Automatic Operation is Attained With the Cathode-Ray Tube. By Blacking-Out Parts of the Tube's Screen, Light Shows Only When Defective Parts Pass on the Production Line. A Photocell Watches the Screen and Activates a Reject Mechanism When it Sees Light, Giving Highly Accurate Results

Inaudible Wave Power is Being Used Today to Detect Flaws and Deviations in Manufactured Products, to Measure Underwater Depths and Distances, and to Detect Underwater Objects such as Fish. Principles have Been Developed Which Bave Interesting Possibilities for Future Expasion

Military Developments Hold Definite Promise for Peace-Time Applications in Both Commercial and Private Flight. Radar Principles can Give Birth 10 Systems that Will Warn of Possible . Collisions Provide Block-Signal Control and in Olher Ways Promote Safety in the Air

Man's Insatiable Curiosity About the Possible Wealth of Materials Hidden in the Ground has Led Him to Employ Many Weird Contrivances in His Search. As Science Advances, the Witch-Hazel Divining Rod Used for Locating Water Has Given Way to Electronic Techniques for Subsurface Probing

Electronic Control Methods have Increased Reliabilily and Speed in Welding. Bringing Precision Operations to the Assembly Line. Factors Governing Quality of Welds Can be Held Automatically Within Predetermined Limits. Magnesium Now Welded Electrically

Through The Use of Such Electronic Processing Agents as Radio-Wave Components, Supersonic Waves, X-Rays, Ultra-Violet Rays, and Infra-Red Rays, New Methods of Producing Desired Physical and Chemical Changes in Materials Have Been and Are Being Developed by Industry

Because of the Versatility of the Electron Tube--and of the Electron-- Physical and Chemical as Well as Electrical Quantities Can Be Measured. And When Quantities Can Be Measured, the Variations Detected by Electronics Can Be Translated into Accurate Control Processes

Photocells and Tubes, Taking Up Where the Human Eye Fails, Make Possible Accurate Matching and Measuring of Colors, Leading to Applications in Many Fields. In Colorimetry Standard Colors are Eliminated and a New Scientific Tool is Provided that Promises Much for the Future

Printed Designs Moving Through a Paper-Handling Machine at High Speeds Are Invisible to the Eye, but the Phototube in a Modern Control System Sees these Designs and Makes Each Arrive at a Particular Point at a Particular Inslant. Other Industrial Uses

By Means of Electron Tubes, Direct Current Motors Can be Operated From Alternating Current Power Lines. The Advantages are Variable Speed Over a Wide Range, Constant Torque at Slow Speeds, Constant Horsepower at High Speeds. Many Industrial Applications Listed

A Demonstration of Popping Corn Without Heat Has Led to the Development of Electronic Methods of Heating Many Materials --Metallic and Non-Metallic -- by Means of High Frequency Currents. Present Applications are Relatively High in Cost, Yet Bring Many Industrial Advantages
