Tools and Materials in Steel Bottles

Despite the Fact That Sodium Chlorite Emerged Only Recently From the Experimental Laboratory, It Already Has Become an Important Commercial Chemical. With New Speed and Efficiency It is Handling Many Tough Bleaching and Deodorizing Tasks Throughout All Industry

Through Application of Modern Machines and Methods to the Ancient Art of Casting, A Foundry's Atmosphere Can Be Cleared of Dust and Smoke, and Much Back-Breaking Work Eliminated. Only Thus Can a Foundry Hope to Meet Successfully the Ever-Increasing Competition for High-Quality Labor, and the Rapidly Growing Need for More and Better Castings

Applying a Coat of Hard, Wear-Resistant Alloy to a Base of Less Durable Metal Results in Parts That Give High-Alloy Performance Without High-Alloy Costs

By Embedding Entire Electronic Circuits In a New Casting Resin, They Can Be Given Unusually Great Mechanical Stability, And at the Same Time Proofed Against Moisture and Corrosive Fumes of Many Types
