The Effects of Catalytic or Promoter Oxides on The Brin Process

Future generation high altitude aircraft will require logistics independent, on-board oxygen generation systems. In an attempt to meet this challenge the eighty year old Brin Process, BaO + ½O2 ↔ 750°C ↔ BaO2 , was re-examined using a laboratory breadboard model. The influence of eighteen oxides as reaction promoters was studied and the results of forty admixture experiments are evaluated. Observed behavioral trends can be explained based on geometric and electrochemical factors. An equal molar mixture of La2O3 and BaO does lower the reaction temperature about 100°C, increases the reaction rate, and improves the oxygen yield. The peroxide decomposition follows both first order and parabolic reaction kinetics. Plausible mechanisms are advanced for the reaction enhancements which are noted with La2O3 and MgO admixtures

Black-and-white photographic chemistry: A reference

This work is intended as a reference of black-and-white photographic chemistry. Included is a basic history of the photographic processes and a complete description of all chemicals used, formulas for the development and fixation process, and associated formulas such as cleaners, hardeners, and toners. The work contains a complete glossary of photographic terms, a trouble-shooting section listing causes and effects regarding photographic film and papers, and various conversion charts

Women and Chemicals at Work

Information packet on women and chemicals at work produced by the Women’s Occupational Health Resource Center (WOHRC). The WOHRC (1979-1987) was a research and training program devoted to identifying and better understanding hazards faced by women workers. WOHRC was housed in Columbia’s School of Public Health and directed by Professor Jeanne Mager Stellman. WOHRC was a designated OSHA New Directions Training program, and also received support from other federal and private agencies. As a New Directions project, WOHRC trained thousands of workers and professionals in hazard recognition and accident and illness prevention for women workers. In order to carry out its public health programs, WOHRC developed and disseminated original educational materials. The materials were designed to be authoritative while at the same time accessible to non-professional users (e.g. the workers). WOHRC published a monthly newsletter that contained a “fact sheet” focusing on a particular job or a particular hazard. The fact sheets were also made available individually or collected into “fact packs” of related materials

List of Bureau of Mines publications and articles, January 1, 1960, to December 31, 1964 with subject and author index

The Bureau of Mines was establis4ed in the public interest to conduct inquiries and scientific and technologic investigations concerning mining and the preparation, treatment, and utilization of mineral substances; to promote health and safety in the mineral industries; to conserve mineral resources and prevent their waste; to further economic development; to increase efficiency in the mining, metallurgical, quarrying, and other mineral industries; and to inquire into the economic conditions affecting these industries. The organic act of the Bureau, as amended by Congress and approved February 25, 1913, made it the province and duty of the Bureau to "disseminate information concerning these subjects 'in such manner as will best carry out the purposes of this Act.\ue2\u20ac?In accordance with that directive, the Bureau reports the findings of its research and investigations in its own series of publications and also in articles that appear in scientific, technical, and trade journals; in proceedings of conventions and seminars; in reference books; and in other non-Bureau sources. The number of these reports, the wide range of subjects they cover, and the variety of mediums in which they appear make the kind of list and index presented in this special publication both necessary and valuable. This issue describes Bureau reports and articles published during the period January 1, 1960 to December 31, 1964. It supplements the 50-year list of Bureau publications issued from July 1, 1910, to January 1, 1960, and the 50-year list of articles by Bureau authors published outside the Bureau from July 1, 1910, to January 1, 1960. It supersedes the annual lists of Bureau publications and articles from January 1 to December 31, 1960, from January 1 to December 31, 1961, from January 1 to December 31, 1962, and from January 1 to December 31, 1963.7The leading general and technical libraries of the United States maintain files of the Bureau's publications. A list of these libraries appears immediately following this introduction
