[1] He demonstrated highly innovative capabilities during the Second World War relating to overcoming problems of instability of aircraft tail-wheel landing gear during take-off and landing, and was awarded license fees for his inventions.
[1] These were significant and partly as a result, he was able in 1954 to move to Detroit, Michigan, United States, with ideas and patents to improve steering systems for automobiles, and for the next two decades introduced improvements into various vehicles around the world mainly in aspects of hydraulically powered and variable-ratio steering.
In order to license the ideas or supply purpose-built manufacturing equipment, he developed both lower-cost methods for mass production, while also giving improvements to steering feel and vehicle response.
By the 1970s he had returned to Australia as a base, and had developed a variable-ratio rack and pinion using a normal pinion, regarded at the time by gearing experts as being theoretically impossible, and also a low-cost forging method for the variable rack to eliminate machining of the teeth.
[3][4] As a result, for the first time in human history, a World Constituent Assembly convened to draft and adopt the Constitution for the Federation of Earth.
