Abstract: An apparatus in which the lateral movement of a belt arranged to move along a pre-determined path is controlled. The apparatus includes a belt sensor mounted translatably on a belt support. As the belt moves laterally, the sensor translates therewith causing the belt support to pivot so as to return the belt to the pre-determined path.

Abstract: An apparatus in which lateral movement of a moving belt is controlled so that the belt moves in a pre-determined path. The apparatus includes at least one moving member having a plurality of spaced, flexible discs extending outwardly from the exterior surface thereof. The portion or segment of the disc contacting the region of the belt passing thereover provides support therefor. Preventing the belt from deviating laterally from the pre-determined path deflects the portion or segments of the discs providing support for the belt. The deflected portion of the disc returns to the undeflected condition when not supporting the belt. In this manner, the maximum force applied to the belt never exceeds the minimum force required to buckle the belt.

Abstract: A roller mounted for universal angular movement relatively to its nominal longitudinal axis of rotation so as to be angularly displaced by the weight and movement of the conveyor belt when the conveyor belt shifts away from running true. This angular displacement brings the rotating roller into engagement with reaction faces provided on the frame of the conveyor and causes the roller to be reactively displaced in a direction to restore the belt to running true.

Abstract: To decrease forces acting on the edge of magnetic tape, typically wide tape (25.4 mm-1"), and thus prevent damage to the edge, the surface of deflection guide rollers is formed to be resilient and permitting axial deflection, but returning to the nominal radial position when not deflected or deformed by axial forces applied thereto by the magnetic tape. The surface may be formed by bristles extending radially, ring-shaped foam strips, ball bearing-supported rings in which the bearings have slight axial play, or resiliently deflectable sheet metal rings, the axial restoring forces of ball bearing-supported rings being provided by centrifugal forces tending to align the bearing in a plane exactly transversely to the axis of rotation. The forces then acting between the magnetic tape and diametrically projecting guide flanges are reduced since slight axial deflection, in the order of about 0.001 mm, in permitted.

Abstract: A rotating body, such as a pulley or a guide wheel, is oscillatable along its rotational axis. The rotating body is carried by a longitudinal support having a cam surface extending generally perpendicular to the rotational axis. The support is mounted for rotation with a supporting shaft and is biased along the rotational axis so that the cam surface engages a stationary cam follower. Rotation of the shaft, support, and body relative to the cam follower results in the oscillation of the rotatable body.

Abstract: A magnetic card transport system for an electronic typewriter comprises a reversible drive roller and a coacting pinch roller which form a nip through which a magnetic card is passed. The drive roll and pinch coact to move the card in opposite directions. A guide surface is provided which is engaged by one longitudinal edge of the card, and guide springs are provided which engage the other longitudinal edge of the card to urge the card into engagement with the guide surface for registration purposes. The pinch roll is mounted in such a manner that it may freely oscillate. The oscillation is such that the pinch roll axis pivots in each direction from a line substantially perpendicular to the guide surface between 1/2.degree. and 3.degree. about a vertical axis normal to its axis of rotation to allow for self-alignment to maintain the card in alignment with the guide surface.

Abstract: An adjustable-bow bar or roll axle, useful for spreading slit sheets of paper and for other purposes, includes a hollow cylindrical shell. Two tension bolts extend along axes parallel to the centerline of the shell, and interconnect the ends of the bar or axle. One of the bolts lies in a plane of desired curvature of the bar and applies a bending moment to curve the bar in this plane; this bolt may be located inside or outside the shell, depending on the required bending moment. The second bolt may be inside the shell; its angular position is adjustable with respect to that of the first. This bolt is set in the plane of a resultant force applied to the bar by the tension in the sheet, and applies a bending moment to offset this force and prevent curvature of the bar in this plane. A third bolt may be located in a vertical plane to apply a bending moment to prevent curvature of the bar by its weight; or the second bolt may serve this purpose also.
