Abstract

1388419 Audible signalling apparatus SAFE FLIGHT INSTRUMENT CORP 29 Feb 1972 [10 March 1971] 9361/72 Heading G4F A control system for a gas blown fog horn comprises an inlet plenum 16 communicating with a pressurized gas source 12, an outlet plenum 18 communicating with the fog horn 10, manually operated means 40 for placing the inlet and outlet plenums in communication, and automatic means for periodic operation of the horn. In automatic operation, gas flows into timing chamber 22 through opening 28 and snaps spring diaphragm 24 to its outer position, thus opening valve 30 by means of rod 32a and also opening valve 48 by means of a bell crank lever. Since opening 28 is smaller than the opening of valve 30, pressure is reduced in chamber 22 and diaphragm 24 moves to its inner position thus closing valves 30 and 48; the cycle is then repeated. A control device 26 holds the diaphragm in its inner position and is released to allow the diaphragm to move for intermittent operation of the fog horn. In a modification, Figs. 4-6 (not shown), the valve between the inlet and outlet plenums is opened only by manual operation and not by movement of the diaphragm during automatic operation.
