Abstract
Abstract A multiple product gasoline dispensing system having a cost counter for accumulating the cost of gasoline dispensed; a bank of three magnetic domain wire pulse multiplier switches for each product angularly settable for generating from 0 to 9 output pulses for each input pulse for establishing the amounts of the three places respectively of a three-plate unit volume price; a pulse generator for generating three pulse trains for operating the three multiplier switches of a selected switch bank having members of pulses in accordance with a geometric progression having a common ratio of 10; and a product selector at a fuel dispensing nozzle comprising a valve for establishing the product and a magnetic domain wire pulse multiplier switch for generating a pulse train having a number of pulses in accordance with the selected product for selectively activating the multiplier switch banks. Each pulse multiplier switch comprises a generally circular magnetic domain wire with a nucleation coil at one end, a pickup coil with separate angularly spaced coils and a settable rotor with a permanent magnet establishing the number of pulses generated by the pickup coil upon each operation of the nucleation coil.
