Abstract: A strain gauge pressure transducer comprising a housing having an internal pressure cavity across which is mounted a flexible elastomeric diaphragm that separates high and low pressure chambers in the gauge that the housing is arranged to separately connect the sources of high and low pressure, respectively. A range spring in the form of a leaf spring is anchored to the housing cantilever fashion in the high pressure chamber and to one side of the diaphragm to dispose the live length of same, as defined by a clamp device, in overlying relation to the diaphragm, to which the leaf spring live length is connected for deflecting movement thereof by the diaphragm.

Abstract: The invention relates to an ignitor box, or chamber, for use with a gas fired grill wherein a piezoelectric device strikes a spark that ignites the gas from an adjacent burner. This ignitor chamber is of flared form enclosed on three sides with the fourth side open and facing the burner for admission of gas into the chamber directly from the burner. The top and bottom walls of the chamber are also enclosed, but the top wall is provided with a raised cupola open at opposite ends for the circulation of air:(1) to effect the admission of oxygen for mixture with the incoming gas from the burner to provide a more combustible mixture for ready ignition when the spark is struck;(2) also to allow dissipation of combustion gases trapped in the ignitor chamber immediately after combustion.

Abstract: This invention relates to a pill box comprised of three parts including a shell bottom, a shell top and a slip ring so interrelated that the slip ring holds the top and bottom parts assembled with the slip ring rotatable relative to the assembled parts. The top and bottom parts are nonrotative relative to each other and are formed to cooperate to form a pill discharge opening normally closed by the slip ring with the ring formed with an opening adapted to be aligned with the discharge opening for discharge of a pill from the assembled box.
