It used coupled transformers, with numbers of turns digitally set up to +/-1000 and solved sets of up to 10 linear differential equations. It was built by Rawlyn Richard Manconchy Mallock of Cambridge University. The Mallock machine was contemporary with the mechanical differential analyser, which was also used at Cambridge during the late 1930s and 1940s. This volume contains Mallock's one and only article on the machine. SERIES A. VOL. CXL. No. A 840-April 1, 1933.Ñ Chemical Equilibrium in Vapour of a Mixture of Hydrocarbons. By H. A. Wilson, F. R.
