Turbidity coagulant for Columbia River water

Description: In this document, information about the need for a better compound to for filtering process water from the production reactors. It was found that the natural turbidity in the Columbia River was high enough to necessitate the use of a coagulant to minimize the passage of iron through filters. Tests indicated that Ferrisul was the better of the two compounds tested.

Corrosion of Tuballoy-Molybdenum Alloys by Water

Description: The primary purpose of the corrosion work was to find a tuballoy alloy which would be sufficiently corrosion resistant to be useful for canned slugs even if some of the can were to leak. The secondary purpose was to obtain general corrosion data on tuballoy alloys.

Stabilizer for Temperature Control Equipment

Description: From abstract: "A simple electronic circuit is described, the use of which greatly improves the temperature regulations obtainable with Beta equipment. The circuit utilizes the time derivative of the temperature to counteract oscillation and overshoot. No other changes are required in existing equipment for installation of the stabilizer."

Properties of low-aspect-ratio pointed wings at speeds below and above the speed of sound

Description: "Low-aspect-ratio wings having pointed plan forms are treated on the assumption that the flow potentials in planes at right angles to the long axis of the airfoils are similar to the corresponding two-dimensional potentials. For the limiting case of small angles of attack and low aspect ratios the theory brings out the following significant properties: (1) The lift of a slender, pointed airfoil moving in the direction of its long axis depends on the increase in width of the sections in a downst… more

An analysis of life expectancy of airplane wings in normal cruising flight

Description: From Summary: "In order to provide a basis for judging the relative importance of wing failure by fatigue and by single intense gusts, an analysis of wing life for normal cruising flight was made based on data on the frequency of atmospheric gusts. The independent variables considered in the analysis included stress-concentration factor, stress-load relation, wing loading, design and cruising speeds, design gust velocity, and airplane size. Several methods for estimating fatigue life from gust … more
