Abstract: A device for reclaiming heated air near the ceiling of a room by circulating it to the lower portions of a room which reduces thermal stratification and distributes warm room air, which, improves comfort and heating efficiency, and in cooling mode, can be turned 180 degrees in the vertical plane to move cool air from the floor to the ceiling. Suspended from the ceiling by a small hook, the lightweight double walled fabric structure provides insulation against heat loss of the moving air, and contains a quiet and efficient fan at the bottom of the inner tube assembly which directs airflow into the room through a deflector crafted from a folded fabric sheet. The inner tube is held open against the negative pressure generated by suction of the fan by external springs attached to the outer wall of the inner tube, each spring fashioned from two struts connected by a short segment of elastic polymer.

Abstract: A process and implementing apparatus are disclosed by which the curing time of a water-based adhesive is shortened as applied to the bonding of two fibrous substrates, such as paperboard or corrugated fiberboard.
