Abstract: A device for intensifying a flame, comprising an object intended to be placed in front of the burner head, at a distance from said burner head, so that it is placed at least partly inside a flame extending from the burner head, and furthermore, said object being arranged to glow, heated by said flame. An apparatus for applying the device, for heating a liquid or air, comprising a burner and a combustion chamber, wherein the apparatus comprises an object in the combustion chamber. In the method, the device is installed in front of the burner head, or in an apparatus for heating a liquid or air, comprising an opening for the burner head, and a combustion chamber.

Abstract: A lantern and fuel system with a safety cover, the safety cover having a round disc-like configuration, a plurality of radially spaced discontinuities of various sizes provided through the cover, the safety cover having a diameter sized to fit securely within the second diameter of a lower skirt, and a Z-shaped upward projection coupled to the cover with the projection having a notch at an uncoupled end.

Abstract: A lantern and fuel system with a pump subassembly. The pump subassembly includes a beveled seat having an interior end with a cylindrical configuration constituting an interior guard with a first O-ring on the seat adjacent to the interior guard. The beveled seat has an exterior end with a cylindrical configuration constituting an exterior guard with a second O-ring on the seats adjacent to the exterior guard. The beveled seat has an intermediate guard on the seat between the first O-ring and the second O-ring.

Abstract: A pressure gauge subassembly, a pump subassembly, a lower skirt and cap, and an ignition bowl having an up-pipe are coupled to a fuel tank. A safety cover has a Z-shaped upward projection coupled to the lower skirt. A heat resistant glass chimney is coupled to the lower and upper skirts. A lower skirt is coupled to the glass chimney. A lantern top cap with a mixing chamber is coupled to the upper skirt. A plurality of connecting rods firmly hold and contain the glass chimney between the upper skirt and the lower skirt. A vaporizer has two warming coils and a nipple. A quantity of steel wool is wrapped around a vaporizer shaft. A J-shaped mixing tube having a wire mesh and a baffle plate is coupled to the lantern top cap. A mantel is coupled to the mixing tube. The fuel is a quantity of liquid methanol.

Abstract: A cup is provided adjacent the generator tube of a kerosene lantern for holding a measured amount of fuel. A wick is located in the cup for burning the fuel at a controlled rate. A foraminous housing extends around and above the wick to control the entrainment of air with the fuel from the wick during burning and to direct the resulting flame against the generator tube thereby preheating fuel in the generator tube to its vaporization temperature until the heat of combustion of fuel at the mantle causes the vaporization of fuel in the generator to be self-sustaining.
