Abstract: In order to achieve an optimal pressure build-up function in an anti-lock braking control system for automotive vehicles and to maintain the pressure at the optimal point for long periods of time and thus achieve better brake deceleration with greater stability of travel and greater comfort than with conventional ABS control systems, the anti-lock braking control system includes, in addition to the ABS controller and monitoring circuit (3), a pressure function generator (4) which, for each wheel, intermediately stores an intermediate brake pressure value whenever wheel overbraking has been noted. Then, in the pressure build-up phase, the pressure function generator (4) gives off a signal to the pressure modulator in order to increase the wheel brake pressure in accordance with an exponential function.

Abstract: A method for controlling the braking force of motorcycles, which includes storing the vehicle deceleration value which was measured when a lift-off signal occurred as an optimal deceleration limit value and reducing the braking force applied to the front brakes if the motorcycle deceleration approaches or exceeds this limit. A lift-off signal is generated if after a predetermined time from the initiation of a braking cycle, it is determined that the rear wheel has lost adherence to the grounds.

Abstract: In a method for regulating the braking force of motorcycles, the wheel circumferential speed is detected by sensors and evaluated by a microprocessor which gives a signal off to a pressure modulator if given limit values of deceleration are exceeded in positive or negative direction (locking signal) and if, within a predetermined period of time, a signal which symbolizes ground adherence of the rear wheel does not occur (lift-off signal), whereupon the pressure modulator reduces the pressure in the front brake circuit.

Abstract: An antifriction bearing with an outer ring having a main groove in its periphery. The groove has sharp edges which engage the interior of a housing surrounding the outer ring. Alternately, a secondary groove may adjoin an axial side or both axial sides of the main groove. A deformable material ring having its own radially outwardly facing deformation remitting groove may be disposed in the main groove in the outer ring. The deformable ring protrudes radially out of the main groove to be deformed by the internal wall of the housing around the bearing.

Abstract: To remove oil from an antifriction bearing, an annular space is defined between the outer and inner rings next to the row of bearing elements. A stationary part is at the inner ring. An oil discharge hole passes through the stationary part. An oil guide plate having an obliquely inclined baffle plate part extends partially around the rear side of the discharge hole and up into the annular space from the stationary part to guide oil into the discharge hole.

Abstract: A frictional false twisting unit including a plurality of driven shafts, a driven pulley on one of the shafts, an externally arranged motor with a drive shaft, an endless loop toothed belt between the drive shaft and the driven pulley. The shafts are on a carriage or base plate which is moveable or swingable with respect to either the motor or a base plate on which the motor is disposed. The shaft carrying base plate or carriage is movable to slacken the toothed belt, enabling removal of the driven pulley from the toothed belt and removal of the shafts from the unit. The thread monitoring devices of the unit remain with the unit while the shafts are removed. Channels for the lateral runs of the toothed belt prevent excessive spread of the belt when it is slack and when the driven pulley is removed. A guide beneath the belt prevents the belt from moving down axially when the belt is slack and the driven pulley is removed.

Abstract: A wheel bearing unit for vehicles having a speed of rotation detector. An inner ring of the wheel bearing unit is mounted on an axial shoulder of the wheel hub. The inner ring is retained axially by a bead formed by plastic deformation of the rear end of the shoulder. Elevations protrude axially rearwardly around the circumference of the bead. An axial depression into the rear of the hub at the hub axis. The passage of the elevations are sensed by a rotation detector spaced from the rear end of the hub.

Abstract: A gauge for measuring the thickness of an unsupported web. One triangulation sensor is located above and the other is located below the web. Each triangulation sensor includes a laser whose beam is bounced off the web to a position sensitive detector in the sensor, which determines the distance of the surface of the web from the sensor. The sensors travel in synchronization along tracks, across the direction of web travel. To detect and compensate in the measurements for any sag or deflection in the track, there is a further laser either on one of the sensors or on the frame of the gauge and a respective further detector on the other one of the sensors and/or the frame of the gauge. The further detector detects the shifting of the sensor toward or away from the web and generates a signal which is combined with the triangulation signals from the sensors to calculate the thickness of the web.

Abstract: To produce an inexpensive small size ball bearing, the inner ring races are formed of spherical segments which are connected to each other at flattened connection places. A row of balls is guided by a respective inner ring race contact point on each of the segments in the region of the attachment place between two segments. In a four point ball bearing, the single row of balls contacts two contact points, one on each spherical segment, that define the inner race and contacts two races formed in the outer ring. In a three point bearing, there are two axially spaced apart rows of balls and three spherical segments in an axial row, two of the spherical segments of the inner ring define two of the inner race contact points for one of the ball rows and two other spherical segments of the inner ring defined two of the inner race contact points for the other row of balls. In both embodiments, the outer ring is split into two parts, each having one contact point on it.

Abstract: In a mounting for disk spindles, an embodiment is provided in which, despite simple construction and simple assembly of the bearing, a high degree of precision is obtained. The angle ball bearings in O-arrangement have outer rings (4) the race (4') of which has, in longitudinal section, a radius the center point (7) of which lies on the axis of rotation (8) of the inner races (2).

Abstract: A two row angular-contact roller bearing having on undivided bearing ring and one axially divided bearing ring with a respective row of rolling elements rolling over each of the axial sections of the divided ring. The respective comb separator for each of the rows of rolling elements has an annular collar that projects axially toward the annular collar on the other separator. One separator annular collar is radially inclined inwardly and the other separator collar is radially inclined outwardly. The collars are so placed as to interfere, and they are sufficiently flexible as to deform and upon the collars being pushed together for causing the collars to loosely interlock sufficiently to enable one row of rolling elements and their separator to rotate with respect to the other. Elevations defined on the divided race ring sections support the axially inward sides of the rows of rolling elements. A shoulder on the divided race ring section engages the axially outward side of the row of rolling elements.

Abstract: To achieve a dependable axial fastening of a flat cylindrical outer surface of the outer ring of a double row angular anti-friction bearing inside the smooth internal surface of the bore of the external housing in which the outer ring is disposed, the races for the bearing rolling elements, and which are either balls or tapered rollers, are oriented so that the resultant lines of bearing force extend from the rolling elements, converge and intersect the outer surface of the outer ring. The resultant lines of force converge at or radially outward of the outer surface of the outer ring. A respective pair of interruptions, in the form of annular grooves around the outer surface of the outer ring, and having sharp transition edges with the outer surface of the outer ring, are defined at both axial sides of and near to the intersection of a resultant line of force with the outer surface of the outer ring.

Abstract: A bobbin holder for a textile spindle. A spindle having an upper part with opposite double flat surfaces and with a bottom surface. An upper adapter for placement around the upper part of the spindle, the adapter having a recess in it adapted to the shape of the upper part of the spindle, such that at one rotation orientation, the upper part of the spindle core is aligned with and is in the adapter recess and at other rotation orientations, the upper part of the spindle is out of the adapter recess. There is an upper adapter with a conically tapered bobbin receiver and an opposed lower adapter also with a conically tapered bobbin receiver which are both conically tapered to be received in the opening in the bobbin. A spring in one of the top and the bottom adapters biases the respective conical receiver toward the other conical receiver for securing the bobbin between the two conical receivers.

Abstract: A mounting sleeve particularly for the loose annular parts of a multi-row anti-friction bearing wherein the rows of rolling bodies are toward the axial ends of the outer ring. The mounting sleeve is approximately U-shaped with a slit opening of about 90.degree. in it extending along the sleeve. At axially opposite ends of the U-shaped sleeve are formed radially inwardly directed flanges which extend over a smaller circumferential angle than the sleeve, e.g. over an angle of about 180.degree., and are each symmetric around the U-shaped sleeve. Projections on the axial insides of the flanges rest axially either against the row of rolling bodies or against the separators for the row of rolling bodies. A radially outward projection opposite the slit opening in the sleeve aids in installation and removal of the sleeve.

Abstract: A cage, particularly for needle bearings, is an annular ring of springy cage material and has a slit extending completely through the cage. The opposed, separated ends of the cage at the slit are joined by a pair of elastic connecting arms which are each approximately of V-shape and having vertices which extend axially and either face toward each other or face away from each other, which permits circumferential shifting and inhibits relative axial shifting of the separated cage ends and prevents overlap at the cage ends.

Abstract: A seal for closing the radial space between two coaxial, radially spaced, relatively rotatable parts. Each of an axially inner and an axially outer sealing ring comprises an approximately L-shaped metal part having sealing lips of elastic plastic material arranged on it. The axially outer sealing ring seated on the radially inward part has a first sealing lip which faces either the interior of the radially outward part or the axial leg of the axially inner sealing ring. To prevent contamination of that first sealing lip, the outer sealing ring has an obliquely outwardly directed fling lip which is radially inward of the first sealing lip and extends approximately into the region of a plane determined either by the axially outer front surface of the axially outwardly extending leg of the inner sealing ring or of the radially outward part. The first sealing lip may also have an obliquely outwardly directed extension located radially inwardly of and extending axially outward of the first sealing lip.

Abstract: A seal for a thread drive including several ring parts arranged one within the other, to provide a dependable and compact unit comprised of a few parts. A sealing ring which surrounds and rests against the threaded spindle is comprised of rigid plastic. The sealing ring is a single thread section with axially separated ends which are integrally joined together by a transverse connection which closes the thread gap between the separated ends. A pretensioned tension ring surrounds the sealing ring. A housing ring surrounds both other rings. A wiper or scraper may be located on the sealing ring opposite the transverse connection.

Abstract: A multiple-coordinate measurement sensor has an improved, high degree of precision of measurement, even at higher measurement speeds. Three multiple-axis guide systems (7,13,19; 8,14,20; 9,15,21) are arranged in parallel to each other. Length-measuring devices (6) and zero-point and contact-force generators (5) of each system are fastened to the reference base (1), and the devices (5,6) detect the positions of the guides (7,8,9) which are closest to the reference base (1).

Abstract: An anti-friction bearing unit, particularly for use in an exhaust gas turbo charger. The unit includes two anti-friction bearings axially spaced apart from each other on a shaft. High temperature occurs on one end of the shaft. A precise mounting is provided which is not sensitive to high temperatures on at least the axial side exposed to high temperature. The bearing outer ring, which is the ring not subject to high temperatures, consists of one piece. The bearing inner ring is widened and divided into two sections at its axial middle. The axial portion of the divided inner ring which is exposed to high temperature consists of material of high heat resistance. The high heat resistance material is, for example, 80 MoCrV 42 16 (M 50) or X 102 CRMo 17 (AISI 440 C). An additional intermediate ring around the shaft at the high temperature and helps reduce heat transmission.
