LURGI AND IN SITU-GENERATED RAW COAL GAS CONTAIN TARS, PHENOLS AND LIGHT HYDROCARBONS. THESE BY-PRODUCTS ARE OFTEN UNMARKETABLE AND FORCE THE USE OF EXPENSIVE AND CUMBERSOME GAS CLEANUP SCHEMES TO REMOVE AND DISPOSE OF THEM. THIS PROJECT AIMS TO DEVELOP A CATALYTIC GAS CLEANUP STEP FOR CONVERSION OF BY-PRODUCTS IN THE RAW GAS TO ADDITIONAL H(2), CO, CO(2), AND CH(4). SUCH A CLEANUP STEP WOULD ELIM ...

THIS PROPOSAL IS FOR RESEARCH TO DETERMINE THE FEASIBILITY OF A PROCESS TO RECOVER ALL OF THE METAL AND CHEMICAL VALUESFROM SPENT PETROLEUM HYDROTREATING CATALYST IN SUCH A MANNERAS TO NEARLY ELIMINATE ANY HAZARDOUS WASTE CONSIDERATIONS. THE CRITICAL STEPS IN THE PROCESS ARE (1) ACID LEACH OF THE CATALYST AND (2) SEPARATION AND RECOVERY OF COBALT, NICKEL AND OTHER METALS FROM THE RESULTING LEACH S ...

THE ART SOFTWARE SYSTEM SPECIALLY TAILORED TO THE NEEDS OF DEMOGRAPHIC ANALYSIS. THE PROJECT WOULD PRODUCE A PACKAGE OF PROGRAMS SUITABLE FOR BOTH MAINFRAME AND MICRO-COMPUTER APPLICATIONS. PHASE ONE OF THIS PROJECT WILL IDENTIFY THE NEEDS OF POTENTIAL USERS OF THE PACKAGE AND SURVEY THE PRESENT STATE OF THE ART IN DEMOGRAPHIC SOFTWARE TO DETERMINE GAPS IN EXISTING MATERIALS. COMPONENTS OF A DEMOG ...

THIS PROJECT EXPLORES A MATHEMATICAL MODEL OF A MICROGRAVITYPROCESS INVOLVING MIXED CONVECTION HEAT TRANSFER, NAMELY, THE TIME DEPENDENT FLOW OF FLUID PAST A SPHERE SUBJECT TO A THERMAL GRADIENT. RESULTS OF THIS STUDY PROVIDE INSIGHT INTO THE BASIC FLUID MECHANICS INVOLVED IN SUCH PROCESSES AND ESTABLISH A FOUNDATION FOR EXTENDING THE ANALYSIS TO INCLUDE MASS TRANSFER BY DIFFUSION AND THE ASSOCIAT ...

A VARIETY OF ELECTRICAL/HYDRAULIC MOTORS, PUMPS, FANS, AND BLOWERS EMPLOYED WITHIN COMBAT VEHICLES IMPOSE UNACCEPTABLE NOISE LEVELS ON CREW MEMBERS. THIS INVESTIGATION ADDRESSES DEVELOPMENT AND EVALUATION OF A PROTOTYPE NOISE REDUCTION PROCESSOR SUITABLE FOR LATER IMPLEMENTATION WITHIN A SELF- CONTAINED HEADSET. COMMUNICATIONS BETWEEN CREW MEMBERS WOULDBE ACOUSTICALLY COUPLED WITH NOISE REDUCTION ...

A MULTIPLE ACCESS VOICE COMMUNICATIONS SYSTEM FOR USE IN STS SPACECRAFT IS PROPOSED. STS CREW MEMBERS WOULD WEAR A LIGHTWEIGHT BATTERY-POWERED, (RADIO) TRANSCEIVER HEADSET WHICH OPERATES THROUGH A FULL-DUPLEX, MULTIPLE (SIMULTANEOUS) ACCESS, RADIO REPEATER. THE PROPOSED SYSTEM UTILIZES AN ADAPTIVE NOISE CANCELLATION PROCESSOR (ANCP) FOR REDUCTION OF NOISE COMPONENTS CREATED BY ENVIRONMENTAL CONTRO ...
