Liquid nitrogen enabler

Abstract

This invention is a means to quell uncontrolled fires, dissipate low-pressure cells in tornado-producing clouds and make ordinance as mines, old bombs and the like inert and provide a design opportunity for lava flows. For each operation, one applies unique means of distribution of Liquid Nitrogen, either above the surface sufficiently to allow it to rain down from holes in a trough forming a pattern in the bottom of an encircling or linear trough held up with stakes or legs of a length optimum for maximum evaporation before hitting the surface, or underground with drilling means or preparatory piping or well placed air drops of Liquid Nitrogen. This produces local cooling and expansion of inert gas supplanting the general atmosphere with a nitrogen atmosphere reducing significantly the amount of oxygen available and increasing the atmospheric pressure. Both cooling and flooding with inert gas quickly quell of fires. The expansion of gas sprayed in tornado-producing clouds raises the atmospheric pressure. Cooling renders inert fused ordinance as mines and bombs. They cannot explode or detonate at these extremely low temperatures. Liquid Nitrogen can control both lava flows and flooding making the flowing liquid a solid by lowering its temperature.

Therefore I claim:  
     
         1 . A method of enabling Liquid Nitrogen's usefulness in both cooling and providing inert gas, nitrogen, (N 2 ), in a designated location by raising its distribution channel, trough, above the surface high enough to get maximum temperature change for cooling by conduction and evaporation and through evaporation to produce an inert atmosphere before it skitters away from the targeted event.  
     
     
         2 . A method, according to  claim 1 , that allows selection of the trough height by dimension of the stake to give the maximum desired effect be it cooling the target event or item or flooding it with an inert Nitrogen gas atmosphere or both.  
     
     
         3 . A method, according to  claim 1 , to increase the volume of this Liquid Nitrogen rain by putting the holes in the trough in a pattern, as, but not limited to, a zigzag pattern, to make the rain fall over a wider line or circumference line width as defined by the trough unit shape.  
     
     
         4 . A method, according to  claim 2 , which allows the trough to be constructed in units to give ease of transport and assembly such that the plural of them constructs the desired shape of the trough unit be it linear, circular or irregular in shape.  
     
     
         5 . A method of pouring the Liquid Nitrogen from the source in multiple directions, as for two directions using a “T” nozzle affixed on the dewar spout so Liquid Nitrogen pours evenly out each side of the “T” top into, for example, two linear segments going in opposite directions or both directions in a circle configured trough.  
     
     
         6 . A method in  claim 5  of pouring Liquid Nitrogen underground as having the dewar pipe installed in a drill bit carrying the flow origin at the end of the bit.  
     
     
         7 . A method to quell uncontrollable fires by replacing the atmosphere with a nearly nitrogen pure atmosphere and drawing energy from the fire by cooling by convection and by evaporation.  
     
     
         8 . A method of increasing the atmospheric pressure with infusion of Liquid Nitrogen where a unit of Liquid Nitrogen equals 250 units of atmospheric temperature gas as in raising the atmospheric pressure in an active tornado eliminating the airflow pattern giving it its destructive power.  
     
     
         9 . A method to inactivate an explosive device as, but not limited to, a mine, by lowering its temperature to the point that it becomes inert and then while it is so cooled, removing it, keeping it at Liquid Nitrogen temperature until it is in an appropriate place as a detonation chamber.  
     
     
         10 . A method, according to  claim 9 , that cools locations of buried ordinance or mines by placing Liquid Nitrogen at its suspected depth for safe removal and protection of the function of what it was placed to destroy.  
     
     
         11 . A method of cooling a liquid flow so its solid form dams the continued flow.  
     
     
         12 . A method in  claim 11  that allows design of the site of flow stoppage so future flows are controlled from passing into the established positions.
