Abstract: Methods are provided for magnetic resonance (MR) image reconstruction. In one exemplary method, a low-resolution prescan MR data record is recorded, the prescan MR data record is adjusted to a provided form of a higher resolution scan MR data record which is likewise to be recorded, a compressed prescan MR data record is generated by geometric coil compression, the scan MR data record is recorded, a compressed scan MR data record is generated by geometric coil compression, and the compressed scan MR data record is then corrected by the compressed prescan MR data record. An MR system includes an MR coil arrangement configured to generate static and high-frequency magnetic fields at the site of an object to be examined and to detect response signals output by the object, and a data processing device configured to process data of the object generated from the response signals, wherein the data processing device is embodied to carry out the method.

Abstract: A ring-spinning machine has a longitudinally extending row of spindles rotatable about parallel spaced axes on a frame, and a drive that has an endless flat belt tangentially engaging all of the spindles. A pair of deflector rollers between two of the spindles are rotatable about respective axes parallel to the respective spindle axes and spaced longitudinally apart along the belt. A drive wheel is rotatable about an axis parallel to and spaced transversely from the roller and spindle axes and the belt passes around one of the deflector rollers, around the drive wheel, and around the other of the deflector rollers. A motor rotates the drive wheel about the wheel axis.

Abstract: A stiff mounting unit is formed by a pair of longitudinal main girders and support bars for a two sided spinning or twisting machine frame. Bridge pieces are connected to these bars and girders. The support rollers and pressing rollers of the drafting or feed units are mounted on the bars.
