Abstract: The invention has particular utility in connection with combustion control systems that employ lead sulfide (infrared sensitive) photoconductors in conjunction with band pass amplifiers. Flame relays in such systems would occasionally hold in after flame failure due to continued generation by the photoconductor of fluctuating signals. A flame failure transition responsive circuit is connected in series between the photoconductor and the flame relay and responds to an abrupt decrease in the flame signal to insure dropout of the flame relay.

Abstract: Fuel burner supervisory system wherein a pair of flame sensors are located close to the flame being supervised, periods of flame absence are simulated for each sensor, elements are respectively responsive to the sensors to assume a trouble state when an associated sensor indicates the absence of flame other than during a period of simulated flame absence, or when the sensor indicates the presence of flame during a period of simulated flame absence, and a flame failure alarm is connected to signal when both elements are in their trouble states, thus indicating a likely absence of flame.

Abstract: An object detecting system in which an area is monitored by a series of sequentially operated sensor channels which form a step-wise moving beam to trace out a curtain of radiation across the area, each channel including a radiation transmitter and a corresponding radiation sensor. The transmitter of each channel is permitted to receive an energizing pulse only if an output has been produced by the preceding channel; a pulse from a sensor is permitted to produce a channel output only if the transmitter of the preceding channel has received an energizing pulse. The system may be locked out if the radiation path between the transmitter and sensor of a channel is blocked by an object during operation of the channel.

Abstract: A combustion supervision system for use with a fuel burner includes two time delay devices, each of which provides a time delay as a function of current flow through the device. The first time delay device has a shorter time interval than the second time delay device. The system also includes circuitry for energizing the first and second time delay devices concurrently, circuitry for initiating an ignition sequence at the end of the timing interval provided by the first timing device, circuitry for operating a lockout device at the end of the timing interval of the second device, and circuitry responsive to the sensing of flame by a flame sensor for interrupting the timing cycle of the second timing device.

Abstract: A COMBUSTION CONTROL SYSTEM INCLUDES A FUEL CONTROL, A FLAME RELAY, AN IGNITER AND A FLAME SENSOR FOR SENSING THE PRESENCE OF FLAME IN THE COMBUSTION CHAMBER. THE CONTROL CIRCUITRY IS ARRANGED TO PERMIT FLOW OF FUEL INTO THE COMBUSTION CHAMBER IN RESPONSE TO A REQUEST FOR IGNITION AND A RESISTIVE CAPACITIVE TIMING CIRCUIT PERMITS THE FLOW OF FUEL INTO THE COMBUSTION CHAMBER FOR A PREDETERMINED TIME AND THEN TERMINATES THE FLOW OF UEL UNLESS THE FLAME SENSOR INDICATES THAT FLAME IS PRESNT BEFORE THE END OF THE PREDETERMINED TIME INTERVAL.
