FABRICATING STRUCTURAL ELEMENTS, SUCH AS I-BEAMS, FROM FIBERREINFORCED COMPOSITE MATERIALS. THESE ELEMENTS ARE EXPECTEDTO BE EXTREMELY STRONG, ONE-FOURTH THE DENSITY OF STEEL, ANDTO PERMIT CONSIDERABLE SAVINGS IN THE COST OF ERECTION, MAINTENANCE, AND REPLACEMENT OF BRIDGES, ETC. PHASE I WILL PRODUCE, TEST, AND ANALYZE I-BEAMS FABRICATED FROM SEVERAL MAGNAWEAVE CONSTRUCTIONS (WEAVE GEOMETRIES); TH ...

TWO YEARS AGO IT WAS EXPERIMENTALLY SHOWN THAT CHARGED WATERDROPLETS COULD KNOCK-DOWN SMOKE RAPIDLY. WE NOW PROPOSE TO TO DEVELOP A DEVICE WHICH USES A CHRGED FINELY POWERED SOLIDAEROSOL TO KNOCK-DOWN SMOKE. USING A SOLID INSTEAD OF A LIQUID AEROSOL HAS SIGNIFICANT ADVANTAGES. THE SOLID PART ICLES CAN BE PRE-FORMED IN A READY-TO-USE STATE. PARTICLE SIZE CAN BE RIGOROUSLY CONTROLLED AND HAVE OPTIMU ...

DUE TO THE IMPROVED MECHNICAL PROPERTIES AND DURABILITY OF POLYMER CONCRETE MATERIALS, THERE IS A LOT OF INTEREST IN INTHE HIGHWAY COMMUNITY FOR USE OF THESE MATERIALS FOR PAV PAVEMENT APPLICATIONS. BUT THERE IS NO INFORMATION AVAILABLEABOUT ITS APPLICATION FOR AIRPORT RUNWAY USE. PANDALAI COATINGS COMPANY PROPOSES TO TAKE UP A STUDY OF POLYMER CONCRETE MATERIALS TO EVALUATE ITS FEASIBILITY AS AN ...

IN 1982, A SPECIAL COMMITTEE OF THE NMAB ISSUED A REPORT ON THE NONDESTRUCTIVE METHODS THAT MIGHT BE USED TO MEASURE THELOGITUDINAL FORCE IN INSTALLED RAILS. IT SHOWED THAT THE ACOUSTO-ELASTIC EFFECT WHICH INFERS THE STRESS FROM MEASURE MENTS OF SMALL SHIFTS IN THE VELOCITY OF SOUND WAS PROMISINGBUT DIFFICULT TO IMPLEMENT BECAUSE VARIATIONS IN THE METALLURGICAL STRUCTURE OF THE METAL AND UNCERTAIN ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

PRIVATE INVESTMENTS IN TRANSPORTATION CAN BE PROFITABLE. THE HORIZONTAL DEVELOPMENT PROCESS (HDP), EMPLOYING A SPECIALIZED FORM OF PEOPLE-MOVER AS A HORIZONTAL ELEVATOR (H*E), MAXIMIZES THE DEVELOPMENT POTENTIAL, REDUCES THE RISK OF HIGH COSTS OR LOW INVESTMENT RETURN. AN HDP GUIDE WITH INDEPENDENT FINANCIAL APPRAISALS INCLUDING PROFORMA DATA AND PRELIMINARY UTAG (URBAN TRANSPORTATION ACTION GRANT ...

THE DEPARTMENT OF TRANSPORTATION (DOT) IS REQUIRED TO MAIN- TAIN THE NATION'S BRIDGES AND ENSURE THEIR SAFETY. HOWEVER,A LARGE NUMBER OF BRIDGES HAVE NOT BEEN RECENTLY INSPECTED TO DETERMINE IF THEY ARE CAPABLE OF SAFELY SUPPORTING THE TRAFFIC THAT IS CROSSING THEM. THE CURRENT METHOD OF SURVEYING BRIDGES, TO DETERMINE THEIR STRESS CONDITION, IS COSTLY AND TIME-CONSUMING. THIS PROGRAM WILL DEVELOP ...
