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： 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： 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.
