Abstract: A gas-air flexible tubing assembly for use for interconnecting a supply of gas, such as bottled gas, to the burner of a cooking grill, the flexible tubing formed of helical coiled wire, and coated with a flexible and expandable polymer, interconnects with, at one end, and air-gas intake tube, by means of a threaded connection, and connects, at its opposite end, by means of a threaded connection with the downward extension of an adapter, for securement of the assembly to the underface of the burner element of a gas grill.

Abstract: A fire sound simulator includes a random sequencer which produces random signals. The sequencer is connected to a sound synthesizer which transforms the sequencer's signals into random sounds. The synthesizer is in turn connected to a speaker which receives the sounds from the synthesizer for outputting the sounds. The simulator alternatively includes a recording stored on a ROM chip. The simulator may be activated by a light sensitive switch.

Abstract: A self-contained gas light control module is disclosed as including a tubular housing with a main tubular gas line extending through the housing and a normally open electro-mechanical valve in the gas line to permit flow of gas therethrough at night. During day light hours, a solar cell is activated to close the normally open electro-mechanical valve and shut-off the main tubular gas line; however, a smaller by-pass gas passageway or line is connected around the electro-mechanical valve to permit a smaller amount of continuous gas flow around the electro-mechanical valve, when closed, for low pilot flame burning of the gas light during day light hours.

Abstract: A gas fired cooking grill having a twin burner element initially adapted for dual gas supply lines is disclosed as including an adaptor manifold for converting the twin burner element to a single burner element for a single gas supply line source. The adaptor manifold includes an enclosed chamber which is mounted in sealed engagement to the burner element and has an adjustable mounting for connection to a single gas supply line source.

Abstract: An adjustable gas tube assembly is disclosed for use with gas consumption means (including gas barbecue grills) and includes a gas delivery tube having a tubular air regulator member mounted therein at one end. The tubular air regulator member includes at least one elongated lateral opening which is selectively exposed, as desired, as the tubular air regulator member is inserted or withdrawn from the gas delivery tube. The tubular air regulator member is preferably provided with a restricted throat for gripping and retaining a gas supply tube section connected to a gas supply source. The tubular air regulator member is also preferably used with a flexible and expandable gas delivery tube.
