  • Patent number: 4511971
    Abstract: An antilocking brake system responds to a deceleration above about 12 m/s.sup.2 and resulting from overbraking to cut off the master cylinder from the wheel brake cylinder and effect braking-force reduction. When the deceleration falls below about 10 m/s.sup.2, a threshold discriminator is effective to signal the state of an interval of further braking-force reduction which is a function of twice the rotational moment of inertia of the wheel and after which the braking force is held substantially constant for a predetermined time.

  • Patent number: 4490128
    Abstract: An annular wheel of plastic is rotatably mounted on a central bearing. The wheel has a generally H-shaped cross-section, with radially outward and radially inward arms joined by a radial crossbar. An array of stiffening ribs at various circumferential locations around the crossbar of the H-shaped cross-section stiffen the wheel. To prevent the peripheral travel surface of the outward arm of the wheel from developing undulations during cooling following initial molding of the plastic wheel, the ribs have recesses in their opposite, axially outwardly directed sides. Dimensional relationships between the axial width and circumferential thickness of the rib, and the peripheral surface of the wheel and the thickness of the crossbar of the wheel are disclosed.

  • Patent number: 4489546
    Abstract: A friction false-twisting unit has three upstanding parallel shafts supported on a base plate. Each shaft carries a plurality of friction disks and the disks are overlapping and interleaved for applying a false twist to filament yarn drawn through the array of disks where they overlap. To damp the oscillation of the entire false twisting unit, it is fastened to the machine bed through interposed damping elements. There is a holding mandrel on the base plate which passes through a guide sleeve. The guide sleeve is, in turn, attached to the mount via the damping elements. With the false-twisting unit absent, the damping elements tilt the guide sleeve and when the unit is in place, its weight in use returns the guide sleeve to a correct orientation, so that the plane of the side of the drive whorl on one of the shafts is parallel to the plane of the tangential drive belt for that shaft where that belt passes the drive whorl.

  • Patent number: 4485617
    Abstract: A false-twist apparatus has three parallel shafts carrying interleaved sets of friction disks interconnected by drive belts for joint rotation; one of these shafts is journaled in a stationary mounting plate while the others are journaled in a carrier pivotally connected with that plate for swinging about a fulcrum offset from the three shaft axes whereby two of the disk sets can be separated to facilitate the introduction of a yarn into the intervening twisting region. A whorl on the carrier-supported shaft nearest the fulcrum is normally driven by frictional contact with a continuously moving tangential belt but is disengaged from that belt in the swung-out position of the carrier so that the disks are arrested during introduction of the yarn.

  • Patent number: 4484823
    Abstract: In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid--e.g. in a reservoir supplying fluid to a brake cylinder--forms a narrow chamber which is open at the bottom and the top and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, partial evaporation of that liquid and replacement thereof by fresh liquid from the main body results in a leveling of the temperature curve; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.

  • Patent number: 4475777
    Abstract: A split roller bearing comprises a split inner race having a radially outwardly directed inner race surface, a split outer race surrounding the inner race and having an inwardly directed outer race surface generally concentric with the inner race surface, an annular row of rollers engaged radially between the inner and outer race surfaces, and a plurality of similar roller cage parts together forming an annular roller cage lying mainly between the inner and outer surfaces and formed with respective radially opening windows receiving the rollers. The cage parts each have a radius of curvature smaller than the radius of curvature of the inner surface in an unstressed condition. Thus it is possible to provide adequate material thickness at the ends of the cage parts to prevent the cage from wearing out at these locations. Since the rollers are movable radially in the pockets there is no binding between the rollers and the cage.

  • Patent number: 4474562
    Abstract: A belt tensioner has an elongated support bar formed with a transversely throughgoing aperture and an annular inwardly directed lip around the aperture. A hardened metallic inner bearing race is centered on and elongated along a bearing axis and has one end extending into the aperture and formed with a circumferential radially outwardly open groove in which the lip is snugly fitted. An outer race is mounted on and coaxial with the other end of the inner race and is supported thereon by means of roller-bearing elements. The nonmalleable one end of the inner race does not need to be deformed to secure it in the support bar; instead the support bar, which is normally made of malleable steel, is deformed to make the connection.

  • Patent number: 4440275
    Abstract: A check valve in an automotive braking system between the master cylinder and a wheel cylinder includes a screw or a piston mounted in the check-valve housing for overriding or opening the valve prior to a charging or filling operation to facilitate an evacuation of air from the system. A flow-regulating assembly in the valve includes an annular sealing disk biased by a restoring spring into a fluid-tight contact with an annular valve seat. Another restoring spring mounted in the housing in opposition to the first spring biases a spherical plug into a fluid-tight contact with an inner rim of the disk, this disk being mounted in a cup-shaped extension of a hollow shaft. In one embodiment the shaft extends from the flow-regulating assembly to the override screw; upon an inward shift the screw engages the free end of the shaft and thereby pivots the same and the sealing disk about a point on the valve seat.

  • Patent number: 4412412
    Abstract: A thread-loading device is used in combination with a false-twist apparatus having at least one frame element having an abutment surface turned away from the yarn-twisting region defined by three sets of axially spaced rotatable twisting disks. The thread-loading device has interengaging formations on the frame adjacent the abutment surface and on the support for releasably securing same together. These formations extend radially of the region. Thus the support can be fitted to the frame by being displaced radially toward the region to interfit the formations. A detent is carried in the support and displaceable between a blocking position engaged with the arm in the outer position thereof for preventing movement of the arm relative to the support and a freeing position permitting such movement.

  • Patent number: 4408902
    Abstract: In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid--e.g. in a reservoir supplying fluid to a brake cylinder--forms a narrow chamber which is downwardly open and upwardly closed and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, a lessening of the heat conduction to the main body of liquid results in a steep rise in temperature; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.

  • Patent number: 4398774
    Abstract: In a bearing assembly supporting the free end of a drive shaft, a carrier for enabling axial motion of the assembly to accommodate thermal expansion of the shaft during extended power-transmission operations has a meandering cross-section with a thin U-shaped central or middle section and a pair of thick-walled Z-shaped peripheral sections. The sections are annular and together define a central wide groove and a pair of flanking narrow grooves. The inner Z-shaped section is attached to the outer race of a bearing whose other race is rigid with the shaft, while the outer Z-shaped section is fastened to a housing. The thin walls of the central carrier section permits a limited axial movability of the bearing assembly, while the annular shapes of the carrier sections, in particular the thick sections, inhibit axial or transverse motion of the shaft.
