  • Patent number: 4412372
    Abstract: The present invention is a method for the manufacture of bearing rings ruptured along an arrow-shaped partition line for antifriction bearings or similar devices. According to the invention a radial bore is introduced through the middle of the ring transversely of the bearing axis, and in the opposite end faces are introduced V-shaped notches which are displaced in relation to the radial bore in a circumferential direction. The bearing ring is supported on one end and ruptured first on that end by a force directed against the opposite end. The ring is turned over and again ruptured similarly until an arrow-shaped partition line extends from the radial bore to the notches.

  • Patent number: 4411478
    Abstract: A rolling bearing for lengthwise movement along a shaft comprised of an outer sleeve having a plurality of races therein for rolling bearings, a cage being provided to guide the rolling bearings. A sealing ring is provided at each end of the assembly, the sealing ring having lips extending radially inwardly to contact the shaft. The sealing lips are thin and elastically bendable, and are mounted to enable bowing thereof into free spaces on opposite sides thereof, depending upon direction of lengthwise movement of the shaft. As a consequence, for small movements of the shaft, the sealing lips cling to the shaft and become bulged, rather than sliding along the shaft.

  • Patent number: 4387939
    Abstract: A cage for a rolling bearing is formed of a plurality of cage parts. One of the cage parts is comb shaped, having axially extending cross-pieces adapted to be engaged by another cage piece, which may be a ring. Axially extending projections with enlarged ends are provided on the cage ring, at the inner circumference thereof, engaging correspondingly shaped recesses in the other cage part, thereby to enable snapping of the cage parts together. Recesses or projections are provided on the end of each cross-piece of the comb-shaped part, for engaging corresponding projections or recesses in the side ring of the cage, thereby to stabilize the cage in the circumferential and radial directions.

  • Patent number: 4383670
    Abstract: In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.

  • Patent number: 4374556
    Abstract: In a clutch release bearing assembly for a motor vehicle, the outer ring of a clutch thrust bearing has a flange engaging a radially extending flange of a housing part affixed to a sliding sleeve. This engagement permits play. An elastic ring is held fixed with respect to the outer bearing ring, and has projections extending axially from its internal circumference to engage circular surfaces of recesses of the housing. The circular surfaces of the recesses are joined by straight sections on the housing, whereby the tendency of the sliding sleeve to rotate with respect to the bearing ring effects the radial bending of the tongues, to damp such movement.

  • Patent number: 4368352
    Abstract: A digitizer having a pointer or cursor driven by an alternating carrier signal and a grid of sequentially enabled parallel spaced conductors inductively coupled to the cursor in which enabling of the conductors is initiated at an origin conductor and continues with a serial scan of the conductors until a phase change is detected when the cursor is between the origin conductor and an enabled conductor. The grid is sub-divided into overlapping sections which are scanned in sequence until the pointer is located. After the pointer is located, the conductor enabling scans begin at a conductor enabling device a predetermined distance from the enabling device actuated when pointer position was detected. Means are provided for re-initiating conductor enabling scans at the origin conductor in the absence of detection of the pointer.

  • Patent number: 4365819
    Abstract: A stroller for transporting a doll when pushed or pulled by a child has a pair of wheels secured to and rotatable with a horizontal axle, a right angle gear transmission from the axle to a vertical central shaft which is rotated when the stroller is propelled forward or backward. The top end of the vertical shaft is secured to and passes through the center of a frame formed as a seat for receiving and holding at least one doll. Rotation of the wheels when the stroller is pulled or pushed causes corresponding rotation of the vertical shaft and the canopy and the seat and doll therein.

  • Patent number: RE31143
    Abstract: A microscope-projector system is employed to image and view a transition of light and dark areas on an object. The position of the shadow corresponds to the vertical position of a portion of the object, and an adjustable device is employed for adjusting the position of the microscope-projector with respect to the object. A video camera may be connected to the microscope, to project the image on a monitor. Vertical adjustment of the microscope-projector assembly enables measurement of thickness, for example, with respect to a reference level. The scan lines of the video camera may also be employed to locate the position of the shadow to indicate the thickness of the object, and also to automatically readjust the position of the shadow to a reference level. Electronic circuitry may also play a part to determine from transition in scan lines the horizontal dimensions of an object.
