Abstract: A method and a device are for controlling multiple machining processes in a die-sink erosion machine with several identical or different electrodes (R1, R2, R3, R4), whereby the machining sequence of the machining processes and the electrode used for each machining process are determined by providing the following criteria: a) predefining priorities of workpieces to be machined, of a group of machining procedures, of individual machining jobs (ARB), of work cycles (AZ) and/or work steps (AS) of a machining job; and/or (b) predefining the life span or wear limit of the electrodes used for the individual machining jobs, work cycles or work steps. The overall machining on the die-sink erosion machine is performed with consideration of the determined machining sequence.

Abstract: A method and a device for controlling a number of machining processes on a machine tool with the help of a control device (20) that controls at least one tool for performing said number of machining processes under the direction of a control program, whereby the control program is created using a description of the tools required for performing the machining processes, and whereby the data for describing the tool are hereby divided in memories (24, 25) of the control device (20) into: (a) abstract tool data for describing a standard tool (V1, V2), and (b) specific tool data for correcting and/or adapting the abstract tool data to the actually used tool (R1, R2) or to machine-specific characteristics, whereby the tool description in the control program is obtained by linking the abstract tool data with the specific tool data.

Abstract: A magnetic closure device for items of clothing, leather goods and the like comprising at least one layer of magnetizable powder and at least one layer for covering the layer of magnetizable powder. At least the outer face of the covering layer is free from magnetizable powder.

Abstract: A magnetic closure with a casing made of nonferromagnetic material, for bags, items of clothing and the like, comprising a container which can be coupled to one of two mutually opposite flaps to be joined and forms a seat for at least one ring made of magnetic material. The container is thinner at a coupling surface of the ring. There are also provided elements to increase the tearing resistance of the magnetic ring in the container.

Abstract: A method and an apparatus for controlling a spark erosion process between a workpiece and an electrode for instance a microdrilling electrode, so that the erosion process becomes less susceptible to a malfunction, in that at least one process parameter is measured along a first test interval of the section to be eroded, at least one control value is deduced form the measured values, and this control value is used in a subsequent erosion interval of the section to be eroded. The control value is preferably used for controlling a suitable feed rate of the electrode. The susceptibility to malfunctions is further lessened, in that a differentiation is made between mechanical and other short circuits and in that the electrode movement is controlled differently for mechanical short circuits than for other short circuits.

Abstract: The magnetic button, comprises a male element and a female element which cooperate magnetically with one another, and fixing elements for rearwardly fixing the male and female elements to flaps of fabric. The male element comprises a disk-like body in material sensitive to magnetic attraction and the female element comprises a disk-like body and a magnetic element for attracting the male element. The male element has, on its rear side, a recess tapering towards a hole for the insertion of a tubular end of a fixing element which has, on the opposite side to the tubular end, a collar adapted to retain a flap of fabric, or of other material, arranged on the rear side of the male element. On the bottom of said recess, at the hole, there is a substantially conical protrusion which penetrates into the tubular end pushed into the recess, through the hole, to open out and upturn the tubular end along the walls of the recess to rigidly associate the fixing element and the male element to one another.

Abstract: The magnetic button comprises magnetically cooperating male and female elements each having a rivet element for attachment to a respective flap of an article and at least one holed plate wherethrough the rivet element is passed and clamped between one face of the respective flap and an upsettable end of the rivet. The plate has a substantially crowned shape with peripheral radial cutouts defining peripheral tabs on the plate so as to enable an elastic deformation thereof.
