    • The invention relates to a process for the production of a nitrogen containing epihalohydrin polymer involving reaction of a nitrogen-containing precursor selected from the group consisting of amines, poly-amines, polyaminoamides, polyurethanes and mixtures thereof with epihalohydrin to form of a solution of said epihalohydrin polymer, the process comprising a purification step to remove organic impurities from the formed solution of the epihalohydrin polymer, said purification step comprising contacting the solution of the epihalohydrin polymer with a fluid under liquid, supercritical or near supercritical conditions to effect extraction of organic impurities from the solution of the epihalohydrin polymer to the fluid, withdrawing fluid enriched in organic impurities from the solution of the epihalohydrin polymer, and separating extracted impurities from the withdrawn fluid, wherein the fluid comprises a substance that at atmospheric pressure and room temperature (about 25° C.) is gaseous. The invention also relates to a process for purifying a solution of a nitrogen containing epihalohydrin polymer.

    • A receiver includes a receiver clock oscillator controllable with regard to its receiver oscillator frequency, means for detecting a number of clock periods that the receiver clock oscillator performs in a specifiable period of time, means for extracting a first and a temporally following second reference entry in a received data stream, wherein means for extracting is implemented in order to control means for detecting on the basis of the extracted first and second reference entry with regard to the specifiable period of time, and means for comparing the number of clock periods of the receiver clock oscillator with the information in the second reference entry in order to control the controllable oscillator depending on a comparison result so that the oscillator frequency is increased or decreased so that the oscillator frequency is in a predetermined ratio to a frequency of the clock oscillator in the transmitter or is equal to the frequency of the clock oscillator in the transmitter. This way, in a simple and secure way, without slow phase-locked loops for a jitter suppression, it is guaranteed that the receiver is fixedly synchronized with the transmitter and that simultaneously in case of a receiver array all receivers are also synchronized among each other.
    • 一个接收机包括一个接收器时钟振荡器,可以相对于其接收机振荡器频率进行控制,用于检测接收机时钟振荡器在可指定的时间段内执行的时钟周期数的装置,用于提取第一和第二时间上的第二参考条目的装置 接收的数据流,其中实现用于提取的装置,以便根据提取的第一和第二参考条目关于可指定的时间段来检测控制装置,以及用于比较接收机的时钟周期数目的装置 具有第二参考条目中的信息的时钟振荡器,以便根据比较结果控制可控振荡器,使得振荡器频率增加或减小,使得振荡器频率与时钟振荡器的频率成比例 发射机或等于发射机中时钟振荡器的频率 。 这样,以简单和安全的方式,没有用于抖动抑制的缓慢的锁相环,可以保证接收机与发射机固定同步,同时在接收机阵列的情况下,所有的接收机也在彼此之间同步 。
