Photograph of Port Arthur, Texas, with an aerial view of the courthouse, bridge, Pleasure Island, and YMCA. The courthouse stands in the stone building in the center of the photo, surrounded by streets that are lined with cars. The bridge is raised for a passing boat. Beyond the bridge, a roller coaster can be seen. The Watkins Studio mark is in the bottom right corner.

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 the uranium. This historical document describes these early studies in the following sections: exceptional characteristics of the slug program; extrusion; drawing, waging and rolling; outgassing and straightening; Project 1030 (procurement of an additional sixty tons of finished slugs over and above that quantity originally supplied to the Clinton Laboratories) Machining, grinding and grooving; development of canning methods; production of canned slugs; and The Dummy Slug program.

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 face throughout the greater part of the cycle. The piston moved laterally in the cylinder under the influence of piston side thrust."

"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 pressure ratio exists" (p. 123).
