Application of Punch Cards

Abstract

847an abrasion loss of 3.57 cc. per hour, then the horsepower required to produce a loss of 0.28 cc. per hour should not be greater than cates that when there is serious contamination extraction introduces a radical change in the results on the abrasion machine.

Punched-Card System for Tabulation of Crystallographic Data

“…The card used is a standard punched card overprinted in the center with the patterns shown in Figures 2 and 3. The data are entered on the cards according to the conventions established for publication of the Crystallographic Data section in Analytical Chemistry (1). A separate card is Figure 4.…”

Microscopic Fusion Analysis of Sterols

“…Identification of an unknown from information available in this form should be relatively rapid. A recent publication (2) has shown how similar data, for crystal optics, may be conveniently indexed on such cards.…”
