Review of Drilling Methods and Procedures With Results Obtained
"In this review and critique of many matters, most of them related to a central scheme, namely the outlining of methods and procedures in the Commission, ore-finding technique, new empirical criteria as guides to analyses of grade, ore realization factors, and many other subjects that have a bearing on our field methods used have been treated."

Investigations of Ion Exchange Methods for Recovery of Uranium From Liquors Produced by Acid Leaching of Gunnar Ore
An ion exchange testing program was completed on Gunnar acid leach liquors and pulps. A standard column system and a resin-in-pulp system, both using anion exchange resins, were investigated. The Gunnar leach liquors are readily amenable to the recovery of uranium by ion exchange.

Additional Extraction and Ion Exchange Studies of Temple Mountain District Ores
Uranium extraction of 95% has been obtained from samples of Temple Mountain ore by a cyclic test procedure in which the new feed was not roasted. This procedure involved acid leaching the ore, flotation and roasting of the carbonaceous material, and acid leaching the roaster calcine.

The Development of Fixed Screen Resin-In-Pulp Devices
A resin-in-pulp process was developed using a series of fixed-screen or Winchester cells. Various laboratory and pilot plant models were constructed and tested under simulated plant conditions. The fixed-screen device proved very effective in the recovery of uranium and/or vanadium by a continuous, resin-in-pulp process.

Second Report on Liquid Metal Level Instrument
The liquid metal level instrument will operate at tank temperatures up to 1000 F. Overall system accuracy depends on operating conditions, as described in the report. Test accuracies from 2 to 8% have been obtained from full to empty tank. The primary detector unit successfully passed navy HI shock test.

Path of Triple Point for spherical Shocks Above a Rigid Plane
Paths of trip points of Mach reflections produced by 0.5-oz pentolite detonations have been observed for various burst heights. The slopes, Y, at points on the curved path are found to vary from values of Y predicted from plane shock wave data. This discrepancy is attributed to the shock strength conditions at the early inception of the Mach reflection, which later influence the triple point equilibrium, and in lesser degree to radius of curvature effects.

An error Analysis of R-C Timers
The results of this paper show that a variation is sensing voltage produces an error in timing which increases logarithmically with time interval. Also, variation in supply voltage produces the same type of errors, but the errors are decreased by the ratio of the sensing to supply voltage. An interesting conclusion from this analysis is that if the ratio of supply to sensing voltages is maintained constant, no change in timing will result.

Behavior of Transistors in a Magnetic Field
Experiments are described which show that magnetic fields can exert a controlling influence on the operating characteristics of point contact transistors. The effect is especially evident when the transistor is operated in its negative resistance region. The frequency of an oscillator can be varied, or a switch made to trigger by applying a magnetic field to the transistor. Some applications of the principle are suggested; many more are evident.

Low Speed Wind Tunnel Tests of Several Airfoil Sections Through 360 ° Angle of Attack
A series of two-dimensional airfoils were run through a complete 360 ° angle of attack range to determine their low-speed force characteristics. The airfoils were chosen in an attempt to vary as many parameters (such as thickness, camber, thickness distribution, etc.) as possible with the limited number of shapes that time permitted. All airfoils tested had lift curves with two distinct stalls and quite similar drag curves between 0 ° and 90 ° angle of attack. The highly cambered sections developed peculiar characteristics in the inverted and trailing edge forward positions, as might be expected. The effective test Reynolds number of 0.81 x 10(6) based on the model chord of one foot.

A Comparison of the Neutron Yields from Low-Voltage Sources
The description of the thick-target neutron yields from the D(t,n)He4 and the D(d,n)He3 reactions is calculated as a function of the energy of the bombarding particles. For 60-kev particles the ratio is 108. I increases to 168 at 100 Kev and to 194 for 120-kev particles. A qualitative discussion of the yields from various deuterium target leads to the conclusion that the greatest yield would come from the target which has the lowest stopping cross section per deuterium atom.

The Shape of a Shock Wave Derived from a Spherical Shock Wave Incident on a Concave Wedge
When a one-half ounce spherical charge of high explosive is detonated over a flat plane bounded by a 5 degree incline, the type of phenomenon encountered depends on the distance from ground zero to a beginning of the incline. If this distance is 48" the wave assumes a smooth contour on the plane. Detailed investigation of the shock velocity above the plane reveals that there is a pressure gradient along the shock front for a considerable region which replaces the usual triple point.
