摘要： A gas oven comprises at least a first burner element disposed within an oven cavity of the gas oven. A first control valve is disposed within a gas line connected to the burner element and to a gas source. The control valve controls gas flow to the burner element. A first temperature sensor is positioned so as to detect temperature about the burner element. A controller is electrically coupled to the temperature sensor and to the control valve wherein the controller ensures successful ignition of the burner element by monitoring the temperature signals generated from the temperature sensor to determine if the temperature signals increase a rate that is greater than a predetermined.

摘要： A gas burner assembly for connection to a source of gas comprises a burner body having a sidewall and a main gas conduit. The main gas conduit has a burner throat and the sidewall has an inner surface, an outer surface and a top surface. A plurality of primary burner ports are disposed within the sidewall dividing the sidewall into a plurality of sidewall islands. A burner cap is removeably disposed on the sidewall. A plurality of paired opposing ridges are disposed on the top surface of the sidewall wherein a single pair of opposing ridges are disposed on a respective sidewall island so as to define a plurality of carryover slots between the opposing ridges, the top surface and the burner cap. Each carryover slot has an inlet and an outlet. The paired ridges comprise a radial taper that narrows from a point adjacent the inner surface of the sidewall to a point adjacent the outer surface of the sidewall such that the flow area at the inlet of the carryover slot has a value that is less than the value of the flow area at the outlet of the carryover slot so as to reduce fuel-air mixture velocity and produce a low velocity, stable carryover flame that reduces the tendency of the main flame to lift.

For example, the coatings can be applied using ion plasma deposition, sputtering or wire arc techniques (all PVD processes) or by using electroplating, high velocity oxygen free (“HVOF”) deposition, DC arc or electroless plating. Preferably, the coatings are applied either to new stator bar clips or to existing clips in the field.

摘要： A gas oven having an electronic controller for directly controlling the gas valve and burner ignition. The controller opens the gas valve and activates the ignitor whenever oven heating is required and then determines whether ignition has occurred, detected by an indicator of ignition, often a conventional oven thermostat, a thermocouple, a resistance temperature device (RTD), or other type of temperature sensor. Positive proof of ignition is given by determining whether the detected temperature is increasing at a particular rate. The gas valve is closed if ignition does not occur within a predetermined time, preferably about 10-15 seconds. Re-ignition may be attempted after a sufficient delay. The controller also closes the gas valve whenever the oven temperature is decreasing at a predetermined rate or is increasing at less than a predetermined rate.

摘要： A brazed joint between an armature bar strand package and an end fitting is provided where a plurality of solid strands and a plurality of hollow strands are arranged in an array. The plurality of hollow strands have free ends that extend axially beyond corresponding free ends of the solid strands. A cavity in the end fitting is accessed by an opening, and the free ends of the plurality of hollow and the corresponding free ends of the solid strands extend through the opening into the cavity. A braze alloy joins the free ends of the plurality of hollow strands and the corresponding free ends of the plurality of solid strands to each other and to interior surfaces of the end fitting, wherein the braze alloy does not extend substantially beyond the free ends of the solid strands. A related method of forming the brazed joint is also disclosed.

摘要： An ignition system for a gas appliance comprises an ignition controller that receives a current from a power source. The ignition controller is also coupled to an ignitor and to a current actuated valve that releases a flow of gas when the current is greater than a first predetermined current value and less than a second predetermined current value. Ignition safety for the gas appliance is provided by establishing a fixed range of current through the ignitor before the gas valve is opened.

摘要： A gas burner assembly for connection to a gas source includes a burner body having a sidewall and a main gas conduit. The burner body further includes a number of primary burner ports disposed within the sidewall, each for supporting a respective main flame, and a simmer flame port disposed within the sidewall adjacent to the primary burner ports for supporting a simmer flame. Additionally, a main fuel chamber is disposed within the burner body to provide fuel to the primary burner ports, and a stability chamber is disposed within the burner body to channel fuel to the simmer flame port. In one configuration, the stability chamber has one or more stability inlets proximate the burner throat which provide the stability chamber with fuel by utilizing the static pressure associated with each stability inlet. In another configuration, the stability chamber has a small feed hole located proximate the burner throat of the main gas conduit. Each configuration creates a comparatively large pressure drop across the stability chamber during fuel flow due to the positioning of the stability inlets or the feed hole proximate the burner throat, thereby reducing the sensitivity of the simmer flame to pressure disturbances.
