The resistor 54 is also in the form of a coil of wire having required characteristics but is not exposed to the heat of any flame. This resistor 54 is adapted to become heated upon passage of electric current therethrough and will change its resistance appreciably in accordance with the ...
43 designates the primary circuit wire leading from the battery 44; 45 and 46 the primary and secondary coils of the transformer or spark coil, the secondary coil being connected by a wire 48 to the distributor arm 41. The wire 43 of the primary circuit is connected to the circuit ...
2. Ignition apparatus comprising in combination, an ignition coil including a primary winding providing a normal excitation circuit, means providing an alternative excitation circuit, a current source, a circuit interrupter for controlling the passage of current from the source through the excitation circ...
Tube 45 has a grid 50 connected, by wire 51 with a resistance 52 in parallel with a condenser 53, both together being connected with one end of the primary 55 of an oscillator coil 54, the other end of which is connected by wire 57 with a condenser 58 connected with wire 48. An ...
The coil is primarily a magneto coil and has fewer turns of larger wire and much less resistance than the average primary of an induction coil. The coil 15 is purposely designed to produce good sparking at low engine speeds on the magneto principle of operation. While the usual primary of ...
S indicates the 'usual secondary of the spark coil supplying energy through distributor D to spark plugs 10. The ballast resistance R preferably consists of a fine wire of substantially pure iron contained in a sealed tube having an atmosphere of hydrogen. The tube may take the form shown ...
This invention relates to an electrical ignition device for use with oil burners, particularly of the class in which the oil is projected in a thin sheet or spray, the device being of the hot wire or hot element type (as distinguished from the "spark" type). Devices of the kind referred...
a wire connecting said timer insulated terminal with the ignition 1.5 coil primary winding, a timer condenser connected with the timer contact which is connected with said insulated timer terminal, a distributor including a center terminal for distributing sparking impulses generated in the secondary win...
