Abstract: An engraving element of an electronic engraving machine for engraving printing cylinders as a shaft oscillating with small rotational angles around the longitudinal axis, a restoring element, a shaft bearing, a damping mechanism, a drive for the shaft, a lever-shaped stylus holder attached to the shaft, and an engraving stylus as a cutting tool. For engraving cups, the engraving stylus executes a stroke motion in the direction of a rotating printing cylinder. The engraving element is arranged with respect to the printing cylinder rotating around the rotational axis such that the shaft of the engraving element proceeds substantially parallel to the rotational axis of the printing cylinder, and the stroke motion of the engraving stylus occurs in a plane oriented perpendicular to the rotational axis of the printing cylinder. As a result, a better geometry of the cups is achieved in the engraving.

A planarly acting hold-down element is provided in a region of a lateral guide roller, the hold-down element pressing the recording medium web onto the deflection seat with a specific pressing power.

Abstract: A zero crossing detector has an analyzer which determines a zero level crossing of a currently input electrical pulse packet and which emits a trigger signal indicative of a determination having been made, and a pre-trigger unit which monitors variations in the amplitude of the current input pulse packet to detect a crossing of a pre-trigger level. The detector further includes a control unit operably connected to the pre-trigger unit which compares the amplitude of the pre-trigger level with any amplitude of a signal derived from the current or a previous input electrical pulse packet, and which automatically controls the amplitude of the pre-trigger level to maintain a working difference therebetween.

Abstract: In a parts handling device and method for handling parts having a central aperture output from a press, the curved slide is provided extending in sloping fashion with its upper end being positioned at the press and its lower end at a location for unloading accumulated parts. A frame is provided for mounting first, second and third clamp assemblies along the curve slide. First, second and third mounting elements are provided beneath the curve surface of the slide in space relationship from one another in alignment with the clamp assemblies. When only two of the clamp assemblies are closed, the tube is rigidly held in its slope position. The control system is provided for selectably opening and closing the first, second and third clamp assemblies in a sequence which permits the parts which are accumulating in front of the first or second clamp assemblies to pass through to the third clamp assembly and eventually to an off-loading station when the third clamp assembly is open.

Abstract: In a dynamic scale, and a method for controlling a dynamic scale, an item to be weighed is transported by a transport device to a weighing cell. The transport device is operable in a number of different operating modes. At the weighing cell, a measured weight value is obtained, and this measured weight value is subsequently interpreted and, based on the interpretation of the measured weight value, the transport device is switched to a different operating mode, which may include reversing the direction of the transport device so as to permit the item to be re-weighed and subsequently discharged from the scale.

Abstract: For level limitation of a time-discrete signal in a digital hearing aid having at least an input transducer, an A/D converter, a signal processing unit and an output transducer, the sampling rate of the time-discrete signal is boosted in the signal path following the A/D conversion and signal values of the time-discrete signal with a boosted sampling rate are limited to a maximum value. Harmonics that arise upon limitation of the signal values that are folded back into the audible frequency range are thus suppressed.

Abstract: In an operating method for a magnetic resonance tomography apparatus a sequence of digital signals is transmitted to the digital-analog converter. An analog signal is emitted from the digital-to-analog converter for each digital signal to a coil system for producing a gradient magnetic field. A signal processor produces a processed digital signal which is supplied to the digital-to-analog converter to produce the analog signal. A difference between the incoming digital signal and the processed digital signal Is determined by the signal processor and is added to the next incoming digital signal or at least for a portion thereof.

Abstract: A pacemaker has a stimulation threshold measuring unit which measures a stimulation threshold voltage value of a heart and a pulse generator for deliverying stimulation pulses of variable amplitudes and durations to the heart. The pulse generator is controlled by a control unit to deliver the stimulation pulses with respective amplitudes related to the measured threshold value and a safety margin. The control unit automatically changes the safety margin in accordance with a predetermined relationship between the safety margin and the measured threshold value, so that the safety margin is progressively increased as the measured threshold value increases.
