Peer reviewedRomanec, Michael J. – Journal of Chemical Documentation, 1974
The boundary between two neighboring rings is called the fusion lines, which is enclosed by external segments called arcs. In the code, the separation of fusion line(s) from arcs takes place in such a way that proper matching is achieved. By this procedure, the structure of a compound is recreated. (Author)

Peer reviewedFeldman, Alfred – Journal of Chemical Documentation, 1973
A Teletype Model 37 machine has been modified for the coding of chemical structures. The coding rate of this model is higher than that of other machines of this type. The rationale for choosing this particupar type of input equipment is presented. (6 references) (Author/SM)

Peer reviewedPrice, D.; Fitzpaynes, J. Y. L. – Journal of Chemical Documentation, 1973
The establishment of a reference filing system, based on optical coincidence retrieval, for an eight-man research group studying gas reactions is described. The complete system is simple to use and gives rapid, precise reference retrieval. (1 reference) (Author)
