300 Area, January 22--January 28

Description: Progress is reported on the topics of extrusion and canning. The information on canning is broken down into: Production test 313-74-M, studies of aluminium cans, selection of surface rejection standards, thorium, and the effect of high and low tin in bronze on tin carry-over to canning bath.

Columbia River Temperature Survey at Hanford Engineer Works: Preliminary Report

Description: It was agreed during a meeting on July 10, 1945 that an investigation should be made by the Technical Department to determine how fast and in what fashion the temperature of the effluent water from the 100 Areas is dissipated in the columbia River. A preliminary report on this investigation is submitted herewith for review by interested parties.

A Study of the Distribution of Impurities in the Extraction of Uranyl Nitrate with Ether from Aqueous Solutions

Description: Early in 1942 it had been found on a laboratory scale that certain impurities such as the Rare Earths were removed by small water washes from an ether solution of Uranyl Nitrate. It was hoped that in the large production units to be constructed that the water soluble impurities would all be washed out by the time the radioactive Thorium had been removed, so that the decrease in radioactivity could be used as an index of the amount of all kinds of impurity remaining in the ether layer.

The Distribution of Precious Metals in Various Residues Obtained in the Preparation of Uranyl Nitrate From Pitchblende

Description: A study was made of the distribution of Ag, Au, Bt, and Pd in the residues from an extraction process in which purified UO/sub 2/(NO/sub 3/)/sub 2/ is prepared from a pitchblende ore. The residues studied were the gangue Pb cake, the BaSO/sub 4/ cake, the filtrate boildown cake, the raffinate cake, and the purified UO/sub 2/(NO/sub 3/)/sub 2/. Samples representing three different batches of ore were used. The following conclusions were reached: (1) neither Ag nor Pd are present in the ore in si… more

The Detection of Small Amounts of Fluorine in Large Amounts of Chlorine

Description: Abstract: "Tests have been developed for both the qualitative detection and quantitative determination of fluorine in chlorine. The qualitative test is made by passing the gas through manganous chloride. If the pink solid tubes brown there is greater than 0.5 percent of fluorine in the gas. The quantitative test is a modification of the Steiger and Marvin Test with oxidized titanium solution."

A Thermodynamic Study of the Turbojet Engine

Description: "Charts are presented for computing thrust, fuel consumption, and other performance values of a turbojet engine for any given set of operating conditions and component efficiencies. The effects of pressure losses in the inlet duct and the combustion chamber, of variation in physical properties of the gas as it passes through the system, of reheating of the gas due to turbine losses, and of change in mass flow by the addition of fuel are included. The principle performance chart shows the effect… more

Quantitative Treatment of the Creep of Metals by Dislocation and Rate-Process Theories

Description: "An equation for the steady-state rate of creep has been derived by applying the theory of dislocations to the creep of pure metals. The form of this equation is in agreement with empirical equations describing creep rates. The theory was also used to predict the dependence of steady-state rate of creep on physical constants of the material and good agreement was obtained with data in the literature for pure annealed metals" (p. 169).
