摘要： A capacitor discharge ignition system (10) for an internal combustion engine has an ignition coil (22) with a magnetically permeable core (24) having an axially extending core bar (26), a primary winding (30) wound around the core bar, and a pair of secondary windings (32 and 34) axially spaced along the primary winding. A pair of spark plugs (42 and 44) are each energized by a respective one of the secondary windings. The output voltage rise time of each of the secondary windings is fast enough and of sufficient magnitude to cause the respective spark plug to ignite a combustible mixture. The output voltage rise time of each of the secondary windings remains fast enough and of sufficient magnitude to cause its respective spark plug to ignite the combustible mixture even if the spark plug of the other secondary winding becomes fouled and presents a low impedance. Each of the secondary windings dissipates substantially constant energy even if the spark plug of the other secondary winding becomes fouled.

摘要： A source of alternating current in a power supply and deflection system of a television receiver is coupled to a primary winding of a transformer, a relatively closely coupled secondary winding of which provides a voltage which may be rectified for providing operating voltage for another portion of the receiver such as the vertical deflection system. Yet another portion of the receiver, such as the audio section, is energized by voltage derived from a winding so disposed around the transformer as to be energized by leakage flux from the transformer for substantially reducing the effects of variations of the audio loading on the deflection systems.
