Abstract: ABSTRACT OF THE DISCLOSURE           An arrangement for adjusting the mass of gobs thermoplastic material, especially molten glass, which are deformed in a positive manner in the mold of a molding ma-chine by means of a pressing member which penetrates into the gobs.  A distance transducer mechanically detects the maximum depth of penetration reached by the pressing member during each molding-machine operating cycle.  The distance transducer is connected with a metallic actuating element for a differential transducer, at whose output is produced an electrical signal proportional to the maximum penetration depth reached, this signal being applied to an automatic regulating circuit which adjusts the setting of a dosing structure which controls the mass of the gobs.  The regu-lating circuit includes, at the output of the differential transformer and connected one after the next, a measurement transducer, a maximum-value storage, a sample-and-hold cir-cuit, a summing junction, a PI- or PID-regulator and an ad-justing motor which drives an adjusting member for the dos-ing structure, as well as a feedback transducer.  The feed-back transducer is connected to the PI- or PID-regulator via a rotary-angle-to-voltage converter.  A control and display panel is connected to a control logic circuit, the latter connected to the maximum-value storage and to the sample-and-hold circuit, the control logic circuit receiving a machine synchronization signal once per machine operating cycle.  A desired-value potentiometer furnishes a desired-value voltage representing the optimum penetration depth for the pressing member, this voltage being applied to the summing junction.  A weighting circuit can be provided to take into account the different maximum diameters of differ-ent pressing members which may from time to time be used.          The feedback transducer is automatically returned to a mid-dle angular setting thereof.  The distance transducer can be constructed in several different ways, disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           An independent rear wheel suspension for passenger motor vehicles, with a wheel carrier being held through upper and lower wishbones and guided by way of a track rod, offset with respect to an axis of rotation determined by points of articulation of the upper and lower wishbones on the wheel carrier. The track rod engages the wheel carrier and extends in a transverse direction of a vehicle. Respective wheel carriers are pivotable under an influence of a longitudinal force acting on the respective wheels about an instantaneous center of rotation, present in a side view of the wheel suspension, due to the fact that elastic resilience is provided in at least one of the connections to the vehicle body formed by the wishbones. Positions of the track rod and the instantaneous center of rotation of the wheel carrier are coordinated with one another in such a manner that, during a braking of the vehicle the wheel carrier is pivoted in a toe-in direction and/or, during a starting of the vehicle, the wheel carrier is pivoted in a toe-out direction.
