Abstract: A servo-steering system for vehicles, especially for motor vehicles, in which the steering lever is displaced by means of a steering nut movable on a steering spindle, and in which adjusting devices are coordinated to the steering nut which are acted upon by a pressure medium whose pressure is controllable by means of control elements as a function of the deflection of the steering nut; a high pressure accumulator thereby serves as pressure medium source whereby the inflow of the pressure medium to the spaces containing the working pressure at the control element is completely interrupted in the normal rest position of the steering nut.

Abstract: A pressure control valve for incompressible media, particularly for automatic motor vehicle transmissions, which is constructed as solenoid valve and in which the medium is conducted through a valve gap formed by a valve seat and a valve closure member; the valve closure member is acted upon by a force dependent on the control magnitude, especially on the magnitude of the torque; a predetermined force, produced by a force storage device, such as a spring, acts in the de-energized condition on the valve closure member connected with the armature of the magnet whereby the force is adapted to be varied by energization of the coil in dependence on the control magnitude; the iron casing surrounding the energizing coil terminates in two cylindrical pole shoes disposed concentric to one another and enclosing a ring-shaped magnet gap, whereby the armature carried by the armature support is attracted between the pole shoes with a more or less strong force depending on the coil energization; the armature support is the

Abstract: A method for reducing harmful stresses in layers, particularly ceramic layers such as aluminum oxide, chrome oxide or nickel oxide and calcium fluoride applied by thermal spraying on metallic structural parts in which the applied layer is subdivided in planes extending generally perpendicularly to the layer surface by partition members.

Abstract: Equalizing and air separation tank structure for accommodating separation of air from a liquid heat carrier flowing through a cooling system for an internal combustion engine cooling space. A pair of separation chambers are provided in series connection with one another and one above the other, both having separate vents opening to an air chamber space arranged thereabove. The upper separation chamber includes an inlet opening for a portion of the flow through the circulatory system and the lower separation chamber includes an outlet for such flow, which outlet opens adjacent a main flow outlet which accommodates passage of the remaining portion of the coolant flow in bypassing relationship to the separation chambers. The main flow inlet to the tank opens into a main flow chamber, which also includes a separate bypass vent leading to the air chamber above the separation chambers.

Abstract: A mixture-compressing reciprocating-piston internal combustion engine with two separate cylinder rows and a single mixture-producing device, in which one row is supplied with a slightly richer air/fuel mixture from a common mixture-producing device which is then leaned down by the admixture of additional air while the other cylinder row is supplied with an air/fuel mixture which is as accurately as possible stoichiometric; oxygen probes are thereby used upstream of the respective catalysts to control a valve controlling the additional air inlet to the one cylinder row and the fuel supply to the mixture-producing device.

Abstract: A control member for a clutch disk of motor vehicle main clutches in which a disk member carrying the friction linings and a lateral member rigidly connected therewith are operatively torsionally elastically connected with the flange of a hub member; several springs or spring sets of different characteristics are thereby retained in the windows of one of the two parts torsionally elastically connected with each other and engage in windows of the other part while frictional damping devices are provided, whereby the start of opertion of at least one damping device is determined by a control member which engages with tabs, arms or the like in the windows intended for the accommodation of the springs or cooperates with the spring ends; the control member includes an approximately radially extending fork-like arm whose two fork ends are bent over along their radial edges, as viewed in the axial direction, and therewith enclose a control spring; these bent over portions are supported at their radial inner ends with

Abstract: A steering system for motor vehicles, especially for passenger motor vehicles in which parts of the front section are so constructed that they act on parts of the steering linkage in the sense of blocking the steering in case of a displacement of these parts of the front section in the direction toward the passenger space which displacement is caused by a front-end impact or front-end collision.

Abstract: A roof for a motor vehicle, particularly a passenger motor vehicle which possesses an area to be opened intermediate the windshield and a roll-over girder disposed within the area of the rear window; the area to be opened in the roof is subdivided into two sections which are adapted to be displaced telescopically and can be retracted one within the other into the area of the roll-over girder so as to be completely covered by the outer member of the roll-over girder; the roll-over girder together with the outer covering member thereby preferably forms a hollow body.

Abstract: A control of a linkage for a foldable top of motor vehicles which is pivotally mounted at brackets arranged in recesses; the linkage, in the folded-together condition of the roof is accommodated in a closed off top compartment; in the course of its unfolding operation, a roof column which begins to erect itself, displaces a curved fabric-retaining bar forming the rear termination of the top upwardly by way of an entrainment mechanism; the entrainment mechanism which is formed in the manner of a quadrilateral joint system consisting of guide members, a lever, a guide lever and fabric-retaining member, is movably supported at the bracket by way of the lever and the guide lever; a connecting lever thereby pivotally connects the quadrilateral joint system at the free end of the roof column.

Abstract: A drive arrangement for the auxiliary aggregates of a motor vehicle equipped with an internal combustion engine which includes an electrical power supply system with a generator and a battery; only those auxiliary aggregates which have a power requirement dependent on the rotational speeds are thereby driven from the internal combustion engine as heretofore whereas all auxiliary aggregates which have a power requirement independent of the rotational speed are driven in common from an electrical motor operating at substantially constant rotational speed and fed from the electrical power supply system; a thermionic converter operable by means of the fuel of the motor vehicle is thereby provided as generator.

Abstract: An exhaust gas catalyst mounting, especially for motor vehicles, which so clamps a catalyst body in an exhaust line that it is protected against exhaust gas oscillations and/or vehicle vibrations; the mounting of the catalyst body inside the exhaust line being elastic in both the radial and axial directions.

Abstract: A motor vehicle, especially a military vehicle, which is provided with a relatively narrow boarding entry directly surrounding the body of the driver and with a warning system for indicating the failure of auxiliary aggregates and/or of auxiliary media; a mechanical central warning device is connected in parallel with a central warning lamp which lights up each time an individual one of several warning lamps lights up, each indicating a predetermined failure; the mechanical warning device thereby transmits to the driver the warning by an increase in the pressure which must be exerted by the driver on the gas pedal for purposes of its displacement.
