Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
In an ignition system for an internal combustion engine where there is a source of electrical energy and a distributor comprising: step-up transformer means having primary and secondary windings, said distributor connected to one end of said secondary winding; a first diode; a first capacitor connected in parallel with said first diode and the combination connected between one end of said primary winding and one side of said source of electrical energy; a second capacitor connected between the second end of said primary winding and ground; a pair of breaker points connected between the second end Of said primary winding and ground, the second side of said source of electrical energy connected to ground, said second end of said secondary winding connected to the second end of said primary winding, a second diode connected between the second end of said secondary winding and ground, and a fourth capacitor connected in parallel with said second diode.
Claim 2
Dependent Claim
155 words
In an ignition system for an internal combustion engine where there is a source of electrical energy and a distributor comprising: step-up transformer means having primary and secondary windings, said distributor connected to one end of said secondary winding; a first diode; a first capacitor connected in parallel with said first diode and the combination connected between one end of said primary winding and one side of said source of electrical energy; a second capacitor connected between the second end of said primary winding and ground; a pair of breaker points connected between the second end Of said primary winding and ground, the second side of said source of electrical energy connected to ground, said second end of said secondary winding connected to the second end of said primary winding, a second diode connected between the second end of said secondary winding and ground, and a fourth capacitor connected in parallel with said second diode.
Claim 3
Dependent Claim
150 words
In an ignition system for an internal combustion engine where there is a source of electrical energy and a distributor comprising: step-up transformer means having primary and secondary windings, said distributor connected to one end of said secondary winding; a first diode; a first capacitor connected in parallel with said first diode and the combination connected between one end of said primary winding and one side of said source of electrical energy; a second capacitor connected between the second end of said primary winding and ground; a pair of breaker points connected between the second end of said primary winding and ground, said one side of said source of electrical energy connected to ground and the second side to said breaker points, a second diode connected between said breaker points and the second end of said primary winding, and a third capacitor is connected in parallel with said second diode.
