  • Patent number: 9733105
    Abstract: A magnetic field measuring device having a semiconductor body with a surface parallel to an x-y plane and having a magnet with a flat main extension surface parallel to the x-y plane, the direction of magnetization changes along the main extension surface due to at least two adjacent magnetic poles, the magnet being rotatable relative to the IC package about an axis of rotation extending in a z direction and the z direction being orthogonal to the x-y plane. An imaginary extension of the axis of rotation passes through the magnet. The semiconductor body has three magnetic field sensors spaced apart from one another on the surface, and each of the magnetic field sensors measures the same component of the magnetic field. All magnetic field sensors are located along the imaginary extension of the axis of rotation within the projection of the main extension surface.

  • Patent number: 9518614
    Abstract: A device used to achieve a releasable connection between two components and at least one shaft on which the components are rotatably mounted. A switching element that is mounted on the shaft can be coupled to one of the components in a non-rotatable fashion by relative motion in the axial direction of the shaft between the components and the switching element. Toothing profiles of the components each comprise at least two spaced-apart teeth rows. A toothing profile of the switching element is provided with at least three spaced-apart rows of teeth, of which at least two teeth rows of the switching element can be brought into a position where they overlap/engage with the two teeth rows of the first component and also where this happens for at least two of the three teeth rows of the switching element with the two teeth rows of the second component.

  • Patent number: 9016453
    Abstract: A connecting device (1) for the rotationally fixed connection of first and second shafts (2, 3) that can rotate relative to one another. The connecting device (1) comprises an axially movable connecting element (5) designed such that, in a first axial position (A), the connecting element (5) forms an interlock between the first and second shafts (2, 3) and, in a second axial position (B), the connecting element (5) releases the interlock. The connecting device (1) also comprises an actuating system (6, 8, 9, 10, 11) for moving the connecting element between the first and second axial positions (A, B) and a stop (16) which limits the axial movement of the connecting element (5) in the first or second axial position (A, B). An impact damper (17) is provided for the stop (16) in order to reduce annoying noise when the connecting element (5) strikes against the stop (16).

  • Publication number: 20150107470
    Abstract: A printing press with at least one gripperless printing unit of a reel-fed printing press, through which a substrate to be printed can be transported in the horizontal direction by a transport device. A dimensionally stable and relatively stiff piece good, which during the transport and printing does not adapt to cylinder contours of the printing units, can be transported through the or each gripperless printing unit by the transport device. The printing press further includes a feeder, which keeps the piece good to be printed ready and via which the piece good to be printed can be circumference register-precisely and page register-precisely placed on the transport device for the subsequent printing in the printing units.

  • Publication number: 20140208967
    Abstract: A method for controlling at least one control parameter from a number of parameters of an inking unit of a printing press is disclosed. Based on at least the control parameter, a value of an ink density on a substrate to be printed by the printing press is calculated by an inking unit model and the calculated value is used as input quantity for controlling instead of an actual value. Here, the calculated value is exclusively calculated based on a number of parameters of the inking unit at least at times.
