The invention is directed to a filling arrangement for taking samples of radioactive process solutions from a liquid flow. The filling arrangement includes a filling head having a through-flow bore. The bore has a constriction in its cross section with first and second passages branching off from the through-flow bore forward of and rearward of the constriction, respectively. To reduce the risk of obstruction when samples of radioactive liquids containing solids are taken, the filling passages are formed so as to be mutually adjacent. The passages are open at the end remote from the through-flow bore and terminate in a conically tapered extension formed on the filling head. The open sample vessel is pushed over the conically tapered extension when taking a sample.

Filling arrangement for taking a sample of a radioactive process solution

An apparatus for taking samples of a toxic or radioactive substance by inducing such substance into sample vessels, comprising a rotatable cylinder containing a recess movable between two positions for receiving a sample vessel; a needle head filling assembly disposed at the first position; a stripper located between the cylinder and the filling assembly for causing the filling assembly to disengage from the sample vessel during downward axial movement of the cylinder after filling; a housing which is open at the top, and a cover closing the top of the housing, with the cylinder, filling assembly and stripper being disposed in the housing, and the cover being provided with an opening above the needle filling assembly and dimensioned to permit passage of the filling assembly through the opening; a supply conduit for supplying substance to the filling assembly; and a support disc located in the housing and provided with a receiving bore for supporting the filling assembly while permitting the assembly to be removed from the receiving bore and withdrawn from the housing via the opening in the cover, the support disc having a fluid flow bore for placing the supply conduit in communication with the assembly.

Sample taking device

An apparatus for taking a sample of a toxic and/or radioactive substance by ntroducing such substance into a sample vessel. The apparatus includes a rotatable cylinder containing a recess for receiving a sample vessel. A drive shaft is connected to the cylinder for imparting rotary and axial movements to the cylinder for moving the recess of the cylinder between first and second positions. A needle head filling system is arranged above the cylinder at the first position for filling a sample vessel with toxic and/or radioactive substances. The cylinder is lifted by the shaft for engagement with the needle head filling system when being filled and lowered by the shaft after being filled. An inlet and outlet conduit is provided having one end for receiving from and discharging into the recess of the cylinder a sample vessel, the one end being located above the cylinder at the second position. A stripper is located between the cylinder and the needle head filling system for disengaging the sample vessel from the needle head filling system when the cylinder is lowered by the shaft after being filled.

Apparatus for taking samples of toxic and/or radioactive liquid substances y introducing such substances into sample vessels, the apparatus including a holder for holding such a vessel, at least one needle head filling system composed of upwardly pointing hollow needles for introducing a sample of one such substance into such a vessel at a filling position, and inlet and outlet conduits for pneumatically conveying vessels to or from the holder at a transfer position, with the holder being composed of a turntable having a sleeve for accommodating such vessel and mounted to undergo rotary movement to convey a sample vessel held in the sleeve between the filling and transfer positions, and with the apparatus further including a stand supporting the filling system below the holder, and a lifting device connected for imparting a translational movement to the holder to bring a vessel in the holder to operative association with the filling system, the lifting device being arranged such that the translational movement which it produces is independent of the rotary movement of the turntable.
