Abstract: An electron gun includes a sealed chamber under vacuum. A cathode having an emitting face is placed inside the chamber. An anode forms a sealed window, formed facing the emitting face in one of the walls of the chamber. The anode is capable of allowing electrons emitted by the emitting face to pass through. A biasing apparatus sets up a voltage between the anode and the cathode, capable of accelerating these electrons towards the anode, the electrons thus accelerated forming a beam that passes through the anode. The anode and the emitting face each have a curvature, the curvature of the anode making it capable of resisting a pressure difference between the inside and the outside of the chamber and being designed to cooperate with the curvature of the emitting face to focus the electron beam outside the chamber.

Abstract: A method to mount handling equipment on an interface of a confinement chamber that is to contain a sterile environment. In the method a unit including the handling equipment is prepared and sterilized, and the chamber and a hidden part of the interface are sterilized after coupling impervious tooling to a chamber flange and partially opening the chamber door. The unit is then coupled to the interface. Finally, the double door formed by the equipment door and the chamber door connected to one another is opened, using a handle provided for this purpose on the equipment door.

Abstract: Electron gun with focussing anode, forming a window of this gun, application to irradiation and sterilisation. This gun comprises a chamber (2) under a vacuum, containing a cathode (6) with an emitting face (8) emitting electrons, and an anode (4) formed in one of the walls of the chamber and transparent to electrons. The anode is curved to resist the pressure difference between the inside and the outside of the chamber. The emitting face is also curved and cooperates with the anode to focus electrons outside the chamber.

Abstract: In order to transfer aseptic products between two enclosures (34), use is made of a sterile container (10) having a filling interface (16) and an emptying interface (18). Each interface (16, 18) comprises a seal (24) behind which is placed a flexible hose (26) equipped with a closure system (30, 30′). The filling and emptying of the container (10) take place by connecting the corresponding interface (16, 18) and enclosure (34), sterilizing the volume trapped between the seal (24) and the door (42, 50) of the enclosure (34), opening said door and also the seal and putting into place the corresponding flexible hose (26). After filling the container (10), the closure system (30) of the filling interface (16) is closed again.

Abstract: Sterile products contained in a container (10) are transferred into a sterile isolator (12) by connecting the container onto a lock (28) fitted on the outside of the isolator (12) and equipped with a pulsed light sterilization device (28). The connection between the lock (28) and the isolator (12) is made by a sealed double door transfer device. The throwaway container is equipped with a plug type closer (16), cutout from the inside of the isolator (12) after sterilizing the volume (40) inside the lock (28) and opening the double door (24, 38).

Abstract: A tight transfer device (10) between two sterile volumes (12, 14), of the double door or port type (22, 26), is equipped with a decontamination system (44) using ultraviolet, pulsed ultraviolet or pulsed light radiation, of the facing points of the gaskets (30, 36) ensuring the necessary sealing action. This decontamination system (44) is integrated into one (20) of the flanges of the transfer device. It comprises a collar (46) made from a material able to diffuse radiation, as well as optical fibers (48), whereof one end is mounted on said collar. The other end of the optical fibers (48) is connected to a radiation source. When the source is used, the radiation, routed by fibers (48) over the entire periphery of the collar (46), diffuse into the same towards the points of the gaskets (30, 36) to be decontaminated.

Abstract: Cover to place on a door (5) with unlocking by means of rotation as to slightly open it and making it possible to appropriately sterilize the entire inside of the receptacle it closes, whilst enabling bactericide vapors to easily reach the surfaces adjacent to the door. In order to do this, the cover includes a fixed dome portion (20) flanged on the receptacle around the door, and a handling device (40 to 42) created through the dome and able to grip the door so as to slightly lift it up without breaking its imperviousness.

Abstract: To ensure the disconnectable connection of two components with a non-circular outline, in particular an oval outline, a rotatable ring of oval shape is fitted on a first component, cooperating with a second component by a bayonet system. Rotation of the ring is made possible by positioning at least four arc of a circle shaped segments along the desired outline with a space between the ends of adjacent segments. The link between these ends is made by articulated components.

Abstract: The invention relates to a safety device for an interlocking mechanism between two sealed enclosures such as found in biological or nuclear environments and which prevents accidental opening of one or the other of two doors closing off the enclosures, which prevents leakage from the enclosures and which may be readily retrofitted to an existing locking system. The locking system comprises a locking ring (36) rotatable between an inoperative position and a locking position for locking the two enclosures and an operating lever for locking the two doors. The safety device includes two locking mechanisms electrically controlled by four prepositioned detection means on the form of microswitches for locking and unlocking the two locking mechanisms.

Abstract: A telescopic telemanipulator of the master-slave type, wherein the slave arm is equilibrated by means of at least one counterweight mounted on a link articulated to the traversing block on the master arm side, the counterweight moving along the link when an offsetting is introduced between the length of the slave arm and that of the master arm; at least a second counterweight is mounted adjacent the first counterweight on another link, such counterweight moving along the link when a variation in the length of the slave arm is controlled from the master arm.The telemanipulator has application for the remote-controlled handling, among other things, of radioactive products.

Abstract: The invention relates to a circuit for ventilating and filtering the medium contained in a confinement enclosure (10) and also a method for sterilizing such an enclosure and its supply and discharge filters.An emergency or standby circuit is associated with the circuit ensuring ventilation and filtration under normal operating conditions and which comprises a supply pipe (20) and a discharge pipe (12), equipped with a suction fan (14). The said emergency circuit comprises the same pipes used in the opposite direction under the action of a suction fan (28) located in supply pipe (20), whereby said fan (28) can be automatically controlled by a pressostat (30).
