The machines

Drawing of a centrifugal "fly-ball" governor. The balls swing out as speed increases, which closes the valve, until a balance is achieved between demand and the proportional gain of the linkage and valve
Cut-away drawing of steam engine speed governor. The valve starts fully open at zero speed, but as the balls rotate and rise, the central valve stem is forced downward and closes the valve. The drive shaft whose speed is being sensed is top right

A tortoise built to the M. Docilis specification i.e. with the conditioned reflex. The student who built it was Ewald Eichler and it was built as part of his diploma thesis -Ewald Eichler: Ein umuetlabhaengiger Automat (Travail de diplome a l’Universite techniquo de Vienne, 1954).
