Definitions

  • lr- 9/321 vice can be used to expel water contained in ballast 724179 3/1903 Goldstemm 9/324 tanks of submarines, or to inflate inflation balloons, 867 966 10/1907 FUCI'IS 1 atmospheric balloons, or the 923,801 6/1909 Bargar 9/321 1.014.546 l/19l2 Wich 9/323 7 Claims, 2 Drawing Flgures GAS GENERATOR DEVICE WITHIN AN ENCLOSURE BACKGROUND OF THE INVENTION
  • the present invention relates to a device for generation of gas by reaction of a liquid with a solid or another liquid.
  • the field involved is that of production of gas in an enclosure, which may be inflatable, or an enclosure that is to be made floatable. e.g. ballast tank, submerged buoy or inflatable balloon.
  • the water contained in the ballast tank can be driven out by gas compressed at a pressure above the hydrostatic pressure that prevails at the submersion depth.
  • This compressed gas may be furnished by receptacles filled with a compressed gas at higher pressure, which is expanded.
  • Such arrangements are heavy and bulky.
  • a second method consists in producing a release of gas from a reaction of a liquid or solid material that occupies little space.
  • hot gas generators employing propellants. These generators require an envelope that is resistent to immersion pressure in case of submarine use, and to high internal pressure.
  • generators using propellants release hot gases that may entail serious difficulties, namely the possibility of corroding certain temperature sensitive apparatus or materials, eg joints made of rubber or elastomeric materials.
  • An object of the present invention is to develop a gas generator intended to fill an enclosure with gas, the device being of low bulk, light in weight and inexpensive, releasing a considerable amount of gas per unit of weight, and readily remote-controlled, and able to function under very high pressures.
  • the envelope is filled with a liquid that does not react with the solid or liquid material.
  • the solid or liquid material is preferably a calcium or lithium hydride which reacts with water, producing a release of hydrogen.
  • the liquid that fills the envelope may be a mineral oil or petrolatum, for example: these substances do not react on calcium or lithium hydride.
  • said envelope contains. in addition, an explosive charge, and means are provided for remote control of the detonation of said charge, to cause tearing of the envelope.
  • the invention is thus a new product constituted by a gas generator for filling an enclosure.
  • the generator is very light and of little bulk. In fact, the ratio between the weight and volume of the solid or liquid product on the one hand and the volume of gas obtained on the other is very low, and the supplementary weight and bulk introduced by an entirely flexible envelope are negligible. Thus 0.6 liters of solid carbide release 1000 liters of gas at atmospheric pressure.
  • the generator can operate under very high pressures, of several hundred bars, corresponding to immersion to several thousand meters.
  • the flexible envelope transmits the hydrostatic pressures integrally. It is not therefore subject to any constraints, and it can tolerate very high pressures.
  • the envelope is filled with a liquid, e.g. petrolatum.
  • the remote control of the start of release of gas is readily effected by tearing the envelope.
  • the firing of an explosive charge is a preferred means for effecting this telecommand, because there are many conventional ways to trigger a pyrotechnic charge either by electric conductors, by electromagnetic, or acoustic signals.
  • the gas release is produced very rapidly, as soon as the carbide is put into contact with water, which allows triggering an operation at a precise instant.
  • the generator of the invention can be used for inflation of atmospheric balloons because of its lightness and because it releases hydrogen, which is lighter than air.
  • Generators of the invention can be made inexpensively, which makes it possible to use them in applications that do not require large volumes of gas, e.g. for inflation of buoys, inflation floats or atmospheric balloons.
  • FIG. I is a diagrammatic view in section of a device of the invention, placed in a water-filled enclosure.
  • FIG. 2 is a diagrammatic view in section of a device of the invention, attached to an inflatable balloon.
  • FIG. 1 shows an enclosure 1 filled with water, e.g. submarine ballast, a buoy, a tank or a bell. This enclosure is submerged and presents at the base at least one opening 6 with a grid 7 across which it communicates with the medium that surrounds it.
  • water e.g. submarine ballast, a buoy, a tank or a bell.
  • This enclosure is submerged and presents at the base at least one opening 6 with a grid 7 across which it communicates with the medium that surrounds it.
  • a device of the invention intended to produce a release of gas at the desired time in enclosure 1, forming a bubble in the upper part and modifying the buoyancy of enclosure 1.
  • the device of the invention is shown on a scale that is considerably larger than that of enclosure 1.
  • the device of the invention comprises a sealed envelope 2 which is flexible and which may be torn, containing a solid or liquid material, eg calcium or lithium hydride 3, bathed in petrolatum 4.
  • a solid or liquid material eg calcium or lithium hydride 3, bathed in petrolatum 4.
  • envelope 2 also contains an explosive charge 5, it can be fired at a distance.
  • FIG. 2 shows another application.
  • a device of the invention is hooked to a submerged inflatable balloon 8, eg an inflation balloon for floating a submerged body.
  • the device of the invention serves to inflate balloon 8 at a specific moment, by remote-controlled inflation.
  • the device comprises a reaction chamber 9 furnished in its lower part with an opening 10 that is in communication with the aqueous medium, and in the upper part with openings 11 for passage of gases which communicate with the interior of balloon 8.
  • Chamber 9 is filled with water.
  • a closed envelope l3 sealed at its two ends by diaphragms 14a and 1412, which are readily torn.
  • Envelope 13 if filled with petrolatum 15, in which there are immersed particles of calcium or lithium hydride l6, and explosive charges 17a and 17b, furnished with a remote-controlled triggering device, acting for instance by means of acoustic waves.
  • a device similar to that of FIG. 2 can be used to inflate atmospheric balloons.
  • a device of the invention can be utilized to drive out water contained in submarine ballast tanks as well as in a reservoir, buoy or submerged bell, or to inflate submarine inflation balloons or atompsheric balloons, this listing not being limitative.
  • a gas generator device for an enclosure comprising a sealed, flexible, deformable envelope which, in

  • a device as in claim I wherein said non-reactant liquid in the envelope comprises a mineral oil.
  • said deformable envelope comprises a pouch.
