Abstract: Apparatus for centering the inertial member of a gyroscope or an accelerometer wherein the member is maintained in suspension by means of electric fields between electrodes. Three pairs of electrodes are provided, each pair positioned to apply forces on the inertial member along one of three orthogonal axes and each being energized by an electronic channel. A dither signal is introduced into one of the channels. If the inertial member is not perfectly centered between the support electrodes, cross-coupling of electric forces between the channels will occur. Therefore, miscentering of the inertial member will result in appearance of signals in the other two channels corresponding to the dither signal introduced into the first channel. The polarity and the amplitude of such signals are indicative of the direction and the magnitude of miscentering and provide the information which is fed back into the suspension servo to close an automatic adaptive precision centering loop.

A pair of concentric counterweight discs each having lightening holes to render the discs weighted to one side and these unbalanced discs are positioned in the spinning hub of a rotating engine. Control signals are transmitted to activate a pair of servo motors each controlling the angular position of one counterweight disc. The angular position of the discs with respect to each other can be controlled as well as the angular position of the pair of discs taken together with respect to the rotating engine.

Abstract: A set of removable combination cams has an assembly of identical rotary components mounted on a common rotary shaft and carrying removable cams for operation of switches. The rotary components are coupled together in such a manner that they can move relatively perpendicular to the axis of rotation, so that at least a portion of the periphery of one of the components is uncovered to allow fitting of the cam elements. Thus, the cam elements can be fitted without dismantling the assembly, and without changing the relative angular positioning of the rotary components, and without utilising resilient deformation of the materials employed, whilst retaining small axial dimensions for the assembly.
