Timing circuit with means for selectively alternating the timing pulses

Claim 1

IN COMBINATION WITH A FIRST AND SECOND LOAD TO BE SEQUENCED AND AN ALTERNATING CURRENT POWER SUPPLY HAVING A FIRST PEAK OUTPUT VOLTAGE CONDUCTOR AND A SECOND PEAK OUTPUT VOLTAGE CONDUCTOR, A TIMLER COMPRISING A FIRST CONTACT CONNECTED TO SAID FIRST VOLTAGE CONDUCTOR AND SECOND, THIRD AND FOURTH CONTACTS CONNECTED TO SAID SECOND VOLTAGE CONDUCTOR, SAID FIRST AND SECOND LOAD BEING ENERGIZED RESPECTIVELY THROUGH SAID THIRD AND FOURTH CONTACTS, FIRST, AND SECOND AND THIRD SWITCH MEANS FOR SEQUENTIALLY ELECTRICALLY ENGAGING SAID CONTACTS, SAID FIRST SWITCH MEANS ENGAGEABLE WITH SAID FIRST OR SECOND CONTACT, SAID SECOND SWITCH MEANS CONNECTEAD TO ONE SIDE OF SAID FIRST LOAD AND ENGAGEABLE WITH SAID THIRD CONTACT, SAID THIRD SWITCH MEANS CONNECTED TO ONE SIDE OF SAID SECOND LOAD AND ENGAGEABLE WITH SAID FOURTH CONTACT, AND MEANS FOR MOVING SAID SWITCH MEANS INCLUDING A CAM SHAFT CONNECTED TO SAID SWITCH MEANS, MEANS FOR ROTATING SAID CAM SHAFT AND TIMING MEANS FOR INTERMITTENTLY ACTUATING SAID ROTATING MEANS, SAID TIMING MEANS INCLUDING AN ACTUATOR COIL FOR ACTUATING SAID ROTATING MEANS, A NEGATIVE RESISTANCE DIODE CONNECTED IN SERIES WITH SAID ACTUATOR COIL, SAID DIODE HAVING A PREDETERMINED SWITCHING VOLTAGE, A CAPACITOR CONNECTED IN A PARALLEL CIRCUIT WITH THE ACTUATOR COIL AND DIODE, SAID CAPACITOR BEING CAPABLE OF BEING CHARGED TO A VOLTAVE GREAT ENOUGH TO EXCEQED THE SWITCHING VOLTAGE OF SAID DIODE, A RECTIFIER CONNECTED IN SERIES WITH SAID FIRST SWITCH MEANS AND ONE SIDE OF SAID PARALLEN CIRCUIT AND ORIENTED TO PREVENT FLOW OF CURRENT THROUGH SAID DIODE BEFORE SAID DIODE REACHES ITS SWITCHING VOLTAGE, CIRCUIT MEANS CONNECTED TO THE OTHER SIDES OF SAID PARALLEL CIRCUIT AND SAID FIRST AND SECOND LOADS FOR COMPLETING A CIRCUIT WITH SAID POWER SUPPLY, SAID PEAK OUTPUT VOLTAGES OF SAID POWER SUPPLY BEING GREATER THAN THE SWITCHING VOLTAGE OF SAID DIODE FOR SELECTIVELY SUPPLYING ENERGY TO SAID RECTIFIER AND SAID PARALLEL CIRCUIT FOR REPEATEDLY OPERATING SAID ACTUATOR COIL AT ONE FREQUENCY WHEN SAID FIRST SWITCH MEANS IS ENGAGED WITH SAID FIRST CONTACT AND AT ANOTHER FREQUENCY WHEN SAID FIRST SWITCH MEANS IS ENGAGED WITH SAID SECOND CONTACT.
