Effect of Temperature on Beta-Ray Measurements
Summary: "This report investigates photographic methods of measuring beta radiation and includes a study of temperature effects on these measurements. Experimental data are submitted to show that an increase in film temperature before and during beta irradiation causes a definite increase in density for the same dosage. Recommendations drawn from experience gained in the experimental works are offered."

Evaluation of Methods of Brazing Aluminum Spacing Fins to Flat-Plate Aluminum-Clad Fuel Elements
Abstract: "Four brazing methods and one other joining process were evaluated for the joining of aluminum spacer fins to flat-plate aluminum-clad fuel elements. None of these methods appear completely suitable for use in a mass-production operation. Furnace brazing and salt-bath brazing were most promising. However, the mechanical problems involved in the application of either process deter their recommendation. Resistance brazing and torch-brazing were proven impractical. The great difference in mass between the two pieces being joined prevents the use of either the resistance or torch method. Pressure bonding is not applicable because of the excessive deformation of parts being joined."

The Solvent Extraction of Thorium by Thenoyltrifluoroacetone and the Influence of Aqueous Complexation by the Chelating Agent
Technical report investigating the solvent extraction of thorium. The solvent extraction of thorium by the chelating agent, thenoyltrifluoroacetone (TTA), has proved to be a very effective tool for studying the complex ion chemistry of thorium. This study led to the establishment of the existence of aqueous complexation by the chelating agent.

Effect of a Decelerating Grid on Current from an Ion Source
Abstract: "A theoretical criterion is given for the conditions under which the ions from an ion source may be decelerated by a decelerating grid, following the accelerating grid which extracts ions from the emitter, without causing a reduction in the current supplied by the source."

Gravitational-Electromagnetic Torus Models of the Elementary Particles
Abstract: "A torus model of the elementary particles is suggested in which the electron and proton are made stable by gravitational forces derived from the electromagnetic field. It is suggested that the gravitational forces for the unstable particles, presumably the mesons, are not sufficient to keep the torus from expanding in the direction of its large radius. Rest energy zero can be achieved, presumably for photons and neutrons, when the gravitational energy and electromagnetic field energy are equal in magnitude. The manner in which these models can exhibit spin, magnetic moment, wave length, and phase velocity is indicated. The origin of nuclear forces from an electromagnetic basis is indicated."

Continuous injection processing
From introduction: "In this report we consider a few non-adiabatic processes. The types to be discussed will be limited because of two reasons: first, complete descriptions are available for some processes; second, as time goes on alternative injection methods undoubtedly will be discovered, so this list must necessarily be incomplete."
