    Abstract

    A small, stored-program, parallel-mode digital computer is used to process data from four tensile testing machines. Each tester is equipped with a stress encoder, strain detection system, keyboard, and teletype printer. The necessary parameters are entered on the keyboard and the specimen is positioned in the tester. A key is then depressed to start the tester and to activate the computer. The translation and transmission of the data are performed by the stress encoder and strain detection system. At the completion of the test, the data is printed in an easy-to-read tabulated format.

    There are ten on-line computerized tests performed on the tensile testers. Five of the tests have alternate program routines by which the data may be processed. In addition to the on-line program routines, there are eighteen off-line routines that are used. These off-line routines are primarily performed on remote stations consisting of a keyboard and teletype printer.

    The computer has decreased the chemist's data analysis time, increased the accuracy of the data, and decreased the amount of subjective data interpretation, thus resulting in greater efficiency.
