around buildings at ambient temperatures and in natural daylight by unsophisticated users having no respiratory protection wherein surface autoxidation of the composition is promoted by a combination of low concentrations of metal ions (especially manganese or vanadium) and at least one photoinitiator. The composition avoids the need to use more than trace amounts cobalt ions which are rumoured to be carcinogenic yet achieves adequately fast rates of autoxidation. Preferably the use of cobalt is avoided altogether. The use of the low concentrations of the other metal ions reduces discolouration of the compositions often to levels below what is achieved using conventional cobalt promoters. It also improves gloss. Also a modification in which surface autoxidation is promoted by a combination of a photoinitiator and trace amounts of cobalt ions in the absence of other surface autoxidation promoting metal ions.Type: GrantFiled: September 10, 2004Date of Patent: March 18, 2008Assignee: Imperial Chemical Industries PLCInventor: Philip Louis Taylor

Patent number: 7022509Abstract: A method for removing a gas from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the compound to be removed into the gas vesicles, and placing the gas vesicles such that the gas compound is removed from the site. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium—such as darkness, exponential growth stage, flocculation, or dissolved gas flotation—then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: May 10, 2002Date of Patent: April 4, 2006Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap
