Abstract: A torque coupler includes a first torque plate having a first slot extending in a radial direction, and a second torque plate having a second slot extending in the radial direction. The second slot has a side formed of a flexible beam. A cam plate is pivotable about an axis, and has a cam slot having a first portion at a first radial distance from the axis and a second portion at a second radial distance, where the second distance is greater than the first distance. A torque transfer member is slidably received within the first slot, the second slot, and the cam slot. The transfer member transferring torque between the first and second torque plates. A drive device rotates the cam plate about the axis, which causes the first cam slot to radially slide the transfer member along the flexible beam.

Abstract: A workpiece positioner assembly comprises a headstock apparatus that is configured to rotate a workpiece A headstock interface assembly is configured to secure the workpiece to the headstock apparatus and comprises a bearing configured to enable pitch, yaw and roll movement of the headstock interface assembly relative to the headstock apparatus. The workpiece positioner assembly further comprises a tailstock apparatus configured to support the workpiece in cooperation with the headstock apparatus. The tailstock apparatus comprises a tailstock interface assembly that is configured to secure the workpiece to the tailstock apparatus. The tailstock interface assembly further comprises a tailstock bearing configured to enable axial movement of the workpiece relative to the tailstock apparatus.

Abstract: A device for inspecting a component, such as a dovetail slot of a gas turbine engine or the like, includes an eddy current array circuit having an active face for positioning on the surface of the component during the inspection operation and a backing disposed on a face of the eddy current array circuit opposite to the active face. The eddy current array circuit and the backing are disposed over the operating face and expandable sides of an expandable bar. The expandable bar has a slot formed therein with interior side edges which narrow toward the operating face of the bar at a predetermined slope. An expanding wedge with angled sides is positioned to cause the angled sides to respectively matingly engage the interior sides of the slot to cause the exterior sides of the expandable bar to expand outwardly a greater distance as the wedge is pushed deeper into the slot to cause the eddy current array circuit into conformance with the shape of the surface being inspected.

Abstract: An eddy current device for inspecting a component includes an eddy current array circuit having respective pluralities of drive and sense elements and having an active face for positioning on a surface of the component during the inspection operation. A backing is disposed on a face of the eddy current array circuit opposite to the active face for concentrating an electromagnetic flux from the eddy current array circuit into the component when each of the plurality of drive elements is being energized. A mechanical arrangement is provided for supporting and deploying the backing and the array circuit to substantially conform with the surface portion under inspection and to cause each of the pluralities of drive and sense elements to be maintained at their respective substantially constant distances from the inspection surface during scanning, preferably at a controlled rate of scan.
