Rates of fuel discharge as affected by the design of fuel-injection systems for internal-combustion engines
Using the method of weighing fuel collected in a receiver during a definite interval of the injection period, rates of discharge were determined, and the effects noted, when various changes were made in a fuel-injection system. The injection system consisted primarily of a by-pass controlled fuel pump and an automatic injection valve. The variables of the system studied were the pump speed, pump-throttle setting, discharge-orifice diameter, injection-valve opening and closing pressures, and injection-tube length and diameter.

Metallurgical Laboratory, Chemical Research - Radiation Chemistry, Report for the Month Ending May 15, 1943
Technical report that information has bee obtained on the effect of beta and gamma radiation on the electrical resistance of insulating materials The results are summarized. The recovery to original resistance values has been measured. In general, the initial rate is rapid for the first few hours; the rate then decreases sharply. Certain samples show evidence of complete recovery. Effects on mechanical properties of several plastics has also been studied. Data on gas evolution from several organic materials including those suggested by the physiological shield have been extended to include both beta and deuteron bombardments. Samples of "Press-wood" are being evaluated. The effect of current on the H2O2 production in water containing I- has been studied at several I- concentrations. Water contain-dissolved CO2 shows the presence of oxidant (presumably H2O2). H2O2 has been produced by recoil protons from the scattering of fast neutrons in de-oxygenated water. Radioactive solutions do not greatly affect the applicability the glass electrode providing the electrode is thoroughly washed with distilled water before immersion in the standard buffer solution.

Analysis of Heavy Water by Equilibration
Technical report discussing that the deuterium concentration of heavy water can be determined by equilibrating the water with deuterium gas in the presence of a catalyst with subsequent analysis of the equilibrated gas on the mas spectrometer. The apparatus for equilibration analyses maybe be considered in three parts: 1) apparatus for introducing the ingredients into the reaction chambers; 2) the reaction chambers; 3) the mass spectrometer for analysis of the equilibrated gas. The isotopic composition of the deuterium gas to be used as the starting material is primarily governed by what gases are available. In general it is best to use gas within about one percent on either side of the final equilibrium composition. No reaction takes place between deuterium gas and water molecules in the absence of a catalyst. Platinum oxide is used as the catalyst.

Interim report No. 2 on Production Test No. 105-17-P, Laboratory evaluation of proposed lubricants
The lubricant (Calel A-60) used to reduce pushing forces when discharging slugs from pile tubes forms a cloudy emulsion with water. During the initial period of operation at 100 B and D areas, spillage of lubricant during discharge produced so much cloudiness in the basin water that it interfered with sorting operations. An investigation was started to see if a lubricant could be found that would effectively lubricate tubes during discharge and which would form optically clear systems when mixed with water. This report presents the data on a number of lubricants which were suggested for test.

Altitude-performance and Reynolds number investigation of centrifugal-flow-compressor turbojet engine
From Introduction: "Altitude-chamber and wind-tunnel investigations of the performance of turbojet engines such as those reported in references 1 to 4 have shown that the conventional correction factors fail to generalize the engine performance variables at high altitudes. An investigation was therefore made at the NACA Lewis laboratory to determine the altitude performance of the J33-A-23 turbojet engine and to demonstrate the magnitude of departure of actual altitude performance from that predicted from sea-level performance."

Investigational Drilling, Hoskinnini Mesa
From to the files: To date, all the mineralization seen in the Monument Valley area in the Shinarump formation has been in scour channels. The mineralized rock occurs at or near the bottom of the channel. On Hoskinnini Mesa, all the channels examined to date contain some mineralized material. Channels observed may in some cases contain copper without apparent uranium mineralization; others definitely exhibit copper-uranium mineralization.

Final report on Process Test MR-105-3, Evaluation of larger crossheader screen openings for B, D, and F reactors
The installation of crossheader pressure gauges on the reactors has shown that excessive pressure drops occur across some crossheader screen assemblies, and that the pressure drop across the four inch assemblies in the B, D, and F Reactors is significantly greater than the six inch assemblies at the DR and H Reactors. Since the inlet water system pressure is limited to the 4.5 psi discharge pressure of the secondary pumps, the reduction of pressure resistance downstream of that point would result in higher reactor flow rates and increased boiling limits. This test described in this report was initiated to determine if four inch crossheader screens having equal and 50% greater free-area than DR -- H screens would significantly reduce the crossheader screen pressure drops at the B, D, and F Reactors, and to obtain information regarding cone screen plugging rates with larger size screen openings.

Identification of Reaction Products Formed During Magnesium Reduction of Uranium Tetrafluoride: Report
Abstract: "This report describes the results of X-ray diffraction examination of reaction products from a series of experiments performed by Mallinckrodt Chemical Works as an acid in understanding the process of bomb reduction of UF4. UF4 is initially reduced to UF3 by magnesium at 560 C., and subsequently to metal at 600 C. MgF2 from the initial reaction forms a coating on the magnesium which retards the final spontaneous reaction."

The Identification of the Angular Inclusions Present in Rolled Uranium
Hanford uranium contains minute angular inclusions which affect the microstructure, reactivity, and other important factors controlling the serviceability of the metal. Small quantities of the inclusions have been isolated by chemical means, and the x-ray diffraction patterns and chemical analyses of the isolated materials have been determined. As a first step in the identification of the inclusions present in rolled uranium, a search was made for a chemical method of separating the inclusions from the matrix metal.

A preliminary report concerning the development of an underground water supply, RDS-14. A review of reference material and previous work including recommendations for this program
The geology of the Hanford-White Bluffs area was studied preliminary to drilling well(s) and developing an underground water supply. A study of the geology of the Hanford-White Bluffs area has shown that it consists of terrace deposits of sand and gravel covering a consolidated sandstone known as the Ringold formation. Beneath the Ringold are successive layers of basalt interbedded with volcanic ash, sand and other materials. In the past the Columbia River has cut channels through the area which extended downward into the Ringold formation. The old channels have been filled and upgraded to the present land surface in repeated flooding of the river over a long period of time. An aquifer used needed to be capable of supplying more than 34 million gallons of water per day.
