Introduction

Tech Briefs are short announcements of new technology derived from the research anddevelopment activities of the National Aeronautics and Space Administration or the U.S.Atomic Energy Commission. These briefs emphasize information considered likely to betransferable across industrial , regional, .or disciplinary lines and are issued to encouragecommercial application.

This Index to NASA Tech Briefs contains abstracts and four indexes—subject, personalauthor, originating Center, and Tech Brief number—for 1974 Tech Briefs.

Abstract Section -

The abstract section is divided into nine categories: Electronics/Electrical; Electronic/Electrical Systems; Physical Sciences; Materials/Chemistry; Life Sciences; Mechanics; Ma-chinery, Equipment, and Tools; Fabrication Technology; and Computer Programs. Withineach category, abstracts are arranged sequentially by Tech Brief number.

A typical abstract entry has these elements:
