Transistorized ignition system

Claim 1

A KIT FOR USE IN STABILIZING THE COIL CURRENT IN AN IGNITION SYSTEM FOR AN ENGINE HAVING THE SERIES CIRCUIT ARRANGEMENT OF AN IGNITION PRIMARY COIL AND THE PARALLEL COMBINATION OF BREAKER POINTS AND IGNITION CAPACITOR NORMALLY CONNECTED ACROSS A SOURCE OF ELECTRIC POTENTIAL, THE KIT COMPRISING (A) A TRANSISTOR, (B) MEANS FOR CONNECTING THE TRANSISTOR COLLECTOR TO THE IGNITION PRIMARY COIL, (C) BASE BIAS VOLTAGE RESISTANCE MEANS CONNECTED TO THE TRANSISTOR BASE, (D) MEANS FOR CONNECTING THE BASE BIAS VOLTAGE RESISTANCE MEANS TO ONE TERMINAL OF THE SOURCE OF ELECTRIC POTENTIAL, (E) EMITTER CURRENT LIMITING RESISTANCE MEANS CONNECTED TO THE TRANSISTOR EMITTER, (F) MEANS FOR CONNECTING THE EMITTER CURRENT LIMITING RESISTANCE MEANS TO THE OTHER TERMINAL OF THE SOURCE OF ELECTRIC POTENTIAL, (G) BIAS VOLTAGE SOURCE MEANS CONNECTED ACROSS THE SERIES ARRANGEMENT OF THE EMITTER CURRENT LIMITING RESISTANCE MEANS AND THE EMITTER-BASE JUNCTION OF THE TRANSISTOR FOR PROVIDING SUBSTANTIALLY CONSTANT BIAS VOLTAGE ACROSS SAID SERIES ARRANGEMENT AND SUBSTANTIALLY CONSTANT CURRENT THROUGH THE EMITTER-COLLECTOR CIRCUIT, AND (H) CAPACITANCE MEANS CONNECTED IN THE TRANSISTOR CIRCUIT OPERATIVELY TO SHUNT THE SERIES ARRANGEMENT OF THE IGNITION PRIMARY COIL AND IGNITION CAPACITOR FOR PROVIDING A LOW REACTANCE DISCHARGE PATH FOR THE DISCHARGE OSCILLATIONS OF SAID SERIES ARRANGEMENT.
