Cylindrical Patents (Class 901/17)
  • Patent number: 4564331
    Abstract: A robot of the type having a housing and a manipulator mounted to the housing and movable along a plurality of predetermined axes of movement. A drive mechanism is associated with the each axis of movement for moving, upon actuation, the manipulator along its respective axis of movement. The actuation of the drive mechanisms is controlled by a program drum which is rotatably mounted to the housing. A plurality of cam segments are adjustably secured to the drum at both axially and circumferentially spaced positions thus forming a plurality of axially spaced, segmented cam rings. A plurality of cam followers are secured to the housing so that one cam follower registers with each cam ring. Each cam follower is connected with an actuator so that, when the cam follower engages a cam segment on the drum, the actuator activates the drive mechanism corresponding to the particular cam ring. Conversely, the actuator deactivates its associated drive mechanism when the cam follower disengages from the cam segment.

  • 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: 4504186
    Abstract: A transporting device for lifting and relocating material from one position to another. In one embodiment, the transporting device comprises a stationary central support pedestal and a rotatable turret situated at the top of the pedestal. The turret has at least a pair of arms which extend radially outwardly from the pedestal. Each arm has an adjustable lifting and stacking mechanism for gripping and transporting of material as the turret is rotated. In another embodiment, the transporting device comprises a rotatable central support turret situated on a stationary pedestal. A pair of arms extend radially outwardly from the turret. Each arm may be raised and lowered independently of the other and includes a mechanism for gripping material as the turret is rotated. In either embodiment, the turret is driven by a motor situated in the stationary pedestal.
