Abstract: A vehicle operated in a self-propelled program-controlled manner, in particular without a driver, for automatically measuring, marking and/or pre-drilling predetermined desired positions for foundation devices to be introduced into the ground, possibly also for introducing the foundation devices themselves. The vehicle includes a working device, which can be pivoted about pivoting axes and is equipped with a device for automatically detecting and correcting misalignments of the axis thereof and which brings the vehicle to the desired positions with a locating device, which establishes the actual position thereof, and a data processing system, which is loaded with the desired positions in such a way that it can perform the prescribed working steps in a program-controlled manner.

Abstract: A calender wherein the intermediate rolls of a stack of rolls are mounted on pairs of levers pivotable on carriages which are movable up and down in vertical ways provided therefor in the frame. This renders it possible to change the levels of the intermediate rolls without any or without appreciable shifting of the centers of nips of neighboring rolls from a common vertical plane. The carriages are suspended on composite feed screws which can be rotated to move neighboring carriages nearer to or further away from each other.
