Abstract: A method and a burner for combustion in a heating furnace of a fuel with an oxidant in the form of oxygen gas, wherein fuel and oxidant are supplied to a burner head. Fuel and oxidant, respectively, are injected via the burner head through at least two pairs of nozzles, wherein one nozzle pair is defined by a separate fuel nozzle and a separate oxidant nozzle. The nozzles of the nozzle pairs are uniformly distributed over the furnace-interior-facing surface of the burner and within the circumference of the burner head. An oxidant nozzle is provided on each side of a fuel nozzle.

Abstract: A lantern which may be manipulated between a closed position in which it surrounds a mantle or mantles for the lantern to a second, opened position in which the globe has been moved or otherwise manipulated to provide access to the mantle or mantles. As an example, the globe may slide upward relative to the mantles so as to expose the mantles for changing. A globe for the lantern includes a frosted band located on a circumference radially outward from the mantle or mantles. The frosted band minimizes glare from the lantern, and the combination of the frosted band and clear sections located above and below the band provide illumination substantially equal to a clear globe.

Abstract: An incandescent gas mantle assembly includes a metal coupling member and a mantle supporting sleeve member of thermally resistant material that has a skirt portion to which a metal oxide mantle sock is secured in depending relation. The metal coupling member has a body portion of disc configuration with an outer periphery and an inner periphery, a plurality of inwardly extending first coupling portions integral with and spaced about the body portion for attachment to a cooperating burner head, and a plurality of second coupling portions integral with and spaced about the body portion, the second coupling portions being in coupling engagement with recess structure of the mantle supporting sleeve member.

Abstract: In a device for the burning of gas by means of a mantle the improvement comprises a support for the mantle. The support includes attachment means for connecting it to a gas outlet tube emanating from the device. Lower body means is connected to the attachment means which is characterized as being substantially incapable of communicating significant amounts of gas from the interior to the exterior side wall of the lower body means. Connected thereto is an upper body means which is characterized as having a substantially porous side wall for the communication of gas to its exterior. A support plate having a substantially circular configuration is connected to the upper body means and, finally, mantle piercing means is caused to emanate from the support plate.
