  • Patent number: 7063527
    Abstract: A ceramic burner plaque is described being of a predetermined thickness defined between first and second planar surfaces and through which a plurality of burner ports (6) pass from one surface to the other. The ports are arranged in offset rows and a plurality of polygonal channels (10) are cut into the second surface (8) of the plaque, said channels also being arranged in offset fashion rows and being of a depth less than the thickness of the plaque. The channels are ideally octogonal in shape and of a width which widens progressively from the narrow base of the channel within the thickness of the plaque towards the second surface. The width of the channels at their base is ideally similar or marginally greater to the dimensions of the burner ports and the shape and position of the channels is such that a plurality of burner ports are coincidental with the base thereof.

  • Patent number: 7021927
    Abstract: A candle stand for holding and displaying a plurality of candles. The candle stand includes vertical rods that form a rigid tripod structure by attaching at the upper ends of the rods via washers, a pivoting, threaded attachment mechanism, and a threaded handle. The rods support horizontal rings that are provided with individual candle holders. The rods are provided with hooks spaced at intervals. The rings are provided with sets of projecting fingers that form channels. To attach the rings to the rods, the hooks are inserted into the corresponding channels on the rings. This forms an attractive, three-dimensional structure that is sufficiently rigid so as to hold a plurality of candles safely, yet is easily disassembled and collapsed into essentially flat components for easy shipping or storage.

  • Patent number: 6923174
    Abstract: A solar installation is described. It has a solar element and a diffractively and/or refractively operating optical apparatus by way of which the incident sunlight is passed directedly perpendicularly on to the solar element. The optical apparatus is caused to track the position of the sun by way of a tracking device. The optical apparatus uses a light-deflecting foil having portions of different natures with a structure having a different optical action. By virtue of the action of the tracking device the holographic foil is moved relative to the solar element so that different portions of the foil move into an operative position above the solar element in succession during the tracking procedure.

  • Patent number: 6904903
    Abstract: A convection steam cooking device utilizes forced recirculation of gases along a primary recirculation path that extends through a steam chamber so that gases from the cooking cavity flow through the steam chamber and are subjected to a “steam bath” that alters the gases by adding heat and/or moisture. The cooking device includes a cooking cavity, a fan, a steam chamber disposed beneath the cooking cavity with a lower pool area for holding water and an upper steam collecting area disposed directly above the pool area, and a removable baffle disposed between the cooking cavity and the steam chamber with a perforated section remote from the fan and disposed at an upward angle. The primary forced recirculation path extends from the main cooking cavity, through the baffle, substantially across the steam collecting area, through a duct to the fan, and back to the main cavity.

  • Patent number: 6896511
    Abstract: A process for adding objects to a candle. Methods are disclosed for adding an object before the fuel has assumed its final state and after the fuel has assumed its final state. Several related approaches for introducing the object are disclosed, including making an incision to insert the object, retracting the fuel away from its container in order to slip the object in between the fuel and the container, and creating a melted region in the fuel which will allow the object's insertion. Once the object is in place, the fuel is locally heated above its melting temperature in order to reflow the fuel around the object. The candle is then cooled so that the fuel transitions back into its normal state.

  • Patent number: 6890173
    Abstract: The invention relates to a pocket lighter of the type that comprises a fuel container (1), a valve (2), which regulates the opening and closing of said container, a pyrophoric flint (6), a revolving toothed wheel (8), which can produce sparks that are directed towards the valve (2), spring means (7), which exert a force that applies the flint against the toothed wheel, and two disks (10) having end journals (12) that move in respective housings (13). The inventive lighter is characterised in that, in addition to acting as the force transmission element between the finger and the wheel (8), the disks (10) also serve as a rotor for a braking device in which the stator is formed by an element (15) that rubs against said rotor. More specifically, the stator of the braking device comprises a spring (15) which acts on a smooth surface of the rotor (10) in a radial or tangential direction. The spring (15) may form part of the actual structure of the button (14) or it may be independent of said button.

  • Patent number: 6880547
    Abstract: A swimming pool heater that heats a private swimming pool and can be used to provide heating for a house, a cottage or a commercial swimming pool. Wood, that is often found around pools, is used as primary fuel. This oven has a cylindrical external appearance and is disposed horizontally. It is made of an interior wall and an exterior wall in between which water circulates. The interior wall plays the role of fire chamber and heat exchanger; the section having the shape of an annular zig-zag offers more surface for heat exchange than a simple cylinder thus increasing the overall heater efficiency. The left-over ashes insulate the bottom of the heating chamber replacing often used tiles. For general use, logs and branches are used as fuel, and an increase of 20 to 30 degrees F. of the water of a typical garden pool is attained overnight.

  • Patent number: 6880548
    Abstract: A warm air furnace system has a valve for controlling the flow of fuel, and a mixing component for receiving fuel from the valve and mixing the fuel with air to form an air-fuel premix. The warm air furnace system also has a burner assembly for receiving the air-fuel premix from the mixer, and an inducer for pulling the air-fuel premix through the burner assembly. The air-fuel premix drawn from the burner assembly is ignited into a flame by an ignition element. The flame transfers heat to a heat exchanger in communication with and positioned between the burner assembly and the inducer. The heat exchanger, in turn, transfers heat to air being passed over the heat exchanger by a circulation fan. The heated air passed over the heat exchanger then provides heat to a user of the furnace.
