摘要: A stereolithography system employing a more powerful laser and faster dynamic mirrors to speed up part building without sacrificing accuracy is described, especially large or complex parts. A controllable shutter is placed in the beam path of the laser to selectably block the passage of the beam and prevent unwanted solidification. A suitable servo controlled feedback loop is provided to accurately position the mirrors at the higher velocity.Also described is a means to reduce data flow by distributing tasks in a multiple processor environment, and to improve user interaction by the use of a spreadsheet model. These also improve the speed of part building, especially for large or complex parts.

摘要: A technique for substantially reducing nitrogen oxide (NO.sub.x) emissions in internal combustion engine exhaust gases. The NO.sub.x laden stream is contacted with a As catalytic material supported on a metal plated Ni foam substrate in the presence of a reducing agent. The NO.sub.x is reduced to nitrogen, water and/or carbon, and carbon dioxide.
