Abstract: The invention relates to a bidirectional device for changing a handling glove from the inside towards the outside and from the outside towards the inside of a glove box under containment. The device is intended for replacing a used glove (60) with a new glove. The device comprises a cuff (6) sealingly connected to a cuff sleeve (20) and a glove (60) made of a flexible material sealingly connected to a glove sleeve (40). The glove sleeve comprises snap-fitting studs on the outside and the cuff sleeve comprises axial ramps (30). The snap-fitting studs of the glove sleeve slide in the axial ramps of the cuff sleeve until the glove sleeve is locked, forming, once assembled, a sealed assembly referred to as cuff port (10).

Abstract: A device for sealed attachment of an oval or circular interchangeable member in an oval or circular chamber ring including a mechanical system for secure immobilization of the interchangeable element through the retaining ring mounted on a wall of a containment cell. The attachment device includes an oval or circular retaining ring supporting the interchangeable member. The integral retaining ring includes at least three recesses and the chamber ring includes at least three bolts able to penetrate into the recesses in order to lock the retaining ring on the chamber ring. The retaining ring receives a set of keys supporting the interchangeable element.

Abstract: A radiation attenuation elastomeric material which includes an elastomer in which a powder of metal oxides is dispersed, wherein the powder of metal oxides includes from 70 to 90% by mass of bismuth trioxide, from 5 to 15% by mass of tungsten trioxide, and from 5 to 15% of lanthanum trioxide. Multilayer protective gloves incorporating this material are suitable for use in protecting a wearer from ionizing radiation when handling radioactive materials.

Abstract: A device for sealed attachment of an oval or circular interchangeable member (24) in an oval or circular chamber ring (8) including its own mechanical system for secure immobilisation of the interchangeable element through the retaining ring mounted on a wall (2) of a containment cell. This attachment device includes an oval or circular retaining ring (20) supporting the interchangeable member (24). The integral retaining ring (20) includes at least three recesses (26) and the chamber ring (8) includes at least three bolts (28) able to penetrate into the recesses (26) in order to lock the retaining ring (20) on the chamber ring (8). The retaining ring (20) receives a set of keys (22) supporting the interchangeable element.
