  • Patent number: 9453642
    Abstract: An attachment for a torch includes a combustion cone mounted on a fuel delivery tube. The combustion cone bounds a combustion chamber and has an inlet through which fuel from the tube enters the chamber to create a flame when the torch ignites the fuel. The cone diverges away from the inlet and to an outlet to enable the flame to diverge and spread within the chamber. The chamber substantially contains the flame therein. At least one apertured radiator, and preferably, a pair of apertured radiators, is mounted in the chamber in direct contact with the flame, and heated by the flame to a temperature sufficient to cause each radiator to radiate infrared radiation through and past the outlet. A tipping-resistant holder holds a fuel canister of the torch upright when placed on a support surface.

  • Patent number: 8079302
    Abstract: Described here is a rectangular, parallelepiped shaped, portable cooking device that consists of a rigid Stand, with attached lid and flaps, that supports multiple food heating containers. A dual purpose transport case/cooking cover, made of heat resistant materials, is a key feature to the design utility by securely transporting the device and acting as a heat efficiency Cover during the food heating process. When used in conjunction with the Stand flaps and lids, this Cover provides many innovations over prior art by preventing heat escape and weather intrusion. Various burner and fuel devices (i.e.: Sterno, Propane, Electric, Coal, Wood . . . ) can be used to provide the heat for this device. The combination of these multi-functional components, in a single compact, portable, modular unit provide significant improvements over current conventional devices by offering multiple options for food heating and serving with increased efficiency in space usage, heat efficiency and transportability.

  • Patent number: 5706143
    Abstract: A magnetically actuated optical focusing device is provided. The focusing device comprises a housing with an optical component being displaceably and rotatably arranged therein. The optical component is ferromagnetically coupled, via an internal magnet arranged thereon, to an external magnet arranged outside of the housing, the external magnet being fixed to a focusing ring which is rotatably mounted on the housing. When the focusing ring is rotated, the ferromagnetic attraction between the magnets is sufficient to drive the internal magnet through a helical channel defined on the internal surface of the housing, thus causing the optical component to be longitudinally displaced within the housing. The helical channel exerts sufficient restraining force on the inner magnet so that the inner magnet remains in a particular position along the channel even if the ferromagnetic coupling between the magnets is broken down.

    Abstract: A cooker and/or radiant-heating space heater system comprises a plurality of arcuate sheet metal shell segments assembled with overlapping edge portions so as to form a substantially cylindrical inner shell surrounded by a plurality of similarly overlapping arcuate segments which may be spaced selectively relative to the inner shell and to each other so as to vary the spaces thus defined between the inner shell and the outer segments. The inner shell is spaced above a support surface such as the ground, and the outer segments rest on the support surface so that a combustion zone within the inner shell is in communication with the spaces between the inner shell and the outer segments. For highly efficient combustion, air is drawn down such spaces, due to negative pressure induced by convection over a fire within the combustion zone, and preheated through contact with the hot inner shell prior to entering the combustion zone.

A variety of secondary devices may be affixed to the basic heat generator or stove to provide for a variety of applications.

  • Patent number: 4708069
    Abstract: A heating appliance which burns solid fuel has a bottom feed to a furnace vessel, conveniently by means of an auger. The furnace vessel is arranged to be driven in rotation which assists keeping a uniformly distributed fire in the furnace vessel, and makes possible the discharge of ash overflowing from the top of the vessel through an airlock system. Preferably, a water jacket surrounds the furnace vessel and a poker is moved in the furnace vessel as it rotates. Combustion air can be blown or sucked in by a fan. The heating appliance can be a domestic cooker, also heating water for central heating.

  • Patent number: 4630592
    Abstract: The heating stove comprises from top to bottom, a smoke space, an oven, a combustion chamber and an ash-pit; a grate separates the chamber from the ash-pit. The grate comprises a plurality of open-ended hollow cylindrical metallic ducts which criss-cross so as to form a X and which open outwardly of the stove for heating ambient air circulating therethrough. Each of the ducts has a substantially-flattened crossing portion, in order to reduce the spacing between the tubes. The grate may support a solid combustible, but permit the ashes to drop into the ash-pit between the ducts. A plurality of upright semi-cylindrical tubes are fixed to the sides of the oven and form passages between the combustion chamber and the smoke space. The oven is heated not only at its bottom but along its side walls and the tubes also serve to heat the ambient air.

  • Patent number: 4425901
    Abstract: A heat exchange device is adapted to recover heat from the fire box of a wood burning stove or the like for heating ambient air in a room or other enclosed space. The heat exchange device is adapted to mount in a recess in a stove top in place of a lid which is normally supplied with the stove. The device according to the invention includes heat exchange means which extend into the fire box of the stove below the top surface thereof. The heat from the heat exchange device is transmitted into a main cavity of the device where the heat is transferred to air forced through the main cavity by a blower mounted to an outside surface of the device. Air exit means are provided on a surface opposite to the surface on which the blower is mounted to provide a passage for heated air into the room or other enclosed space to be heated. The device may also include a top mounted isolated handle for ease in handling the device such as for moving from one area to another.
