Guidelines for text reduction were developed and evaluated to advance the art of manually preparing informative abstracts. The study was intended to: (1) develop guidelines that result in abstracts which provide maximal support to abstract-users, and (2) develop these guidelines so that they result in reliable, i.e., consistent, abstracts of scientific/technical material. The abstracting procedure, and Abstracting Form and associated instructions, produces reasonably consistent abstracts. An expert judge rated 13 subsections of six technical papers prepared by three different abstracters as 88% consistent, i.e., contained identical information. The abstracts prepared were a substantial reduction of the original text. Considering the six abstracts used in a performance test (judged as containing the most information, but not necessarily the longest) mean percentage reductions obtained were: 47% reduction of words, 28% reduction of figures, and 27% reduction of equations. Level of performance, as measured by accuracy on use-tests, supported by abstracts was equivalent to that supported by original text, regardless of test time restriction. However, total test time required was less using abstracts than with full text. (Author).

A series of catalysts were evaluated for effectiveness in initiating hydrazine decomposition near room temperature by means of differential thermal analysis. The most promising catalyst, Girdler T-323 with 50 percent pre-reduced cobalt on a kieselguhr support, was capable of initiating decomposition at 33 C and re-start at 53 C. Even with this catalyst, the ammonia produced can be expected to exhibit strong ADSORBTION PROPERTIES AND CONSTITUTE A CATALYST POISON FOR SUCCESSIVE RE-STARTS. A catalyst is needed to complete the decomposition of hydrazine to nitrogen and hydrogen. (Author).
