Title: Anti-spinning device for automobiles

Abstract: The anti-spinning device comprises for each wheel a sensor delivering electric pulses proportional in number to the peripheral distance covered by the wheel, with a lower number of pulses in the case of a driving wheel, and at least one up/down counter receiving said pulses and co-acting with means for introducing a retard into the ignition system. Said means comprise between the contact breaker and the ignition elements proper a shift register for the breaker signal, a clock adapted to be released by this signal and controlling the successive shifts of the breaker signal in said shift register, and a multiplexer for selecting the original or retarded breaker signal, which is connected to the outputs of said shift register and responsive to a channel selector circuit responsive in turn to the state of said up/down counter. Said device may be applied for protecting against the spinning of driving wheels in a motor vehicle.
