Critical Temperatures of Methane Aliphatic Hydrocarbon Mixtures. Interaction model postulated for methane-free
aliphatic hydrocarbon systems has been extended to mixtures containing methane. Calculated critical temperatures of binary, ternary, and quinary aliphatic hydrocarbon mixtures, compared with experimental values, showed an over-all deviation of 1.55% for 59 mixtures.

The Expansion and Inversion of Transfer Functions for Two Fluid Heat Exchangers. An expansion technique for transcen-
dental transfer functions of double pipe heat exchangers is presented. For the simple two-fluid heat exchanger with no wall capacitance, the expansion is inverted to give exact time domain impulse response in a closed form.

Calculations for four hydrodynamic situations: rotating disk, growing mercury drop, semi-infinite stagnant fluid, and Nernst diffusion layer; and for several electrolytic systems. Results are in the form of ratio I L / I D as a function of ratio of supporting ion concentration to that of counter ion.
A phenomenological model, based on the Prandtl mixing length theory, is presented to show the importance of turbulence in liquid film mass transfer processes.

Distillation Column Feedforward Controller Models Compared.
Four dynamic controller functions evaluated on basis of control of vapor composition leaving top tray. Simplest model with no transient compensation was highly effective. More complex second-order functions yielded greatly improved control with proper adjustment of controller constants.
Regimes of Mass Transfer with Chemical Reaction. Simple rules are stated by which any specific process can be identified as approaching the conditions of any one of five basic "regimes" of mass transfer with chemical reaction. Should help avoid unnecessary duplication of work.
