Boiling Points and Surface Tensions of Mixtures of Benzyl Acetate With Dioxan, Aniline and Meta-Cresol

Description: Technical report. From Abstract : "Accurate measurements on boiling points and surface tensions of mixtures of benzyl acetate with dioxan, aniline and meta-cresol over the entire range of concentration are reported. The results have been analysed in terms of quasi-crystalline model which is partially successful in representing the composition dependence of heats of mixing, boiling points and surface tension except for composition dependence of boiling points of benzyl acetate and meta-cresol."

Crystal Structure of Bis (Meta-Chlorobenzoyl) Methane

Description: Technical report. From Abstract : "The determination of the crystal structure of bis(meta-chlorobenzoyl)-methane was undertaken by x-ray methods in an effort to clarify the ambiguous position of the hydrogen atom on the enolic form of β - diketones and hence in intramolecular hydrogen bonds."

The Crystal Structure of Bis(Meta-Chlorobenzoyl) Methane

Description: Technical report. From Abstract : "The crystal structure of bis(meta-chlorobenzoyl) methane has been determined by three dimensional anisotropic least squares refinement of scintillation counter data. The molecule was found to be nearly planar with a maximum deviation from the least squares molecular plane of 0.068Å and an average deviation of 0.023Å. Fourier transform techniques to locate phenyl rings provided the key to the structure determination. The intramolecular bond distances and thermal parameters of the oxygen atoms support a resonant, enol ring with a symmetric, intramolecular hydrogen bond. The structure confirms conslusions from the structure of bis(meta-bromobenzoyl) methane where the symmetry of the molecule was forced by the crystal symmetry."

Design and Test of a Diaphragm Pump for Liquid Metals

Description: Technical report. From Abstract : "Details are provided on the construction and operation of a two-stage diaphragm pump successfully used for the first time in liquid metal service. From the results of 5,376 hr. test of the pump it was concluded that it is well suited to the pumping of liquid metals at low flow rates where pulsating flow can be tolerated and also where remote operation is required. Operating temperatures and pressures are limited only by the availability of suitable materials of construction."

The Enhancement of Acidity of Very Weak Acids in Tertiary Butyl Alcohol

Description: Technical report. From Abstract : "The acidity of a solution of acid, HX, and salt, MX, is affected by both the concentration of X- and M+ owing to incomplete dissociation of the salt, MX. it was possible to increase the acidity of a solution of 2,6-di-tert-butylphenol - tetrabutylammonium 2,6-di-tert-butylphenolate relative to a dilute solution of tetrabutylammonium hydroxide by increasing the tetrabutylammonium bromide content. This indicates that the dissociation constant of the hydroxide base is sufficiently large that extensive dissociation occurs in dilute solutions. The addition of tetrabutylammonium bromide is therefore recommended as a general method for increasing the acidity and improving the titration characteristics of extremely weak acids."

An Experimental Approach to a Simplified Band Structure of the Rare Earth Metals

Description: Technical report. From Abstract : "A number of the physical properties from which we can obtain both direct and indirect information concerning the band structures of metals, have been measured for most of the rare earth metals. It was thought that it would be desirable to review ans examine these data and try to tie them together. For this purpose the very low and room temperature heat capacities, Hall coefficients, magnetic susceptibilities, spectral data and electrical resistivities were examined."

High Purity Calcium

Description: Technical report. From Introduction : "For more than a century, methods employed in preparing calcium were based largely on electrowinning and the most successful were based on [Sir Humphrey] Davy's process. ... In general, the metal was of adequate quality for the industrial applications of the time, and although by 1940 some strides had been made in the purification of calcium, interests in the better grades of the metal were limited essentially to experimental work of academic concern."

III. Crystalline Complexes of Bis(Di-2-Ethylbutylphosphinyl) Methahe With Uranium(VI) Nitrate and With Thorium Nitrate

Description: Technical report. From Abstract : "Bis(di-2-ethylbutylphosphinyl)methane, EBDPM, forms complexes with uranium (VI) nitrate and thorium (IV) nitrate in which EBDPM acts as a bidentate ligand and the nitrato groups appear to be coordinated. The complex with uranium (VI) is a monomer, UO2(NO3)29EBDPM), while the complex with thorium in a dimer, [Th(NO3)4]2(EBDPM)3. Both complexes are of high thermal stability."

Indicator Transition Ranges in Tertiary Butyl Alcohol

Description: Technical report. From Abstract : "The approximate transition ranges of a number of common indicators in tertiary butyl alcohol are given in terms of potentials measured with a glass-two phase salt bridge-SCE electrode system. Potential control was obtained by the addition of a sulfuric acid-malonic acid mixture and titration with tetrabutylammonium hydroxide. In general, the sulfonphthaleins are recommended for the titration of strong to medium strength acids, and Azo Violet, o-nitroaniline, and a p-nitro-p-aminoazobenzene for very weak acids."

Magnetic Properties of Some Intra-Rare Earth Alloys

Description: Technical report. From Abstract : "Paramagnetic susceptibilities of samarium structure alloys in the systems La-Gd, Nd-Y, Nd-Tm, and Ce-Y were measured from 4.2 - 300°K to determine what effect the formation of this structure has on the magnetic properties of the alloys. Susceptibility maxima were observed in the Nd-Y and Nd-Tm alloys, at 34.5 and 28.5°K, respectively. Slope changes were observed in the curve of 1/x versus T for the La-Gd alloy at 155 and 130°K, and the susceptibility of this alloy remained temperature-independent from 130-7°K. A rather poorly defined region of constant susceptibility was also observed or the Ce-Y alloy, from 26-37°K. Above these transition temperatures, the alloys obeyed the Curie-Weiss law, the susceptibilities of the La-Gd and Ce-Y samples indicating the possibility of electron transfer occurring in these cases."

I. Niobium(IV) Bromide and Pyridine Adducts of the Niobium(IV) Halides

Description: Technical report. From Abstract : "Reaction of NbBr5 and niobium metal in a sealed tube under a temperature gradient from 410° to 350° gave NbBr4 in good yields. However, an increase in the higher temperature from 410° to 450° was sufficient to eliminate NbBr4 as a product and cause deposition of a lower bromide."

Process Simulation on a Digital Computer Using Analog Methods

Description: Technical report. From Abstract : "A system has been developed to program a digital computer in much the same manner as an analog computer is programmed. Properties of a general purpose analog computer and a digital differential analyzer are combined to yield a program which employs, as input, standard data cards prepared from a diagram analogous to an analog computer diagram. The capacity of the system is much greater than that of most analog computers, making it applicable to large simulation problems. No scaling is required. The system is compatible with the Fortran symbolic language and may be used as part of a larger digital computer program. It may be applied to the more general types of boundary value problems arising in process simulation in addition to the initial value problems ordinarily solved on analog computers. It is particularly well adapted to non-linear problems and to control problems involving large transport delays. The program operates in basic machine language and, when used by itself, requires no compilation time."

Description: Technical report. From Abstract : "An instrument for measuring the propagation velocity of capillary ripples to within 0.3% and for measuring the amplitude of such ripples to within 1 to 10% (depending upon amplitude) was designed and constructed. The principle components of the instrument were a Teflon Langmuir trough (with provision for automatic recording of compression data); generating and receiving probes consisting of a thin rod and a razor blade respectively mounted so that the rod and razor edge were parallel and accurately placed in the surface to be studied."
