  • Patent number: 9056752
    Abstract: A crane comprising a diesel-electric drive, the three-phase generator of which supplies an AC voltage circuit, further comprising a DC voltage circuit connected to the AC voltage circuit, electric motors which drive at least one rotating mechanism, a lifting mechanism and a luffing mechanism of the crane, at least one brake resistor, and a short-term energy store, which is connected to the AC voltage circuit or to the DC voltage circuit for the intermediate storage of excess energy. At least one of the electric motors is connected to the AC voltage circuit and at least one is connected to the DC voltage circuit, and the AC voltage circuit is connected to the DC voltage circuit via a rectifier such that an energy exchange is possible between the AC voltage circuit and the DC voltage circuit.

  • Patent number: 5493721
    Abstract: The apparatus includes a mobile receiver for digital audio broadcasting. The transmission process is substantially entirely digital and a whole frequency range is used for the terrestrial transmission. The apparatus includes a receiver for a digital radio signal, particularly wherein the filter coefficient is changeable by a control circuit which generates a first value for the filter coefficient to get the real signal component and thereafter generates a second value for the imaginary signal component, whereby with the switching over of the first and second values for the filter coefficient a simultaneous downsampling of the digital signal is performed.
