Abstract: A very high efficiency internally heated steam generation system and heat exchanger are disclosed, wherein a generally rectangular housing includes end and side walls and top and bottom walls, each containing a series of small-diameter interconnected serpentine tube coil sets. A heating chamber is located at the bottom portion and at the front of the container and includes a source of fuel to generate heat within the chamber. A source of water enters the container where it is heated and passes sequentially through the several coil sets where it is heated and changes phase into steam which then passes into one or more steam tanks where it is stored and extracted when needed for a variety of uses.

Abstract: A very high efficiency steam producing heater and boiler is disclosed wherein an outer vault encases an inner casing with a small exhaust passage there between. The walls of the casing contain a series of capillary tubes through which water flows. A combustion chamber in the lower portion of the casing provides a source of heat for the water which flows from the casing into a series of water drums located near the combustion chamber. From the water tubes, the heated water then passes through a serpentine series of steam tubes and then upward into one or more steam drums. Steam passes through the steam drums out of the casing and vault for commercial or residential usage.

Abstract: A dispenser having a housing containing an aerosol spray can installed with its internal filling nozzle in a downward position. Activating a trigger will apply pressure to the bottom end of the can, and will press the can against a stop hole causing a deodorant spray to be released from the can and sprayed from a spray head into a toilet bowl.A swing away cover allows for drop-in loading of a replacement can as required. The dispenser mounts on either side of a toilet tank with an optional toilet tissue holder to hold a spare roll of toilet tissue.
