A gas grill having a visible indicator for indicating ignition of the grill burner. The indicating device includes a sensing device mounted adjacent the burner on a common bracket with a burner igniter. The control for the igniter is mounted in a common housing with the ignition indicator. An encapsulated spark gap, neon bulb, or similar device is connected with the spark igniter for indicating that a spark has jumped an electrode gap.

Ignition indicator for gas grills

A spark igniter for gas grills includes a gas collector mountable on the grill housing adjacent a gas burner and having a collector inlet for receiving gas from the burner. An adjustable mounting device attached to the collector provides vertical adjustment of the collector for positioning the collector inlet at a proper elevation for receiving gas from the burner. The adjustable mounting device also serves to attach an electrode to the collector and position the electrode tip in a predetermined location for defining a spark gap.

Gas collector/igniter for grills

A spark igniter for gas burners includes a gas collector having a passage extending between open front and rear ends. The open front end is substantially larger than the open rear end, and is positionable adjacent a gas burner for receiving gas therefrom. Gas flows into the open front end of the collector and mixes with air to form a combustible mixture. A spark igniter mounted within the gas collector passage ignites the mixture to produce a flame for igniting the gas burner. The gas collector is metal and forms the ground electrode for the spark igniter, and has an integral mounting bracket thereon.

Gas collector/spark igniter for gas burners

In the manufacture of wave filters, such as FM filters, polarized piezoelectrically responsive wafers are provided, temporarily, on the active regions thereof, with a removable material. Subsequent to the encapsulation of the wafer by a protective but porous coating, the filter is heated and the removable material sublimates through the porous coating establishing a wafer surface substantially free of residual impurities and leaving an uninterrupted cavity between the wafer and the coating in the active regions. The preferred sublimatable material is paradichlorobenzene.
