摘要:
A control device has a base plate, a cover plate coupled to the base plate, a cavity formed between the base plate and the cover plate, a circuit carrier disposed in the cavity, and a conducting track carrier electrically coupled to the circuit carrier. The base plate has a continuous recess that is configured and arranged for feeding a casting compound into the cavity between the base plate and the cover plate. The casting compound is embodied to at least partly enclose the circuit carrier and/or the conducting track carrier in a vibration-damping manner.

The invention relates to a device for heating rod-type, metallic work pieces, comprising two heating modules that are switched one behind the other, which are coupled with one another by way of a control module, so that a continuous heating chamber is formed, whereby the first heating module is formed by a gas oven (1), and the second heating module is formed by an induction oven (2).

A device for inductive billet-heating includes a single or multi-layer billet-heating coil (4) for a round billet (5), in which the billet-heating coil (4) is made up of one or more consecutive, galvanically separated zones. The zones are supplied with electrical energy from a three-phase network by means of an electrical switching device and a control unit. The billet-heating coil (4) includes multiple, synchronically regulated zones (Z1, Z2 through Zn) with reference to frequency and phase of inductive field. For a current feed to each zone (Z1 through Zn) of the billet-heating coil (4), a converter (2) with variable frequency and a plurality of modules is provided. The converter includes plurality of power-moderate closed units with DS-network feed and synchronization of phase and frequency of an output voltage.

A controller for a motor vehicle with an automatic transmission is connected to sensors in the transmission and through a communications channel to an engine controller. A gear ratio is varied with actuators for actuating final control elements in the transmission. The transmission and the electronic transmission controller are constructed as an integrated complete system, which includes all of the mechanical, hydraulic and electronic transmission components. A plug forms a pressure and fluid-tight connection between the transmission and the transmission controller secured to a transmission housing.

In order to improve a method for determining the quickly changing, average temperature of a flow of compressible medium such that it is possible to ascertain sudden changes in temperature accurately and with the least possible delay in time, it is suggested that the medium be caused to flow through a throttle point, that the mass flow of medium flowing through the throttle point be determined, that the pressure inside and upstream outside the throttle point be ascertained and that the average temperature be determined on the basis of the mass flow and the pressure inside and outside the throttle point.
