RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF SCRAP TIRES HELPS TO RECOVER AND REUSE MOST OF THE VALUABLE CHEMICAL AVAILABLE IN TIRES. PYROLYSIS OF S ...

THIS PROJECT IS AIMED AT THE DEVELOPMENT OF A NEW GENERATION OF ROTARY BLOWOUT PREVENTERS CAPABLE OF SAFE, RELIABLE, AND COST EFFECTIVE HANDLING OF THE HIGH PRESSURES EXPECTED IN UNDERBALANCED HORIZONTAL AND DIRECTIONAL DRILLING APPLICATIONS. PRESSURES OF UP TO 5,000 PSI (OR EVEN HIGHER) CAN BE EXPECTED WHEN DRILLING WITH AIR, FOAM, OR NITRIFIED MUD IN THE LOW PERMEABILITY FORMATIONS IN THE U.S. ...

A NONDESTRUCTIVE ULTRASONIC METHOD CAPABLE OF QUANTITATIVELY EVALUATING THE BOND STRENGTH AND RESIDUAL INTERFACE STRESSES AT BRAZED JOINTS, SUCH AS CARBON/CARBON-COPPER USED IN FUSION REACTOR FIRST WALL STRUCTURES, IS PLANNED. THE MECHANICAL PROPERTIES AT THE INTERFACE CONTROL THE INTIMACY OF CONTACT. BY EXAMINING THE BOUNDARY CONDITIONS THE BONDLINE PROPERTIES MAY POTENTIALLY BE EVALUATED. TWO IN ...

A NEAR LINEAR ACCELERATOR (LINAC) STRUCTURE WILL BE IDENTIFIED AND INVESTIGATED IN PHASE I AS A POSSIBLE EXTENSION TO THE FAMILY OF STRUCTURES NOW USED FOR ACCELERATION OF CHARGED PARTICLE BEAMS. A CANDIDATE STRUCTURE HAS BEEN IDENTIFIED; OTHERS MAY BE IDENTIFIED IN THE COURSE OF THE INVESTIGATION. THE IDENTIFIED STRUCTURE UTILIZES A FOUR-FINGERED GEOMETRY TO PRODUCE RADIO FREQUENCY (RF) ELECTRI ...

THERE IS A RENEWED INTEREST IN FUEL CELLS AS PRIMARY POWER SOURCES FOR ELECTRIC VEHICLES. THE ACIDIC PROTON EXCHANGE MEMBRANE FUEL CELL OPERATES AT A MAXIMUM TEMPERATURE OF 95 DEGREES CENTIGRADE AND, AT PRESENT, RELIES ON THE USE OF PLATINUM-BASED ELECTROCATALYSTS. FOR ACID FUEL CELLS OPERATING AT TEMPERATURES BELOW 130 DEGREES CENTIGRADE, HYDROGEN IS THE MOST ACTIVE COMMON FUEL THAT CAN BE USED ...

GAS TRANSMISSION PIPELINES REQUIRE NATURAL GAS DELIVERED TO THEM TO MEET A HYDROCARBON (HC) DEWPOINT SPECIFICATION IN ORDER THAT THE HC LIQUIDS ARE NOT DROPPED OUT IN THE LINE DURING TRANSMISSION. SIMILAR SPECIFICATIONS ARE IMPOSED BY PLANT OPERATORS ON THE FUEL GAS THAT IS CONSUMED BY THEIR MACHINERY. A MARKET EXISTS FOR AN ECONOMICAL AMMONIA (NH3) ABSORPTION UNIT TO REPLACE COMPRESSION UNITS U ...

THE HARSH RADIATION ENVIRONMENT PRESENTED BY THE D-T BURNING PLASMA IN NEXT-STEP TOKAMAK FUSION DEVICES CAN CAUSE SEVERE DAMAGE TO CRITICAL OPTICAL COMPONENTS USED IN RESEARCH DIAGNOSTICS AND CONTROL INSTRUMENTATION. THE TECHNICAL OBJECTIVE OF PHASE I IS TO DETERMINE THE FEASIBILITY OF USING COMBINED THERMAL/OPTICAL ANNEALING TECHNIQUES TO MAINTAIN THE OPTICAL QUALITY OF THESE COMPONENTS. EXPER ...
