A special purpose robot to remove corrosion from the interior surfaces of the ductwork in AEDC's Engine Test Facility (ETF) will be designed and developed. The robot willimplemnt the Laser Induced Surface Improvement (LISI) process which alloys the interior surface of the ductwork with a chromimum compound. The system will include a remotely operated robot capable of traversing the ETF ductwork, ...

This proposal is directed at creating discontinuous unidirectional composite from continuous unidirectional prepreg. The process, Selectively-Discontinuous-Fiber (SDF), introduces micro-cuts in preimpregnated unidirectional materials at specified locations. This process will allow unidirectional composite prepreg to be used for the fabrication of complex-compound components that have be ...

Feasibility of rechargeable lithium-ion cells utilizing two ambient temperature molten salt electrolytes will be investigated. The anions of these electrolytes will be resistant to oxidation; the cation of one of the electrolytes will be resistant to both oxidation and reduction; therefore, in such electrolytes both cathode and anode will be electrochemically stable. The electrolytes will be pre ...

There is a substantial body of evidence demonstrating that biofilms growing inside the water lines of dental units pose a significant risk as a source of infection. The problem has been recognized by practitioners, regulators, manufacturers, and the ADA, with the ADA proposing a set of guidelines for water quality that include a limit of 200 colony forming units per milliliter for the year 2000. ...

Chemiluminescence is a powerful analytical technique that exhibits high sensitivity and selectivity. This technique when coupled with electrolysis is greatly advantageious over the conventional methods as the reagents are produced in situ at the electrode. The presence of trace amounts of solvents such as TCE, PCE, methylene chloride and carbon tetrachloride can be monitored using the method of ...

The prototype of an automated computer controlled precision hone will be built and evaluated in Phase I. The prototype hone will evaluate in situ bore measurement as a means to reduce the overall time required for maintenance honing of long tapered bores currently in use at a government facility. The measurement system would be used as a feedback signal to control the honing head's forward progr ...

Systems & Processes Engineering Corporation (SPEC) proposes to develop a Multi-Input Encoded/Decoder Application Specific Integrated Circuit (ASIC) chipset to be a programmable, universal interface between test equipment and digital recorders. The ASIC chepset will be fabricated using advanced GaAs MESFET technology. The Multi-Input Encoder/Decoder will be designed to interface both existing har ...

Environmental monitoring is difficult because of the large number of potential pollutants and broad range of their chemical classes. A multi-analyte environmental screening and monitoring instrument which is fast, portable, species specific, fieldable, cost-effective and flexible is clearly needed to plan and carry out the remediation of contaminated waste sites and to monitor and char ...
