Abstract: A gripping appliance is disclosed. A head assembly is releasably attached to, and extends distal from, a base member. A plunger actuator moves a plunger along a proximal-distal axis of the gripping appliance. The head assembly includes a carrier with a through opening which receives the plunger and at least two gripping legs. Each of the gripping legs include a tip portion distal of a fixation portion, an actuation portion adjacent to and proximal of the tip portion, and a flex portion between the actuation and fixation portions. The actuation portions contact the plunger when the plunger is in an extended, distal position. The fixation portions are rigidly mounted to the carrier. The actuation and tip portions are distal from the carrier. When no force is transferred from the plunger to the gripping legs, the tip portions converge in a proximal-distal direction of the gripping appliance.

Abstract: A metallurgical furnace cooling plate includes a cooling plate body with front and rear faces and at least one coolant channel inside the body, which communicates with a rear opening on the rear face; and a connection pipe connected to the body so that a pipe channel of the connection pipe communicates with the coolant channel, the connection pipe adapted for carrying coolant fluid to or from the channel. The body includes a receiving bore extending in a bore direction from the rear opening into the coolant channel, the channel being spaced in the bore direction from the rear face by a cover thickness of a cover portion and extends in the bore direction over a width. A connection pipe end portion extends into the receiving bore beyond the cover thickness and is form-fittingly received in the receiving bore along at least a portion of a width of the channel.

Abstract: A cooling assembly for a metallurgical furnace includes a cooling plate disposed inside of a furnace shell of the metallurgical furnace; a cooling pipe traversing a shell opening in the furnace shell and being connected to the cooling plate; and a compensator disposed around the cooling pipe for forming a seal between the cooling pipe and the furnace shell. In order to provide ways for facilitating repair of a cooling system of the metallurgical furnace, the method includes at least the step of performing at least one cutting operation with a cutting device having a fixture and a cutting tool movably connected to the fixture for a guided movement with respect to the fixture. The fixture is mounted to the cooling pipe, whereby the cutting device is aligned with respect to the cooling pipe, and the cutting tool is guidedly moved while performing the cutting operation.

Abstract: Machine elements can be displaced along disjoined path sections by position-controlled machine axes. Movement guidance of the machine elements from the end of a path section to the beginning of a directly following path section along a previously unknown path is provided, wherein location, velocity and acceleration are continuous along the previously unknown path and at the transitions between the path sections and the previously unknown path. Velocity, acceleration and jerk are limited. A preliminary axis guidance and a corresponding required axis time is determined for each of the axes. A greatest required axis time is determined therefrom which is then set as a final axis guidance for this axis. For other axes whose preliminary axis times are smaller than the greatest required axis time, the respective preliminary axis guidance is matched to the greatest required axis time, which is then adopted for the other axes as final axis guidance.
