Abstract: A scrubber for removing pollutants from a gas comprising a housing for conducting the gas therethrough, a mechanism for introducing pollutant-reactive filtering agent into the housing, a sump for collecting the filtering agent and having a first volume, and an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume.

Abstract: Apparatus for generating calibration gas comprising a contained stream of carrier gas, and a chamber containing at least part of the stream and a volatile reference liquid held by a wick structure so that as the stream passes through the chamber, the volatile reference liquid evaporates from the wick structure into a gas that blends into the carrier gas to form a calibration gas.

Abstract: A scrubber for removing pollutants from a fluid and having an inlet for receiving the fluid and an outlet for emitting the fluid, the scrubber comprising a first scrubber coupled with the fluid intermediate the inlet and the outlet for removing a first measure of pollutants from the fluid, a second scrubber coupled with the first scrubber intermediate the inlet and the outlet, the second scrubber for removing a second measure of pollutants from the fluid, and a third scrubber coupled with the second scrubber intermediate the inlet and the outlet, the third scrubber for removing a third measure of pollutants from the fluid.

Abstract: An embodiment of a sensing element (10) for a gas vapor detector (24) is formed from a gold-palladium alloy. The sensing element (10) is highly sensitive to phosphine or arsine gas. The by volume palladium concentration of the sensing element is typically less than 20%. The sensing element (10) is used as an active element in a gas vapor detector (24).

Abstract: A high conducting polymer-alloy blend is prepared by stress blending a polymer having Non-Newtonian rheological behavior with a low melting temperature alloy to form an interpenetrating polymer-alloy network. The blend is performed at a temperature intermediate the solidus and liquidus temperatures of the alloy where the alloy has a fractional solidus imparting to the alloy a viscosity corresponding to the viscosity of the polymer. In the resulting blend, the interpenetrating polymer network is the stabilizing component of the high conducting polymer-alloy interpenetrating network and the interpenetrating alloy network provides the high conductance path.

Abstract: A continuous fiber composite having carbon microfibers dispersed in the resin filling the interstices between the continuous fibers to enhance the transverse properties of the composite. The carbon microfibers are made by soaking carbon fibers in an intercalating acid solution comprising a mixture of fuming nitric and sulfuric acid to weaken the intercrystallite bonds. Gentle stirring of solution separates the carbon microfibers from the host fibers. The microfibers are then separated from the intercalating acid solution and washed to remove the residual acid.
