"Effects of High-Pressure Hydrogen on Steels."
Hydrogen embrittlement of steels is hardly a new subject, but the effects of high-pressure hydrogen have been treated in detail only more recently and to a much more limited extent. Thus, most investigations of hydrogen embrittlement have been concerned with hydrogen in metals, while for the high-pressure hydrogen problem, we are more concerned with metals in(in contact with) hydrogen. I believe there is a difference and, certainly,different mechanisms of embrittlement are at least possible.; Presented at the Central Florid Section, American Welding Society, Orlando, Florida, 14 November 1967 and North Alabama Chapter, American Society for Metals, Huntsville, Alabama, 16 November 1967. -

Correspondence between Oscar Goldsmith, John A. Chapman, and W. H. Halsey regarding property price negotiations.
These letters detail a chronological correspondence between Oscar Goldsmith and John A. Chapman, his agent, regarding negotiations to purchase property on Meridianville Pike from W. H. Halsey. The letters between Chapman and Goldsmith discuss reasonable price offers and "fancy" price Halsey wants for the property. In the end, Halsey writes a letter detailing the final transaction and cost. -
"Saturn Apollo guidance error estimation."
A brief sketch of the development of the equations for a weighted least squares estimator is given, the equations for both collective and recursive estimators being included. Four possible problem sources that may be encountered in the application of the estimator are identified. Various "success" parameters are defined in an attempt to predict the success with which, the method has been applied. The application of the estimation technique to the problem of computing various error parameters associated with the ST-124M guidance platform is described with the numerical results obtained using a manufactured data case are presented. These results are used to form conclusions about the effectiveness of the "success" parameters and preferred approaches to the problem of system evaluation using techniques of estimation theory.
