From Summary and Conclusions: "The apparatus and experimental methods used to measure relative permeability-saturation relationships by the unsteady-state displacement method are described for gas-oil systems. The unique feature of the apparatus-design of the gas-oil separator-is described in detail."

From Introduction and Summary: "In the assessments of research objectives after World War II it was brought out that little effort had yet been expended on an understanding of turbulent flames.The present report deals exclusively with a second stage of work which was carried out between November 1954 and August 1959. This summary report includes a few new data, but its chief purpose is to reorient the findings toward a better appreciation of what has been accomplished and what most profitably might be done in the near future."
