Abstract: A rotary electric machine arranged as a brushless electric ring motor is described and includes a rotor that is disposed within a stator and arranged to rotate on a guide element. The rotor has a plurality of ferritic elements arranged on an outer surface, and the stator is an annular device having a plurality of electro-magnetic elements arranged on an inner portion between first and second flanges. The first and second flanges both include an annular ring that is fabricated from a non-magnetic material and has a plurality of ferromagnetic elements. The ferromagnetic elements are magnetically coupled to corresponding ones of the electro-magnetic elements to exert magnetic force on the ferritic elements of the rotor when the electro-magnetic elements are activated. The rotary electric machine may operate as a first thrust generating system that is upstream of a second thrust generating system for a turbojet engine.

Abstract: A tie-rod with a swivel tie-rod end includes a tie-rod central rod and a first tie-rod end including a swivel joint.

Abstract: Within examples, a system is described that includes a control lever for controlling operation of a device, a first actuator coupled to the control lever via a rod, and a resettable frangible link coupling a second actuator to the control lever via the rod. The resettable frangible link enables separation of coupling of the second actuator from the control lever based on an applied force to the rod by the first actuator.

Abstract: There is provided a portable wand system having a wand applicator, a wand controller subsystem, a selector assembly, an indicator element, and a power assembly. The wand controller subsystem includes a computer program, and a memory unit storing paths learned and recorded during a learn mode, by an operator manually moving the wand applicator. The paths include desired paths in stay-in zones to be surface treated, and include stay-out zone paths in, or near, stay-out zones to be avoided. The portable wand system is used in an operation mode to measure the operator manually moving the wand applicator in operation paths, based on the desired paths. For a selected stay-in zone, the portable wand system compares the operation path to the desired path, and indicates when the operation path deviates from the desired path, and when the wand applicator is in proximity to, and oriented towards, the stay-out zones.
