Abstract: A device for the precise determination of the position of a moving railroad vehicle on a track in a transloader measurement stretch has a multiplicity of switch elements arrayed along one of the rails and actuators positioned to be engaged either by the felly portion of the wheel or the flange portion of the wheel regardless of where the wheel and the track are and in all positions of the wheel on the rail in its sinusoidal movement back and forth as the wheel travels along the rail.

Abstract: A scanning device for a machine for the automatic sharpening of broaching or reaming tools has a horizontal slide for receiving a tool to be sharpened and a vertical slide having at least one grinding spindle. A scanning finger which can be moved approximately vertically relative to the scanning device is provided for ascertaining the position of a particular tooth and is coupled with at least one member which emits displacement-dependent signals for triggering drive mechanisms for the machine slides. In order to enable a substantially arbitrary, yet precise, guidance of the scanning finger in order to ascertain dimensions which are of importance for the geometry of the tool, the scanning finger is attached on one of two slides which are displaceable at right angles relative to one another and a displacement pickup is associated with each slide for detecting the displacement distance from a position of rest traveled by respective slide.

Abstract: A scanning finger for a scanning device of a machine for automatically shening tools has a horizontal slide for receiving a tool to be ground and a vertical slide carrying at least one grinding spindle. The scanning finger has a scanning face, which is substantially horizontal and limited by and undercut to rest on the free face of a tool tooth to be ground, as well as a face which is downwardly offset from the scanning face and is intended for ascertaining the cutting face of the tooth. In order to make it possible to scan the cutting face at a distance from the original cutting edge, the face for ascertaining the cutting face of the tooth is undercut in the direction of movement of the horizontal slide and below the horizontal scanning face, and below the undercut it has a measuring edge to rest on the cutting face.
