Scoops
Ring-shaped stators having multiphase windings on low- loss
laminated iron core for synchronous operation of AC hysteresis
motors in vacuum. Power range is 50 to 1,000 VA for frequencies
600 to 2,000 Hz.
Tubes up to 12 mm (0.5 in) internal diameter for extraction of UF

Feed autoclaves that pass UF6 to centrifuge cascades, desublimers
that remove UF6 from the cascades, product and tails stations for
trapping UF6 into containers.
