Pneumatic and Hydraulic Control Systems, Volume 2, documents the proceedings of a symposium on pneumohydraulic automation. The symposium is a continuation of the first symposium of papers on pneumohydraulic automatics which was published in 1959 by the Academy of Sciences, USSR. The present collection forms part of the lectures and reports presented at the second and third All-Union Conference on pneumohydraulic automatics and embraces a wide range of problems associated with the design and application of pneumohydraulic equipment in the automation of industrial units and other objects.
This volume contains 23 chapters organized into four parts. Part I contains papers on the general problems of pneumo- and hydro-automatics. Part II presents studies on pneumatic and hydraulic methods and systems of automatic regulation. Part III is devoted to pneumatic computing devices and methods of computation. The papers in Part IV cover pneumo- and hydro-automatics in the German Democratic Republic and Czechoslovakia.
