Abstract: A marking device for the identification of an object includes laterally offset regions formed directly on the object with different magnetic characteristics. The different regions can have histeresis loops shifted differently to one another.

Abstract: A piezoelectric valve whose housing defines a valve chamber wherein at least one piezoelectric flexural transducer is located. The piezoelectric flexural transducer possesses a contact face, which faces a first outer wall of the valve housing. This first outer wall is in the form of a wiring support which possesses a support body consisting of plastic material, which at the outer side opposite to the valve chamber bears a wiring arrangement. The wiring arrangement is in electrical contact by way of a via extending through a cutout in the support body with the piezoelectric flexural transducer, since the via consists of an electrically conductive elastic plug, against which the at least one contact face is thrust at the inner face of the support body.

Abstract: The inventive marking device (1) for applying to objects has a magnetic coding with areas of different magnetisation. According to the invention, the coding has at least one magnetic base layer (3) and at least one magnetic coding layer (5) and these are configured in such a way as to produce areas with non-parallel or antiparallel magnetic coupling over the length of the base layer (3) or coding layer (5).

Abstract: The invention relates to a method for producing a marking device (1), according to which a coding coating is applied to the surface of a support (2). The coding coating comprises at least one magnetic base layer (3), at least one magnetic coding layer (5) and a non-magnetic intermediate layer (4) placed therebetween. Said intermediate layer is composed in such a way that areas of non-parallel or anti-parallel magnetic coupling occur. The invention is characterized in that zones on the surface of the support (2) are roughened, before the coding coating is applied. The invention also relates to apparatus for carrying out said method.

Abstract: The invention relates to a marking device (1, 11) for the identification of objects with a coding of regions (4, 5, 13) with different magnetic properties. The marking device is characterized in that magnetic regions (4, 5, 13) are so magnetically biased that their hysteresis loops (7, 8, 15) are shifted on the field strength axis (H) relative to the magnetization axis (M).

Abstract: The invention relates to a marking device (21) for the identification of objects, comprising a coding consisting of areas (24, 25) of differing magnetic properties. The marking device is characterised in that it has magnetic areas (24, 25) consisting of a homogeneous, ferromagnetic or ferrimagnetic material, each of said areas having a magnetic anisotropy with an easy and hard magnetic axis, whereby areas with a different orientation of the easy magnetic axis and/or areas with remanence of different strengths succeed each other in at least one specific direction. The invention also relates to a method for producing a marking device of this type and to apparatus for carrying out the method.

Abstract: Determining a measurement value in particular a distance in the area of a printing device, especially a printing machine, with a measurement instrument arranged on a device component and oriented relative to a measurement or reference area to improve the measurement value determination even when the printing device is operating. An oscillation or vibration of the measurement instrument is recorded and taken into account in the measurement.

Abstract: A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece.
