This Manual is intended primarily for use by foundry personnel aboard repair ships and tenders. The recommended practices are based on procedures proved workable under Navy conditions and are supplemented by information from industrial sources. The Manual is divided into two general sections. The first section, chapters 1 through 13, contains information of a general nature, such as "How Metals Solidify," "Designing a Casting," "Sands for Molds and Cores," "Gates, Risers, and Chills," and "Description and Operation of Melting Furnaces." Subjects covered in these chapters are generally applicable to all of the metals that may be cast aboard ship. The second section, chapters 14 through 21, contains information on specific types of alloys, such as "Copper-Base Alloys," "Aluminum-Base Alloys," "Cast Iron," and "Steel." Specific melting practices, suggestions for sand mixes, molding practices, gating, and risering are covered in these chapters. This manual has been written with the "how-to-do-it" idea as the principal aim. Discussions as to the "why" of certain procedures have been kept to a minimum. This manual contains information that should result in the production of consistently better castings by repair ship personnel.

[A] treasure trove of practical wisdom."—James Howard Kunstler, author of The Geography of Nowhere Matthew Stein’s comprehensive primer on sustainable living skills—from food and water to shelter and energy to first-aid and crisis-management skills—prepares you to embark on the path toward sustainability. But unlike any other book, Stein not only shows you how to live green in seemingly stable times, but to live in the face of potential disasters, lasting days or years, coming in the form of social upheaval, economic meltdown, or environmental catastrophe. When Technology Fails covers the gamut. Inside, you’ll learn: The basics of installing a renewable energy system for your home or business How to find and sterilize water in the face of utility failure How to keep warm if you’ve been left temporarily homeless Practical information for dealing with water-quality issues Alternative health and first-aid techniques Each chapter describes skills for self-reliance in good times and bad. Chapters Include: A survey of the risks to the status quo Supplies and preparation for short- and long-term emergencies Emergency measures for survival Prepping water, food, shelter, and clothing First aid, low-tech medicine, and healing Securing energy, heat, and power Metalworking Utensils and storage Low-tech chemistry engineering, machines, and materials Fully revised and expanded, When Technology Fails ends on a positive, proactive note with a chapter on “Making the Shift to Sustainability,” which offers practical suggestions for changing our world on personal, community and global levels.
