Abstract: The invention relates to a structural unit and to a method and a tool system for producing such a structural unit for an electric machine, such as a rotor or in particular a stator, with a lamination stack (1) composed of a plurality of metal laminae layered on top of one another in the direction of a longitudinal axis, which lamination stack is, in the circumferential direction, assembled from multiple stack segments (10) with lamina segments which are arranged in the circumferential direction and interlock by means of lateral holding structures.

Abstract: A process is disclosed for operating an industrial plant by means of a guidance system that controls processes in the industrial plant, in which process operation-relevant data such as states, malfunctions and/or degradation of devices of the industrial plant are acquired by an operator; the operation-relevant data are acquired in an operation monitoring system and stored in electronic, preferably standardized form, and operation-relevant data on events which can affect process control, such as malfunctions of devices, are electronically transmitted to the guidance system.

Abstract: The present invention concerns methods and compositions that involve whey protein isolates. Methods of the invention include purification processes for preparing whey proteins that are substantially nondenatured across a range of pH, including their isoelectric points. As such, they have low turbidity in solution across a wide range of pH values. Whey protein isolates can be integrated into compositions and solutions that have nutritional, pharmaceutical, and other applications.
