    • A substance applying apparatus for applying a substance to an application location. An application element having a wetting body is partially received in an inner tube and the inner tube is received in an outer tube. A fluid connection between the inner space of the inner tube and the inner space of the outer tube is produced by the application of pressure on the substance applying apparatus. The inner tube is comprised of a softer material than the outer tube and at least the bottom of the inner tube is deformable upon the application of pressure on the substance applying apparatus.

    • A sampled analog signal is filtered by a short-term prediction filter. The result, a segmented residual signal, is transformed from a time domain to a frequency domain into several frequency components, each having a frequency-component amplitude. If a number of new amplitudes is calculated by combining the several frequency-component amplitudes, such that the number of new amplitudes is smaller than the several frequency-component amplitudes, a more efficient coder is created. The reduction of the quality of speech coding, due to loss of information, could be decreased if this calculation is based on the so-called Bark scale (critical frequency bands). In a corresponding speech decoder, at the hand of the number of new amplitudes several new frequency-component amplitude are calculated (the number of new amplitudes being smaller than the several new frequency-component amplitudes), which then are inverse transformed from a frequency domain to a time domain into new subsegments. These new subsegments are inverse filtered by an inverse short-term prediction filter to generate a signal which is representative for a sample analog signal.
    • 采样的模拟信号被短期预测滤波器滤波。 结果,分段残差信号从时域到频域变换成几个频率分量,每个频率分量具有频率分量幅度。 如果通过组合多个频率分量幅度来计算多个新幅度,使得新幅度的数量小于几个频率分量幅度,则产生更有效的编码器。 如果这种计算是基于所谓的Bark量表(临界频带),则由于信息丢失而导致的语音编码质量的降低可能会降低。 在对应的语音解码器中,在新的幅度数量的手上,计算出几个新的频率分量幅度(新幅度的数量小于几个新的频率分量幅度),然后从频域逆变换 到时间域到新的子片段。 这些新的子段由反相短期预测滤波器反相滤波,以产生代表采样模拟信号的信号。

    • The invention relates to a process for preparing pyromellitic dianhydride (PMDA) by heterogeneously catalyzed oxidation in the gas phase by means of a gas containing molecular oxygen. The process involves oxidizing benzaldehydes which are 2,4,5-trialkylated by C.sub.1 - to C.sub.3 -alkyl groups or mixtures of benzaldehydes which are 2,4,5-trialkylated by C.sub.1 - to C.sub.3 -alkyl groups and benzenes which are 1,2,4,5-tetraalkylated by C.sub.1 - to C.sub.3 -alkyl groups in the presence of a catalyst. The catalyst contains as active components 5% to 95% by weight of one or more transition-metal oxides of sub-group IV of the Periodic Table of the Elements, from 1% to 50% by weight of one or more transition-metal oxides of sub-group V of the Periodic Table of the Elements. The catalyst also contains from 0% to 10% by weight of one or more oxides of elements of main group I of the Periodic Table of the Elements and/or from 0% to 50% by weight of one or more oxides of elements of main groups III, IV and V of the Periodic Table of the Elements and of elements of sub-groups VI and VII of the Periodic Table of the Elements. The indicated percentages by weight are based in each case on the total weight of the active components and add to 100% by weight.
