Abstract: A bearing assembly for bearing a steering shaft includes a bearing housing, a bearing, and a damping disk. The housing has two housing sections. The bearing is integrated into the damping disk. The damping disk is positioned so that an inner wall of a first housing section radially supports a circumferential side of the damping disk, and such that a second housing section is axially supported by the damping disk.

Abstract: A roller bearing assembly for supporting a shaft axially and radially in a rack includes a roller bearing with a carrier, a portion of which is supported at the rack with an element with elastomeric properties being interposed between a support for the rack and the portion of the carrier. In order to indicate a roller bearing, which supports the shaft axially and radially, and makes an inclined position of the shaft possible without causing straining of the system of shaft, roller bearing and rack, the element with elastomeric properties, viewed in the tangential (circumferential) direction of the roller bearing, has at least a first region, the stiffness of which is different from that of the remaining tangential (circumferential) region.

Abstract: A power-steering system, e.g., for a motor vehicle, having an electric motor, which transmits a steering-assist force via a belt transmission to a ball-screw transmission for displacing vehicle wheels, includes a cam, via which the ball-screw transmission and/or electric motor is supported in a steering-gear housing. The tension of a belt of the belt transmission is adjustable by rotating the cam in the steering-gear housing. The cam has at least one cutout on the circumference, and/or the steering-gear housing has at least one cutout in its inner wall. A locking element may be inserted into the cutout, in order to fix the cam in position with respect to the steering-gear housing. After being inserted, the locking element is operatively connected to the cam and the steering-gear housing.

Abstract: A power steering system with a circulating ball spindle mechanism, an extending element of the circulating ball spindle mechanism being support rotatably over a bearing and the bearing of the element making possible a swiveling motion corresponding to the direction of action of interfering forces.

Abstract: A steering system with an electric motor includes a hollow shaft through which a rod is passed, the rod being drivable in the longitudinal direction by the electric motor through a worm gear. An intermediate transmission is provided, which reduces the rpm of the electric motor. The hollow shaft is connected torque-proof with a driving outer contour, which transfers torque to the intermediate transmission. The intermediate transmission has a first gear wheel, an axle of which is supported so as to be stationary, and the outer contour of which transfers torque. The worm of the worm gear is formed on the rod. A nut of the worm gear is drivable by the intermediate transmission. For greater economy of construction of the steering system, a second gear wheel with a torque-transferring outer contour, connected over an intermediate shaft torque-proof with the first gear wheel. The intermediate transmission transfers torque to an outer contour, which is connected torque-proof with the nut.

Abstract: An indentation hardness test system includes a frame including an attached indenter, a movable stage for receiving a part attached to the frame, a camera, a display, a processor and a memory subsystem. The camera captures images of the part, which can then be provided on the display. The processor is coupled to the movable stage, the camera and the display, as well as the memory subsystem. The memory subsystem stores executable code that instructs the processor to capture a series of real-time images of the part using the camera, obtain associated stage coordinates for each of the images and display a composite image, which includes the series of real-time images assembled according to the associated stage coordinates, of the part.

Abstract: The invention relates to a method for producing 1,1′ binaphthalenylidene-4,4′-diones of general formula (I), wherein R1 represents C1-6 alkyl, C1-6 alkoxy, phenyl, substituted phenyl, benzyl or benzyloxy; R2, R3, R4, and R5 independently of one another represent hydrogen, C1-6 alkyl, C1-6 alkoxy, phenyl, substituted phenyl, benzyl or benzyloxy. Production takes place by oxidative coupling of the corresponding naphthols in the presence of a peroxide and a precious metal catalyst.
