Abstract: 1289543 Transistor switching circuits OWENS-ILLINOIS Inc 13 Aug 1969 [14 Aug 1968] 40458/69 Heading H3T [Also in Divisions G4 and G5] A pulse generator supplying firing pulses to a conductor N of a gas discharge display and/or memory panel (see Divisions G4-G6) comprises transistors Q1, Q2 and means to reduce spurious voltages applied to the transistors from the output-line N. On applying a pulse 34 to Q1, transistor Q2 passes current through primary winding 40 of transformer T1 to produce an igniting pulse on its secondary winding 42 connected to the line N. A second such pulse, when Q2 turns off, is prevented by diode D 1. Spurious voltages generated on conductor N by pulses applied to adjacent conductors induce a voltage in primary winding 40. When the voltage renders point 77 negative with respect to 76 current flows through the diode D1. When point 77 is positive both transistors Q3, Q4 become conductive and form a low impedance path.

A circuit for operating a discharge lamp K comprises a serially connected capacitive ballast C 1  having a triac T 1  and a resistor R 1  connected in shunt therewith. Gating potential for the thyristor is obtained from an RC phase shifting network connected in parallel with the lamp. When the circuit is connected to an A.C. source the triac T 1  triggers into conduction to short circuit the capacitor C 1  whereupon the whole supply voltage is applied across the lamp causing it to strike. When the lamp has struck the voltage across it falls, the triac then becoming non-conductive and the capacitor C 1  then acts as a ballast to maintain the lamp conducting. The triac may be replaced by back-tobaok thyristors. In other embodiments the gate potential for the triac may be obtained from a circuit which includes a half wave diode, the triac may be triggered by a second triac and finally a third triac may be included to open circuit the lamp filament circuit when the lamp has struck.
