US Patent:

43556248, Oct 26, 1982

Filed:

Mar 6, 1980

Appl. No.:

6/127783

Inventors:

James C. Hardin - Gastonia NC
Gerald D. Hardin - Gastonia NC

International Classification:

F24B 300

US Classification:

126 66

Abstract:

A forced air, fuel burning heater is provided which includes a relatively large damper plate slideably mounted immediately below the top wall of the heater, to thereby insulate the top wall from the heat of combustion and thereby reduce the temperature and thus the tendency of the top wall to warp from excessive heat. The damper plate preferably includes a rearward edge which is doubled upon itself to further insulate the edge of the flue opening in the top wall from heat, where warpage commonly occurs. The disclosed heater also includes a separate blower assembly which may be selectively mounted on either side of the combustion chamber with equally effective air circulation, and the hearth plate includes an upwardly inclined forward edge portion for reflecting radiant heat back toward the heater and thus reducing the temperature of the adjacent floor surface.

Abstract:

A nasal irrigation system for rinsing nasal and sinus passages or cavities includes a solution preparation unit and a dispensing container. The solution preparation unit includes a first water reservoir, a filter that is in fluid communication with an outlet of the first water reservoir and filters water passing therethrough, a second water reservoir that is in fluid communication with the filter, and a heating element that brings filtered water in the second water reservoir to a boil to clean the filtered water, and a filler port. The dispensing container receives a nasal rinse solution from the solution preparation unit, via the filler port, and administers the nasal rinse solution to a user via a direct nostril interface. The solution preparation unit can also include a cooling element, additive reservoirs for materials to calibrate salinity or to provide a pH buffer, and a control circuit to control operation thereof.
