    • This invention describes a monitoring device which monitors the safety of a printing machine. The printing machine has a drive, a control unit arranged upstream of the drive, command buttons which are connected to the control unit and via which the start-up of the printing machine can be initiated, as well as sound generators, connected to the control unit, for the emission of an acoustic alarm signal after the actuation of one of the command buttons initiating the start-up. The monitoring device ensures that a start-up of the printing machine is only carried out if an acoustic alarm signal has previously been properly emitted. This is achieved, according to the invention, by the monitoring device registering the emission of the acoustic alarm signal and, in the event of the alarm signal not being emitted, inhibits the drive of the printing machine from starting up. The monitoring device inhibits the drive via the control unit, disabling the main contactor connected to the drive, applying the brake or switching off the field current via a field contactor.
    • 本发明描述了监视打印机的安全性的监视装置。 印刷机具有驱动器,布置在驱动器上游的控制单元,连接到控制单元的指令按钮,可以启动打印机启动的命令按钮以及连接到控制器的声音发生器 单元,用于在致动启动启动之一的命令按钮之后发出声学警报信号。 监视装置确保仅在先前已经正确发出声学警报信号的情况下才执行打印机的启动。 根据本发明,通过监视装置登记声警报信号的发射,并且在不发出警报信号的情况下,禁止打印机的驱动而启动。 监控装置通过控制单元禁止驱动,禁用与驱动器连接的主接触器,施加制动或通过现场接触器关闭励磁电流。

    • A process for preparing porous carbon support materials comprises treating activated carbon or coke, having a particle size of about 5 to about 50 .mu.m, a specific surface area of about 10 to 1,000 m.sup.2 /g, a hardness of at least about 95% attrition resistance, with solvent or solvents, and then heat treating the activated carbon or coke at a temperature of about 2,400-3,000.degree. C. under an inert, gas atmosphere; said solvent or solvents affecting the mineral and organic impurities in the activated carbon or coke such that after said subsequent heat treatment, substantially all of said impurities are removed. A hard, mechanically stable, porous carbon support material consisting essentially of highly purified activated carbon, highly purified coke or a mixture thereof, said support material having a carbon content of at least 99%, a specific surface area of about 1 to about 5 m.sup.2 /g and a particle size of about 5 to about 50 .mu.m, may be prepared in this way.
    • 制备多孔碳载体材料的方法包括处理具有约5至约50μm的粒度,约10至1,000m 2 / g的比表面积,至少约95%的磨耗的活性炭或焦炭 电阻,用溶剂或溶剂,然后在惰性气体气氛下在约2,400-3,000℃的温度下热处理活性炭或焦炭; 所述溶剂或溶剂影响活性炭或焦炭中的矿物和有机杂质,使得在所述随后的热处理之后,基本上所有的所述杂质都被除去。 基本上由高度纯化的活性炭,高度纯化的焦炭或其混合物组成的坚硬,机械稳定的多孔碳载体材料,所述载体材料具有至少99%的碳含量,约1至约5m 2的比表面积 / g,粒径约5〜约50μm可以这样制备。
