ATMOSPHERIC HCI MONITOR
Thomas E Kiser assigned to Professional Supply Inc An improved system for maintaining atmospheric conditions within prescribed parameters throughout the interior of a building. The building interior is essentially an enclosed system and sufficient outside air is admitted through air handling units to continuously maintain the interior of the building under a slight positive pressure throughout. Controllable vents are provided at strategic locations around the perimeter of the building, and sensing units are located throughout the building to continuously monitor atmospheric conditions such as temperature, humidity, and the level of particulates and pollutants. The sensing units or monitoring stations are periodically polled by a central computer, with signals from each station providing an indication of atmospheric conditions at that station. The signals representing existing atmospheric conditions are compared with stored data indicative of prescribed parameters for desired atmospheric conditions at the stations. Signals are generated in repsonse to noted deviations from the prescribed parameters, and the signals are utilized to regulate the controllable vents and air handling units so as to modify the incoming air or cause air to be discharged through appropriate vents in the area of the monitoring station until atmospheric conditions again fall within the prescribed parameters. Air is thus delivered from the air handling units to specified areas in a controlled manner without the use of ductwork.
Steven H Hoke assigned to The United States of America as represented by the Secretary of the Army A device for performing rapid determinations on a real-time basis of about three to five seconds of the concentration of HCI in the atmosphere includes an air inlet conduit for sampling the HCI laden air, a pump for introducing trapping solution into the air inlet conduit, a spiral impinger for mixing and combining the air and trapping solution, a separator for separating a portion of the trapping solution and entrained air from the remaining trapping solution, and electrode flow cell for receiving the remaining trapping solution and for determining the chloride ion concentration in the trapping solution. The electrode flow cell includes a measuring electrode having a silver wire having a silver chloride coating inserted in the flow path of the trapping solution. A selector valve is inserted between the separator and the flow cell for alternatively feeding either the separated trapping solution to the flow cell or a standardizing solution to the flow cell.
4960565 ACID MONITORING KIT William S Shurben, Kanata, Canada assigned to Ecostix Environmental Inc An acid monitoring kit is provided which is especially useful for monitoring acid rain. The kit includes a base plate having three discrete areas.
