A hinge for an aircraft power distribution system unit is provided. The unit has a housing comprising a first housing part and a second housing part. The hinge comprises a first hinge member for connection to the first housing part of the unit; and a second hinge member for connection to the second housing part of the unit, wherein the first and the second hinge members comprise an electrically conductive material and wherein the first and the second hinge members are connectable to one another to establish an electrical connection between the first and the second hinge members and to allow relative rotation between the first and the second hinge members.

An induction rotor includes a rotor core having an axial end surface, an end ring proximate the axial end surface that provides electrical communication between respective ends of conductor bars extending through the rotor core, and an end ring support structure that includes a ring member at least partially embedded in the end ring. An end ring support structure may have at least one axially extending member coupled with the ring member, such axially extending member projecting axially inwardly of the axial end surface and engaging the rotor core. An end ring support structure may include a ring member having an axially extending portion embedded in the end ring between radially inner and outer surfaces of the end ring whereby the end ring includes an outer portion, radially outwardly of the axially extending portion, and an inner portion disposed radially inwardly of the axially extending portion of the ring member.

A mode shifting apparatus for a decoking tool, a decoking tool and method of operating same. The apparatus includes features to make it rotatably and translationally responsive to changes in pressure of a decoking fluid such that the apparatus is cooperative with the tool and the decoking fluid in a first operating condition to establish a drilling mode with one or more of the tool's drilling nozzles, and in a second operating condition to establish a cutting mode with one or more of the tool's cutting nozzles. In one form, the apparatus includes one or more sets of tandem seals disposed along a component interface within the apparatus or between the apparatus and the tool to help redundantly isolate seizure-sensitive components within the apparatus from the pressurized decoking fluid. In another form, the apparatus includes a gas spring to counteract the forces imposed by the pressurized decoking fluid. In another form, the apparatus includes a manual override connection.
