Abstract
The invention permits the automatic removal of a liquid sample without human intervention. The sample is removed during the pouring of liquid glass into its container. Use is made of a bucket fitted at the end of an oscillating arm. The mechanism is controlled by a fusible or meltable pellet, which melts when the glass level rises in the container. A prestressed spring and a counterweight enables the arm to pass from an initial position into a sampling position and then to a folded back position. The invention also provides an apparatus for raising the bucket and an apparatus for recovering the solidified sample in said bucket. The invention is used for taking a radioactive glass sample having to be permanently stored in a container.
