Typescript of an article on an experiment with a gas pressure-regulating point (GRP) control system in Baku in the 1960s

This deposit contains a typescript of a scientific and technical article by A. M. Abdullayev, G. M. Gurvich and Z. A. Kerimov on a full-scale experiment with an automatic control system for a gas pressure-regulating station (GRP) in Baku. The experiment was run at the “Kotly” dispatch point and lasted 11 months. Its operating data cover February–March 1966. The system keeps the pressure constant at a chosen point of the low-pressure network, 450 m from the station, and varies the station’s outlet pressure accordingly. The typescript survives in the personal archive of A. M. Abdullayev. Where and when it was published has not been established. The deposit includes scans of the eight typescript sheets, a preface by the depositor (about the source, the authors and the significance of the work), a Russian transcription, and English and Azerbaijani translations. The original has no figures, no list of references and no conclusion. Figures 1–3 are reconstructed from the text. The preface’s estimates of gas savings are the depositor’s own and are not stated in the original.
