Abstract: A system for removing snow and ice from a surface that includes a fan and a heating element contained within a hollow cavity open at one end, and a hollow duct positioned above the hollow cavity. The hollow duct is open at both ends; one end is positioned directly above the open end of the hollow cavity, while the other end leads back into the hollow cavity through a hole on the other side of the heating element contained therein. The fan blows air past the heating element and out the open end of the hollow cavity. The heated air melts any snow or ice with which it comes into contact. At least some of the heated air that does not contact any snow or ice is drawn into and through the hollow duct, and back into the hollow cavity where it may be reused.

Abstract: The filtered aromatic fireplace heat recovery system may include an intake blower that intakes air from a room; a heat exchanging means that receives and heats air from the intake blower; and an output blower that evenly distributes the heated air into a room. In some embodiments, the system may include a filter means located within the intake blower and/or the output blower that filters pollutants, particulates, offensive odors, and toxins given off by the fuel burned within the fireplace. The system may also include a fragrance dispensing means located within the intake blower and/or the output blower to distribute a desired fragrance within a room.

Abstract: An open-air filtration device cleans swimming pools and hot tubs in an efficient, reliable manner. An open-air filter with a suction chamber unit comprises two scrubbing brushes and an impeller powered by a motor drive. Water containing debris is pumped to a level above the swimming pool or hot tub surface. The debris containing water is discharged through a spout into a filter tube. A filter element associated with the filter tube, and open to atmosphere filters the debris containing water by gravitational forces solely. The spout and filter tube are, optionally, attached to a pole that manually propels the suction unit. They may alternatively be attached to a floating platform that floats on the water surface of the pool or hot tub. If filter efficiency decreases, the water level in the filter tube rises, indicating that the filter element must be replaced. A rise in water level is visually observed or detected automatically and communicated using a visible or audible alarm.

Abstract: A swimming pool cleaning apparatus that includes a housing with a substantially hollow cavity that runs along the longitudinal axis of the housing; a handle means mounted to the housing for providing directional control and movement of the housing; a wheel means movably mounted to the housing for facilitating forward, backward, and angular movement of the housing along a swimming pool surface; a debris agitator means rotatably attached to the housing to facilitate water movement through the housing and the removal of debris from the swimming pool surface; a scraping means attached to the bottom of the housing for scraping the swimming pool surface; and a debris collection means detachably connected to the housing that filters debris from pool water and that allows filtered pool water to exit from the debris collection means.
