  • Patent number: 4915563
    Abstract: Strips (20), housed in the slave arms (10) of a remote handling device and used for transmitting to the pair of gripping pliers borne by this arm orientation and tightening movements remote controlled by an operator, rotate pinions (26a) mounted at the extremity of the slave arm (10). These pinions (26a) are normally geared onto pinions (30a) mounted in a ball and socket joint (16) inserted between the pliers and the slave arm. When the ball and socket joint is dismounted, any attempt to remove the strips (20) is made impossible by the locking devices (60a) which come to rest onto the flanks of the pinions (26a) under the action of the spring (72). Any breakage of the strips due to their being pulled during dismantling of the ball and socket joint is thus avoided.

  • Patent number: 4898713
    Abstract: For sterilizing a tight enclosure (10) equipped with a ventilation and filtration circuit (14), said enclosure is isolated and the internal relative humidity level is lowered by means of an assembly (50) incorporating a drying cartridge (54). The sterilizing agent (46) is then introduced through a closed circuit (30) until a relative humidity level close to the dew point is obtained. The sterilizing agent is kept in the enclosure for a given contact time, before scavenging said agent by means of the ventilation and filtration circuit (14).

  • Patent number: 4873885
    Abstract: The open end of the shaft (10) of the slave arm of a telemanipulator carries two fixed hooks (50) able to encircle two spindles (52) projecting on either side of a toggle joint (16) supporting a gripper (18). Hooks (50) and spindles (52) form a pivot axis, which is displaced from the side of the pivot pin (34) of the gripper with respect to a plane parallel to the pivot axix and containing the longitudinal axis of shaft (10a). On the side of the plane opposite to the hooks (50) and the spindles (52), a latch (54) locks the case (16a) to the end of the shaft, thus, formed coupling device (15).
