1914 The hydraulic system of marine transmission developed by Dr Fottinger was more flexible in engaging reverse thrust than the mechanical system but was less efficient; it had been fitted in the Koenigen Luise and was to be tested in the liner Tirpitz; Beardmores had made arrangements to manufacture the transmission at their Clyde works[1]. The system was particularly appropriate for use with turbines[2]
