Device for taking samples of molten metals flowing in pipes
First Claim
1. A device for obtaining samples of liquid metal and comprising a housing having an inlet and an outlet for the liquid metal, and containing crucibles having open tops and which can be filled while in the housing with the liquid metal and subsequently removed from the housing;
- wherein the improvement comprises positioning means in said housing for positioning said crucibles so they form a horizontal ring of crucibles, said inlet comprising a vertical feed pipe extending upwardly in said housing within said ring of crucibles and having an open top for the upward ejection of the liquid metal at a level above the open tops of the ring of crucibles, and baffle means for forming a baffle surface spaced above the feed pipe'"'"'s open top and the open tops of said ring of crucibles, said baffle surface being contoured to deflect liquid metal ejected upwardly from the feed pipe'"'"'s open top, downwardly into the open tops of said ring of crucibles.

Abstract
A device is described for taking samples from a liquid-metal-carrying pipe loop, in which the flowing liquid metal is a hot molten metal and may also be radioactive, e.g., metal in a main coolant loop of a sodium-cooled nuclear reactor. The device is suited for in-line as well as out-line operation and uses the conventional crucibles. The crucibles are arranged in a vertical housing in a circle around a vertical feed line for the liquid metal and extending upwardly into the housing. The liquid metal flowing into the device from the feed line'"'"'s upper end, is deflected downwardly into the crucibles by a downwardly facing concave baffle surface which is concentric with the feed line. The crucibles can be taken out of the device, hanging on an insert forming a closure for the housing'"'"'s top and that can be unscrewed and lifted, to obtain the crucibles. Improved arrangements of the thermocouples used for measuring the temperature of the liquid metal, and of the electric system required for heat the device are disclosed.
