Abstract: A radio transponder and method for data transfer between a radio transponder reading device and the radio transponder, wherein a control unit of the radio transponder controls a change in a load impedance via a control signal having a selected switching pulse frequency and a selected switching pulse quantity to produce a response signal, where the control unit codes multiple-valued at least ternary symbols into the control signal, and where symbol values are assigned to respective switching pulse sequences each having a unique combination of switching pulse frequency, switching pulse number and phase shift such that only combinations for which the quotient of switching pulse number and switching pulse frequency lies within a predefined value range are selected.

Abstract: The invention relates to a method and a device for milking milk residues to achieve the extraction of as much of the milk as possible that is preset in the udder. According to the method, a rubber teat element (10) in a teat cup (1) is displaced in a milking motion by a negative suction pressure caused by adjustable pulse phases consisting of alternating suction and pause phases and of a pulse intensity, in order to a volumetric flow of milk. The volumetric flow is continuously recorded and if it decreases, the motion of the rubber teat element is modified in a targeted manner.

Abstract: An inking unit for a rotary printing machine includes an ink fountain, a pivotable ink fountain holder in which the ink fountain is mounted, an ink ductor, and a pivotable ink ductor holder in which the ink ductor is mounted. The ink ductor holder and the ink fountain holder are connected by an operating cylinder so that ductor and the ink fountain can be pivoted jointly to a first position in which ink flows out of the ductor without flowing out of the fountain, and so that the ductor can be pivoted away from the first position to a second position while the ink fountain remains in the first position, thereby creating a gap between the ductor and the ink fountain.

Abstract: A cassette for a wedge-shaped ink well of a printing machine has a bottom and a rear wall and two side walls. A front of the cassette, opposite the rear wall, faces a duct roller of the printing machine when the cassette is inserted into the ink well and is open. A handle connected to the upper portions of the side walls is positioned such that the cassette tends to incline to prevent ink from flowing out of the front of the cassette when the cassette is handled outside of the printing machine. The bottom and the sides of the cassette are sealed against the ink well adjacent to the duct roller. A seating arrests movement of the cassette relative to the ink well when the cassette is inserted in the ink well thus ensuring that the duct roller uniformly inked between sides of the ink well.

Abstract: An inking apparatus for rotary printing machines includes a rotatably mounted, drivable ink roller and at least one ink container mounted such that it can be swivelled away from the roller, favoring cleaning and ink change. The swivelably mounted ink container permits the ink container to be emptied in an operator-friendly fashion avoiding ink residues to the greatest possible extent and also permits thorough cleaning of the ink container and the roller with good accessibility. The roller is mounted in a separate holder and the holder is mounted in the frame in such a way as to be swivelable separately from as well as together with the ink container.
