A Note on the Kinetics of Homogeneous Piles

Description: Abstract. In investigating stability of a homogeneous pile it has been customary to assume that the production of bubbles follows the production of power instantaneously. Here we investigate the implications of introduction of an intermediate dissolved gas stage under two hypotheses on the formation of bubbles from this dissolved gas. It is seen that this additional stage tends to make the pile unstable.

Factors Affecting the Precipitation of Tubanyl Peroxide from Gunk Solutions at Reduced Temperatures

Description: This paper reports work carried out to determine the factors necessary to give a filterable precipitation and determine the effects of these factors on the quantitativeness of the precipitation, and how any tendency to increase the tuballoy solubility may be overcome.

A Solubility Method of the Determination of Non-Volatile Material in Tetrachloride Charges

Description: Abstract: "This report suggests using methyl acetate extraction of charge material as a means of determining the non-volatile residue. It is shown that the volatile constituents of charge material are all extremely soluble in methyl acetate whereas the non-volatile materials are quite insoluble. Percent NVH on several samples of charge material by this method are reported and discussed."

Development of Equipment for the Purification of Mercury by Distillation

Description: Abstract: "An investigation of the mercury salvage program has resulted in the development of an improved high compacity type of distillation apparatus. The still, electrically heated and essentially automatic in its operation, will produce at a rate greater than 75 pounds per hour and develop a product 99.99% pure or better. This still will handle the lowest grade crude of amalgam that can pass through the feed lines and will continue to develop a pure prodcut for comparatively long periods of… more

The Solubility of Helium in Tuballoy

Description: This technical report summarizes the work done in attempting to determine the solubility of helium in tuballoy. In general, the method used has been to allow the tuballoy to stand in contact with helium at one atmosphere presume at a fixed temperature for an extended period, then to pump off the excess helium to a low pressure in as short a time as possible (10-6 mm of Hg or less). The system was then closed off and the pressure increase was measured by a suitable gauge as a function of time.… more
