    Abstract: A recirculating-ball drive has a ball nut centered on an axis and formed with an internal helical groove and receiving a spindle centered on the axis also and rotatable in the nut about the axis. This spindle is formed with an external helical groove of substantially the same pitch as the groove of the nut and having two turns interrupted by a substantially planar flat spaced radially outwardly of the axis. Faces of wedges bolted to the flat define thereon a pair of parallel guide surfaces which in turn define with the flat a passage extending between the interrupted turns of the spindle groove at an angle opposite the pitch angle of the spindle groove. An annular row of like balls fills the passage and the turn of the spindle groove interrupted at both ends by the flat.

    Abstract: An electromechanically reciprocable load has a driving spring tending to displace it from a retracted position into a working position upon the release of a locking brake. The spring force is opposed by the countervailing force of an electric motor which, during the working stroke, is progressively reduced in keeping with the diminishing force of the relaxing spring. When the load includes a caliper of a power brake arresting a rotary element in its working positon, the motor is controlled by a bridge circuit with two potentiometers whose wipers are entrained, with a relative lag, by the load so as to establish a variable null position advancing with progressive wear of the brake linings in order to keep constant the travel of the load during a return stroke brought about by the energization of the electric motor with an overriding signal. An accelerometer monitors the speed of the rotary element to soften the impact of sudden deceleration in the final phase of the brake-actuating stroke by temporarily increasing the countervailing motor force if the rate of deceleration exceeds a predetermined threshold.

    Abstract: A spindle or leadscrew and an associated nut, forming part of a driving assembly of the circulating-ball type, have helical threads of symmetrical profiles in the shape of pointed arches whose flanks engage the recirculating balls along respective helical contact lines. With the spindle virtually non-deformable in the axial direction, the pitch of its thread exceeds that of the nut thread (in the absence of stress upon the latter) by a small differential--specifically 0.02%--lying well within the limits of elastic axial deformability of the nut. Upon rotation of the spindle relative to the nut for the transmission of an axial force, this differential results in an approximately uniform stress distribution among the sets of balls lying in confronting turns of the spindle and nut threads.

    Abstract: A leadscrew and a coacting nut are provided with shallow helical grooves forming a track for a set of balls whose radius exceeds the combined depth of the grooves. The groove bottoms are of arcuate cross-section, with a radius of curvature slightly exceeding the ball radius, and are machined in a hardened zone of the leadscrew and the nut, respectively.

    Abstract: A motor has a shaft carrying a dielectric disk on whose edge is fitted an undulating iron ring formed with a plurality of angularly equispaced points that pass beneath a magnetic detector head that generates a sinusoidal voltage signal having a frequency proportional to the rotation velocity of the shaft. This sinusoidal signal is clipped at a minimum signal level and then fed to an amplifier once it has passed through a resonant circuit tuned to a frequency corresponding to the desired motor rotation speed. The output side of this resonant circuit is connected via a capacitor and variable resistance to the input of a Schmitt trigger which operates a relay controlling the motor so as to maintain the motor speed within a desired range.

    Abstract: Two relatively movable bodies, such as a screw and a nut, engage each other through the intermediary of an endless row of balls guided in a closed guide path including a groove formed in a surface of one body confronting the other body. The guide path further includes at least one substantially prismatic bridge piece inserted in the grooved body and formed with an open-ended recess generally perpendicular to the groove, this recess communicating with one end of that groove and either with the opposite end of the same groove or with a corresponding end of a companion groove. The parallel end faces of the bridge piece are flush with opposite surfaces of the grooved body and, in the specific instances here described, are inclined with reference to the direction of the recess.
