Abstract: A multiple fingered burner includes controls for continuity of gas flow and ignition throughout all of the ports peripherally positioned around the contoured wall of the burner body. A plurality of burner parts are nested together with an indexer limiting insertion to at least one predetermined alignment in order to avoid improper fit or alignment between adjacent burner parts. In addition, the peripherally positioned ports are covered by a laterally extending lip of a cap, and at least one of the parts includes recesses adjacent the laterally extending lip to provide ignitable gas flow passages along the peripheral wall of the burner that maintain continuity of ignition at adjacent burner ports.

Abstract: Systems and methods for modifying a virtual object stored within a computer. The systems and methods allow virtual object modifications that are otherwise computationally inconvenient. The virtual object is represented as a volumetric representation. A portion of the volumetric model is converted into an alternative representation. The alternative representation can be a representation having a different number of dimensions from the volumetric representations. A stimulus is applied to the alternative representation, for example by a user employing a force-feedback haptic interface. The response of the alternative representation to the stimulus is calculated. The change in shape of the virtual object is determined from the response of the alternative representation. The representations of the virtual object can be displayed at any time for the user. The user can be provided a force-feedback response. Multiple stimuli can be applied in succession.

Abstract: A rack oven which comprises a baking chamber, a door providing access to the baking chamber, a combustion chamber containing a plurality of in-shot burners, a heat exchanger in combination with the combustion chamber containing a plurality of heat exchange tubes, a steam generator, one or more blower fans for circulating air in a closed path throughout the oven, and a ventor exhaust blower for expelling combustion gases.

Abstract: Apparatus for two-sided cooking comprises one or more upper housing assemblies each having a pair of spaced bayonette members which are removably insertable in a holster brackett. The bracket is readily attachable to the rear of a conventional cooking grill thus retrofitting the grill conveniently for two-sided cooking. A plurality of lightweight platens are mounted in the upper housing by quick release pins which permit the upper platens to float relative to the housing. Because of the lightweight, multiple and floating nature of the upper platens, the housing can be lowered to the grill surface as to completely enclose the items being cooked, thus containing heat and trapping moisture in the cooked product. In addition, food products having differing thicknesses can be cooked simultaneously without appreciable sticking.
