Improvements in or relating to Encoding Information on Punched Record Cards and Other Equivalent Media.

This article presents information about a research paper "Improvements in or Relating to Encoding Information on Punched Record Cards and Other Equivalent Media," by Calvin Northrup Moores. It describes an encoding scheme which consists in a method of manufacturing a collection of units for use with a mechanical, optical or electrical selecting device each unit having a field for selection-controlling indicia for sensing by the said selecting device according to the pattern inclusion principle. Diagrams at the end of the paper illustrate several selective machines.
