    • In a scale with a weighing cell, which can generate weight signals representing the weight of a load each time something is weighed, and with a signal processing system which receives the weight signals and generates: weight data on the basis of the weight signals, information determined on the basis of the weight data such as purchase prices, and/or weighing data containing identification data designating the weighing operation or group of associated weighing operations in question, an elaboration is proposed, according to which the signal processing system has an encryption unit, which can generate encryption data on the basis of at least some of the weighing data, where the signal processing system can transmit a data record containing at least the portion of the weighing data used to generate the encryption data together with the encryption data.

    • A method for the hydrodechlorination of a reaction gas primarily composed of chlorinated hydrocarbons is carried out sequentially. A first step is advantageously carried out in a tubular reactor filled with catalyst and cooled externally, to maintain a temperature within a preferred range of 80.degree. to 230.degree. C. and a radial temperature difference of not more than 40.degree. C. Hydrogen is added to the tubular reactor with a hydrogen excess in a preferred range of 1.1 to 1.5 relative to the reaction gas, based on the stoichiometric consumption. The catalyst is present in a catalyst loading in a preferred range of 0.1 to 1.5 v/vh based on the volume of reaction gas. A fixed bed reactor is advantageously used for a second step, optimally connected in straight transit with the output of the reactor of the first step. The full-space reactor is maintained at a temperature within a preferred range of 200.degree. to 300.degree. C. and a hydrogen excess relative to the stoichiometric consumption is in a preferred range of 2 to 100. Catalyst is present in a preferred amount related to a volume of catalyst in step one according to a ratio in a range of 2:1 to 10:1. The dechlorination is preferably carried out at pressures between 1 and 50 bar. A method is further provided for regenerating deactivated catalysts without accumulation of dioxin in the waste gas, achieved by a reducing treatment, followed by an oxidizing treatment at a temperature at or above the last operating temperature of the catalyst.
    • 依次进行主要由氯代烃组成的反应气体的加氢脱氯的方法。 第一步有利地在填充有催化剂的管式反应器中进行并在外部冷却,以将温度保持在80℃至230℃的优选范围和不超过40℃的径向温度差。加入氢气 基于化学计量消耗,相对于反应气体,相对于反应气体,优选范围为1.1〜1.5的氢过渡到管式反应器。 基于反应气体的体积,催化剂以0.1至1.5v / vh的优选范围存在于催化剂负载中。 固定床反应器有利地用于第二步骤,最佳地连续地与第一步骤的反应器的输出相连。 全空间反应器保持在200℃至300℃的优选范围内的温度,相对于化学计量消耗的氢过量在优选的范围为2至100.催化剂以优选的量存在 根据比例在2:1至10:1的范围内的步骤1中的催化剂体积。 脱氯优选在1至50巴之间的压力下进行。 还提供一种方法,用于再生失活的催化剂,而不会在废气中积聚二恶英,通过还原处理实现,然后在等于或高于催化剂的最后操作温度的温度下进行氧化处理。
