Abstract: A steering mechanism with time derivation wherein a servo member dependent upon an angular velocity of a steering wheel is connected in the manner of a gear system by means of a summing gear mechanism with a servo member dependent on an angle of the steering wheel turn and also with a servo member dependent on an angle of the wheel turn of steered vehicle wheels. A gear element of the summing gear mechanism pertaining to the servo member dependent on the angular velocity is supported toward a housing by way of a resilient support. The servo member dependent on the angular velocity is positively turned off with respect to its action on the summing gear mechanism if the steering wheel angle exceeds a specific limiting angle.

Abstract: A self-locking differential gear for motor vehicles with locking devices for automatically locking the differential gear, which are coordinated to each driven gear; a mechanism in the form of a torque scale is thereby coordinated to each driven gear which in case of a force equilibrium, retains the respective locking device in its ineffectual position and transfers the same automatically into its effective position during a disturbance of this equilibrium.

Abstract: To securely avoid any gap formation between a ring mount barrier and adjoining parts of the floor of an articulated vehicle such as a bus, a safety cover construction is carried by a turntable coupling for supporting the ring mount barrier. The safety cover construction has a U-shaped transverse cross-section defining a receiving space for receiving a lower end of the ring mount barrier with upper free ends of legs of the U-shaped cross-section in engagement therewith. The safety cover construction is formed of an elastic material, such as rubber or synthetic plastic, and thus is able to remain in engagement with the ring mount barrier despite changes in pitch and bending angles between portions of the vehicle articulated by the turntable coupling. To further assist in retaining the upper ends of the legs in engagement with the ring mount barrier, according to a preferred embodiment, a spring steel reinforcement may be embedded within the legs.

Abstract: A process and arrangement for introducing a material such as a foam into automobile body cavities for at least one of noise insulation or increased rigidity. The cavities may be provided with open spaces or be adapted to only be partially filled with the foam. A bag is initially introduced into the cavity with the bag being provided with a filler opening. The volume capacity of the bag corresponds approximately to the volume of the automobile body cavity or a portion of the body cavity which is to be filled with the foam. A mixture of expandable components is introduced into the bag and, following an expansion reaction or a setting, the foam fully fills the bag.

Abstract: A bi-mobile mechanically trackable road vehicle which includes a steerable axle having steerable wheels and at least one additional unsteerable axle having unsteerable wheels. Tracking transverse guide rollers are provided in an area of the vehicle axles. The non-steerable axle is mounted in the manner of a turntable so as to be freely pivotable about a vertical axis with an arrangement being provided for automatically selectively rocking the at least one non-steerable axle in an exact transverse position when the vehicle leaves a guide track and for automatically unlocking the non-steerable axle upon an entry of a vehicle onto the guide track. At least one of the transverse guide rollers is mounted so as to be freely transversely displaceable within mechanical preset limits.

Abstract: An injection valve arrangement for a high-pressure injection of liquid fuel into a working chamber of an internal combustion engine with the arrangement including at least one valve needle which is urged by a spring force in a closing direction so that a pair of sealing cones associated with the valve needles are brought into engagement with a pair of separate valve seats.
