The labor-intensive nature of polymer tensile and flexure tests makes them logical candidates for automation. We have developed a fully automated instrument for performing these tests on rigid materials. The instrument is comprised of an Instron universal tester, a Zymark laboratory robot, a Digital Equipment Corporation minicomputer, and custom-made accessories to manipulate the specimens and measure their dimensions automatically. Our system allows us to determine the tensile or flexural properties of over one hundred specimens without human intervention, and it has significantly improved the productivity of our laboratory. This paper describes the structure and performance of our system, and it compares the relative costs of manual versus automated testing. 

Several exciting technical advances fostered the improved environment for computer use at pharmaceutical companies in the 1980s. The first was a development of the VAX 11/780 computer by Digital Equipment Corporation (DEC) in 1979. The machine was departmental size, that is, the price, dimen-... 

In both instances Bos employed a Digital Equipment Corporation PDP 11 computer on-line with a Radiometer polarographic stand with drop-life timer, a three-electrode system (DME, reference and Hg pool), two A/D and three D/A converters, together with a DEC writer and a recorder. For the "computer polarograph he used a Radiometer P04 polarograph and an external clock, and the computer had to perform the following functions ... 

This work was partially supported by an International Research Scholarship from the Howard Hughes Medical Institute (to G.B.) and by a collaborative research grant from Pfizer Central Research (to G.B.). Digital Equipment Corporation generously loaned the Alpha workstations used for the calculations. Riccardo Destro kindly made the l-alanine diffraction data available to us. Thanks are also due to Mark Spackman, Carlo Gatti and Eric de La Fortelle for useful discussions. 

The authors wish to thank Digital Equipment Corporation for financial support for this work and Dr. Collins Conley for his technical assistance.

The path taken when the search is started at k. = 0.5/min and k.sO.5 4/mol/min is shown in Figure 3. This search begins on a steeper slope and the function, in this case, spirals in on the minimum value. Again the correct values of k. s 1.0/min and k = 1.0 ,/mol/min are found. Total computer time for this analysis averaged 3-5 minutes with a Digital Equipment Corporation PDP-11/44 minicomputer. 

Elllpsometry. The automated ellipsometer is essentially equivalent to that described by Hauge and Dill ( 9). Data acquisition and analysis was made through the use of a Digital Equipment Corporation MINC 11/23 computing system. The detailed description of the system was reported previously ( 8). The measured ellipsometric angles and 4 are converted into the...

Computer Hardware. The use of a computer for data acquisition and control is mandatory because of the clock frequency used by the Reticon array (20 kHz) and the volume of data that it is capable of outputting. A PDP-8e computer made by Digital Equipment Corporation, with 12 K words of memory was employed.

International cooperation had become the rule in universities and research institutions. Computers became cheaper so that it became possible to purchase minicomputers such as VAX 11/780 (Digital Equipment Corporation), Perkin-Elmer 8/32, or Convex C220 for dedicated purposes. For a number of theoretical chemistry groups, this helped them to become independent of the long queue of users at their university central computer. In addition, access over a network to machines at a remote site became realistic, even if it was only via a 1200-baud special telephone line. For these reasons the...
