Machine for producing dispersions of liquids in air or other gases for the production of fogs

Claim 2

IN A FOG GENERATOR HAVING A PULSE JET ENGINE INCLUDING A COMBUSTION CHAMBER AND A DISCHARGE TUBE AND ADAPTED TO DEVELOP A PULSATING DISCHARGE PRESSURE THROUGH SAID TUBE, SAID DISCHARGE TUBE HAVING A CURVED PORTION WITH A LOW POINT INTERMEDIATE THE ENDS THEREOF, A RESERVOIR CONTAINING A FORMULATION FOR DISCHARGE IN THE FORM OF A FOG THROUGH SAID DISCHARGE TUBE, MEANS FOR SUPPLYING SAID FORMULATION TO SAID DISCHARGE TUBE AT A POINT DOWNSTREAM THEREOF AND AT A HIGHER LEVEL THAN SAID LOW POINT, AND A DRAIN CONNECTION TO SAID LOW POINT HAVING A RESTRICTED PASSAGE FOR VENTING UNDISCHARGE QUANTITIES OF SAID FORMULATION UPON THE STOPPAGE OF SAID ENGINE AT A POINT REMOTE FROM SAID DISCHARGE TUBE.

Claim 3

IN A FOG GENERATOR HAVING A PULSE JET ENGINE INCLUDING A COMBUSTION CHAMBER AND A DISCHARGE TUBE AND ADAPTED TO DEVELOP A PULSATING DISCHARGE PRESSURE THROUGH THE TUBE, A CLOSED RESERVOIR FOR STORING A FORMULATION FOR INTRODUCTION INTO SAID TUBE TO PRODUCE THE FOG, A CONNECTION FROM SAID RESERVOIR TO SAID DISCHARGE TUBE FOR DELIVERY OF SAID FORMULATION THERETO, A PRESSURIZING VALVE HAVING A CHECK VALVE MEMBER ADAPTED TO OPEN AUTOMATICALLY IN RESPONSE TO SAID PULSATING PRESSURE AND TO ALLOW PASSAGE OF ONLY THE PRESSURE PEAKS FROM SAID COMBUSTION CHAMBER, A RELATIVELY SHORT CONNECTION FROM SAID COMBUSTION CHAMBER TO SAID PRESSURIZING VALVE HAVING LOW FLOW RESISTANCE PROVIDING FOR EFFECTIVE DELIVERY OF SAID PRESSURE PEAKS FROM SAID CHAMBER TO SAID VALVE TO FORM A CONTINUOUS PRESSURE, AND A RELATIVELY LONGER CONNECTION FROM SAID PRESSURIZING VALVE TO SAID RESERVOIR TO TRANSMIT SAID CONTINUOUS PRESSURE TO THE INTERIOR OF SAID RESERVOIR TO ESTABLISH AN EXPELLING PRESSURE THEREIN.

Claim 4

IN A FOG GENERATOR HAVING A PULSE JET ENGINE INCLUDING A COMBUSTION CHAMBER AND A DISCHARGE TUBE AND ADAPTED TO DEVELOP A PULSATING DISCHARGE PRESSURE THROUGH THE TUBE, A CLOSED RESERVOIR FOR STORING A FORMULATION FOR INTRODUCTION INTO SAID TUBE TO PRODUCE THE FOG, A CONNECTION FROM SAID RESERVOIR TO SAID DISCHARGE TUBE FOR DELIVERY OF SAID FORMULATION THERETO, A PRESSURIZING VALVE HAVING A CHECK VALVE MEMBER ADAPTED TO OPEN AUTOMATICALLY IN RESPONSE TO SAID PULSATING PRESSURE AND TO ALLOW PASSAGE OF ONLY THE PRESSURE PEAKS FROM SAID COMBUSTION CHAMBER, A RELATIVELY SHORT CONNECTION FROM SAID COMBUSTION CHAMBER TO SAID PRESSURIZING VALVE HAVING LOW FLOW RESISTANCE PROVIDING FOR EFFECTIVE DELIVERY OF SAID PRESSURE PEAKS FROM SAID CHAMBER TO SAID VALVE TO FORM A CONTINUOUS PRESSURE, AND A RELATIVELY LONGER CONNECTION FROM SAID PRESSURIZING VALVE TO SAID RESERVOIR TO TRANSMIT SAID CONTINUOUS PRESSURE TO THE INTERIOR OF SAID RESERVOIR TO ESTABLISH AN EXPELLING PRESSURE THEREIN.
