THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

A1-CHEM FUELS, INC. HAS A PATENT PENDING FOR AN ELECTROTHER-MAL DEVICE TO PRODUCE MEDIUM TO HIGH BTU FUEL GAS FROM WASTEHYDROCARBON SOURCES. THIS UNIT OPERATES BY PRODUCING A HIGH-VOLTAGE ALTERNATING CURRENT ELECTRIC DISCHARGE ACROSS THE INTERFACE BETWEEN A WASTE HYDROCARBON AND WATER. THE EXTREMELY HIGH TEMPERATURE WITHIN THE ELECTRICAL DISCHARGE IS SUFFICIENT TO CAUSE LOCALIZED FAST PYROLYSIS OF ...

MODELING OF THE AMBIENT AND PROMPT IONOSPHERIC REGIONS IN A THIN LAYER APPROXIMATION ALLOWS AN EFFICIENT METHOD OF DETERMINING THE TIME EVOLUTION, PROPAGATION, AND SIGNAL STRENGTH OF THE 0-10 SECOND MHD EMP ASSOCIATED WITH HIGH ALTITUDE NUCLEAR DETONATIONS.

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...

LEARNING ABILITIES IN MATHEMATICS AND THE SCIENCES ARE NOT MAXIMIZED BECAUSE OF THE LACK OF VISUAL INSTRUCTIONAL MATERIALS. THE IMPROVEMENT OF THESE SKILLS IS IMPORTANT BECAUSE BETTER SCIENCE AND MATH ABILITIES ARE NEEDED IN THE UNITED STATES IN ORDER TO KEEP UP WITH OTHER INDUSTRIALIZED NATIONS. OUR PROPOSED SOLUTION IS TO USE A NEW TECHNOLOGY, THE TOPOLOGICAL PANORAMA CAMERA, TO CREATE COST-EFFE ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

A PHYSICAL PROPERTY OF EARTH FORMATIONS THAT STRONGLY INFLUENCES THE RATE OF ATTENUATION OF A SHOCK WAVE IS THE BULK VOLUME OF AIR OR GAS ENTRAINED IN THE POROSITY. AS A RESULT, THE ACCURATE DETERMINATION OF THIS GAS VOLUME IS IMPORTANT FOR PREDICTING THE EFFECT OF A SHOCK WAVE ON SUBSURFACE STRUCTURES. THE OIL AND GAS INDUSTRY HAS USED GEOPHYSICAL WELL LOGS FOR YEARS TO IDENTIFY AND EVALUATE THE ...
