Abstract: A filter-less regulator is implemented for use in fluid flow systems that process low concentration reactive gases. The regulator includes an inlet, an outlet and a fluid flow path defined between the inlet and outlet by internal surfaces of the housing. The regulator further includes a pressure regulating section to reduce the pressure of a reactive gas flowing through the regulator between the housing inlet and the housing outlet. The internal surfaces of the housing are formed of a suitable material and the combined area of the internal surfaces is sufficiently sized to facilitate use of the regulator in the system without prior passivation for reactive gases at low concentrations (e.g., in the range of about 10 ppm or lower) while minimizing or substantially preventing significant loss of the reactive gas due to reaction and/or adsorption within the regulator.

Abstract: A security access method for a multifunctional device, that includes receiving login information from a user, contacting a directory, receiving personal security level information about the user from the database, and generating a customized user interface for the user based upon the user's security level.

Abstract: A security method for a multifunctional device. The method includes receiving a document, wherein the document has an associated security level, determining what services may be used with respect to the document, based upon the security level of the document, and generating a customized user interface that does not display any services that may not be used with the document. Further, the device may receive personally identifying information from a user including the user's security level, and deciding what services may be used with respect to the document is based at least in part upon the user's security level.

Abstract: Methods of cleaning metal containers, and containers having internal metal linings are described. The methods comprise the steps of exposing the internal metallic surface to a composition comprising ozone, the internal metallic surface having thereon a residue, contacting the composition comprising ozone with the internal metallic surface for a time sufficient to either remove the residue, chemically modify the residue to form a modified residue that may be removed by other means, or deactivate the residue.
