    摘要: The invention relates to a transducer operating with surface waves that shows an improved frequency response of the group delay vs. the SAW-transducer familiar until now with its high flank steepness of the transfer function. The transducer is constructed on the basis of SPUDT-cells, whereby in constructing the transducer at least two cells are anticipated which are identically constructed up to their scaling. They are thereby differently scaled in longitudinal direction. According to the degree of scaling, the local phase of the acoustic wave lets itself be influenced so that the waviness in the frequency description of the group delay in the pass band of the filter, in which the transducer according to the invention is used, amounts to at most 50 ns.

    摘要: The invention relates to a tensioner (1) for a traction drive with a rotationally fixed housing (2) to a side of which a rotatable swivel arm (10), provided with a rotatable tension roller, is associated. A torsion spring (7) is placed between the housing (2) and the swivel arm (10) for loading the swivel arm (10) in the direction of an end position. Support of the tension spring (7) is realized by an insert (17a) placed in a circular ring shaped space (16) radially defined by a housing portion and the torsion spring (7).

    摘要: A reactor vessel includes a dipleg connecting a tubular syngas collection chamber and a quench chamber. The collection chamber connects to the dipleg via a slag tap having a frusto-conical part starting from the lower end of the collection chamber and diverging to an opening connected to an interior of the dipleg. The slag tap has a first tubular part connected to the opening of the frusto-conical part and extending in the direction of the dipleg. A second tubular part connects to the frusto-conical part or to the tubular part and extends toward the dipleg. The second tubular part is spaced away from the dipleg to provide an annular space having a discharge conduit. The discharge conduit has a discharge opening located to direct water along the inner wall of the dipleg. At least half of the vertical length of the first tubular part extends below the discharge opening.

    摘要: In connection with generating a global model of output variables of a nonlinear dynamic real system, for example, of an internal combustion engine, a drive train, or a subsystem thereof that covers the entire space of all operating points of the system, a measurement of the system is performed for a subset of variation points that are defined by a set of parameters of the system.In order to provide rapid and precise generation of the experimental designs, and the global optimization thereof, while taking into account the test constraints and additional criteria, at least two subsets selected as a function of each other are determined in succession, a common experimental design is generated taking into account the variation points of all subsets, and the system is measured based on this experimental design.

    摘要: A surface acoustic wave (SAW) filter includes a transducer having an acoustic track to pass a SAW. A center frequency of the filter excites the SAW. The acoustic track includes cells along a longitudinal direction of the acoustic track. Each cell has electrode fingers. The cells include different cell types, where a cell type is defined by a connection sequence of electrode fingers of a cell. At least some of the cells are functional cells, each for exciting and/or reflecting the SAW. There are at least two functional cells, each of which includes at least one wide electrode finger and at least one narrow electrode finger. A reflective strength of a target functional cell is configurable by changing a width of an electrode finger in the target functional cell but by maintaining an overall width of the target functional cell substantially constant.
