THIS PROJECT COVERS THE DEVELOPMENT OF AN ADIABATIC DEMAGNETIZATION REFRIGERATOR FOR USE IN ZERO GRAVITY AND EMPLOYS AN INNOVATIVE PRECOOLER AND THERMAL SWITCH. IN ADDITION, THE PROJECT INVOLVES THE DESIGN OF A SUPERCONDUCTING MAGNET SYSTEM ENERGIZED BY A SUPERCONDUCTING FLUX PUMP. THE SYSTEM REQUIRES A 2K HEAT SINK FOR OPERATION.

THIS PROJECT CONCERNS THE DEVELOPMENT OF A CRYOCOOLER TO OPERATE AT 0.1 K IN ZERO GRAVITY. THE CRYOCOOLER WILL USE THE PRINCIPLE OF DILUTION OF HELIUM-3 SOLUTION BY PURE SUPERFLUID HELIUM-4 FOR THE COOLING EFFECT. A CONVENTIONAL DILUTION REFRIGERATOR REQUIRES GRAVITY FOR OPERATION, SO AN INNOVATIVE TECHNIQUE IS REQUIRED FOR THE ZERO GRAVITY SYSTEM. THE SYSTEM, WHICH REQUIRES A 2 K HEAT SINK, AND C ...

THIS PROPOSAL COVERS THE DEVELOPMENT OF A MULTISTAGE CRYOCOOLER USING THE MIKULIN PULSE TUBE CYCLE. THE EFFORT IS DIRECTED TOWARD THE DESIGN OF A HIGH RELIABILITY, LONG LIFETIME 20 K UNIT WITH A REFRIGERATION POWER OF 1 WATT.

THIS PROPOSAL COVERS THE DEVELOPMENT OF A FAST COOLDOWN LINDEHAMPSON CRYOCOOLER. BOTH SINGLE STAGE UNITS, REACHING 80 KELVIN, AND MULTI-STAGE UNITS, REACHING APPROXIMATELY 4 KELVIN ARE POSSIBLE. THE UNIT CAN BE USED WITH GAS BOTTLES FOR SHORT TERM USE. FOR LONG LIFETIME EITHER A MECHANICAL OR ABSORPTION COMPRESSOR CAN BE USED. THE UNIT CAN BE SCALED TO MATCH THE COOLING LOAD, AND MICROMINIATURE UN ...

INFANT VENTILATORS SHOULD BE TESTED UNDER PHYSIOLOGICAL LOADCONDITIONS BEFORE BEING USED FOR INFANT CARE. TESTING SHOULD ALSO BE PERFORMED PERIODICALLY DURING USE TO VERIFY THAT THEY ARE FUNCTIONING AS EXPECTED AND ACCORDING TO CRITERIA ESTABLISHED BY VARIOUS STANDARDS AGENCIES. THERE IS NO TESTER CURRENTLY AVAILABLE THAT ALLOWS THOROUGH TESTING OF MOST TYPES OF INFANT VENTILATORS IN ACCORDANCE WI ...

THE RESEARCH AND DEVELOPMENT EFFORT PROPOSED HEREIN WILL PROVIDE THE FOUNDATION AND METHODOLOGY FOR BUILDING A SIMPLIFIED STRUCTURAL AND DYNAMIC ANALYSIS CODE FOR MISSILE AND DEPLOYED OBJECT DESIGN ANALYSIS. THE CODE WILL GENERATE ALL CRITICAL DESIGN LOADING CONDITIONS USING AERODYNAMIC, PROPULSION, AND INERTIAL DATA AS INPUT. THE CODE WILL THEN APPLY THESE LOADS TO A SIMPLIFIED FINITE ELEMENT MOD ...

FEASIBILITY OF SHALLOW DEPTH COMPACT SLOW SAND FILTER TO TREAT DRINKING WATER FOR SMALL AND HOME WATER SYSTEMS IS INVESTIGATED. SHALLOW SAND LAYERS SUPPORTED AND COVERED WITH SELECTED GEOFILTER CLOTH EXAMINED TO DETERMINE FEASIBILITY OF SUCH AN APPROACH. THE PROJECT OBJECTIVES ARE: 1. IDENTIFY SUITABLE GEOFILTER CLOTH MATERIALS FOR USE IN WATER FILTRATION WHICH WILL SUPPORT FILTER SAND AND SAND SU ...
