摘要： A control device includes a fail-safe control circuit for controlling the length of time that a gas valve is open during the ignition cycle of a gas appliance. The control circuit includes a capacitor (11) arranged to charge to a predetermined voltage. During the timing cycle the capacitor is arranged to discharge through the coil (5) of a solenoid shut-off valve.

摘要： Apparatus and methods are described for the detection of the presence of a flame (10), the apparatus including circuit means for applying an alternating voltage to a flame probe (2) such that the alternating voltage is partially rectified in the presence of a flame (10) at the probe (2) resulting in the development of a DC voltage component. The DC voltage component causes the accumulation of a corresponding electrical charge in a storage element (18), the apparatus includes means (120,36) for periodically releasing the charge. An optical coupling means (40) is responsive to the released charge to initiate a control signal in a control signal generator (130), the control signal indicating detection of the flame (10).
