Cutting Oil Comes Back

Plain Water, Water-and-Oil Mixtures, and Straight Oils All Have Helped to Speed Machining Processes and Make Them More Accurate. Every Time Tool Materials Changes Seemed to Point to the Possibility of Eliminating Cutting Oils from the Machine, It Was Found that Better Work Could be Accomplished by Keeping Them on the Job

Gas Turbine PossibiIities

Will Airplanes of Tomorrow be Powered by Reciprocating Engines, by Turbo-Jets, by Turbines Driving Propellers, or by Some Combination ofthese Systems? Analysis of Present Technology Indicates that EachSystem Will Find its Place in Meeting the Varied Requirements of Flight

By Alexander Klemin

Fuels for Jets

Reaction Engines for Aircraft Seem Capable of Operating Efficiently on Simple Fuels. But it May be that this Simplicity is as Yet Due to a Lack of Knowledge of the Means for Obtaining Highest Efficiency from the Power Plants that Will Operate the Aircraft of Tomorrow

Glass and Electronics

Glass Has Played a Vital Role in the Development of Electronics. Now Electronics is Reciprocating by Providing a Flexible Tool for the Glass-Working Industry Whereby Welded Glass Products Can be Produced With High Precision and Sharply Localized Melting Areas

By Keith Henney and vin Zeluff

Glass-Metal Collaboration

From Mirrors to Industrial Pumps, Various Combinations of Metals and Glass Have been Developed to Serve Specific Purposes and to Solve Difficult Problems. The Electrical and Chemical Industries Find Many Uses for Such Partnerships, Retaining the Best Features of Each

By Fred P. Peters and Kenneth Rose

Turbines on Rails

At Operating Speeds, the First Locomotive In America to be Driven by a Steam Turbine Geared Directly to the Driving Wheels Compares Favorably With the Most Economical Reciprocating Units. A New Era of Rail Power May be in the Making as this Locomotive Accumulates Mileage. The Unique Gears are Being Carefully Watched by Engineers

By C. B. Peck

Solarization

Glass in Ultra-Violet Lamps Tends to Deteriorate or Solarize as the Lamps are Used. A New Glass Has Now Been Developed which Transmits Ultra-Violet Radiation Freely but Does Not Solarize. How it Was Determined that Alkali in Glass is the Cause of Solarization
