    摘要: An aluminum alloy contains at least about 0.01 to 0.2 weight percent gallium, at least about 0.01 to 0.2 weight percent tin, and at least about 0.01 to 0.2 weight percent lead. In another embodiment, the alloy may contain at least about 0.01 to 0.2 weight percent indium in lieu of the tin. The balance of both alloys is aluminum, tolerable levels of trace metals, and impurities. Preferably, the aluminum is present in 99.9% purity. The alloy can be used advantageously as an anode in an aluminum-air battery. The gallium-tin-lead aluminum alloy when used as an anode, is preferably used with a salt water electrolyte. The gallium-indium-lead alloy, when used as an anode is preferably used with a caustic electrolyte. The aluminum base alloy may be used as an anode in a battery assembly, a housing, an anode of the present invention, a cathode, and a support means within the housing to secure the anode and cathode in a relative spaced relationship.

    摘要: The present invention discloses a method and apparatus for continuous analysis of a gas and particulate stream. More particularly, the present invention provides a method and apparatus for continuously analyzing a gas and particulate exhaust stream comprising metal fluorides to determine the fluoride concentration of such stream. A sampling nozzle communicating with a sampling line is placed in a gas and particulate stream. A gas-dissolving solvent is injected into a portion of the stream in the inlet portion of the sampling nozzle forming an aerosol. This portion of the stream and aerosol form a mixture comprising aerosol, gas and particulate which flows through the outlet portion of the sampling nozzle and through the sampling line. The aerosol in the mixture impinges against the inner surface of the sampling line wetting such inner surface with solvent; such mixture is scrubbed in the sampling line to enhance dissolution of gas in the solvent. The solvent and particulate in such mixture are separated from undissolved waste gases in the mixture, and such separated solvent and particulate are transported to a continuous analysis means to determine the concentration of dissolved gas and particulate.
