Abstract: A method and a device for closed-loop control of an electrode gap in a vacuum arc furnace subjects an electrode gap of a melting electrode from the surface of a melt material to closed-loop control as a function of a droplet short-circuit rate. For this purpose, a histogram of detected droplet short-circuits is created on the basis of at least one droplet short-circuit criterion. The histogram is subdivided into sub-areas, a characteristic sub-area of the histogram is selected for closed-loop control purposes. The electrode gap is subjected to closed-loop control on the basis of the droplet short-circuits which can be associated with the selected sub-area.

Abstract: A drive train of a vehicle is disclosed which comprises a permanently driven primary axle and a secondary axle connectable to the primary axle via a switch-on device with a switch-on mechanism, whereby the secondary drive train output via side shaft couplings is transferred to the drive wheels of the secondary axle. Because the switch-on mechanism and/or the side shaft couplings have frictionally engaged couplings, it can be that when the secondary axle is uncoupled, the shutdown section of the secondary drive train located between the switch-on device and the side shaft couplings is uncoupled both from the primary axle and from the secondary drive wheels, such that there is no more power loss in this shutdown section, whereby connecting the secondary drive train during travel is possible all the same and losses in comfort and practicability do not have to be tolerated.

The input shaft extends in a longitudinal direction. The drive unit comprises a power-split device, of which the input member is connected to the input element and of which the output members are connectable to driveshafts of the axle. The axle is oriented in a direction transverse to the longitudinal direction. The input member and the output members of the power-split device are mounted rotatably about axes parallel to the longitudinal direction.

Abstract: A drivetrain for a motor vehicle has a friction clutch for transmitting drive torque for the motor vehicle and has an actuator arrangement for actuating the friction clutch. The actuator arrangement has a first actuator which is designed to close the friction clutch quickly with little force expenditure in order to thus quickly close up the play which is present in the open state of the friction clutch. The actuator arrangement has a second actuator which is designed such that, with a small stroke, it applies a large force for actuating the friction clutch in order to keep the friction clutch closed with little energy expenditure.

Abstract: The invention relates to a drive train of a vehicle, comprising a permanently driven primary axle and a secondary axle connectable to the primary axle via a switch-on device with a switch-on mechanism, whereby the secondary drive train output via side shaft couplings is transferred to the drive wheels of the secondary axle. A disadvantage to these drive trains is that also when the secondary axles are not connected their components are dragged along by the vehicle drive or by the drive wheels rolling away on the roadway, causing power losses. Complete shutdown of the secondary drive train to date is executed only by manually switchable wheel hub couplings which are however a disadvantage with respect to ease of use and practicability.

Abstract: The invention relates to a system and method for programming an automation system. To avoid conversion errors and to guarantee data during the programming of an automated system, a graphic description by means of pulse timing diagrams is used to generate a program of the automation system, in particular the program of a memory programmable control. Modifications of the pulse timing diagrams thus lead directly to modifications of the program of the memory programmable control, without the need for a renewed conversion that potentially contains errors.

Abstract: A technical system is described by several abstract or concrete models which have a mutual relationship. Information/attributes can be associated with model elements and “inherited” through these relationships. While the approach can basically be applied to different types and models of machines, it is described more particularly for hierarchical component models. Model elements in these models are referred to as components, assemblies, etc.
