Title: Hydraulic lifting device
Inventor: DANTLGRABER JOERG
IPC: B66F7/20
Filed: 1997-03-07
Abstract: The hydraulic lifting device has two lifting cylinders in series, one of which is a differential cylinder, to which hydraulic fluid is fed via a valve (26) from a pump (28) driven by an electric motor (60). The hydraulic medium is displaced from the differential cylinder (21) and fed to the second cylinder drives the second cylinder in synchronism. For lowering, the direction of rotation of the electric motor is reversed and the pump is driven in the reverse direction by the fluid flowing out of the differential cylinder via the valve depending on the load, whereby the pump drives the electric motor which acts as a generator.

IPC: H04J3/06
Filed: 1998-07-18
Abstract: Netzelemente (NE1, NE2) eines synchronen digitalen Nachrichtenübertragungsnetzes werden auf den Referenztakt eines primären Referenztaktgenerators synchronisiert. Um die Ausfallsicherheit des Netzes zu erhöhen, werden zwei primäre Referenztaktgeneratoren (PRC1, PRC2) verwendet. Im fehlerfreien Betrieb wird das erste Referenztaktsignal an die Netzelemente übertragen und zur Synchronisierung verwendet und das zweite Referenztaktsignal steht als Ersatzreferenztaktsignal zur Verfügung. Im Fehlerfall wird die Synchronisierung auf das zweite Referenztaktsignal umgeschaltet. DOLLAR A Das erfindungsgemäße Synchronisierungsverfahren sieht vor, daß zumindest eines der zwei Referenztaktsignale zur Unterscheidung der beiden Referenztaktsignale durch eine vorbestimmte Bitfolge im Kopfbereich von mit dem Referenztaktsignal erzeugten Nachrichtensignalen (STM-N) oder durch Beaufschlagen des Referenztaktsignals mit einer Phasenmodulation markiert wird. Dadurch ist gewährleistet, daß das Netz von einer einzigen Referenztaktquelle synchronisiert wird.
