AIR TOXIC METALS AND THEIR COMPOUNDS ARE PRODUCED FROM THE COMBUSTION OF FOSSIL-FUELS. THE COMBUSTION OF COAL AND FUEL OIL REPRESENTS AN EXTREMELY LARGE CATEGORY OF SOURCE EMISSIONS. RESEARCH IS PROPOSED THAT WILL PROVIDE A MEANS FOR REMOVING THE VOLATILE METAL CONTENT OF FLUE GAS GENERATED FROM POWER AND STEAM GENERATING PLANTS USING ZEOLITIC OR CARBONACEOUS ADSORBENTS. A LABORATORY-SCALE FIXTURE ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

ION EXCHANGE IS AN ATTRACTIVE TECHNOLOGY FOR REMOVAL OF HEAVY METALS FROM WATER AND WASTEWATERS, BUT IT IS COMMONLY FOUND TO BE UNECONOMICAL DUE TO THE HIGH COST OF CHEMICALS AND DISPOSAL OF THE BRINES OR SECONDARY WASTES GENERATED. SEVERAL IMPROVEMENTS TO THIS TECHNOLOGY ARE PROPOSED TO ALLOW ION EXCHANGE TO BE MORE WIDELY APPLIED TO THE REMOVAL OF TOXIC HEAVY METALS AT SUPERFUND SITES AND IN OTH ...

THE FLUOROCARBON INDUSTRY IN THE UNITED STATES CURRENTLY GENERATES OVER 1,200,000 POUNDS OF SPENT ANTIMONY FLUOROCARBON CATALYST ANNUALLY IN PRODUCING 1,190 MILLION POUNDS OF FLUOROCARBONS (CFCS, HCFCS, HFCS). THIS SPENT CATALYST IS A MIXTURE OF HALOGENATED ORGANIC COMPOUNDS (HOCS), ANTIMONY, AND ARSENIC HALIDES. IT IS EXTREMELY HAZARDOUS, TOXIC, AND CORROSIVE. IT CONTAINS AT LEAST EIGHT LISTED "C ...

Replacements for the halocarbons banned by the Montreal Protocol will be producedby technologies which generate spent catalysts as a waste byproduct. These spentcatalysts contain tin, a valuable metal resource, in a matrix that willundoubtedly be classified as hazardous with regard to its disposal.Chemical & Metal Industries, Inc., proposed in this Phase I effort to investigatetwo alternative tec ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...

THIS PROJECT AIMS AT DEVELOPING A HIGHLY ACCURATE AND ECONOMICAL AIRCRAFT ALTIMETER. THE MOTION OF AN EVACUATED BELLOWS WILL BE MONITORED BY AN OPTICAL POSITION SENSOR WHICH WILL GIVE AN ELECTRICAL ANALOG SIGNAL LINEARLY RELATED TO THE ATMOSPHERIC PRESSURE. WHILE THE SENSOR IS VERY SMALL, RUGGED AND INEXPENSIVE, IT HAS A LARGE DYNAMIC RANGE (100,000), HIGH LINEARITY (0.01%) AND HIGH SENSITIVITY (M ...
