  • Patent number: 7800012
    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.

  • Patent number: 7282176
    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.

  • Patent number: 6357488
    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.

  • Patent number: 6307206
    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.

  • Patent number: 5997399
    Abstract: An apparatus for providing a clean working environment includes an isolation booth, a worker booth, and an access device arranged to enable a worker in the worker booth to handle material in an isolation chamber formed in the isolation booth. A pressure generator is positioned to communicate with the isolation chamber to generate an air pressure therein that is less than the air pressure of an air curtain passing through the worker booth so that air is drawn from the air curtain in the worker booth into the isolation chamber through any air leak opening that develops in and around the access device so as to block outflow of air in the isolation chamber to the worker booth through the air leak opening.

  • Patent number: 5588473
    Abstract: In order to transfer fluid products such as powders between a storage container (10) and a mobile container (18) an interface device comprising a tight chamber (24) is proposed. This tight chamber contains mechanisms making it possible either to seal an access opening (30) to the mobile container (18), or place a transfer tube (36) between the containers (27, 30). The transfer tube is formed by at least two sections (38, 40) having an internal cross-section which is substantially uniform and identical, so that a product can be transferred in any random orientation, without any risk of product being retained. The two sections (38, 40) can in particular be installed on the same tilting arm (42).

  • 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).

  • Patent number: 4747601
    Abstract: In order to permanently ensure the confinement of two closed volumes with respect to the outside atmosphere, while permitting the linking of said volumes, use is made of two gaskets, each having in section an approximately circular and generally hollow part, as well as a part forming a member. One of the gaskets is mounted by its member in a groove formed in a door received in a flange of the volume, whereas the member of the other gasket is fixed in a groove formed in a flange in which is received a door of the other volume. During engagement, the circular parts of the gaskets are in tight contact with one another and on V-shaped inclined surfaces formed within the flange and on the periphery of the door.

  • Patent number: 4653793
    Abstract: A gripper has n pseudospherical contact pads providing a point contact with an object to be gripped. The sum of the degrees of liberty existing between the object and each of the pads taken separately is less than, or preferably equal to, 6(n-1)-1. Moreover, the assembly constituted by the object, the pads, the fingers and the frame is isotatic, which means that the total number of degrees of liberty of this assembly is strictly equal to 6(n-1). Strain gauges placed on the fingers permit determining the tensor of the efforts exerted by the object on the gripper. An orientation of the object gripped can be accomplished by providing the pads with additional degrees of liberty controlled by independent actuators.
