Abstract: A CNC machine, or CNC machining centre, for the automated and computer-controlled production or machining of components. The CNC machine does not have any operator module attached to it, or any operator module connected to it, that remains permanently connected to the CNC machine during the operation of the CNC machine.

Abstract: In a process for insertion of wire (30) in the form of a field coil (56) between the pole horns (38, 40) and the stator wall (36) of a double-pole stator (14) of an electric motor, the stator (14) consists of two stator halves (12a, b) and the wire (30) to form the coil (56) is inserted by way of a winding arm (16) rotating about a rotation axis (y) lying perpendicular to the stator axis (x), where during the winding process, for temporary formation of an enlarged insert groove (34, 35) for the wire (30), a winding accessory (32) is laid against the outer edge of the stator (14) and the free ends of the pole horns (38, 40) are covered with a wire guide sleeve (42). The process allows the winding of stators in which the pole horns largely cover the rotor external diameter of collector motors, leading to a higher motor power.

Abstract: A gradient coil system for a nuclear magnetic resonance tomography apparatus has a set of saddle coils disposed on a first cylindrical surface for generating the x-gradient, and a set of saddle coils disposed on a second, separate cylindrical surface for generating the y-gradient. The saddle coils in each set include three sub-coils having predetermined ampere turns, and formed by cable conductor wound exclusively by convex turns arranged in the same cylindrical surface. A middle coil of the three sub-coils has an arced portion facing the z=0 plane in an x-y-z coordinate system which approximates an arc of an ellipse.

Abstract: A magnetic device is arranged in a curved section of the path of electrically charged particles of an acceleration installation around a beam guiding chamber. The magnetic device contains curved coil windings built up of superconducting rectangular conductors, which have convex outsides, concave insides as well as transition regions at the coil ends between these sides. The superconducting coil windings (4a) according to the invention are arranged at least with their winding parts (57, 58) forming the convex outsides (53) and concave insides (54) in grooves of correspondingly formed coil formers of the magnetic device, with the grooves extending downward at least approximately perpendicular to the plane (x-y plane) determined by the particle path. In addition, the superconducting coil windings (4a') in the region of their coil ends (55') are bent up saddle-shaped.

Abstract: A method and apparatus for fabricating a curved disc-shaped magnet coil, especially for particle accelerators. The conductor is wound around a coil form which has a convex outside and a concave inside with therefore a partly negative curvature, using elements pressing the conductor onto the inside of the coil form or the conductor turns already in place. The conductor is fixed in its position after the winding process. In order to wind the magnet coil quasi continuously, the conductor is applied to the coil form or the conductor turns already present under tension in the region of the convex outside and, in the region of the concave inside, pressure elements are provided which are guided along on the inside and wind the conductor under relatively reduced tension. The pressure elements are spaced from each other at least largely regularly, exert a predetermined radial pressure, and are held there until the conductor is fixed in position.

Abstract: A method for manufacturing a disc-shaped curved magnet coil, particularly for a system for accelerating and/or storing electrically charged particles such as electrons. The conductors of the coil to be made are to be arranged around a winding core having a convex outside and a concave inside and are then to be fixed in position around the winding core. A coil form or fitting piece of predetermined shape is first added to a winding core, so that a provisional winding body with only positive radii of curvature on its outsides is formed. The conductors are wound under tension around the winding body and subsequently are fastened only to the winding core of the winding body and, after the coil form is removed, the thus exposed conductor portions facing the region of the concave inside of the winding core are pressed against this inside and fixed in position.
