Abstract: A sampling system in which carriers (1) containing sample bottles (4) are transported by pneumatic conveyor means (3) between an examination station, for example a laboratory, and a selected sampling station at a plant. On arrival at a sampling station (2) a bottle (4) is moved through a predetermined sequence of movements by a transfer arm (5) to cause the bottle to be removed from its carrier and placed over a sample dispenser (7) to introduce sample into the bottle. The bottle containing sample is then returned to the carrier for return to the examination station.

Abstract: Radioactive liquids are stored in coils placed in tanks containing circulating cooling medium. The liquid in the coil is circulated by a fluidic pump. In the event of a failure in the pumps circulating the cooling medium the decay heat will cause the cooling medium to boil. A reflux condensor fitted to the tank prevents loss of cooling medium during such periods of pump malfunction.
