  • Patent number: 8528833
    Abstract: A portable heating system used to heat a person while in cold environments. A heating unit containing a fuel combustion chamber and a heat exchanger oxidizes a fuel to produce heat. The heat from the oxidation process is transferred to the fluid using the heat exchanger. The fluid either boils or simply becomes less dense than cooler fluid in the heat exchanger and thus more buoyant. Convection moves the heated fluid upwards in to a thin bladder encapsulating the fluid and held against a person. The elevated kinetic energy in the bladder creates an entropy differential to the person. This differential allows the kinetic energy in the bladder to flow to the person thus warming them. The fluid now having less energy, now denser, flows back down the bladder to the heating unit by gravity.

  • Patent number: 6138665
    Abstract: A portable heat generating device in which fuel vapor (e.g. methanol) and an oxygen supply (e.g. air) are uniformly released through porous tubes woven with catalyst-impregnated glass filaments into a sheet-shaped, fabric-like structure enclosed in a mylar envelope. The catalyst promotes flameless combustion of the fuel vapor and oxygen, with consequent heat release occurring uniformly over the fabric-like structure. The heat generation process is started by pumping liquid fuel and air into the porous tubes using a peristaltic pump, thereby building up hydraulic pressure within the liquid fuel portion of the microbore-tubes. The level of pressure sustained within the liquid fuel portion of the microbore-tubes is limited by a manually set variable pressure release valve. The pressure in the microbore-tubes forces the liquid fuel within the porous microbore-tubing through the pores where it is converted into a vapor state before reacting with the oxygen and catalyst to produce flameless combustion.

  • Patent number: 4691688
    Abstract: A portable heater comprising a double-wall vessel which forms a combustion chamber and encloses a suitable fuel. Air passages provide an airflow through the vessel for supporting combustion. Also included are endless conduits which entrap displaced fuel to prevent it from escaping from the heater through the air passages. Thus, fuel is prevented from escaping from the heater in all positions of the same in the event that the heater is dropped or otherwise upset. A set of cooling fins, encircling a fuel holder, cool the fuel to help maintain an even burn rate. The heater further includes an adjustable flame attenuator for selective heat control. At a low heat setting the invention may be used as a personal or close contact heater wherein an outer wall serves as a guard for preventing contact burns.

  • Patent number: 4598192
    Abstract: An electrically heated handle, particularly for fishing rods, has an elongated thermally conductive shell enclosing an interior chamber in which is located a solid body of a material having high electrical resistance, such as Steatite, defining a heater core having its entire outer surface in heat transfer engagement with the shell. An elongated electric heating coil, e.g., of Nichrome, extends longitudinally through the interior of the heater core and is connected to an external power source through a switch and power supply conductors extending through the rear end portion of the handle. The front end portion of the handle is formed with an elongated socket chamber thermally insulated from the interior chamber and adapted to receive and fit over the butt end of a fishing rod. Once the heater core of the handle is initially heated, the heat is stored for slow dissipation to the handle and hand of the holder, requiring infrequent replenishing of electric current to the electric heating coil.

  • Patent number: 4294225
    Abstract: High-pressure air from the air supply is admitted into the heater system through a pressure regulator. Fuel, such as propane, enters the system from a fuel canister. The air and fuel of controlled volumes mix and flow together into a catalytic combustion chamber where combustion is initiated by a spark generator. The heat of combustion is caused to pass through the walls of the combustion chamber, then through thermoelectric modules, converting part of the heat to electricity. The remaining and larger part of the heat passes to a heat exchanger on the opposite side of the thermoelectric module. Circulating water passes through the heat-exchanging chamber, absorbs the heat produced by the combustion reaction and is further pumped to the diver's suit. The electricity generated by the thermoelectric modules is used to power an electric motor driving a circulating pump.

  • Patent number: 4167932
    Abstract: A heater system for warming the body of a diver while underwater, to be used in combination with and powered by an air supply tank is disclosed. In essence, the heater system functions by taking in controlled amounts of water from the ambient, heating this water and delivering it to the diver's suit.High-pressure air from the air supply is admitted into the heater system through a pressure regulator which reduces the air pressure and utilizes the energy thus provided to operate as a pneumatic motor and water-circulating pump. The reduced-pressure air controls a fuel pressure regulator, allowing fuel, such as propane, to enter the system from a fuel canister. The air and fuel of controlled volume are permitted to mix and flow together into a catalytic combustion chamber where combustion is initiated by a spark generator.

  • Patent number: 4068651
    Abstract: This is a catalytic warmer or heater which may be made in different sizes and shapes. A chimney section top has an opening through which a heatable material container is insertable, and which rests on an X-frame supported on punched-in tongues providing draft apertures for the chimney, while a lower spaced series of punched-in tongues rest on a catalyst containing cage which, in turn, rests on a flange of fuel cartridge section below having a wick extending up from the cartridge to be lighted temporarily to initiate the catalytic combustion process. The supporting X-frame has a depending cylinder providing a snuffer to snuff out the wick and permit the catalytic combustion to continue. The catalytic combustion is stopped when desired by merely turning the entire heater or warmer upside down and then removing the fuel cartridge containing section, now on top, from the chimney section, now on bottom, the catalyst cage remaining with the chimney section and thus separated from the cartridge fuel section.
