Abstract: The invention relates to a method for operating an actuation device (20), which is used to clamp and loosen a clamping device which comprises a tie bolt which can be adjusted in an axial manner in a machine spindle (3), for actuating a clamping head (6) which co-operates with clamping claws (5). Initially, force is exerted upon the tie bolt (4) by means of an actuation device (20) which is used to clamp in an axial clamping direction, until the axial length thereof is fixed in relation to the machine spindle (3) by means of self-locking. According to the invention, after self-locking is obtained, the effect of the force in the direction of clamping of the actuation element (20) on the tie bolt is stopped and remains blocked while the clamping device is being used, and to release clamping, the tie bolt (4) is displaced by the actuation device (20) in the direction of release which is counter to the clamping direction. The invention relates to a device for carrying out said method.

Abstract: A rail mount secures a longitudinally extending rail having a foot to a sleeper of a track system. The mount has a rail base plate on the sleeper underneath the rail foot and unitarily formed with a pair of upwardly projecting holders transversely flanking the rail and each formed with at least one vertically throughgoing bore. Respective anchor bolts engaged vertically downward through the bores have heads bearing downward at least indirectly on the respective holders and are seated in the sleeper to hold the base plate down on the sleeper. Respective elastically deformable clips fitted to the holders below the respective anchor-bolt heads bear upwardly on the holders and downwardly on the rail foot to press the rail downwardly toward the sleeper.

Abstract: A method of leveling metal strip having a thickness ?1 mm has the steps of passing the strip in a travel direction through an upstream braking-roller set and a downstream tension-roller set and through a group of leveling rollers between the braking-roller set and the tension-roller set. A predetermined tension equal to at least 70% of a yield limit of the strip is applied to the strip between the braking-roller set and the tension-roller set for stretch-bend or tension straightening by differentially driving the upstream and downstream roller sets. The strip is bent between the leveling rollers to correct longitudinal curve. Leveling rollers are used of diameters that increase downstream in the travel direction and that are so great that the strip follows the curvature of the leveling rollers at the predetermined tension.

Abstract: Race grooves and lobe outer surfaces of a constant-velocity race gear centered on a gear axis are finished by engaging a first groove of the race gear with a rotating groove-machining tool and relatively moving the race gear and rotating groove-machining tool arcuately to finish the first groove while holding the race gear against rotation about its gear axis. Then the first groove of the race gear is disengaged from the rotating groove-machining tool while holding the race gear against rotation about its gear axis. Then the race gear is rotated about its gear axis to align a second groove with the rotating groove-machining tool while engaging a first lobe outer surface with a rotating surface-machining tool to finish same. These steps are repeated in the same order to finish the second groove and a second lobe outer surface and so on until all the grooves and lobe outer surfaces of the race gear are finished.

Abstract: International-roaming-relevant data are exchanged between two roaming partner networks as part of a new communication relationship. From the start of this communication relationship, a logbook is maintained at least on the data-processing system of the first communication network in which logbook changes are entered that relate to the content of the local database. Based on entries in the logbook, the data-processing system recognizes in completely automatic fashion that a synchronization of data is required and implements this action between the internal network operator database and the data-processing system of the second communication network.

Abstract: An overload protector has an input element, an output element juxtaposed with the input element, and a clamping plate. Fasteners fix the clamping plate to one of the elements against relative movement. A coupling between the clamping plate and the other of the elements permits only limited relative movement of the elements through a stroke having a predetermined length in a predetermined direction. A connector between the clamping plate and the other element fixes the clamping plate and the other element together against relative movement until an overload force greater than a predetermined critical limit is exerted shifting either of the elements toward or away from the other element in the predetermined direction.

Abstract: A semifinished hardenable-steel workpiece is introduced into a gap between a punch tool and a complementary die tool while the workpiece is heated above the AC3 point. Then one of the tools is vertically shifted toward the other tool so as to deform the workpiece to a predetermined shape. Subsequently the workpiece is gripped between the punch and the die tools while cooling at least one of the tools to press-quench the workpiece. Finally, but before the press-quenching is completed, an edge is cut off the still hot workpiece by relatively shifting an upper die and a lower die vertically past each other.
