A saw apparatus for removing the wedges maintaining the winding coils in the slots of a generator, such as a hydroelectric generator, clamps to the grooves of the slot next to the slot containing the wedges to be removed. The apparatus includes a circular power saw for sawing the wedges in half, reducing the time required for the rewinding operation.

A coil removal apparatus for a dynamoelectric generator. This apparatus directs a radial pulling force on the legs of a coil to be removed from stator core slots during rewinding operations. The apparatus includes a frame including a frame member of predetermined length. A pair of gripper members are provided with grippers jaws to grasp each leg of a coil to be removed. The gripper members are connected to the frame member. The frame member is connected to a pulling mechanism that applies a horizontal force to the frame member to pull the coil out of the slots without binding in the slots.

A conductor bundle edge-bending tool is disclosed. The apparatus is designed to bend a conductor bundle of a coil of a dynamoelectric generator along its edge. The apparatus is easy to use and prevents lateral deformation of the conductor bundle and provides a large mechanical advantage.

Conductor bundle edge-bending tool for a dynamoelectric generator

A winding temporary positioning apparatus for a dynamoelectric generator. The apparatus is particularly useful during rewinding of a generator of the type that has wedges maintained in grooves in the stator core slots holding the windings in position. The apparatus of the present invention includes adjustable arms shaped at the bottom end of the arms to engage the grooves thereby temporarily holding the windings in place until permanent wedges are installed.

The spent fuel consolidation system provides method and apparatus for remotely vertically and horizontally compacting an array of spent fuel rods while the fuel rods remain submerged in a coolant. The invention comprises a row ordering section for rearranging the configuration of the fuel rods, horizontal consolidation section for horizontally compacting several rows of fuel rods, and a vertical consolidation section for vertically compacting several rows of horizontally compacted fuel rods. The system is capable of compacting the fuel rods from a given fuel assembly to about one half of the volume originally occupied by such fuel rods in the fuel assembly thereby providing greater storage capacity for a given volume of spent fuel storage.
