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.

Fractionation of Fission Products and Heavy Elements by Volatilization Methods
Technical report describing the attempt to separate the long lived fission product oxides by volatilization methods. A fractionization crucible was used. The fractionations give a fair idea of the relative volatilities of the longer lived fission products and also of the degrees of separation of the plutonium oxide or oxides from the fission products.

An Improved Continuous Ether Extractor for the Determination of Uranium in Dissolver Solutions
An improved continuous ether extractor is described. The modifications include a means of safely disposing of the active raffinate and a means of positivity checking the raffinate for completeness of uranium extraction. The results obtained on synthetic samples and on dissolver solutions are given. This work was undertaken because of a need for the determination of uranium in dissolver solutions with an accuracy of 0.1 per cent. After a review of available methods it was decided that a gravimetric determination would meet the requirements of precision and accuracy.

Constitutive modeling of Climax Stock granodiorite under compressive loading. [Rock samples from Nevada Test site]
Described here is a constitutive relation for the stress-volume strain states of Climax Stock granodiorite from the Nevada Test Site under nonhydrostatic loading conditions. By comparison with Nugget sandstone under similar loading conditions, for which this functional form fitted the data, we find no relationship for Climax Stock granodiorite between the fitting parameters and other system variables such as mean stress or confining pressure. Therefore this relation is not yet suitable for use in computer codes that attempt to predict the response of rocks to stress.
