Abstract: A coil with a distributed winding formed from hairpins that each have two straight-line conductor portions arranged in different slots of a coil body. Contact regions shaped in circumferential direction adjoin the conductor portions at one axial end and are connected at the other axial end through a turning region. The contact regions have at the end remote of the coil body a connection portion that are aligned in radially extending rows. The contact regions of a layer are shaped in the same circumferential direction. A portion of the contact regions of an outer layer is deformed in radial direction to form an additional, and these contact regions are shaped in a circumferential direction opposite to the contact regions of the outer layer.

Abstract: A method for the oxidation of substrates comprising treating an aqueous, basic solution of a substrate having an oxidizable functionality using an elemental halogen as terminal oxidant in the presence of an oxoammonium catalyst/halide co-catalyst system. Use of elemental halogen, preferably chlorine gas or elemental bromine, unexpectedly allows oxidation without significant degradation of the substrate. The substrate is preferably a monosaccharide, oligosaccharide, or polysaccharide, and the oxidizable functionality is preferably an aldehyde, hemiacetal, or a primary alcohol. An effective source of the oxoammonium catalyst is 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO) and a particularly economical and effective catalyst is 4-acetylamino-2,2,6,6-tetramethylpiperidinyl-1-oxy.
