[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.

Summary of research of the section on pharmacology. Progress report for December 1944

Date: December 31, 1944
Creator: Hodge, H.C.
Description: Various studies relating the biological and behavioral effect of several uranium fluorides and chlorides as well as fluorine and oxyflourides are related. Most of these studies involved rats, guinea pigs, rabbits or dogs. Route of administration included inhalation, ingestion, or application to the skin.

A summary of the fission product metabolism studies up to March 1944

A summary of the fission product metabolism studies up to March 1944

Date: March 30, 1944
Creator: unknown
Description: The metabolic properties of the carrier free long lived fission products in the adult rat have been investigated at different intervals ranging from one to sixty-eight days following administration of the radioactive material. The radio elements studied include the most important long lived fission products, namely, Sr, Y, Zr, Cb, Ra, I, Xe, Cs, Ba, La, Ce, Pr, Np, and the unseparated uranium free fission mixture. The routes of administration included intraperitoneal, intramuscular, oral and intrapulmonary. The tissues assayed for the distribution of the administered radio elements included heart, liver, kidney, testes, spleen, muscle, skin, stomach, small intestine, large intestine, bone, blood, lungs, brain, fat, adrenals, lymph nodes. Urine and feces were collected separately at daily intervals for assay. Data acquired is provided in tabular form. For the fission products which were poorly absorbed from the site of both intramuscular arid intraperitoneal injection (namely, Y, Zr, Cb, Ru, La, Ce, Pr, Np, and the uranium free fission mixture) only the intramuscular data are given here and it is expressed in terms of the distribution of the fraction absorbed from the site of injection. For the radio elements which are completely absorbed following intraperitoneal and intramuscular injection or are absorbed in ...

A Concise Theoretical Method for Profile-Drag Calculation; Advance Report

A Concise Theoretical Method for Profile-Drag Calculation; Advance Report

Date: February 1, 1944
Creator: Nitzberg, Gerald E.
Description: In this report a method is presented for the calculation of the profile drag of airfoil sections. The method requlres only a knowledge of the theoretical velocity distribution and can be applied readily once this dlstribution is ascertained. Comparison of calculated and experimental drag characteristics for several airfoils shows a satisfactory agreement. Sample calculatlons are included.
