Patent number: 7800012Abstract: 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.Type: GrantFiled: October 19, 2004Date of Patent: September 21, 2010Assignees: La Calhene, Physique & IndustrieInventors: Michel Roche, Philippe Fontcuberta

Patent number: 5997399Abstract: 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.Type: GrantFiled: May 8, 1998Date of Patent: December 7, 1999Assignee: la Calhene, Inc.Inventor: Michael A.

Patent number: 5588473Abstract: 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).Type: GrantFiled: May 25, 1995Date of Patent: December 31, 1996Assignee: Sne La CalheneInventor: Charles Glachet

Patent number: 4915563Abstract: 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.Type: GrantFiled: January 9, 1989Date of Patent: April 10, 1990Assignee: Societe Nouvelle d'Exploitation La CalheneInventors: Eric Teillauchet, Angelo Bandiera, Laurent Girault

Patent number: 4898713Abstract: 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).Type: GrantFiled: March 10, 1988Date of Patent: February 6, 1990Assignee: Societe Nouvelle d'Exploitation La CalheneInventor: Claude Picard

Patent number: 4873885Abstract: 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).Type: GrantFiled: May 10, 1988Date of Patent: October 17, 1989Assignee: Societe Nouvelle D'Exploitation La CalheneInventors: Eric Teillauchet, Angelo Bandiera

Patent number: 4747601Abstract: 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.Type: GrantFiled: May 14, 1987Date of Patent: May 31, 1988Assignee: Societe Nouvelle d'exploitation de la CalheneInventor: Charles Glachet

Patent number: 4653793Abstract: 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.Type: GrantFiled: August 16, 1984Date of Patent: March 31, 1987Assignee: La Calhene Societe AnonymeInventors: Jean-Claude Guinot, Jean-Paul Lallemand, Denis Murguet, Said Zeghloul, Philippe Bidaud
