Abstract: An electrical load controller circuit for controlling power consumption is described. A detection circuit detects the current flowing through a supply line and produces an output signal representative thereof. A comparator circuit compares the output signal with an adjustable reference signal which is indicative of the maximum power to be consumed by loads connected to the supply line. All of the loads are connected to switching circuits, and these are enabled and disabled by signals received from a decade counter which is in turn controlled by inverters and timer circuits whereby loads can be placed in service in a sequential manner. A modulator intermittently controls the time periods that the electrical load is connected to the supply line as well as the ON and OFF periods of the loads for daytime or nighttime operation.

Abstract: The disclosure describes a system for spraying an insecticide or the like, automatically and for a given period of time. The system includes a spray applicator mounted on a rotary table so as to direct a spray of insecticide all around the axis of the rotary table upon rotation of the latter. The rotary table includes a housing with a rotatable base, which is fixed at the top, a shaft extending in the housing and maintained fixed with respect to the housing. The base should be rotatable with respect to the housing. A rotatable sleeve is mounted at the bottom of the fixed shaft and is operatively connected to the rotatable base. A gear arrangement which is motor operated causes rotation of the sleeve and thereby rotates the base. An insecticide which is preferably mixed continuously is continuously fed to the spray applicator.
