  • Patent number: 4545569
    Abstract: Apparatus is described for remotely positioning, connecting, and generally andling components in a hot cell of a reprocessing plant for spent nuclear fuels. The apparatus includes a housing mounting a first stationary clamp for holding one end of a pipe and a second movable clamp for holding the end of a second pipe to be welded to the first. By adjusting the movable clamp, the pipe therein can be aligned with the pipe in the stationary clamp. The movable clamp can be moved longitudinally to press the pipe ends together, upwardly to compensate for pipe out of round, and can be tilted where pipes are to be joined at an angle. The adjustment permits accurate alignment of the parts. A tool support is rotatably mounted on said stationary clamp to permit welding or other processing through

  • Patent number: 4544318
    Abstract: A manufacturing system in which the automatic control of the system and the automatic control of a process management are organically coupled, thereby to sharply reduce the number of workers to be engaged in the manufacture. In order to establish both the versatility necessary for multiple type of treatment and the high efficiency necessary for large-quantity treatments, the arrangement of respective treatment sections is made the job-shop-type, and the construction of treating devices themselves included in the treatment sections is made the flow-shop-type, to achieve the consecutive automation. In order to also automate the management of the process, a stocker in which unfinished products are put is situated in a specified place of the system such as the central part thereof, while the process is put forward in such a manner that a conveyor machine controlled by a control unit having a computer reciprocates between the stocker and the groups of treatment sections.

  • Patent number: 4536124
    Abstract: A revolving-ladle turret having a turret member furnished with a pair of ladle-carrying arms, mounted on a platform which rotates about a vertical axis. The turret member is supported by a pair of articulated linkages similar to parallelograms of the double-handle type. The upper or bridge sides of the parallelograms are horizontal and rigidly supported by the platform and extend parallel to the ladle-carrying arms. These parallelograms have their respective handles shaped at right angles and are linked to the turret member in positions which are symmetrical to it about the axis of rotation of the platform. The articulated parallelograms fundamentally constitute synchronizing devices for the displacements of all of the points of the turret member and of the attached ladle-carrying arms.

  • Patent number: 4534695
    Abstract: A transport apparatus (10) for moving semiconductor wafers (12) between a cassette (15) and a process station (16), and from the process station to another cassette (17). A horizontally movable input shuttle (20) has three wafer holding elements (30, 32, 34) formed thereon. In a first position of the shuttle the second and third holding elements overly a pair of vertically movable lift plates (60), and in a second position of the shuttle the first and second holding elements overly the lift plates. A lifting mechanism (28) at the process station lifts wafers off the input shuttle when the shuttle is in its second position and deposits them on an output shuttle (22) which is essentially identical to the input shuttle. Wafers are lifted off the holding elements by the lift plates whenever the shuttle reaches either position, after which the lift plates replace the wafers on the shuttle and the shuttle is again moved.

  • Patent number: 4527934
    Abstract: Remotely-controlled manipulator carrier systems are used in large-area hot ells such as a facility for reprocessing irradiated nuclear fuel materials. The system is used to perform manual-like operations on the process equipment in the hot cell which is disposed in racks along two longitudinally extending walls of the hot cell enclosure, the racks being filled with process equipment and defining a passageway in the direction of the longitudinal axis of the enclosure. The system includes a vertical guide column which is connected to the bridge beam of an overhead bridge crane. A support is mounted on the guide column for movement up and down the column. An extendible arm is cantilever-mounted on the support and has a manipulator or other remotely-controlled apparatus at its outer end. The extendible arm is to be subjected to a minimal bending moment when work is done in the racks containing the process equipment.

  • Patent number: 4527945
    Abstract: A swivelling handle includes three reduction gear assemblies, each assuring the control of movement about the three axes of rotation. Each reduction gear assembly has a first reduction stage and a second reduction stage with coaxial drive. This arrangement makes possible great compactness. The third motor can be placed transversally, essentially in the axis of the second reduction unit. Thus a swivelling handle is obtained with three axes of rotation, with full electrical controls, in which the movements of rotation are created by three independent electric motors corresponding to each of the three axes of rotation. The unit is especially compact and adaptable to any type of industrial robot.
