Abstract: A ribbon port burner for a gas range comprises a base defining a gas inlet portion and a gas plenum portion. The gas plenum is defined by a bottom wall portion which terminates at its outer periphery in generally vertical outer side walls. The burner also includes a cap which is positioned in fixed spaced relation to the bottom wall such that the cap forms an upper wall of gas plenum portion. In this position the cap's relation to the side walls defines a ribbon port of essentially constant cross-sectional area continuously around the periphery of the burner. The burner also includes an ignition port in the bottom wall for accommodating insertion of an ignition system within the plenum. Preferably, a gas ignition portion is defined within the gas plenum portion defining a segregated volume. The burner side walls terminate in an acutely angled surface, as does the outer portion of the lower surface of the cap, such that an essentially constant cross sectional area is maintained to form the ribbon port.

Abstract: Liquid crystals compositions, i.e. cholesteric liquid crystals or various types of liquid crystal polymers designed to turn red at or above a specified temperature and remain red at or above that temperature and that are shaped in the outline of the word "HOT" (or for cooktop stoves of a ring surrounding the heating element that may be interrupted by such an outline) are embedded on the top surface of the heating element of stoves or on the window surface of wall ovens and toaster ovens so that they glow red and instantly alert anyone that the heat element of the stove or the window is too hot to touch. For use on electric stoves including small mobile electric stoves called hot plates, the device is an improved electric coil whose central recessed area contains liquid crystals. For use on smooth cooktop stoves, including small mobile cooktop stoves called warming trays, the liquid crystal display is embedded in a top surface of the smooth area of glass or metal that forms the heating element of the stove.

Abstract: This application is an invention relating to an improvement in a gas burner for a stove for leading a mixed gas to flame holes, and burning the gas therein, through a gas passage (18) from a mixing tube (5) which produces the mixed gas by mixing a gas introduced in a jet from a nozzle and primary air drawn in with introduction of the gas. A sub-chamber (Ca) is provided separately from the gas passage for storing the mixed gas in a state of flux. The sub-chamber (Ca) communicates with the gas passage (18) through an inlet (3), and discharges the mixed gas stored therein through outlets (2) disposed adjacent the flame holes. With this construction, even when a continued combustion in the flame holes becomes difficult due to air-rich air resulting from an operation of an adjusting lever of the gas burner for a stove to adjusts the quantity of gas rapidly from large to small, the mixed gas stored in the sub-chamber (Ca) is discharged from the outlets (2) to continue the combustion.

Abstract: An atmospheric gas burner produces improved flame stability by establishing a higher pressure drop pilot flame at at least one burner port. The burner has a preferably recessed pilot port which is isolated from the primary burner ports. A small portion of the total fuel introduced to the burner is directly fed to the pilot port without entrained air.

Abstract: This invention relates to a gas burner which employs a two stage flame stabilizer. At low input rates, a fully aerated flame is stabilized at the surface of a porous material. At higher input rates, the flame blows off and is held by flame stabilization tabs. Such structures of this type, generally, operate over a very wide range of input rates and employ a highly aerated flame which reduces the flame temperature, slows NOx production, and increases the overall reaction rate by shortening the flame while reducing carbon monoxide (CO) caused by flame impingement.

Abstract: Various representative commercial cooking devices are disclosed wherein a recirculating flow of heated air, at a food cooking temperature, is created within a housing in which a horizontally disposed food support and cooking member, such as a perforated metal plate, a solid griddle plate or a metal broiling grate, is positioned. A plenum structure is utilized to convert a portion of the continuously recirculated air into a spaced series of relatively high velocity heated air impingement jets which are caused to laterally diffuse and at least slightly overlap prior to striking at least one side surface of the food support structure. In this manner, each food support structure side surface subjected to such diffused jet impingement is evenly blanketed with heating air to thereby very uniformly transfer heat from the air to the food support structure, and thus to the food supported thereby, at an accelerated rate.

Abstract: An improvement to conventional atmospheric gas burners particularly advantageously applied to the type used as surface heating units in gas cooking appliances such as ranges and cooktops, which typically comprise a burner head having a plurality of primary burner ports formed at port locations equally spaced about the periphery of the burner head. Improvement is realized by not forming primary burner ports at selected ones of the equally spaced port locations. The unused port locations are selected so as to separate the primary ports into groups. The reduction in the number of ports reduces the total port area thereby reducing the amount of primary air entrained in the air/gas mixture delivered to the burner. In addition the resulting spacing of the groups of ports has the effect of reducing the amount of secondary air per port relative to that which would be entrained by the same number of ports, if equally distributed about the periphery.
