[Observation on machining speeds and feeds]

[Observation on machining speeds and feeds]

Date: March 2, 1944
Creator: unknown
Description: This memorandum describes a trip on February 17th, 1944, in which the author stopped at the Baker Brothers Machine Company in Toledo to get the latest information on machining speeds and feeds and to determine the validity of their reported three pieces per hour per machine. The Baker Brothers reported that the three pieces per hour figure is an average given for determining delivery dates and allows for machining shapes other than a straight cylinder. They recommended a speed of 360 RPM for turning with a .010 feed.

Project 9536, metal turnings - fire hazard

Project 9536, metal turnings - fire hazard

Date: August 27, 1943
Creator: unknown
Description: The turnings have proved to be highly inflammable and subject to spontaneous ignition. Several experiments have been conducted at Herring-Hall-Marvin Safe Company, Hamilton, Ohio, and Baker Brothers, Inc., Toledo, Ohio, and in addition there have been a number of accidental fires, of which at least three were spontaneous. Fires of quantities ranging from several pounds to several hundred pounds have been experienced and a number of extinguishers have been tried. Records of this work are available in our files. While the work to date does not constitute an exhaustive survey of the problem, we believe that it is now safe to outline precautionary and protective measures.

Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16--31, 1945: Summary of work to date on volatile neutron source

Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16--31, 1945: Summary of work to date on volatile neutron source

Date: September 6, 1945
Creator: Rollinson, C.L.
Description: It was proposed to prepare a volatile polonium compound which could be used alone or with another gaseous compound as a neutron source. The objective was to obtain a neutron source which would give off few neutrons in the expanded state, but when condensed would act substantially as a thick target and emit perhaps ten times as many neutrons. Originally, polonium hexafluoride was suggested; with such compound the fluorine atoms would constitute the target. the predicted boiling point of polonium hexafluoride is about -40 {degrees}C. There was reason to believe, however, that lower relatively non-volatile fluorides would be formed rather than the hexafluoride. Polonium alkyls were therefore proposed as alternatives. The predicted boiling point of Po(CH{sub 3}){sub 2} is about 110 {degrees}C. This compound in itself would probably not be suitable as a target material but it could be mixed with other gases such as carbon tetrafluoride, boron trifluoride, etc., as targets. As a longer range possibility, Po(CF{sub 3}){sub 2} was also suggested. This compound would act as its own target and would moreover have the same F/Po ratio as PoF{sub 6}; its boiling point could be expected to be 30{degrees} - 60 {degrees} lower than that of polonium dimethyl. ...

Determination of slug temperatures for various power levels

Determination of slug temperatures for various power levels

Date: January 5, 1949
Creator: Burda, E.J.
Description: This study was undertaken to determine the maximum temperatures that may be expected in slugs under various operating power levels. Information of this nature is required to properly evaluate the effects on the slug of pile operation at power levels higher than those currently in use.
