Abstract: The present invention concerns a motor for generating torques around more than one axis with respect to an object that can be rotated and revolved around only one point. Only one mechanism is necessary to maintain a prescribed position or to produce changes in position around one or more axes (X, Y, or Z).The permanent-magnet excited synchronous machine comprises stator shells (10 & 10.1), multiple-phase windings (11 & 11.1), and a rotor (12) with permanent magnets (13 & 13.1), whereby the annular and spherical surfaces (14) of the rotor are more extensive than the annular and spherical surfaces (15) of the shells.All the spherical surfaces share the same center (M) of curvature, which simultaneously constitutes the origin of the coordinate systems, and the center of rotation. The shaft (17) is supported only at the center of curvature and such as to ensure freedom of motion throughout the reference coordinate system (21).

Abstract: The invention concerns a bridging system comprising several uniform bridge section in the form of track supports (1). The width of the bridge can be continuously adjusted with telescoping pipes ( 2 ). The stationary ramps ( 3 ) on the track support are slotted like a comb and, once the have been assembled and connected to the pivoted-out lower truss system (4), can accommodate any compression forces and bending moments that occur when traveled. Since each track support is the same shape, the bridging system has a smoothly curving upper roadway edge.The traction component (5) in each track support travels back and forth between pivoting stays (9) provided with connectors (8) and the overall lower truss system can be pivoted into the track support.This bridging system, which consists of modular track supports (1), is outstanding for its compact traveling state and few connectors and can be positioned by appropriate transporting and laying equipment.

Abstract: An arrangement for laying a bridge, in which a vehicle carries a plurality of track support sections of a bridge to be laid. The vehicle has a laying device which includes a laying support with cantilevering rails traveling on rollers. Telescoping stays are located at ends of the laying support, and a left-side track-laying device and a right-side track-laying device are mounted on telescoping shafts. The telescoping shafts are displaced hydraulically across the longitudinal axis of the vehicle. Each of the track-laying device on the laying support has provision for placing the track support sections. A piston-and-cylinder is located on arms mounted at ends of a horizontal one of the shafts, whereas piston-and-cylinder is mounted on ends of a rear one of the shafts.
