Definitions

  • the invention relates to a method of applying liquid nitrogen to crises and, more particularly, relates to a method of applying liquid nitrogen to eliminate Oxygen from airmass and to apply cold inert gas to freeze, condense and allow recovery of material.
  • Liquid Nitrogen can be applied to flood a volume with cold, inert Nitrogen gas in the case of anticipated explosion such that, once people are suitably cleared either fixed Liquid Nitrogen dispensers or inserted dispensers fill the structure or vehicle with Nitrogen gas when there is an unsourced gas leak, Methamphetamine lab activity is suspected or flammables have spilled and remain out of control. Also here, a Nitrogen atmosphere may be maintained through volatile material leaching processes where both the solvent added and the contaminant material could ignite.
  • Resuscitation is immediate once Oxygenated air is available and a stroke or two of Artificial Respiration is applied to draw it into the lungs. There is time to apply restraints before bringing dangerous beings back to consciousness and normal breathing.
  • the Nitrogen atmosphere is generated in defense against future explosion protecting those in the vicinity, those working the situation and the operation for ongoing use of flammables to insure safety and purity of the chemistry.
  • a method of using the cold, inert air to cause toxins, industrial smokestack exhaust and cooling to extinguish long term coalmine fires can enable collection of gaseous or particle components of the air or smoke or condense it in the ground as coalmine fires become extinguished.
  • a second freezing can allow removing the caps on the pipe ends and installing the permanent repair. Once thawed, the pipe system is back in service.
  • a method of using liquid nitrogen after being deployed by aircraft and showered into a developing tornado cloud might instigate change in the threatening situation by changing to markedly reduce temperature and raise the air pressure to hinder or disrupt the formation of an effective tornado.
  • a matrix of pipes set into soil or mixture of materials which serve as the holding soil against mudslide or levee against floodwaters, when crises situations develop as extreme rains or Category #5 Hurricane, Liquid Nitrogen can be poured through the pipe system freezing the water in the soil to components making a concrete hard core the length, width and height of the pipe system.
  • a method of applying a matrix of piping that with Liquid Nitrogen running through it will freeze water making a barrier or blockage for a small orifice flooding situation like dike breakage or dam rupture.
  • This matrix can be frozen in a slow flow area and drawn into the fast flow at the orifice and guided to lay flat against the ruptured dike or dam segment.
  • the ice barrier should hold back the water.
  • Making the matrix cup shaped may allow dike or dam repair before melting the barrier.
  • inventor Page 9 can be set in place ahead of the lava mass in the direction it moves, such that when the pipes are approached, Liquid Nitrogen can be pumped through them cooling first the pipes and then the lava encountering the pipe system to solidify the flow molding it and, using the pipes after solidification to carry water and wiring, a lava stone structure stands.
  • Liquid Nitrogen can flood the burn zone for coalmine fires and can instantly cool and condense stack gas emissions.
  • Gaseous Nitrogen as it is generated will stay in a homogeneous cloud of Nitrogen unless a disrupting wind of five miles an hour or stronger whips it into a mixture of air gases, as swirling in Oxygen, Argon, water, Carbon dioxide, and other components. It is this exclusivity, homophobicness that allows the Nitrogen cloud to eliminate Oxygen from a fire, from breathe intake, from combustion engines requiring Oxygen in the air mix, and from a potential explosion situation. In engineering dispersal of a toxin to the point where it is ineffective, if that is a desired thing, Nitrogen gas will clear away other components of the air.
  • FIG. 1 shows a half-circle pre-set Liquid Nitrogen dispenser having flooded a building where hostages have been taken. Emergency responders have adequate Oxygen masks in hand to enter the building and resuscitate everyone and handcuffs and any other restraints for the hostage takers. This can apply to Methamphetamine Labs as well.
  • FIG. 2 shows precautionary flooding with Nitrogen gas, areas where an explosion may be anticipated either on discovery of a situation or, when operating chemical processes with flammables, one chooses to work in a cold, inert, defined atmosphere.
  • FIG. 3a is a view of direct Liquid Nitrogen rain on an aerosol spewing a toxic substance freezing the substance in the can.
  • a mason jar with cap can contain the frozen aerosol to prevent further disbursement of the toxic substance.
  • FIG. 3b is a view of the sieve for direct application on a toxin cloud, which could
  • FIG. 4a is a view of the sieve for cooling a spill to gel or solidify the material for pick up.
  • FIG. 4b shows cleanup if the surface doesn't allow easy removal of solidified material, flood the area with water to lift the spill and then solidify it using a skimmer to pick up the material.
  • FIG. 5 shows a sequence used to stop the flow from a ruptured pipe, sealing the broken ends followed by refreezing and repairing the breakage and returning the pipe to service.
  • FIG. 6 is a schematic illustration of how to put combustion engine machinery out of operation by flooding air intake with Nitrogen gas and, at the same time, severely cooling engine and battery.
  • FIG. 7 is a schematic view of an aircraft delivering a quantity of Liquid Nitrogen for dissipating into a tornado cloud to change the convection flow, thermal patterns that might support tornado activity imminently, and by increasing the air pressure in the storm cloud.
  • FIG. 8 is a pipe matrix, this one installed in soil or composition structure as a suspected mudslide area or levee holding water back. When crises threaten, Liquid Nitrogen is run through the pipe systems freezing the suspected mudslide areas or levees.
  • FIG. 9 shows another pipe configuration, which, when Liquid Nitrogen runs through will freeze water forming an ice cover for a dike break or dam rupture, and, not shown, allow for repair while frozen and then melting the ice when dike or dam is fixed.
  • FIG. 10 is yet another pipe configuration which is designed to sculpture a lava flow when it reaches it, to allow a useful permanent structure once the lava flow solidifies.
  • the front component shows new lava flow. In back, the finished form.
  • FIG. 11 shows the means to penetrate the ground around a coalmine fire with Nitrogen which reduces the burn until the fire is out. Flooding the mine with excess Liquid Nitrogen left in the truck will further hasten the coalmine fire control.
  • FIG. 12 shows means to capture the industrial smoke stack emissions, condensing them before they enter the atmosphere to pollute the air. Reuse of captured components is recommended.
  • One such use is running components through a green house system. Capturing the water from the smoke lets the particulates drop. Carbon dioxide run through a lighted greenhouse will cause plants to photosynthesize exchanging the Carbon dioxide for Oxygen. The water irrigates the plants. The soot can be mixed into the soil or compressed into charcoal shapes and burned.

After the Liquid Nitrogen dispensing unit is inserted in the opening 31, to prevent outside air from mixing with the Nitrogen gas, a covering 32 is inserted to block airflow from outside the target area in the building. An inserted dispenser can be markedly smaller and more stealth than what is shown 10, so as not to arouse curiosity.
  • FIG. 2 shows another embodiment of the present invention wherein a facility 40, here resembling a silo or storage chamber, where a flammable situation may develop, as with accumulating Methane Gas in a corn storage unit, has a built in Liquid Nitrogen dispenser 14 into which a dewar of Liquid Nitrogen 16 is emptied such that gaseous Nitrogen 2 displaces other gases accumulating in the facility 40, purging the explosive gases as it billows out from the pressure of the Nitrogen gas dispensed into the chamber.
