  • Patent number: 5226781
    Abstract: For transferring products from a contaminated enclosure (12) into a second enclosure (16) without contaminating the latter, it is proposed to engage on the contaminated enclosure a transportation container (20), in which is placed an empty transfer chamber (22). After removing the coupled doors (C,F,H) of the contaminated enclosure, the container and the transfer chamber, the products to be transferred are introduced into the latter, without the space surrounding the chamber within the container communicating with the enclosure. This is followed by the reclosing of the coupled doors (C,F,H) and the disconnection of the container (20), in order to transport it and engage it on the second enclosure (16). The coupled doors (B'C', F) of said second enclosure and the container (20) are then opened in order to introduce into said second enclosure the transfer chamber (22) containing the products.

  • Patent number: 5090782
    Abstract: An interchangeable member (38), such as a glove, collar or bag, is fixed in a cell flange with the aid of a supporting ring (36) formed of two sections bearing an extremity flange (50) of the member (38) and also with the aid of a safety ring (72) secured to the flange (16) and to the supporting ring (36) by two bayonet links and rotational immobilized by two blocking members (82, 78) with respect to the flange and the supporting ring. A mounting tool (100) is equipped with an indexing part (136) which makes it possible to retract the blocking members when the safety ring is mounted.

  • Patent number: 5062761
    Abstract: A telescopic manipulation arm includes a module formed by two segments and a toggle joint. All movements of the toggle joint are transmitted across the module by identical mechanisms in such a way that the friction and inertia are the same for each movement. These mechanisms incorporate shafts positioned equidistantly of an axis in the lower segment and shafts positioned equidistantly of the axis in an upper segment. Shafts are provided for carrying identical pinions, which engage on identical toothed gears, and which are also engaged on substantially identical pinions rotatable with the shafts.

  • Patent number: 4897963
    Abstract: In order to place in sealed communication two reactor containments provided with openings capable of having a displacement between their axes, an assembly (12) is placed between the flanges (B.sub.1, B.sub.2) delimiting these openings, said assembly comprising two mobile linking parts (30a, 30b) according to a common axis, these parts bearing lip seals (36a, 36b) coming to take sealed support on the flanges under the action of a control (52) and springs (44) mechanism. Two double doors (14a, 14b) can be placed inside the openings and the linking parts in order to ensure separation of the containments. These double doors are formed of doors (16a, 18a, 16b, 18b) interconnected by means of magnets (62a, 64a, 62b, 64b) authorizing a certain relative sliding.
