Abstract: 1,034,148. Semi-conductor circuits. NATIONAL CASH REGISTER CO. March 31, 1965 [April 27, 1964], No. 13719/65. Heading H3T. [Also in Division G4] Selected ones of a co-ordinate array of elements, e.g. solenoids 11 are energized by column and row driver circuits 14, 16, each incorporating a controlled rectifier in series with the corresponding elements across a potential source, the rectifiers being normally forwardbiased so as to product on application of a control pulse and to be reset by reversal of the bias. A solenoid 11 is energized when the corresponding pair of controlled rectifiers are triggered and de-energized when the bias is reversed. Each solenoid 11 is connected in series with a diode 12. Column and row selectors 17, 18 may each consist of a binary flip-flop register combined with a recoding network to mark the selected column and row lead. Column and row reset circuits 19, 20 are controlled by circuit 21. This may respond, for example, to a particular signal combination. Each solenoid energizing circuit, Fig. 2 (not shown), passes from the + 50 v. terminal 22, through the column reset circuit 19, driver 14, column lead 13, diode 12, solenoid 11, row lead 15, driver 16, row reset circuit 20 to earth terminal 25. In addition, back-biasing connections are made from the column leads 13 via diodes 30 to earth 25 and from row leads 15 via diodes 27 to the +50 v. terminal 22. Each driver has an input terminal 40 connected via resistor 41 to capacitor 43 and diodes 44. This arrangement prevents operation by spurious pulses. If an input pulse of - 8 volts is applied to terminal 40, transistor 48 conducts sending a charging pulse to capacitor 55 through the primary of transformer 50. The induced pulse in the secondary winding fires silicon controlled rectifier 61 to cause it to establish a conductive path between terminals 62 and 59. The reset circuit includes a silicon controlled rectifier connected similarly but adapted, when fired, to allow a charged capacitor to discharge through the primary of a transformer. The oscillation produced gives a spike signal at the secondary which is connected to the driver circuit to backbias the driver rectifier and cause it to cease conducting. The two reset circuits may share the same primary winding and control circuitry.
