Abstract: An aircraft propeller has adjustable pitch blades which are reset from a low pitch in-flight idle position to a lower pitch ground idle position by a beta feedback and reset mechanism. The reset mechanism includes a set of cam elements supported for movement in response to rotation of the blades and positioned to engage a follower plate adjustably mounted on the beta feedback control rods.

Abstract: A planar-faced charge plate having individual charge electrodes uniformly spaced along one end face thereof is provided by wrapping a length of wire around a nonconductive charge plate support structure so that individual wire segments are positioned in parallel spaced relationship across the end face. Notches may also be formed along the opposite end faces of the charge plate support structure to facilitate the positioning of the wire segments. The wire is then adhered to the structure and the wire along one face of the structure is severed to form individual charge electrodes having leads traversing at least the top face of the structure. The end face having the charge electrodes is lapped to form a parallel face. This at times requires the removal of adhesive and/or insulation as well as a portion of the outwardly facing surfaces of the charge electrodes to form the planar-faced structure.
