Abstract: Apparatus and method for testing one or more sterilization indicators (e.g., biological indicators or chemical indicators) or other articles by contacting them under controlled sterilization conditions with a flowing antimicrobial gas containing hydrogen peroxide vapor are disclosed. This invention also provides apparatus and method for testing sterilization processes that use a flowing antimicrobial gas containing hydrogen peroxide vapor under controlled sterilization conditions, or for testing materials for such processes under controlled sterilization conditions, or for testing both such processes and such materials under controlled sterilization conditions. There can be an essentially square-wave contact of the sterilization indicators or other articles with the antimicrobial gas (i.e.

Abstract: Methods are disclosed for determining the monotonic functional relationship between (A) the integrated absorbance of spectral energy within a spectral region of interest of an analyte (i) that decomposes during the time experimental spectral data for determining the relationship are being obtained, or (ii) whose spectral data are pressure sensitive at pressures below a given pressure, or (iii) that decomposes during the time the spectral data are being obtained and whose spectral data are pressure sensitive and (B) the concentration of the analyte before decomposition commences. Methods are also disclosed for using the monotonic functional relationship to determine the concentration of the analyte in an unknown from the integrated absorbance of spectral energy within the spectral region of interest for the unknown.

Abstract: Apparatus and method for producing at high efficiency vaporization a precisely controllable, continuously adjustable gas-phase flow of a vaporizable liquid (e.g., hydrogen peroxide) in a carrier gas (e.g., air) are disclosed. The gas-phase product flow can be substantially continuous, low-temperature, unsaturated with respect to the vaporized vaporizable liquid, and of substantially constant vaporized vaporizable liquid concentration as a function of time. Fine particles of the vaporizable liquid are produced and introduced into the flow of carrier gas/vapor in a vaporization plenum with a sufficient flow of carrier gas/vapor to provide a curtain of carrier gas/vapor between substantially all of the fine particles of vaporizable liquid and the inner surface of the vaporization plenum.

Abstract: The degradation of organic electrode separators in rechargeable lithium-sulfur dioxide electrochemical cells which utilize chemically uncombined aluminum chloride as an electrolyte component can be reduced by incorporating an additive into the electrolyte which is effective to provide a redox couple having a potential in the range which is above that of the SO.sub.2 /S.sub.2 O.sub.4.sup.-2 couple and below that of the Cl.sub.2 /Cl.sup.- couple.

Abstract: A quinone imine dye can be used as an electrolyte additive in lithium-sulfur dioxide electrochemical cells to reduce the polarization which is observed during current flow conditions and, in some cases, to improve electrolyte stability and prevent or reduce the possibility of explosion upon abuse.
