Abstract: The need for specialized tooling which was previously required to accurately place the first layer of turns in a precision winding of a rotor having an even number of layers of turns is eliminated by providing self-fixturing wire-guiding features in corners of slots in the rotor which receive the winding, thereby facilitating the manufacture or repair of precision-wound rotors. In some exemplary embodiments, the self-fixturing wire-guiding features are provided by configuring the corners of the slots to include a chamfer or shoulder. In other exemplary embodiments, a specially shaped slot liner inserted into the slots includes a corner spacer which provides the self-fixturing wire-guiding feature.

Abstract: A sensor detects skewed adjacent movable component. The sensor may be used to detect harmful skews of aircraft control surfaces, such as slats or flaps on aircraft wings, which may be caused by an actuator disconnection from the surface it drives. Harmful skew, which is a relative asymmetrical motion of control surfaces beyond a predetermined limit, is detected by the sensor, but the relatively smaller harmless skew caused by normal flight is ignored. The sensor comprises first and second arms connected to a common base that may be attached to a first control surface. A constraining means such as a mechanical fuse holds the arms together while a separating means such as a spring exerts a separating force on the arms when the fuse breaks. A switching means is integral to the two arms. A striker pin on a second control surface strikes the first or second sensor arm when the relative motion between the control surfaces exceeds a certain predetermined limit.
