Abstract: A burner monitoring system in which an array of burners are viewed by a video camera adapted to produce a video signal representing the infrared image of the burner array. The video processing electronics processes the video signal to determine which of the burners is lit and which of the burners is unlit by the presence or absence of hot spots in the infrared image. The video processing electronics generates a video signal which is applied to a cathode ray tube device to generate a visual indication for each of the burners indicating the lit or unlit condition of each of the burners.

Abstract: A seat and cover assembly for a toilet bowl including a seat member and a cover member pivotally mounted to a mounting block for movement relative to the bowl between an upright position and a lowered position. Springs are provided for biasing the seat member and the cover member into an abutting relationship in both the upright and lower positions of the members, and a magnetic latch assembly quick-releasably secures the cover member in its upright position.

Abstract: In an industrial control system, a plurality of remote data processing units communicate with one another over a communications link. Some of the processing units called primary remotes have inputs and outputs and control a process operation in response to signals received on the inputs by signals transmitted over the outputs. One or more of the remote processing units, referred to as a redundant remote, monitors a plurality of the other primary remotes to determine whether any of the monitored primary remotes has failed. If any of the primary remotes fails, the redundant remote takes over operation of the process controlled by the failed primary remote by sending instructions and commands over the communications link interconnecting the primary and redundant remotes.

Abstract: A system is provided for measuring the level of bulk material in a silo utilizing load cells responsive for determining total load. The silo is constructed with a separated upper storage portion and lower hopper portion with a flexible connecting seal so that the response of the load cells is independent of the weight of the storage section. The interior surfaces of the silo may be coated with an anti-friction material, such as material sold under the Registered Trademark TEFLON, and the silo surfaces have walls tapering outwardly towards the seal so as to reduce the possibility of bridging and jamming of the stored bulk material.
