Absorption of Organic Acids on Thoria

Description: The adsorption of acetic and oleic acids on the surface of thoria was studied by means of infrared spectroscopy. An infrared analysis of the adsorbates before and after adsorption using differential double bean methods indicated that the adsorption of organic acids on thoria surfaces occurs by an esterification reaction between the organic acid and the hydroxylated thoria surface. Ammonia vapor will not adsorb on thoria, indicated the basic character of the hydroxylated surface.

The Adsorption of He3 and He4 on Activated Charcoal

Description: The adsorption on activated charcoal of pure He3 at 2.5 and 3°K, and of pure He4 at 4°K has been measured. The volume of gas necessary to form a monolayer is approximately the same for the two isotopes. It is shown that capillary condensation does not occur in this adsorbent at low saturations. The data have been analyzed by a number of methods with consistent results.

An Aerodynamic Raindrop Sorter. Technical Progress Report No. 1.

Description: A pilot model of an Aerodynamic Raindrop Sorter was constructed along the lines suggested by mathematical analysis. The function of the analyzer is to sort natural rain according to drop size and to collect the sorted drops for further analysis. The pilot model, a small wind tunnel inclined at 45 deg to the horizontal, demonstrated the feasibility of aerodynamic rain drop sorting over a wide range of drop sizes. (auth)

Aerosol Collection by Wetted Fiberglass Media

Description: A wet collection system for aerosols has been developed using fibrous media. Tests show the performance to be in accord with recently developed theory of collection by fibrous media. The effects of varying aerosol particle size, particle density, and gas velocity have indicated that inertial impaction is the primary collection mechanism. Three-year operating experience on several full scale plant installations shows reliable performance.

Analysis of Spurious Modes in Magnet Power Supply

Description: "The resonant frequencies of the magnet power supply are investigated. It is found that there are eleven resonant modes in addition to the desired mode of operation with six additional resonant frequencies. From measurements of the choke model, it appears that the frequencies of some of the spurious modes may lie in the same range as the desired mode of operation."

Analytic Approach for the Pion-Proton Scattering Phase Shifts

Description: A simple method of solving for the phase shifts of the pion-proton scattering is presented. The rapid solution afforded can be utilized, as the Ashkin diagrams have been employed, to give starting values to an electronic computer or alternatively to analyze with more ease the variation of the phase shifts as a function of the input data in terms of the coefficients of the angular distributions. A new plot of a function of the total cross section versus the pion energy is introduced. The nearly … more

The Armour Dust Fueled Reactor (ADFR)

Description: "Work has begun on the ADFR, a reactor using a new fuel form -- fissionable dust carried in an inent gas. Temperatures in the range 2,000 to 3,000 deg F appear feasible in an all-ceramic system. Experimental study of the fuel form was initiated, and a loop to circulate the fuel dust was constructed. Initial operation is encouraging. Theoretical studies were carried on in the areas of reactor physics, heat transfer, and safety."

Automatic Thermogravimetric Analysis in Ceramics

Description: Ceramic investigators often find it desirable to know the weight of reactants either immediately after a given heating period or while the specimen is still at the elevated reacting temperature. The conventional gravimetric methods render either of these goals difficult if not actually impossible. Specimens often gain weight through adsorption of water or other reactions upon cooling to room temperature. Desiccators are employed but are not completely satisfactory. Repeated heating and weighing… more

Behavior of Bond Under Dynamic Loading

Description: The objectives of this research program are to determine bond strength under dynamic loading, to compare bond strengths under static and dynamic loading, and to test the adequacy of ACI Building Code bond requirements for structural elements subjected to blast loads. The tests have shown that local static bond strengths may be as high as 0.75 fc and that under dynamic loading this strength increases to fc. For all practical lengths of embedment of bars, steel failure is to be expected both unde… more

Behavior of Transistors in a Magnetic Field

Description: 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.

Betatron Oscillations and Equilibrium Orbits in Terms of Amplitude and Phase Functions

Description: "Formulas are given to express the general particle trajectory and the equilibrium orbit for a slightly disturbed synchrotron in terms of the amplitude and phase functions for the ideal machine. If these functions are known, orbit computations can be carried out by simple integration procedures. The formalism is expected to be useful especially for considerations such as beam alignment or generation of an external electron beam. Some equations given earlier are repeated for completeness."
