| Efficiently Controlled |
|  In the Swiss canton of Wallis, the Dutch company DSM Nutritional Products AG has introduced a new concept for saving energy, in which large cooling circuits are equipped with frequency-controlled drives. The new solution not only allows more dynamic control of the plant in comparison with the previous valve control but also offers savings due to the much lower consumption of primary energy.

| The Future on the Test Bench |
|  In the immediate neighborhood of the Opel headquarters in Ruesselsheim - in Mainz-Kastel - Opel and GM engineers from GM FCA (General Motors Fuel Cell Activities) have been developing emission-free fuel cell drives since 1998. The ambitious goal: To develop a competitive fuel cell propulsion system by 2010 which is comparable in performance, durability and costs with today's combustion engine powertrains in large quantities. The powertrain modules for the fuel cell automobile from General Motors are being tested on two Siemens test benches since 2004.

| Seam Sealing Safe and Sound |
|  DaimlerChrysler AG has developed a new kind of fully automatic application process for body seam sealing in a pilot project. Potential innovations for the company-wide automation standard integraMCG are to be validated and ensured simultaneously for the control-technical implementation of the process.

| TIA in packing machines |
|  Packing machines need to be highly productive and flexible. Distributed, programmable drives enable retooling of machines for different variations of packagings in the shortest possible time. A clear, easy to operate human-machine interface is an absolute must for the plant operator here. The SIG Pack Systems AG in Beringen, Switzerland, relies on the multi-functional platform Simatic MP 370 with 12-inch touch screen for their packing machines.

| Converters and inverters - an A to Z |
| Siemens Automation & Drives offers a range of variable speed drives to satisfy the varied requirements of modern industrial applications. The spectrum extends from cost-effective, multifunctional inverters for small power ratings, to reliable large drives in the megawatt range, right through to highly dynamic drive systems for tooling and production machines.

| Heavy-duty precision drives for plastics extrusion |
| Unlike machines designed for the production of well-specified products, lab equipment is frequently exposed to particularly high loads, whereby it must also satisfy stringent requirements in terms of accuracy and repeatability. Offering high performance, as well as 32-bit microprocessor technology, the Micromaster 440 low-voltage inverter represents the perfect solution for the new single and twin-screw extruders from Noris Plastic GmbH &. Co. KG.

| A change of scenery made easy |
|  Innovative printing units with freely combinable rotogravure and screen printing are Herbert Olbrich GmbH & Co. KGs answer to the demand for highly flexible printing machines for rollware. Other trailblazing innovations are electronic single drives in the scope of a homogeneous automation concept from one provider. "Changes of scenery" can be made much faster, more flexibly and with lower travel losses.
