Patent DE-19854567-A1 (DE)
Inventor: BACHMANN OLE
IPC: H02M7/219
Filed: 1998-11-26
Abstract: The invention relates to a method for controlling a rectifier circuit and to a corresponding rectifier circuit. Said rectifier circuit has a rectifier (2) in series with an inductor (4), a diode (5) and a load (6). A capacitor (7) is arranged parallel to the load (6) and a controlled switch (8) is arranged parallel to the series connection of the diode (5) and load (6). Said switch is connected to a control device (9) which produces a control signal using the voltage (U3) through the load. The aim of the invention is to improved the efficiency. The control device (9) has a phase displacement device (12) which effects a phase displacement of the alternating component of the voltage (U3) through the load in the order of magnitude of 270 degrees. This allows the direct voltage signal that is used for obtaining a control signal for the switch (8) to be superposed by an alternating voltage signal whose frequency corresponds to the frequency of the ripple at the output of the rectifier (2) and which has a phase difference in relation to the ripple that is less than a predetermined measure.

Patent DE-19905461-A1 (DE)
Inventor: GESSNER NORBERT
IPC: B65G43/02
Filed: 1999-02-10
Abstract: The invention relates to a measuring device and a method for continually determining the tensile forces of the chains in the chain conveyor belt of a scraper chain conveyor in the coal face area in coal mining. Known devices for determining the chain strain of a chain strand which is used in mining and which is moved in the conveyor are based on sensors being mounted on a chain link. When the chain link is stretched, a measuring signal is generated which is proportional to the stretching effect. Said signal is fed to a moveable receiving device that accompanies the measuring point and can be used as a storage unit, whereby the signal is fed via measuring lines. Said signal is received and processed. Information on the strains is thus provided with tremendous delay and involving high costs. The aim of the invention is to provide a method and measuring devices which enable to continuously determine the tensile forces of the chains in the chain conveyor belt of an operating scraper chain conveyor in order to almost simultaneously determine the strain ratio of the chain conveyor belt in relation to the permissible strain. According to the inventive method and said measuring devices, the deformation of the cribs of the chain links in relation to one another is determined as a change in distance in relation to zero strain, whereby said deformation is caused in a chain link and under strain. Said deformation is transformed into an electrical measuring signal that can be transmitted wirelessly and is transmitted to an output device for simultaneously outputting the strain.

Patent DE-19916277-A1 (DE)
Inventor: SZOT KRISTOF
IPC: B25J7/00
Filed: 1999-04-12
Abstract: The invention relates to a device for moving an object (5), comprising at least two piezoelectric displacement elements (1, 2, 3) which can be separately electrically controlled and present an active connection (4) between them which is such that the resulting changes in the length of the piezoelectric displacement elements can add up to a total length which in turn is such that the maximum possible length of the displacement in a given dimension is greater than the maximum possible change in length of an individual piezoelectric displacement element. The piezoelectric displacement elements work in a telescope-like manner. This makes it possible to avoid the disadvantageous use of long piezoelectric crystals for executing relatively large movements. The telescope-like cooperation of the elements further allows for a highly compact structure.
