Abstract: In a smoke detection system, smoke density in a sampling chamber is measured by flashing a strobe light through the chamber and sensing light flux emitted from the chamber and comparing it with light flux from the strobe light itself. The measurements are performed by peak detectors which load sample-and-hold circuits to provide steady signals. The two signals are combined in mathematical manner to compensate for zero-offset and rate error between the two signals. The combined and corrected output is used to actuate a visual alarm signal, such as a segmented bargraph display to indicate air pollution. The bargraph has programming pins for tapping off each individual bargraph segment to achieve plural preset alarm thresholds.

Abstract: A gaseous fluid aspirator/pump apparatus including a rotary impeller (10) with radially extending blades, the impeller being mounted in a housing having a gaseous fluid inlet and outlet wherein gaseous fluid moving from the inlet (15) to the outlet (14) is turned from axial flow into the impeller to radial flow from the impeller, said impeller and an associated portion of the housing (16) being shaped to prevent flow separation and turbulence in the gaseous fluid stream while under the influence of the impeller. The impeller inlet (15) includes an inlet configuration of curvate conical from matching the configuration of the housing (16) in the area of the inlet opening. This configuration acting to prevent flow separation while turning the fluid flow through a large angle of approximately 90.degree. and acceleration and deceleration of the fluid flow is substantially prevented.
