    摘要： A combustion safety arrangement in which a switch is connected in an electrical power circuit for an electromagnetic valve in a fuel passage. A combustion detecting element responds to a change of a flame caused by incomplete combustion or the like, and generates a signal or change in an electrical characteristic. The switch and the combustion detecting element are interconnected through a control circuit which has a level detector for detecting a predetermined level of the change in electrical characteristics. The arrangement is such that the switch may be opened by the predetermined level of the change in electrical characteristics. The control circuit has a time limit operation circuit so that only when the generation of the change in electrical characteristic is continued for a delayed time set by that time limit operation circuit, the switch may be opened. A timer circuit included in the control circuit is provided with a condenser which is charged through a resistance by closing a power switch in the electrical power circuit.

    摘要： A fuel ignition control system including a control arrangement for operating pilot and main valves of the system the pilot valve being operated to permit a pilot flame to be established, and the main valve being operated by a pilot flame sensing circuit which includes a controlled switching device enabled in response to the charging of a capacitor to a given value to effect the operation of the main valve, the charging of the capacitor being controlled by a further controlled switching device which supplies AC current to the capacitor in the absence of a pilot flame, preventing the capacitor from charging to the given value, and which supplies DC current to the capacitor when a pilot flame is established, permitting the capacitor to charge to the given value. In an embodiment wherein the main valve is energized by a relay controlled by the flame sensing circuit, the control arrangement includes an interlock arrangement which prevents start up of the system under certain failure conditions, such as welded relay contacts. In another embodiment, the system includes an igniter circuit which has a flame responsive enabling circuit which permits the igniter circuit to be enabled and disabled independently of the flame sensing circuit.
