Patent DE-3838556-A1 (DE)
Inventor: ECKARD ALFRED
IPC: B21B13/10
Filed: 1988-11-14
Abstract: A continuous rolling train, in particular a universal roll stand tandem train in a profile tool steel rolling mill, comprises a plurality of roll stands 1 each displaceable by a displacing unit 9 transversely to a rolling line 2 to a transfer station, which is offset relative to the rolling line and in which the displaced stand can be coupled with an automotive tractor 14. The coupled stand 1 is movable by the tractor 14 from the transfer station to a changing stage 21, which itself is movable parallelly to the rolling line 2. The stand 1 can be arrested at the changing stage 21 and uncoupled from the tractor 14, the tractor then being movable into a waiting station 27. Subsequently, an exchange stand 22 brought onto the changing stage 21 can be moved by the tractor in reverse sequence back to the transfer station. <IMAGE>

Title: Method for controlling heat pumps
Inventor: KUEMMEL GERD
IPC: F25B47/00
Filed: 1989-04-05
Abstract: Control of a heat pump having a compressor, evaporator and condenser as well as two voltage-controlled conveyor motors for media of differing temperature, in which decreasing current of the compressor motor is measured as manipulated variable in the case of incipient icing and rising current in the case of overheating and is used via a positioning motor driving in the opposite direction to adjust the voltage regulator which in the case of a decreasing compressor motor current increases the output of the conveyor motor conveying warmer medium and reduces that of the conveyor motor conveying colder medium, with the result that the warmer medium flows out of the evaporator cooled less or warmer than before and counteracts the icing, while overheating is met by oppositely directed control of the output of the conveyor motors, with the result that medium which is not so warm is driven into the evaporator and colder medium is driven through the condenser.
