Abstract: A system and method for providing high power factor wired lamp control that include receiving a lighting control input though a switch that is associated with at least one of: an operation and a function of at least one lamp. The system and method also include processing a digital data packet that includes at least one electronic data command associated with the lighting control input. The system and method additionally include implementing at least one powerline interruption associated with an AC power cycle to communicate the digital data packet to the at least one lamp. The system and method further include controlling the at least one lamp to operate based on the lighting control input based on the receipt of the digital data packet communicated through the AC power cycle.

Abstract: A large sedimentation tank having a traction-driven composite sludge raking mechanism provided with lift capability, and comprising a rotary traction-driven drive arm of girder-like construction exposed above the liquid level, and draft-connected to an inner load yielding self-liftable rake arm operating in the central sludge accumulation zone in the tank, and also connected to an outer complementary rake structure operating in an outer annular zone to move sludge therefrom into the central accumulation zone.
