摘要： The invention concerns a corrugation-free rail for track-bound vehicles. In the invention, the rail comprises a metallic material in the area of the travel and/or guide surfaces of which the stress limit or yield point is above the wheel-induced compression. Preferably, the rail in the area of the travel and/or guide surfaces is composed of a non-work-hardenable material.The preferred material composition is (by weight):______________________________________ carbon 0.2 to 0.4% chromium 13 to 18% molybdenum 0.3 to 1.5% manganese 0.5 to 1.5% silicon 0.3 to 1% remainder is iron. ______________________________________

摘要： A method for grinding the running and/or guide surfaces of rails or the like, where the running surfaces are ground by an endless revolving abrasive belt which can be moved against the running surfaces, wherein the abrasive belt revolves transversely to the longitudinal axis of the rail and embraces, at least partially with prestress, the running and/or guide surfaces. An apparatus for performing the method includes a mobile grinding machine, which an endless abrasive belt, guided at least on one rail of the track, which abrasive belt revolves over a drive roller and a reversal arranged at a distance therefrom and which can be moved by these against the surfaces of the rail to be ground. The reversal is formed of two reversing rollers which have a comparatively small spacing from each other, that the axes of the reversing rollers and of the drive roller 19 being arranged to be parallel to the longitudinal axis of the rail. Thus, the abrasive belt revolves transversely to the longitudinal axis of the rail and at least one reversing roller can be lowered beneath the upper edge of the running surface of the rail for partially embracing the surfaces of the rail.
摘要翻译：一种用于研磨轨道等的行进和/或引导表面的方法，其中运行表面通过能够抵靠运行表面移动的环形旋转磨料砂研磨，其中研磨带横向于纵向轴线旋转轨道和至少部分地具有预应力，运行和/或引导表面。一种用于执行该方法的装置包括移动研磨机，该移动研磨机将至少在轨道的一个导轨上引导的环形研磨带，该研磨带在驱动辊上旋转，并且反转布置在距离其一定距离处并且可以通过这些对着待磨削轨道的表面。反转由具有彼此相对较小间隔的两个反转辊形成，反转辊和驱动辊19的轴线布置成平行于轨道的纵向轴线。因此，研磨带横向于轨道的纵向轴线旋转，并且至少一个反转辊可以在轨道的行进表面的上边缘的下方降低以部分地包围轨道的表面。

摘要： In a digital telecommunications system having common 64 kbit/s communications channels in which an additional 8 kbit/s signal channel lying outside of the respective 64 kbit/s common channel is available for outslot signaling only on partial segments of a connection line, for example, only on a subscriber extension circuit, the outslot signaling being carried out on the other connection segments in a subchannel of the 64 kbit/s common channel.
