ABSTRACT:
Sensors associated with a pair of weighing devices of a weight sorting system are operative through a logic circuit to effect release of loads from conveyor carriers. Lockout and reset actions produced internally of the logic circuit distinguish between sequential signals produced by the sensors and a single signal produced by one of the sensors during any monitoring cycle, to effect release of the loads between upper and lower weight limits, respectively, established by said weighing devices.
