Halbach Array DC Motor/Generator
U.S. Patent 5,705,902
January 6, 1998
This direct-current (DC) motor/generator based on a Halbach array of permanent magnets does not use ferrous materials; thus, the only losses are winding losses and losses due to bearings and windage. The rotor is on the outside of the machine, and the stator forms the inside of the machine. The rotor contains an array of permanent magnets that provide a uniform field. The windings of the motor are placed in or on the stator. The stator windings are switched or commuted to provide a DC motor/generator.

Plasma-Assisted Catalytic Reduction System
U.S. Patent 5,711,147
January 27, 1998
This inexpensive and reliable system for reducing NOx emissions, particularly in gasoline-powered vehicles and engines with oxygen-rich exhaust, combines nonthermal plasma gas treatment with selective catalytic reduction. A first reactor converts NO to NO2, and a second reactor reduces the output of the first to produce an exhaust with reduced NOx emissions.





Awards

David Leary, head of the Laboratory's Business Services Department, received a Hammer Award for his efforts as part of a Department of Energy team to streamline property management regulations and performance evaluation, so that the latter is not regulation-based but outcome-based as it is in private industry. The award was given to a joint DOE/contractor value-based self-assessment team of which Leary was a member. The Hammer awards were created by Vice President Al Gore to recognize special achievements in the efforts to reinvent government by cutting red tape and making government more efficient. They are given to individuals and teams that have made significant contributions in support of the President's National Performance Review principles.
Stan Trost has been named an Executive Fellow of the Institute of Electrical and Electronics Engineers and will serve one year with the Federal Communications Commission (FCC) in Washington, D.C. Trost will work in the FCC's Office of Plans and Policy on a broad range of deregulation issues resulting from the Telecommunications Act of 1996. Among the deregulation issues the FCC faces are the Year 2000 problem and critical communication infrastructure, reliability, openness, and service issues related to the Internet. Currently, Trost is a program manager in the Nonproliferation, Arms Control, and International Security Directorate. Previously, he was deputy associate director for electronics engineering and has held a variety of development and leadership positions focusing on information technology.
