Abstract: An apparatus, method, and system for highway signs, particularly those related to highway or route number and direction information related to that highway or route number. The apparatus includes a highway or route number on the sign. A high visibility portion is physically positioned relative to the route number in a manner correlated to a cardinal point compass direction relative to the route number. By this relationship, a driver will immediately perceive directional information related to the route number by the position of the portion on the sign.

Abstract: A controlled flow heat extraction and recovery apparatus using waste heat from a cooling system to heat water to be held in at least one heated water storage tank thereby providing heated water having a purposeful end-use, increasing cooling efficiencies in a cooling system and heating efficiencies in a hot water heating system.

Abstract: A break-away tank tee fitting for connecting a well water storage tank to the supply or service line. The tank tee fitting has a unique disconnect arrangement for connecting the service line to either a bottom or side inlet tank. This arrangement allows the tank to be removed and replaced without cutting any pipes or wires. The tank tee fitting also provides a unique arrangement designed to easily accommodate in less space the pump switch and pressure gauge normally found in systems where the fitting is used.
