Air Compressor

An air compressor, also known as an air pump, is a machine that decreases the volume and increases the pressure of a quantity of air by mechanical means. Air thus compressed pos sesses great potential energy because when the external pressure is removed, the air expands rapidly . The controlled expansive force of compressed air is used in many ways and provides the motive force for air motors and tools, including pneumatic hammers, air drills, sandblasting machines, and paint sprayers.

At Microsoft Press, we use tools to illustrate our books for software developers and IT professionals. Tools very simply and powerfully symbolize human inventiveness. Theyre a metaphor for people extending their capabilities, precision, and reach. From simple cal ipers and pliers to digital micrometers and lasers, these stylized illustrations give each book a visual identity, and a personality to the series. With tools and knowledge, theres no limit to creativity and innovation. Our tagline says it all: the tools you need to put tech nology to work.

The manuscript for this book was prepared and galleyed using Microsoft Word. Pages were composed by Microsoft Press using Adobe FrameMaker+SGML for Windows, with text in Garamond and display type in Helvetica Condensed. Composed pages were delivered to the printer as electronic prepress files.

Acknowledgments

As always, many people have been involved in the development of a book such as this.

Many thanks go to the team at Microsoft Press, who have done such a good job of steering this project through the writing and editing process. As commissioning editor, Danielle Bird Voeller was brave enough to believe Julians assertions that this would be a worthwhile project. Kathleen Atkins provided excellent guidance and support as editor, and made the writing process as smooth as it could be. Thanks must also go to the other reviewers and edi tors involved in the project, especially Marc Young and Brian Johnson, who provided valuable technical support. Any errors which may remain in the book are, of course, our responsibility and not theirs.

Finally, wed like to thank our respective families for putting up with the disruption involved in producing a book like this.
