Title: Non-contact parabolic spring arrangement for the suspension of motor vehicles
Inventor: SCHWEN GERHARD DIPL ING
IPC: B60G11/02
Filed: 1985-11-27
Abstract: The invention relates to a non-contact parabolic spring arrangement for the suspension of motor vehicles with a main leaf spring with at least one leaf spring and an auxiliary leaf spring lying in the same vertical plane, which are arranged and designed in such a way that the main leaf spring rests on the free ends of the auxiliary leaf spring provided with spacer elements. In order to prevent main leaf spring and auxiliary leaf spring from fanning out relative to one another under the effect of the acting lateral forces, the end areas of the spring leaf of the main leaf spring adjacent to the auxiliary leaf spring are each provided with prismatic or similar guide areas designed to match the dimensions of the spacer elements, the cheeks or the like of which areas running in the longitudinal direction of the spring, at least partially, laterally encompass the spacer elements when supporting the main leaf spring. <IMAGE>

Title: Mechanical counting device for flow measuring devices in dispensing systems for fuels, especially diesel fuels
IPC: B67D7/08
Filed: 1985-12-06
Abstract: Mechanical counting device for flow measuring devices in dispensing systems for fuels, especially diesel fuels, having a roller-type counter, which is arranged in a casing, a printing mechanism with daisy wheels and printing rollers which are eccentrically mounted in a rotary body. The roller-type counter and the daisy wheels of the printing mechanism can be reset by actuating a hand lever a single time. A form can be introduced into a form-guiding channel of the printing mechanism and, when the hand lever is actuated once again, the numerical value indicated by the roller-type counter can be printed onto the form. Each time the hand lever is actuated, a rotary movement of the rotary body through 180 DEG  can be triggered. Insertion of the form into the form-guiding channel can, according to the invention, actuate a contact switch which operates on a holding device, by means of which the form can be fixed in the form-guiding channel. The contact switch is furthermore electromechanically connected to a locking device of the roller-type counter, which device can be unlocked by means of actuation of the contact switch. There is furthermore arranged on the outside of the rotary body at least one rotatably mounted locking lever, in such a way that the form-guiding channel is locked when the hand lever has been actuated for the first time and is opened to permit introduction of a form when the hand lever has been actuated again. <IMAGE>

Title: Crank mechanism for hermetic refrigerant compressors
Inventor: GUENTHER EBERHARD DIPL ING
IPC: F04B39/00
Filed: 1985-12-14
Abstract: The invention relates to hermetic refrigerant compressors used in domestic refrigerators. The aim of the invention is to reduce the overall height of hermetic refrigerant compressors by redesigning the crank mechanism. This is achieved by virtue of the fact that a crank shaft mounted in a compact fashion in a main bearing consists simply of a length of shaft and a balance weight and that the crank pin is rigidly connected to the connecting rod, the two components being connected frictionally to one another. The invention can be used with hermetic refrigerant compressors in which the crank shaft is mounted in a compact way and which are used in low-power domestic refrigerators.

Title: Head restraint (head rest) in a motor vehicle
Inventor: MATTHIAS KLAUS DIPL ING
IPC: B60N2/48
Filed: 1986-01-09
Abstract: A head restraint in a motor vehicle is proposed, which in accordance with German Offenlegungsschrift 3,332,728 can be swivelled in a bracket between a lowered position and an in-use position, the in-use position being locked via a rotary latch which is locked by means of a locking pawl. A driving device with a power drive, a planet gear mechanism and a driving gearwheel which is driven by said mechanism and engages on the bearing elements for rotation in common is releasably flanged onto the bearing elements. Whilst the rotary latch maintains the direct locking of the head restraint, the planet gear mechanism automatically controls the locking pawl of the rotary-latch lock by the support of individual members, which changes during the sequence of movement, and, via the bearing elements, the swivelling movement of the head restraint.

Title: Sliding and guiding bushes for the gearbox in automobiles, fitted on the shift rails and shift levers
Inventor: DUSCHEK DIETER
IPC: F16H63/30
Filed: 1986-08-22
Abstract: These sliding and guiding bushes, fitted on both ends of the shift levers and shift rails in the gearbox of automobiles (VW-Audi), serve as a sliding element in the bearing bush of the gearbox. Until now, these bushes have been fitted directly in the injection mould by encapsulating the shift levers and shift rails, which with great variation in the thermal loading, after installation in the gearbox, inevitably leads to rupturing of the sliding and guiding bushes. At the same time, with this method of production there are great dimensional deviations. It is now intended to produce the sliding and guiding bushes independently of the shift levers and shift rails by the injection-moulding process in a multi-cavity injection mould, dispensing with the need for finishing work, such as deflashing of the parts, cutting off excess material or surface treatment by manual abrasion (to obtain the specified dimensions). There is also no need to insert the metal parts in the injection mould. Finishing work is the result of wear of the mould, which is caused by the metal parts not always being manufactured with precision. This injection moulding of the bushes, which can be fitted (pressed) onto the metal parts later, leads to the following advantages:   - uniform moulding cycle (precludes thermal damaging of the material)     - tolerance band is limited   - optimum surface condition - slight alteration of the mould design in the event of bush alteration.

Title: Stepping motor control
Inventor: DURST KLAUS DIPL ING
IPC: H02P8/32
Filed: 1986-04-30
Abstract: The step by step onward switching of a stepping motor by one operating rotation step (a) is carried out with two successive rotor rotation steps (m1, m2) from the rest rotation step position (s0) via a first rotation step position (s1) into a second rotation step position (s2) of the rotor of the stepping motor. In order that the rotation movement sequence (21) for the operating rotation step runs into the second rotation step position (s2) in a manner which is as flat as possible, the rotation movement sequence (21) is accelerated for a specifically determined time interval (Tb) by an acceleration step (22) which starts in the region of the first rotation step position (s1). In consequence, even in the event of relatively large tolerances of the inertia masses (flywheel masses) which are coupled to the drive shaft of the stepping motor, no significant overshoots occur when the stepping motor is in the latched state (17). <IMAGE>

Filed: 1986-05-17
Abstract: The invention relates to a seal arrangement, in particular for hydrodynamic couplings, brakes or the like. An annular gap which is located between a shaft and a seal carrier is sealed off by means of a radial shaft sealing ring from a so-called reservoir, which is at least occasionally filled by a turbulent liquid flow. The said sealing ring has an annular seal lip which can be pressed flexibly against the shaft and extends in the direction of the said reservoir. Between the radial shaft sealing ring and the radially inner region of the reservoir there is an annular shielding disc, concentric with respect to the shaft. The intermediate space existing between the radial shaft sealing ring and the shielding disc is open in the radial direction towards the radially outer region of the reservoir.

Title: Remote-controllable hydraulic control device
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B13/10
Filed: 1987-03-07
Abstract: What is proposed is a remote-controllable hydraulic control device (10), the longitudinal slide (17) of which can be actuated by a connectable hand-control device (12) in the event of a failure of the remote-controlled lifting magnets (14, 15), so that, during remote control, no frictional influences of the hand-control device (12) have to be overcome. A rack (38) coupled to the longitudinal slide (17) forms, with a gearwheel (44) on a hand lever (41) mounted rotatably and longitudinally movably, a disconnectable and connectable rack gear, the gearwheel (44) of which is brought into engagement with the rack (38) by pressing the spring-centred hand lever (41) in its longitudinal direction and deflects the rack as a result of a subsequent pivoting of the hand lever (41) about its axis of rotation (43). Consequently, if auxiliary energy fails, sensitive control is possible for safety reasons in the mobile hydraulics. <IMAGE>
