Joly-Arco alternator - In this machine, invented by Georg von Arco around 1911, the alternator produced its signal at a lower fundamental frequency, and the frequency was multiplied 2 to 4 times in separate magnetic frequency doublers, [3] invented by Vallauri [10] and Maurice Joly [11] in 1911, [12] a nonlinear transformer with its iron core ...
Three gearboxes were available with ratios of 2.675, 2.973 and 3.324 and the 900 RPM driving motor was operated at slips of 4% to 20%, giving speeds of 864 to 720 RPM. Transmitters installed in Europe, operating on 50 Hz power, had a wavelength range of 12,500 to 28,800 meters due to the lower speed of the driving motor.

This three-arm signal controlled junction has three vehicle phases (A, B and C) and a pedestrian phase (D). The phases operate together in three stages (1, 2 and 3). Moving phases are shown in green and stopped phases are shown in red. Phases are indications shown to traffic on traffic signal aspects (a single light on a signal head). For ...
