Technical Progress Report
"Discussions on the high-speed computer program include test control design, core storage unit, magnetic drums and tapes, paper tapes, slow circuits, exponent and main arithmetic units, flow charts for arithmetic control, and speed independent designs. Work done in the circuit research program includes flow-gating systems tests and two-wire low swing circuits. Mathematical methods are described for experiments with a floating-point differential equation solver. Switching circuit theory developments involve simplification techniques for Boolean functions, estimates of the maximum number of prime implicants in Booleans functions oi N variables, a formal algebra for linear graphs, and a technique for obtaining all maximum nodal normal subgraphs of a linear graph. Automatic reduction methods are described for bubble chamber photographic data. The operation, programming, and usages of the ILLIAC and the IBM-650 are described."

Electrical and Optical Investigation of Charge-Carrier Trapping in Rutile Single Crystals
"Low-frequency absorption centers, observed by electrical measurements in single crystals of rutile, can be produced by thermal quenching or optical irradiation in the edge of the eigen absorption region (600 A). They are observed when electric fields are applied parallel to the optic axis (crystallographic c axis) and are not visible with the field perpendicular to this axis. The temperature dependence of the principal dispersion indicates an activation energy of 0.18 ev. The centers can be explained by a localized electron transfer process along the optic axis. The introduction of silver and copper by thermal diffusion did not produce low frequency absorption spectra."

Photoelastic Study of Stress in Perforated Hemispherical Closures for a Pressure Vessel
"Photoelastic ''frozen stress'' tests were made of perforated hemispherical closures for a pressure vessel. Three different hole patterns were investigated. The ''circular'' and ''square'' arrangements of holes showed the highest peak stress, a value of stress + pressure of about 10 being noted in each. In comparison, the ''triangular'' arrangement of holes yielded a peak value of 8.20."

Elastic Scattering of Protons and Neutrons by Deuterons
"It is shown how a momentum space formulation of the p-d and n-d scattering problem makes possible a good calculation of the no polarization approximation. Calculations are carried out for a central Yukawn shaped Serber potential for values of the angular momentum L-o-6 in the energy range 0-95 Mev. These show that Born's approximation is not a good approximation at any energy, even for L-3. It is shown that a Fredholn approximation reproduces the results of the no polarization approximation for L > 1. The results are compared with those of Christain and Gammel and the experimental data."

Annual Report ONR Project A-2049
"The objective of this program is to conduct a broad basic program of analytical and experimental research into the fundamental behavior of gas- lubricated bearings and to establish general design criteria for these bearings. The work to date has included both theoretical and experimental phases of hydrodynamic and hydrostatic lubrication phenomena, supplemented by a digital computer program."

Final Stress Analysis of FHR Seed I Core I
"The structural analysis of the PWR Core 1 Seed 1 under prescribed thermal and mechanical loading with the object of predicting the structural reliability of the seed during actual service is described. Static and fatigue tests performed on fusion-welded Zircaloy specimens are described, and the results of these tests are incorporated in the reliability study. The applied stresses in the seed during operation of the reactor are quite low except at the end welds. Here, based upon the test data, a safely factor of about 4 1/2 appears to exist for 6000 cycles of loading."

Resin Attrition
"Uranium metal is produced by the bomb reduction of UF/sub 4/ with Mg. The slag from this reduction contains appreciable quantities of U, either in the metallic or the tetrafluoride form, in addition to the MgF/sub 2/. A process for recovering low enrichment U from this slag has gone into operation. A study of the causes of resin attrition and their relative magnitude both from an over-all point of view and with specific reference to the Higgins' Column and Dowex 21K resin is presented. Equipment was designed, assembled, and tested to investigate the effects of valve action, wall to resin and resin to resin friction, repeated chemical cycling, and column height. Certain mechanical properties of the resin beads were investigated, and some existing plant data were analyzed. A discussion of the probable mechanism of attrition and its contribution to the overall amount of attrition is presented."

Upper Atmosphere Monitoring Program
"An apparatus designed to test aerosol filter efficiency at pressures equal to or less than atmospheric and at linear face velocities of 5 to 1000 ft/ min is described. Aerosol collection efficiency studies were completed for IPC paper at 20,000 and 40,000 ft. Data developed in these studies indicate that ia the impaction and diffusion regions collection efficiency increases with altitude for all linear face velocities less than 800 ft/min. A propeller-type flowmeter, calibrated to measure the volume of air moved by a blower in a balloon-borne system, was flown on five separate flights to obtain air flow data. These data sre presented. Flowmeter air flow measurement data were approximately 10% lower than telemetered data."

Temperature and Phase Effects on the Photolysis of Ethyl Iodide
"The elementary steps in the photolysis of liquid ethyl iodide by light of wavelength 2537 A by determining initial rates of iodine production in the presence of added iodine and hydrogen iodide were analyzed at 25 and --70 d C to get information on the activation energies of competing elementary reactions. Investigations were also made of the effects of additives on the photolysis of glassy ethyl iodide at --180 d C, and evidence for the formation of trapped radicals during photolysis and radiolysis of the solid was sought by electron paramagnetic resonance measurements."
