Abstract

921,884. Viewing equipment for radio-active environment. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Dec. 22, 1961 [March 2, 1961], No. 45978/61. Class 39 (4). An observation port for a hot cell having a wall 2 comprises a cylindrical lead casing 3 mounted for rotation on a shaft 6 in a lead block 1 removably mounted in the wall. The direct path between a viewing window 4 and hot cell window 5 secured to the casing is obstructed by a prismatic-shaped lead part 11 rotatable with the casing, the light rays being transmitted by four pairs of mirrors 7a . . . 7d and 8a . . . 8d removably secured to the casing 3 and part 11 by frames and screws (Fig. 2, not shown).
