Abstract: The present invention relates to a portable information sign device. In one embodiment of the invention, a top plate comprises a foundation and three plate coupling ports. A center arm comprises an arm rod axially coupled to the top plate foundation. A sliding plate is slideably coupled to the arm rod and comprises a sliding plate foundation and three sliding plate coupling ports. A spring encircling the arm rod is connected on a first end to the sliding plate foundation and on a second end to a stop coupled to the distal end of the arm rod. Three guide arms are connected to the coupling ports of the sliding plate foundation. Three legs are connected on one end to the coupling ports in the top plate and on the leg end to coupling ports on the guide arms.

Abstract: A mechanical release system and method for eliminating scale conditions in water are described. The mechanical release system may include a pressure vessel comprising a head that has a through hole extending from an inlet to an outlet on opposite sides of the head, the through hole divided by at least a circumferential partial rib into an inlet section and an outlet section. Implementations may work without restricting water flow or “water-starving” equipment and control water before it enters equipment and create a scale-eliminating environment within water for extended periods of time (e.g., up to six months or more).
