摘要:
A process is disclosed whereby NO.sub.x and SO.sub.x components contained in stack gases are simultaneously reduced to N.sub.2 and H.sub.2 S, respectively, by passing said stack gases (which also contain steam and usually some oxygen) over bituminous coke at between about 900.degree. and 1600.degree. F.
摘要:
A moving target system for defensive training includes an elongated ground-based track defining a track axis, a trolley operable to move along the track, the trolley having a target support facility, a driver operable to move the trolley along the track, and the target facing in a direction angularly offset from perpendicular to the track axis. The target support facility may be operable to fall from a vertical position when the trolley reaches an end of the track. There may be an actuator operably connected to the driver to initiate movement of the trolley when actuated.
