Abstract: A 3D printing apparatus and method prints a partial part, and continues to print the part after the partially-printed part has been rotated. Each partial printing operation may include reinforcement via application of one or more layers of continuous fiber. The rotation and continued printing of the partially-printed part allows for fiber orientation in different orientations for the printed part.

Abstract: Capturing MR image data of an examination object using an MR apparatus, including: performing a balanced steady-state free precession sequence with phase progress of 180 degrees per repetition time using the MR apparatus; in the balanced steady-state free precession sequence, providing a white-marker gradient in order at least partially to balance a dephasing caused by a magnetic-field-changing object in the examination object; capturing image data of the examination object using the MR apparatus at an echo time; and adjusting a phase development between phase magnetization of a first and second materials, which form an interface in the examination object, in the balanced steady-state free precession sequence using the MR apparatus, wherein due to the adjusting of the phase development before an effect of the white-marker gradient, a co-phasal alignment of a magnetization of the first material and of the second material at the interface is effected at the echo time.

Abstract: A tool storage system stores tool holders for use in machine tools. The tool holders hold tools such as milling cutters, taps, drills, reamers, chamfering or deburring tools or the like. The tool holders may have standard taper-shanks. A receptacle is provided for each tool holder. The receptacles are arranged on a generally vertical array and hold the tool holders generally horizontally. The tool holders may be retained by engagement of a pull stud in the receptacle. The generally vertical array arrangement permits storing a large number of tools in a small footprint. In embodiments, a computer system provides functions for managing the tools and/or jobs in which the tools are used.

Abstract: The invention relates to a gear for conveyors which has a drive shaft to which a drive motor is to be fastened as well as an output shaft with which the gear is connected to the conveyor. However, at least one gear step is provided within the gear. Moreover, the gear is provided with a freewheel locking in one direction of rotation. A second gear step is provided in this case between the freewheel and the elements transmitting torque between drive and output shaft during normal operation, so that the freewheel should be operated at a higher speed and must only provide a low holding moment in the event of a stoppage.

Abstract: A coupling is described for conducting electrical signals between two members which are movably mounted to each other. The coupling uses a piece of compressed electrically conductive elastomer material to maintain physical and electrical contact between the two members. The coupling is well adapted for conveying low current analog or digital control signals. In a preferred form the coupling is a rotary coupling which has a drum mounted for rotation in a cavity in a housing. The outer surface of the drum and the inner surface of the cavity each have a number of circumferential electrically conductive rings aligned in pairs. A ring of electrically conductive elastomer material is compressed between each pair of rings. The coupling can be advantageously combined with a rotary coupling for hydraulic fluid. In the combined electric-hydraulic rotary coupling the electric portion of the coupling is flushed with hydraulic fluid.
