The metal fabrication program for the Clinton Engineer Works and the Hanford Engineer Works. Including the Dummy Slug Program and the Unbonded Slug Program -- Project 1553

Description: The uranium slugs were used as the charge into the pile for the manufacture of minute quantities of plutonium. So little was known of uranium`s commercially adaptable physical properties that it was relegated almost to the category of a laboratory curiosity. A series of experimental and developmental programs were inaugurated to determine not only the extrudability, machinability and other physical properties, but also the influence on these of microscopic quantities of impurities present in th… more

A visual photographic study of cylinder lubrication

Description: From Summary: "A V-type engine provided with a glass cylinder was used to study visually the lubrication characteristics of an aircraft-type piston. Photographs and data were obtained with the engine motored at engine speeds up to 1000 r.p.m. and constant cylinder-head pressures of 0 and 50 pounds per square inch. A study was made of the orientation of the piston under various operating conditions, which indicated that the piston was inclined with the crown nearest the major-thrust cylinder fac… more

Some Effects of Compressibility on the Flow Through Fans and Turbines

Description: "The laws of conservation of mass, momentum, and energy are applied to the compressible flow through a two-dimensional cascade of airfoils. A fundamental relation between the ultimate upstream and downstream flow angles, the inlet Mach number, and the pressure ratio across the cascade is derived. Comparison with the corresponding relation for incompressible flow shows large differences. The fundamental relation reveals two ranges of flow angles and inlet Mach numbers, for which no ideal pressur… more

A study of the Quartz Fiber Balance No. 1 (Information Report)

Description: This article is a de-classified document produced by Monsanto Chemical Company-Unit III in Dayton, Ohio. The date of the document is August 1, 1945, and the subject is the operation of a quartz fiber microbalance. In particular, the document examines whether temperature fluctuations affect the operation of the instrument. Data was presented to show that the accuracy of the instrument was indeed affected by ambient temperature.
