Abstract: A gripper device in a sheet-processing machine includes a gripper, a gripper pad associated with the gripper and a first drive for moving the gripper out of an opened position thereof into a closed position thereof. The gripper is cooperatively engageable with the gripper pad for producing a clamping force for holding sheets being processed. A second drive is separately operable from the first drive during a production printing operation of the sheet-processing machine. The first and second drives are operable for positioning the gripper and/or the gripper pad so that clamping faces of one of the gripper and/or the gripper pad are movable by the second drive perpendicularly to clamping faces of the other of the gripper and/or the gripper pad.

Abstract: A corrosion-protected tension member of steel composed of a plurality of individual wires twisted into a strand, wherein each of the individual wires of the strand is composed of a steel wire freed from deposits by a surface treatment and surrounded by a continuous sheathing of a corrosion-resistant sheet metal, wherein the sheathing is rigidly connected to the core wire by at least one common cold deforming process with intermediate annealing of the sheathing. The tension member of steel is used primarily as a reinforcement element or a tension member with wedge-type anchoring systems at its ends.

Abstract: The present invention relates to biocide batches based on cross-linked native oils, which are used to provide thermoplastic molding compositions with protection against insects and bacterial and fungal attack.

Abstract: In a method for operating a refrigerating unit including an expeller, condenser, evaporator and absorber, with a solvent circulation, a working substance circulation and a by-gas circulation, the working substance ammonia is expelled from a rich ammonia solution with continuous supply of thermal energy and subsequently is liquefied by heat absorption, is evaporated with absorption of heat from a cooling chamber and is absorbed from the weak ammonia solution, regulation of the thermal energy required for expulsion being effected in dependance on temperature changes with relation to a given temperature of the cooling chamber with the aid of an electronical module using fuzzy logic rules.

Abstract: Lubricant base materials containing ester groups may be stabilised by adding a small quantity of carbodiimides and the service life of lubricants manufactured therefrom may be decisively extended.

Abstract: The object of the invention is a corrosion-resistant composite wire with diameters <10 mm, which has a concentric, homogeneous high-grade steel coating, wherein this coating, depending on the diameter of the wire and the application, can vary 15-30% by volume, and its strength can vary, depending on the core wire used and the degree of forming, up to .ltoreq.2000 N/mm.sup.2. To produce such a composite wire, for example, a high-strength, patented and surface-pretreated steel wire is sheathed with a strip of high-grade steel. In the first forming step, the longitudinally welded high-grade steel sheath is pressed tightly onto the core wire and in subsequent drawing steps, the composite wire is drawn to the final dimensions. At least between two forming steps, there is a selective annealing treatment of the composite wire by means of a rotary arc, whereby only the high-grade steel layer is heated to the annealing temperature.

Abstract: The invention concerns a process and a device for surface heat treatment of rod-shaped, longitudinally extended materials with metal surfaces by means of an arc, which rotates and is magnetically driven around the axis of the billet, wherein the arc moves between an annular electrode (anode) and the billet serving as cathode that runs through it.According to the invention, the problem of developing improved measures for stabilizing an arc, inter alia, is solved by rotating the arc by a direct current magnet arranged behind the annular electrode in the direction in which the billet runs and at the same time the magnetic field induced by the direct current magnetic counteracts the pulling effect on the arc base point by the moved billet and the annular electrode current is divided into two divided currents.The field of application is primarily surface heat-treating of rod-shaped, longitudinally extended materials with metal surfaces.
