A transmission system () comprising at least one floating gear () rotationally mounted upon a first shaft the system comprising a floating gear activation system for controlling torque transfer between the at least one floating gear () and the first shaft (), the gear activation system comprising a first device () having a friction interface () for frictional engagement with a friction interface () disposed on a first side of the at least one floating gear (), and a second device () having a locking interface () for an interpositional engagement with a locking interface () disposed on a second side, opposing the first side, of the at least one floating gear (), whereby the floating gear () is rotationally coupleable to the first shaft () by the friction interface () and/or the locking interface ().

Transmission system

A method for recovering and recycling excess hydrogen from process vent streams in the production of highly pure terephthalic acid where the production of the pure terephthalic acid comprises catalytically hydrogenating impure terephthalic acid, which typically contains 4-carboxybenzaldehyde (4-CBA), color bodies and other impurities, in aqueous liquid phase solution at elevated temperature and pressure.
