Analytical methods and results

Description: Report detailing the analytical methods and results of a study designed to measure the total alpha particle activity of samples. The method being used was previously in use at Columbia University. The report recognizes potential for grave errors, but makes no effort to minimize the effect of the roughness of the sample.

Abrasive Blasting for Cleaning Parts

Description: Abstract: A demonstration on August 22, 1945, showed that Alpha or Beta M or K parts, including insulators, can be well cleaned with a pressure-feed abrasive blaster. The abrasive is a slurry of alumina and water mixed with high velocity air in a special feed nozzle. The slurry is continuously recycled.

Consolidation and shaping of boron ; summary of previous work

Description: From abstract: "The deposit on the rods is in the form of a brittle uneven tube which is cracked off and subsequently pulverized to a 200-mesh powder. This report is chiefly concerned with methods of consolidating this powder and shaping it into forms required, though it also discusses to some extent other methods of shaping boron or born-rich materials."

Cleaning E-Units by Blasting

Description: Abstract: An air-water-abrasive blasting system thoroughly cleans copper parts of E units without damage to the parts. Little abrasive is required because of the continuous recycle of the abrasive slurry.

The Chlorination of TO₃

Description: Abstract: The applicability of specific mixtures and organic chlorocarbons in general toward the chlorination of TO₃ has been tested by means of reactions is sealed glass tubes. The results show that thionyl chloride mixed with tetrachloroethylene or a bromothane of the tyoe CHBrC12 will produce TCI4 directly. This same result is produced by CBr2C12 alone.
