  • Patent number: 6588093
    Abstract: In a manufacturing method and apparatus for manufacturing sheet metal packets in punch-packeting technology with a round or oval iron cross section. laminations are punched from a ribbon and are provided with depressions at one side and with elevations at the other side that coincide with the depressions and lie opposite them, with the elevations being in the form of at least two circular nipples being pressed into the depressions upon assembly of each packet. In one lamination per packet, serving as a separating lamination, cylindrical holes are punched instead of the depressions, the nipples of the neighboring lamination engaging into these holes. Laminations are thereby punched from the strip that respectively exhibit different outside contours, particularly different widths, and are joined with one another to form a packet that has a cross-section that is at least partially round, by virtue of the sheet metal packet having graduated edges.

  • Patent number: 6313746
    Abstract: The magnetic marker strip is formed of a signal strip made from ferromagnetic material with a low coercive force onto which there is applied ferromagnetic material whose coercive force is distinctly higher than that of the material of the signal strip. The signal strip is relatively long as compared with its width, and emits harmonic-containing signals in a first, unmagnetized state as a consequence of the magnetic field in the interrogation region and emits no harmonic-containing signal in a second state in this magnetic field. The ferromagnetic material with the larger coercive force is arranged in the form of a plurality of control elements at a spacing from one another on the signal strip, the width of the control elements being essentially equal to the width of the signal strip, and the control elements switching the signal strip into the first state when they are in a first, unmagnetized state, and switching the signal strip into the second state when they are in a second, magnetized state.

  • Patent number: 6171694
    Abstract: A label for use in a magnetoelastic electronic article surveillance system has a strip of an amorphous alloy, forming a resonator having a resonant frequency, when activated by a magnetically semi-hard strip. The strip of amorphous alloy is fixed at one side to the magnetically semi-hard strip, and has a length of ¼ wavelength of the resonant frequency.

  • Patent number: 6171408
    Abstract: In a method for strip-wound core strips composed of amorphous ferromagnetic material, an amorphous ferromagnetic strip composed of a cobalt-based alloy which contains additives of iron and/or manganese in a proportion of between 1 and 10% by atomic weight of the alloy is cast from a melt by means of rapid solidification. The amorphous ferromagnetic strip is then subjected to a magnetic field transversely with respect to the strip direction as it passes through heat treatment. Once the strip-wound core strips have been cut to length from the heat-treated, amorphous ferromagnetic strip, strip-wound cores, preferably toroidal strip-wound cores, are wound. These strip-wound cores can be used to produce inductive components which have excellent magnetic characteristics, and, in particular, inductive components can be produced whose toroidal strip-wound cores have a mean diameter of d≦10 mm.

  • Patent number: 5817191
    Abstract: An iron-based, cobalt-containing soft magnetic alloy suitable for use as a core in a magnetic switch or other exciting circuits has a cobalt content of 6 through 30 weight percent, at least one of the elements chromium, molybdenum, vanadium and tungsten in range of 3 through 8 weight percent, and a remainder iron, possibly including inconsequential contaminants. The alloy has a coercive field strength of lower than or equal to 3.2 A/cm, and a saturation flux density of greater than 1.9 Tesla.

  • Patent number: 5703559
    Abstract: For the production of a plate packet for magnet cores that have an opening in the longitudinal direction of the plate lamellae, inner plate lamellae with reduced cross-section are stacked in the region of the opening. Of these inner lamellae, at least two lie in one plate plane and together have a surface that is reduced in size by the cross-section of the opening in comparison to the size of the outer plate lamellae.
