Abstract: The window for a hot chamber sealed off from the surroundings includes a multi-pane module. The multi-pane module has at least two transparent panes (1, 2) held apart by peripheral spacers (3) and interconnected with the peripheral spacers (3) in a gas-tight fashion so that the transparent panes and spacers bound an interior space (9). The peripheral spacers (3) are provided with at least one through-going opening (5), each of which is closed with a replaceable, permeable filter pad (6). This permeable filter pad (6) permits gases to penetrate the filter pad (6) for gas exchange in order to prevent pressure build up in the interior space between the panes and spacers, but prevents water vapor and other vapors containing grease, oil and other contaminating particles from entering the interior space.

Abstract: A combustion apparatus which has a post combustion hot gas fan and a recirculation duct positioned down stream from the fan to reduce NOx emissions by returning a portion of the exhaust from the combustion zone back to the combustion zone. For example, in one embodiment the increased velocity of the exhaust gas stream from the post combustion hot gas fan which is required to overcome the pressure drop in a post combustion treatment unit is used as the motive force for the recirculation of a portion of the exhaust to the combustion zone to reduce the NOx exiting the apparatus to a level below that of the post combustion treatment alone.

The leg assemblies may fold for storage and unfold to raise the stove to a low- or high-profile. In a collapsed position, the stove and its self-contained components resemble a rectangular suitcase. The stove may be expanded from the collapsed position to several possible configurations, optionally having high- or low-profiles, exposed and/or covered burners, side tables, a hoist assembly, and a middle shelf or a middle table.

Abstract: A piezoelectric jet lighter is adapted for producing both jet flame and visible in order to selectively light a cigarette, a cigar, and a pipe. The piezoelectric jet lighter includes a gas ejecting pipe having a gas releasable valve connected to a jet nozzle for producing the jet flame and two gas emitting nozzles for producing the visible flames respectively. To operate the piezoelectric lighter, a downward force must be applied on an ignition button to ignite the lighter wherein the gas is emitted from the gas ejecting pipe to the jet flame to produce the jet flame. While the downward force is released, the gas releasable valve is automatically switched for allowing gas transported to the gas emitting nozzles to produce the visible flame.

Abstract: A vaporization module is provided that includes a capillary member to convert non-pressurized liquid to pressurized vapor. The pressure is sustained by capillary pressure of the liquid in the capillary member. The capillary member has low thermal conductivity and small-sized pores that permits liquid to travel by capillary action toward the vaporization zone. Often, the pores of the capillary member are substantially uniform in size. The capillary member may comprise ceramic material. The module also includes an orifice plate that has one or more orifices to permit release of pressurized vapor, e.g. as a pressurized vapor jet. The orifice plate is associated with a sealing member to form an at least partial enclosure of the module so that vapor may accumulate and pressure may be increased within the module. In addition, other aspects of the present invention relating to the vaporization and pressurization of liquid are described.

Abstract: The invention relates to a control means for gas burners. Control means for gas burners are used for supplying a gas flow and a combustion air flow to a burner. In this procedure, the gas flow is adjustable in dependence on the combustion air pressure. In the case of known control means, pressure measurement is effected by means of a diaphragm, i.e. pneumatically. This pneumatic pressure measurement restricts the scope of application of known control means. In the case of the control means according to the invention, there is provided a sensor (16) which generates an electric or electronic signal 19 which is used for adjusting the gas valve 11 (FIG. 1).

Abstract: A heat shielding assembly, preferably for a downdraft cooking system including a fan motor mounted outside a plenum located below a cooktop for generating an air flow designed to remove air laden cooking byproducts from a cooking zone, prevents direct contact with laminations of the motor which become heated during use of the fan. The heat shielding assembly preferably takes the form of a plastic sleeve which encircles a housing portion of the motor. Therefore, the sleeve is designed to protect a consumer, maintenance personnel or the like from direct contact with motor housing portions which have become hot during operation of the downdraft system when an area below the cooktop is accessed.

Abstract: A gas-fired, infrared, food warmer having a gas-fired, infrared, burner adjustably mounted above a surface for supporting food. A reflector encloses the burner and is open at the bottom to expose the food supporting surface to the infrared heat directly from the burner and indirectly from the reflector. A heat shield surrounds the top, sides and ends of the reflector in spaced relation and a perforated protective cover surrounds the top, sides and ends of the heat shield in spaced relation thereto. A gas canister is exchangeably mounted in a housing on the warmer for portability therewith in supplying gas to the burner.

Abstract: Presented is an improved insulation device which, in multiple numbers, forms a swimming pool cover, or cover for other types of liquid containers. A complete cover is formed of multiple independent floatation insulation devices that collectively cover the entire surface of the water or liquid on which they float, yet enable dispersion thereof as a safety feature from below the surface of the water or liquid by a person in the water so that the person may extend his or her head through the cover to breath air. Structurally, the insulation device is hexagonal so as to cooperatively abut adjacent insulation devices to form a complete cover. The insulation device is injection molded-from plastic in two mirror image half-shells each of which is formed with a circular recess centrally disposed within the hexagonal outer periphery.
