Abstract: A process and device for measuring and processing in real time the changes of level between two or more points in buildings, structures, machinery or the like, when interested by works of civil engineering, wherein a laser ray generated by a laser tube and rotated on a planar or conical surface hits one or more targets constituted by fixed or mobile photodetectors, said targets being placed in correspondence with said points. The signals generated by the targets are transferred to a computer to be processed and immediately read (FIG. 1).

Abstract: An anchorage structure and method for positioning cables in an excavated hole, comprises a plurality of cables adapted to be subjected to a tensioning load having common ends arranged in the hole and disposed in substantially a common plane. A plate having a plurality of bores therethrough through which the ends of the cables extend is secured to the cables so that the plate is positioned substantially parallel to the plane of the common ends of the cables. A resinous mass encases the plate and the cables in an area above and on all sides of the cables, adjacent the ends thereof, leaving a remaining space in the hole around the mass and above and below the mass and concrete filled into the hole in the remaining space. Each of the cables has a coating for insulating them from the concrete and permitting an individual sliding movement of the cables.
