A SAW filter has two DMS tracks. Each DMS track includes six converters, with two converters each acting as input or output converters. The two DMS tracks are electrically connected in series by way of four pairs of coupling converters and the associated coupling lines. A common inner ground line is provided between the two DMS tracks, which extends over the entire length of the DMS tracks and crosses the coupling lines. The input converters of the first DMS track are connected to an asymmetrical port, while the output converters of the second DMS track are connected to a symmetrical port.

A band-stop filter is described herein. The band-stop filter includes a piezoelectric substrate and a plurality of surface wave element (SAW) impedance elements on the substrate. The band-stop filter also includes at least one series branch comprising at least one series resonator having a finger period, and a plurality of parallel branches connected electrically in parallel with the series branch, each parallel branch including at least one parallel impedance element comprising an interdigital transducer and having a finger period. The average finger period of the at least one series resonator is greater than the average finger period of the at least one parallel impedance element.

The invention relates to a filter with a first partial filter (TF1), comprising a series resonator (S1) and at least two parallel resonators (P1, P2) that are arranged in respective parallel branches, and with a second partial filter (TF2) configured as a DMS filter. The filter also comprises a housing with a plurality of internal housing contacts (GKi) on a base plate that are connected to terminal areas on the substrate (SU) and external housing contacts (GKa), fewer than the internal contacts, that are connected to the internal housing contacts (GKi) via lines (DL1, DL2) guided within the base plate. At least two lines for connections to ground of the first parallel resonator (P1) and the second partial filter (TF2) are guided separately in or on the base plate and are connected to at least two different external housing contacts (E4, E2).

A surface acoustic wave filter arrangement is described herein. The surface acoustic wave filter arrangement includes a first gate configured to operate symmetrically or asymmetrically, and a second gate configured to operate symmetrically. The filter arrangement also includes a double-mode surface acoustic wave (DMS) filter structure including an input connected to the first gate, and an output. The output includes a terminal pair that includes two symmetrical terminals configured to operate symmetrically. Each of the two symmetrical terminals of the terminal pair is electrically connected at the output of the DMS filter structure to a cascaded resonator.

A component operating with surface-proximal acoustic waves, in particular a filter with novel structure, has interdigital transducers arranged in serial and parallel branches, which are acoustically coupled with one another in different configurations. The component provides a loss-poor filter with simultaneously space-saving arrangement of the filter elements.

A hydraulic clutch has an impeller wheel, a turbine wheel with a turbine wheel shell, and a torsional vibration damper. The turbine wheel is drivable by the impeller wheel. The turbine wheel shell is mounted in an axial and radial sliding bearing so as to be rotatable with respect to a turbine wheel hub. The torsional vibration damper is arranged on the turbine wheel hub so as to be fixed with respect to rotation relative to it. The turbine wheel hub is drivable by the turbine wheel via the turbine wheel shell and the torsional vibration damper. The turbine wheel shell acts on the torsional vibration damper via a connection element. The axial sliding bearing is spatially offset with respect to the radial sliding bearing.

The invention pertains to a heating arrangement for a moving material web, particularly a pre-heater for a corrugated cardboard facility, with a rotating heating roll (3) which can be wrapped around by the material web (13) to be heated at a predetermined looping angle, and with at least two guide mechanisms (7, 11) for the material web which can pivot around the periphery of the heating roll while maintaining their relative positions to each other. The looping angle is determined by means of the position of a first (7) of the at least two guide mechanisms. A second (11) of the at least two guide mechanisms is arranged relative to the first guide mechanism such that in the position of the guide mechanisms defining the maximum looping angle, the material web (13) not directly wrapping around the heating roll (3) is guided at a distance from the heating roll by means of a second guide mechanism (11). According to the invention, a third guide mechanism (9) is provided which, in the direction of the circumference of the heating roll (3) and in a position opposite the position of maximum looping angle, completely lifts the web from the periphery of the heating roll (3) at the position defining the minimum looping angle.
