Abstract: A spinning electrode for production of polymeric nanofibres by electric or electrostatic spinning of a polymer solution or melt includes a conduit for the polymer solution or melt. A spinning surface on the conduit is defined by a face of the conduit or an extension on the conduit. A screw shaft is disposed within an inner space of the conduit, wherein the screw shaft and an inner wall of the conduit form a screw conveyor. The screw shaft has a lower end that projects out from the conduit and is connected to a hub of a magnetic coupling.

Abstract: A system for user interactive visualization of multidimensional space of geometrical shaped partitions. An engine model with operating points may be implemented. A controller may provide tuning for each operating point. Space of the operating points may define a multidimensional matrix, where a number of dimensions is similar to a number of scheduled variables for the engine. Each dimension may be divided into scheduled variable intervals. Multidimensional rectangular partitions may be created from one or more combinations of the intervals. A user may interactively select one or more of the partitions and specify tuning parameters for them. A display may provide graphical feedback about the tuning state or controller behavior about the partitions. The display may also provide a user-selected two-dimensional subspace. The dimensions, i.e., scheduled variables, of the selected subspace and their order may be specified by the user. Additional dimensions of the selected subspace may be presented.

Abstract: A system for winding filamentary material around a cone. The system includes: a drive ring for rotating the cone and a lateral ring for supporting the cone. The lateral ring is rotatable with respect to the drive ring. The angular velocity of the cone is controlled by controlling the rotation of the lateral ring responsive to the tension of the filimentary material and/or responsive to the diameter of the cone.
