  • Patent number: 10821414
    Abstract: A housing having a heatable housing jacket, which surrounds a treatment chamber and forms a rotationally symmetrical treatment surface extending in the axial direction, and a drivable rotor, arranged in the treatment chamber and extending coaxially, for producing a material film on the treatment surface. The rotor comprises a hollow shaft, arranged in a manner distributed over the circumference of which are spreading elements. The hollow shaft surrounds a condensation space, in which a condenser is arranged. At least some of the spreading elements are configured as transport elements, which impart a transporting component to the material in the direction from the material inlet to the material outlet. Some of the spreading elements are configured as transport elements and some as distributing elements, which project from the hollow shaft and which comprise teeth, the shearing edge of which encloses an angle of less than 45° relative to the axial direction.

  • Patent number: 9110145
    Abstract: A controller of a magnetic resonance system determines an activation signal vector based on a target field predetermined for the controller in conjunction with field characteristics of field coils known to the controller. The activation signal vector includes a respective activation signal for each field coil. The controller determines the activation signal vector such that within a predetermined examination volume of the magnetic resonance system, any deviation of an ideal field that would result if ideal coils were subjected to the activation signals of the activation signal vector from the target field is minimized. The controller determines a compensation signal vector based on the activation signal vector in conjunction with eddy current characteristics of the field coils known to the controller. The compensation signal vector is used to minimize a deviation of an actual field from the target field within the predetermined examination volume of the magnetic resonance system.

  • Patent number: 8991036
    Abstract: A method for producing a gradient coil assembly for a magnetic resonance imaging system includes applying a number of primary gradient coils and a number of secondary gradient coils to a winding mandrel to form the gradient coil assembly. A control coil arrangement is associated with the winding mandrel. During an intermediate check before completion of the gradient coil assembly, at least one coupling inductance value between the control coil arrangement and at least one of the primary gradient coils and/or at least one of the secondary gradient coils is determined. An arrangement of the relevant gradient coils on the winding mandrel is corrected as a function of the at least one coupling inductance value.
