Abstract: A method and apparatus for controlling timing of an internal combustion engine having a piston located in a cylinder. The method and apparatus includes determining a first angular position of a crankshaft at a first location along a longitudinal axis of the crankshaft, determining a second angular position of the crankshaft at a second location along the longitudinal axis, determining a level of deformation of the crankshaft as a function of a difference between the first and second angular positions, determining an actual position of the piston as a function of the crankshaft deformation, comparing the actual piston position to a desired piston position, and controlling timing of an event to initiate combustion in the cylinder as a function of a difference between the actual and desired piston positions.

Abstract: The operation of the dividing wall section of a dividing wall column is controlled by a control apparatus comprising a ratio controller which divides the liquid flowing into the dividing wall section. The rate of return of overhead liquid to the column is set by monitoring the temperature in the top of the product dividing wall section and the sidecut product draw rate is set by monitoring a temperature in the bottom of the product dividing wall section.

Abstract: Construction and operational costs of simulated moving bed adsorptive separation process units are reduced by recovering desorbent from both the extract and raffinate streams of the process in a single column. Both streams are fractionated in the same column to recover desorbent, which is removed at the bottom of the column. The bottom of the column is divided into a reboiler sump section and a bottoms product-desorbent inventory section, with this reducing the equipment required in the overall process.
