The 40s – From mechanical to „electrical machines“

The first electronic television image was presented in 1930. The first worldwide transmission took place at the Olympic Games in 1936. The cathode-ray tube – the basis for the development of radio and television, is also a constituent part of any oscilloscope and hence played a considerable role in the development of balancing. Electronic measurements became a reality. In the beginning they had a more experimental character, but this evolved to mean that with this technology unequal more precise results were achieved.

In 1935, a machine patented in the USA, featuring electrodynamic vibration sensors and stroboscopic determination of the unbalance angle, pioneered a changeover to a new design.

In 1942, Schenck was granted a patent for a “Method and facility for dynamic balancing by determination of the angular position of unbalance by means of a periodic curve displayed on the screen of an oscilloscope.” Due to its high accuracy the system was used right through the Second World War for balancing gyroscopic stabilizers for naval vessels.
