Abstract: A camera for observing the inside of a shielded cell comprises a support provided with a spring in the form of a gripper for mounting it on a remote- manipulation arm performing the task to be observed, by means of another arm, exerting solely a force for opening the branches of the spring, after which the camera is properly held, while being able to be removed without difficulty. A stop means is added in order to provide the correct angular position of the camera while preventing its support from turning about the arm, and thus making it possible to position it correctly by other remote-manipulation means.

Abstract: This dosing device (1) comprises a container (2) and a plug (4) comprising, in addition to a part (15) for connection to the container, two mobile outer parts (16 and 17). One of the mobile parts (16) is held in place during dosing, while the container (2) rotates continually to assist the flow of the content of same; the other outer part (17) can be rotated as necessary to adjust the opening of the plug. The movements can be carried out by a machine on which the dosing device is positioned upside down, with the plug facing downwards.
