Building 313 operations

Description: On June 3 the writer was detailed to the 300 Area to study operations in Bldg, 313. Seven days were spent with C shift in the caning and dipping area. In this period, a system of coordinating press cycles was developed to utilize machine time most effectively. Subsequently, a brief amount of time was spent working in a design of the can cleaning area so as to incorporate the aluminum can etching operation and facilitate the handling and flow of materials. The next stage of perhaps a week was de… more

100 Areas technical activities report - physics, December 1946

Description: This report summarizes physics experiments carried out in different parts of the 100 area at Hanford during December, 1946. This included work on the D pile, F pile, and experiments aimed at studying the irradiation properties of graphite and metal samples exposed to different radiation environments. Pile tests included reactivity tests, calibrations of control rods, and power coefficient tests.

Graphite expansion committee meeting of October 4, 1946

Description: Recent data show that test hole samples out from the center of a bar show greater expansion rates than do samples out from the edge of a bar. The previously noticed irregularities in expansion of test hole samples are attributed to this phenomenon. For unexplained reasons, the expansion of the graphite piles is in close agreement with the smaller expansion rates shown by test hole samples rather than with the larger rates. It is recommended that the neoprene coal on the far side of the F pile b… more

Spectral Lines of Curium from 3100 A to 4200 A

Description: Fifty-four spectral lines of curium are listed together with estimated intensities. A brief description of the manner of taking the spectra and of measuring the lines is given. Three separate samples of curium, in all seven micrograms, were submitted for spectrochemical analysis. The samples in acidic solution (HCl) were evaporated on copper electrodes and analyzed as outlined for the copper spark method. An Applied Research Laboratories spark source was used. The spectra were taken on a Baird … more

Stars in Photographic Emulsions Initiated by Deuterons Part II. Theoretical

Description: The theory of high energy nuclear stars depends on a theory of nuclear transparency and on a theory of nuclear evaporation. The transparency can be computed on the basis of a model proposed by R. Serber as soon as the interactions between the nucleons and the incident particle are known. The evaporation can be computed on the basis of the statistical model of the nucleus as soon as the nuclear entropy and binding energies of the evaporated particles are known. With approximate values for the ab… more

Master-Slave Manipulator

Description: A device for manipulating a pair of tongs behind a shielding barrier has been built and tested. It is called a Master-Slave Manipulator because the slave tongs move in exact correspondence with a master handle. The "slave hands" follow the master hands in complete synchronism. This is the first completely master-slave manipulator known to exist and has proved that this type of manipulation is very successful when the unit is prooperly engineered and built.

Comparison of Normal Process and Single Process (XC) Uranium

Description: Certain difficulties have been encountered in attempts to substitute a 'one-step' casting process, developed at Iowa State College, for the 'normal' process generally used for the production of extrusion billets. In the 'one-step' process molten metal is delivered from the reduction bomb to the billet mold instead of allowing the metal to solidify in the bomb with subsequent vacuum remelting of the biscuit metal before casting in the billet mold. Routine analyses had failed to establish signifi… more

Beta M2 Slit Support

Description: A new G slit support utilizing the standard G carbon now in use in all Beta production buildings was tested over approximately four months in the Pilot Plant with very successful results. A considerable saving has been made both in servicing time and in costs. The equipment has proved to be the best of any tried from the standpoint of run terminations due to alignment difficulties.
