Introduction: The objective of the study was to estimate the worldwide distribution of a few broad categories of naturally occurring materials found on the land surface of the earth.

Abstract: A rotary kiln was evaluated for the controlled oxidations of UC.

Abstract: The design and initial test of cutting and welding equipment developed to remotely cut and re-weld the bottom process tube joint are discussed in this report.

Report presenting a state-of-the-art survey of automatic indexing systems and experiments. It was conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including citation indexes. Advantages, disadvantages, and possibilities for modification and improvement are discussed. Experiments in automatic assignment indexing are summarized. Related research efforts in such areas as automatic classification and categorization, computer use of thesauri, statistical association techniques, and linguistic data processing are described. A major question is that of evaluation, particularly in view of evidence of human inter-indexer inconsistency. It is concluded that indexes based on words extracted from text are practical for many purposes today.

The following report presents the results of an engineering design study performed to investigate the potential and feasibility of a deep-pool reactor concept for ultimate use as an economic heat source for a single-purpose desalting plant.
