Abstract
AbstractThe Termatrex information retrieval system marketed by the Jonkers Business Machines, Inc., uses large plastic cards containing drilled holes. Duplicating the plastic cards to make identical copies for distribution requires multiple drilling and is costly, time‐consuming, and error‐prone. The Eastman Kodak Company has developed a method of photographing the plastic cards on cut sheet film approximately one‐half the dimensions of the Termatrex cards. The film sheets can be manipulated in the same manner as the original plastic cards. The problems of supplying duplicate decks is easily handled by photographic copies of one original Termatrex deck.
