Abstract

1,120,030. Observation windows. LOKOMOTIVBAU - ELEKTROTECHISCHE WERKE "HANS BEIMLER" VEB. 29 June, 1966, No. 29229/66. Heading F4B. [Also in Division F1] In an optical inspection device for a vacuum or pressure vessel 1, a disc 25 having slots 26 is attached to a rotor 18 mounted within the vacuum or pressure region. The stator 19 is mounted within a cap 27 outside the vacuum or pressure region. The process e.g. vaporization, melting, electron-beam material processing is viewed through optical discs 9, 10 when disc 25 is rotated at a speed above the flicker-free limit. In modifications one or more discs having one or more slots are used and ballbearings 21, 23 are replaced by plain bearings.
