Title: Dressing device for abrasive wheels for the flange-side grinding of the outer rings of cylindrical roller bearings
Inventor: EICHLER ARNFRIED
IPC: B24B53/065
Filed: 1988-06-01
Abstract: The invention relates to a dressing device for abrasive wheels for the flange-side grinding of the outer rings of cylindrical roller bearings. A two-side dressing device is formed by two rods which are constructed as pinions at their lower end. The pinions engage in hydraulically linearally moved tracks, it being possible for the path of the linear movement to be limited. With the limitation of the linear movement, at the same time the pivoting angle of the dressing diamonds is defined. Once the preselected end position of the positioning device is reached, the dressers perform a circular pivoting movement for relieving the abrasive-wheel sides.

Title: Control arrangement for a hydraulic servomotor
Inventor: MEIER DIETMAR
IPC: F15B11/05
Filed: 1988-06-29
Abstract: A control arrangement, simple in terms of circuitry and construction, for a servomotor has a pressure-medium pump (13), a 3/4-way directional control valve (14) with proportional magnet (19) and restoring spring (20), and a 2-way flow-control valve, acting as pressure balance, at (40). The control spool (18) of the directional control valve (14) can be displaced from a neutral position established by the restoring spring (20) into three positions, specifically a centre position, a "lifting" position and a "lowering" position. In the neutral and centre position, the pressure-medium flow delivered by the pressure-medium pump (13) is conducted in short circuit via feed and return connection (P, T) of the directional control valve (14). In the "lifting" position, the pressure-medium flow is directed to the servomotor (10), in the course of which the pressure difference dropping at a sharp-edged orifice (38) is applied to the inlets (42, 43) of the flow-control valve (40) to regulate the pressure-medium flow independently of load. In the "lowering" position, the pressure-medium flow is directed in a choked manner from the servomotor (10) and to the return (25) (Fig. 1). <IMAGE>

Abstract: In a mechanical drive for a supercharger of an internal combustion engine a rotor (3) fixed on a rotor shaft (2) is driven by the crankshaft of the internal combustion engine by way of a variable speed gear (4), a solenoid-operated separable coupling (6) and a transmission. In order to create favourable overall dimensions for the supercharger drive in its axial and radial extent and a good bearing for an input shaft (9) of the transmission, the transmission is designed as planetary gearing (7), the input shaft (9) being supported in an axially projecting flange (16) of the transmission housing (13) and the solenoid-operated separable coupling (6) being arranged on the circumference of the said flange (16). It is proposed that a coupling plate (15) be arranged on one side of the said bearing (17) and on the other side an internal gear (18) on the input shaft (9). <IMAGE>

Title: Wheel suspension of a steerable vehicle wheel
Inventor: HAJTO JENOE
IPC: B60G15/06
Filed: 1988-12-23
Abstract: In a known wheel suspension a self-aligning torque independent of the axle parameters is produced by a spring element supported directly on the wheel carrier, as a result of which the steering behaviour is adversely affected. Furthermore in known double-wishbone axles with increased longitudinal suspension a greater wind-up effect of the wheel carrier occurs when braking. Finally it has hitherto not been possible with such axles to optimise both the wheel suspension kinematics and the steering geometry. The new wheel suspension is intended to rectify the said disadvantages. For this purpose the spring element (40) is articulated on a transverse link element (20) rotating during the steering process so that the articulation (44) of the spring element (40) moves on a circular path and in so doing raises the vehicle by way of the spring element. In addition the damper tube (51) is connected by way of an arm (17) to an upper transverse link (10), which is aligned approximately parallel to the vehicle longitudinal direction (85). The wheel suspension can be used for the front axle of passenger motor vehicles. <IMAGE>

Title: Device for anchoring structural elements on a load-bearing anchorage base
Inventor: KETTNER RICHARD DIPL ING
IPC: E04B2/94
Filed: 1989-03-30
Abstract: The anchorage device which is intended, in particular, for anchoring parapets or wall claddings, e.g. in the form of concrete panels or natural-stone panels or facing masonrywork comprising fair-faced (frost-resistant) bricks, has an anchorage element, which can be fastened on or in the anchorage base, and a connection part which juts out from said anchorage element from the side remote from the anchorage base in the installation position and which can be connected to the structural element to be anchored or can be embedded therein. Arranged between the anchorage element and the connection part is a bearing which, in the direction transverse to the load, permits displacement movements between said two anchor parts and, in contrast, is rigid in the load direction. This bearing may, in particular, be a plain bearing. In a preferred embodiment, the plain bearing exhibits at least one slide pin which is connected fixedly to the anchorage element or the connection part, passes, with play, through the respectively other anchor part, in a transverse cutout, and receives transversely movably with respect to the anchor part provided with the slide pin. A particularly simple plain-bearing embodiment has two slide pins arranged at a distance from one another.
