    摘要： The instant invention relates to an improved process for the production of cellular or non-cellular polyurethane urea elastomers, in which diamines which contain ester groups are used as chain lengthening agents. A characteristic feature of the process according to the invention is the use of salts of aromatic diaminocarboxylic or sulphonic acids as a portion of the chain lengthening component. Elastomers produced by this process are distinguished by their improved mechanical properties, in particular their increased tensile strength and tear propagation resistance as well as their reduced permanent elongation.

    摘要： The invention relates to a novel type of electric inductance arrangement for a series of applications in the field of distance measurement, sensor-based detection of objects, and construction of induction machines. The novelty consists in the type of inductance arrangement of the receiver or transmitter coil, said arrangement being designed in the form of a ladder rung arrangement, wherein the ladder spars short-circuit the rungs. The sum of all the short-circuit currents is an indicator of what is occurring in the surroundings of the arrangement. This could be changing magnetic fields caused by transmitter objects or additional ladder-rung systems acting as transmitters. Multiple such sensors and transmitters can be designed in the ladder-rung form, said sensors and transmitters being connected in parallel or in series according to the application under certain circumstances and if necessary assuming the excitation function by moving a conductor through which a direct current is flowing or by applying alternating currents. The aforementioned inductance arrangement results positively in that the coils can all have a completely crossover-free design and are therefore substantially simpler to technically implement for very different applications in electrical engineering. The applicability ranges from short-range distance measuring devices and long-range object location to light detection and efficient induction machines with large or also very small constructions.

    摘要： A belt buckle assembly, especially for a seat belt system in a motor vehicle, includes a belt buckle (10) and a plug-in tongue (12) lockable in the belt buckle (10) by means of a locking mechanism. A component of the locking mechanism of the belt buckle (10) interacting with the plug-in tongue (12) inside the belt buckle (10) and/or the plug-in tongue (12) has/have design features at a locking portion (16) interacting with the locking mechanism of the belt buckle (10) inside the belt buckle (10). The design features enable the plug-in tongue (12) to be locked in the belt buckle (10) only at one of at least two possible orientations of the plug-in tongue (12) in the belt buckle (10).

    摘要： A novel method is employed for collecting optimizer statistics for optimizing database queries by gathering feedback from the query execution engine about the observed cardinality of predicates and constructing and maintaining multidimensional histograms. This makes use of the correlation between data columns without employing an inefficient data scan. The maximum entropy principle is used to approximate the true data distribution by a histogram distribution that is as “simple” as possible while being consistent with the observed predicate cardinalities. Changes in the underlying data are readily adapted to, automatically detecting and eliminating inconsistent feedback information in an efficient manner. The size of the histogram is controlled by retaining only the most “important” feedback.
