Abstract: A catalytic combustion burner made of porous material and a bottle equipped with such a burner have an optimized operating performance, which enables the burner to withstand and not be extinguished when it is subjected to strong air currents such as air conditioning.

Abstract: A welding apparatus is provided herein. The apparatus includes a wire source having welding wire, a wire feed drive, and a wire pulser. The wire feed drive drives the welding wire from the wire source. The wire pulser has a first end associated with the wire feed drive and a second end associated with a wire conduit. The wire is fed through the wire conduit to a wire nozzle. The wire pulser increase and decrease the effective length of the wire as the wire moves through the wire conduit from the wire feed drive to the wire nozzle.

Abstract: A catalytic burner is provided. The method of using the catalytic burner utilizes flameless combustion. The absence of a flame results in a more even temperature distribution throughout the length of the burner. The invention lowers the autoignition temperature by placing a catalytic surface within the burner and offers relatively even distribution of heat from the burner. Thus, the amount and location of the combustion reaction can be controlled by varying the amount and distribution of catalyst within the burner.

Abstract: A portable, handheld lighter assembly for lighting a lighting end of a rolled tobacco product, such as a cigarette or a cigar, includes an elongated body formed with opposed first and second channels formed on either side of a combustion zone and a stop formed in the elongated body. The combustion zone traverses the stop so as to couple the first channel in gaseous communication with the second channel. The stop restricts movement of a rolled tobacco product into the second channel from the first channel and restricts movement of a rolled tobacco product into the first channel from the second channel. A lighter is coupled to the elongated body and is for applying lighting heat to the combustion zone at the stop for lighting a lighting end of a rolled tobacco product applied against the stop in the combustion zone from the first channel or the second channel.

Abstract: Apparatus is described for combusting exhaust gases output from a plurality of process chambers. The apparatus comprises a plurality of exhaust gas combustion nozzles (22) connected to a combustion chamber (24). Each nozzle receives a respective exhaust gas (26), and comprises means for receiving a fuel (40) and an oxidant (30) for use in forming a combustion flame within the chamber. A controller receives data indicative of the chemistry of the exhaust gas supplied to each nozzle, and adjusts the relative amounts of fuel and oxidant supplied to each nozzle in response to the received data. This can enable the nature of each combustion flame to be selectively modified according to the nature of the exhaust gases to be destroyed by that flame, thereby enhancing the destruction rate efficiency of the exhaust gas and optimising fuel consumption.

Abstract: A device for warming a shoe is disclosed. An insole has a top cavity. A releasable shoe pad includes a top padding member and a recess between forward and rearward bottom portions. The device includes a thin metal member formed on the pad and including an intermediate conductive member, a forward conductive section extended from the conductive member, and a rearward conductive section extended from the conductive member, and a heater unit fastened in a space defined by the recess. The heater unit includes a fuel chamber, a combustion chamber filled with zirconia fibers, and a channel interconnected the fuel and the combustion chambers, the channel including fibers and a wick having one end immersed in the fuel chamber and the other end connected to the fibers.

Abstract: A grill that includes a base and, residing thereupon, a cooking surface in the form of a grate for supporting food to be cooked by the grill. A first removable drawer is positionable beneath the grate having at least one burner. A source of combustible fuel, such as a pressurized gas, is contained within a tank located within the base of the grill. A fuel line emanating from the pressurized tank terminates at a control valve having a first gas transmitting position facilitating the combustible fuel fed to the at least one burner and a second gas blocking position preventing the combustible fuel to be fed to the at least one burner. The control valve is capable of assuming the first gas transmitting position only if the first removable drawer has been fully positioned beneath the cooking surface. When an alternative drawer, such as one containing charcoal is employed, fuel from the pressurized tank is blocked from emanating from the tank.

Abstract: A catalyzer for burning part of a gaseous fuel/oxidant mixture, in particular for a burner of a power plant installation, has catalytically active channels and catalytically inactive channels and at least two sectors are arranged consecutively in the main flow direction. The sectors include a first sector defining an inlet sector and at least one following sector that includes one or more of a mixing sector arranged downstream from the inlet sector and an outlet sector. Further, the catalyzer has one or more of a smaller flow resistance in the inlet sector than any following sector, a higher catalytic activity in the inlet sector than any following sector, a plurality of holes in the mixing sector oriented transversely to the main flow direction and through which adjoining channels communicate, and a swirl generator in the outlet sector that provides a swirl to a gas mixture flowing through the outlet sector.

Abstract: Described is a premix burner arrangement with catalytic combustion for operating a combustion chamber of a gas turbine arrangement, as well as a method to this effect, having a premix burner, wherein at least one fuel addition unit as well as inlet air openings have been provided in such a way that gaseous and/or liquid fuel can be mixed with combustion inlet air inside the premix burner and form a fuel/air mixture, which exits from the premix burner downstream in the direction towards the combustion chamber positioned after the premix burner arrangement and which can be ignited inside the combustion chamber.

Abstract: A gas control assembly (1) for controlling supply of fuel gas to a gas burner. The assembly (1) includes a housing (2) has an elongate body (3) with a longitudinally extending gas flow passage (4), an inlet (5) into the passage (4) for gas communication with a manifold, and an outlet (7) from the passage (4) for directing a regulated flow of gas from the manifold to the burner. A safety valve (10) is mounted in a valve chamber (9), within the gas flow passage (4), and is operable to control flow of gas through the gas flow passage from the inlet (5) toward the outlet (7). An actuating member (18) is mounted in the passage (4) for guided movement along the passage (4) to operate the valve (10). A regulator valve (38) is mounted in a further valve chamber (37) in the body (3) and is operable to regulate flow of gas to the outlet (7). The regulator valve (38) lies in a plane containing the longitudinal axis of the gas flow passage (4).

Abstract: A catalytic burner has a nozzle for forming a jet of combustible gas extending along a jet axis, a catalyst body supported offset from and immediately adjacent the axis heatable to an activation temperature at which it supports catalytic combustion, and a device like a piezoelectric crystal for igniting the jet and thereby forming at the axis a flame that heats the body. The flame is quenched after it has heated the body to its activation temperature.

Abstract: When a cap of a cigarette lighter is opened, fuel is mixed in a gasified state with externally drawn air, and the resultant mixture of air and gasified fuel is supplied to a catalyst within the lighter body for causing natural combustion of the mixture by the oxidizing action to elevate the temperature of the air-fuel mixture to the ignition point so as to bring about ignition.
