Claim 1

A WATER LAUNCHABLE, INFLATABLE BALLOON AND GAS GENERATOR COMBINATION COMPRISING, A BALLOON HAVING AN OPENING FORMED THEREIN, A GAS GENERATOR CONNECTED TO SAID BALLOON AND HAVING MEANS CONDUCTING GAS FROM THE GENERATOR, THROUGH SAID OPENING AND INTO THE BALLOON, SAID GAS GENERATOR INCLUDING A WATER PERVIOUS CONTAINER; A QUANTITY OF EXPENDABLE CHEMICAL IN SAID CONTAINER ADAPTED TO COMBINE WITH WATER TO PRODUCE A LIGHTER THAN AIR GAS, CONDUIT MEAN INTERPOSED BETWEEN AND FLUIDLY COUPLING SAID GAS GENERATOR WITH THE OPENING IN SAID BALLOON TO CONDUCT GAS, AND ANY WATER ENTRAINED WITH SAID GAS, FROM GENERATOR INTO SAID BALLOON, SAID CONDUIT MEANS COMPRISING A PLURALITY OF PASSAGES IN FLUID COUPLED RELATION DEFINING IN SUCCESSION A FIRST UPWARD FLOW PATH FLUIDLY COUPLED AT ITS BOTTOM TO SAID GAS GENERATOR, A DOWNWARD FLOW PATH FLUIDLY COUPLED AT ITS UPPER END TO THE UPPER END OF SAID FIRST FLOW PATH, SAID DOWNWARD FLOW PATH HAVING AN INTERMEDIATE OPENING, AND A SECOND UPWARD FLOW PATH FLUIDLY COUPLED TO THE OPENING IN SAID DOWNWARD FLOW PATH, WHEREBY THE GAS AND ENTRAINED WATER ARE CONSTRAINED TO FLOW TOGETHER UPWARDLY IN SAID FIRST UPWARD FLOW PATH UNDER THE DYNAMIC PRESSURE OF THE GENERATED GAS AND THEN DOWNWARDLY IN SAID DOWNWARD FLOW PATH UNDER THE INFLUENCE OF BOTH THE DYNAMIC PRESSURE AND THE FORCE OF GRAVITY, THE GAS BEING CONSTRAINED TO ESCAPE DUE TO ITS LIGHT WEIGHT VIA SAID OPENING AND VIA SAID SECOND UPWARD FLOW PATH INTO SAID BALLOON, WHILE THE WATER IS CONSTRAINED BY ITS WEIGHT TO CONTINUE FLOWING DOWNWARDLY PAST SAID OPENING IN SAID DOWNWARD FLOW PATH, WHEREBY ONLY GAS ENTERS THE BALLOON, AND RESILIENTLY BIASED FLOW RESISTING MEANS COUPLED BETWEEN THE UPPER END OF THE SECOND UPWARD FLOW PATH AND THE ENTRANCE TO THE BALLOON FOR PROVIDING A PRESSURE HEAD TO PREVENT THE OCCURRENCE OF A LEVEL OF FREE WATER IN COMMUNICATION WITH SAID OPENING IN THE DOWNWARD FLOW PATH.
