The energy revolution has many facets. One of them is the power supply of factories. Here lies the origin of the upheaval in drive technology, which today is already based on direct current, while the grid supplies alternating current. In this book you will learn the advantages of building a comprehensive direct current factory network into which all power generators feed their energy and from which all consumers are supplied directly.All related conceptual, economic, technical and organizational issues are dealt within this book:- Potential and economic assessment of the direct current factory in comparison with a current factory supplied with alternating current- System concept draft for the necessary system and device adjustments with concrete solutions for implementation- Detailed treatment of all relevant technical topics, such as topology, voltage level, supply concepts, grounding and network types, EMC, pre-charging- Characteristic-based control of a direct current network with different supply devices and loads- Guarantee of network stability, even with highly dynamic loads and without additional communication- Treatment of essential security aspects- Planning and design of a direct current network in your own factory, including presentation of the planning tasks and instructions for the userThe book also shows four real applications that were implemented with the manufacturer-independent direct current network described. Different conceptual focal points are explained in each case in order to demonstrate the possible range of use.

Co-rotating twin-screw extruders are extensively used for the preparation, compounding, mixing, and processing of plastics, but also in other industry branches, such as in rubber and food processing, and increasingly in the pharmaceutical industry too. Derived from the classic, bestselling work "Co-Rotating Twin Screw Extruders", this book brings much of the content up to date, with an expanded focus on the fundamentals of co-rotating twin-screw extrusion, including functional zones in the extruder, screw elements, material behavior, flow properties, performance behavior, and application of computational fluid dynamics.Co-rotating twin-screw machines usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Well-founded knowledge of machines, processes, and material behavior is required in order to design and operate twin-screw extruders for economically successful operations. With chapters written by many expert authors from industry and academia, this book provides valuable information on applications from a practical perspective, suitable for both beginners and experienced professional engineers.Also derived from the classic bestselling work "Co-Rotating Twin Screw Extruders", the second book focuses on the application and machine technology of co-rotating twin-screw extrusion. It includes functional zones in the extruder, scale-up and scale-down, machine technology, and many application examples from a broad range of areas.

Automated gripping and handling tasks offer a great rationalization potential but they are still difficult to realize. This book shows you how to ensure process reliability on the basis of combining the right components with advanced application know-how. By explaining basic preconditions of the gripping process and highlighting the milestones of automation history, we guide you all the way through to the center of the handling process - the workpiece. Its ambient conditions and setup are clearly defined as well as the process of setting grippers in motion. Starting with simple linear movements up to multiaxis kinematics, you are provided with the details for practical solutions. A whole range of current applications illustrates the variety and opportunities of automation in daily business.
