Abstract: The mechanism comprises a motor and a support leg, and a monitor with a circular movable part on which a like-shaped contact plate is fixed. Inside the monitor are fitted several further contact plates. When the trailer is required to be stationary, the support leg is automatically pushed down by the motor to the ground, and where an uneven ground surface is encountered, the movable part, contact plate it locates against one or the other of the plates inside the monitor. - This causes further contact to be established with the motor which then automatically lowers the support leg further so that the trailer assumes a horizontal position relative to the tractive force. The monitor can be filled with oil so that movements are effected slowly, or even with air or another gas.

Abstract: The tensile straightening device described comprises a braking truss (6), a pulling truss (7) and a truing head (8) situated between the two. Each truss has an inner roller (1 resp. 4) and an outer roller (2 rep. 3) the later-named rollers are rotatably mounted on their own rocker frames (9, 10), which are pivotably mounted in the machine stand. The rollers in both trusses can be pressed towards each other through the tensile force of the belt, increasing the torque transmission capability of the rollers. In order to set the necessary speed differences between the rollers in each truss, these are driven via a differential (108, 124), which also serves as a torque converter. Power transmission capability can thereby also be optimised. The difference in speed between the trusses is controlled by a planetary gear (119). A pinion (135) from a traversing motor (137) works toward an external gear ring (134) on the outer sun gear and is regulated with the selected speed relation from a pulse generator, which is driven by the belt (5) on the pulling truss (7) via a measuring roller. To avoid overloading the truss, the shaft gear (112) on the roller (4) on the outlet side of the truss (7) is connected via its torque rod to a tensile force sensing organ (load cell). If the signal from this indicates that the belt force has a tendency to exceed the permissible limit, the speed of the traversing motor is automatically reduced, thereby reducing belt force.<IMAGE>

Abstract: A method of feeding concrete into a drill hole in the concrete bolting of a rock, in which method a feeding hose is pushed into the hole and concrete is pumped into the hole through the feeding hose at the same time as the hose is drawn outwards within the hole. In order to ensure that the hole is filled properly, the amount of concrete pumped into the feeding hose for the distance the feeding hose is withdrawn, is greater than the concrete amount theoretically sufficient for filling an unbroken hole with concrete when the hose is withdrawn that distance. A device designed for the realization of the method comprises a primary pump which pumps concrete into a piston-type metering pump which in turn pumps the metered amount of concrete into the feeding hose in proportion as the feeding hose is withdrawn.
