In particular, some recent inventions are related to means for cleaning floors and surfaces using the so-called dry ice. They have the characteristic of a more effective removal of fat in respect of the common cleaning methods based on detergents.
Another class of machines is given by artificial snow means, widely used in tourist plants in case of lack of snow on mountains during winter.
All the above machines have the serious drawback of not permitting to change the calibre for the particles of ice and of not permitting to direct a high rapid jet of them towards a specific target.

BEST MODES FOR CARRYING OUT THE INVENTION
It is herein underlined that, in the following, only some of the many conceivable embodiments of the present invention will be described, and they are just particular examples that do not introduce any limitations, having the possibility to describe many other embodiments based on the disclosed technical solution of the present invention.
In figure 1 it is illustrated a gun 10 that is the main part of the machine which is the subject of the present invention (third stage) . In particular, it receives
some bullets 12 going inside, that are externally generated and then carried on using the containing elements 82 (figure 8) locked on a mobile transportation chain 110 (figure 11) . Each single containing element 82 is composed of two hemispheres holding a bullet of ice 12 inside. When the mobile chain 110 makes an element 82 to arrive close to the gun 84, a proper mechanism provides the two hemispheres to open and to release the contained bullet of ice 12. Then, the bullet 12, located in the ballistic barrel 13, is ready to be instantaneously launched outside using a proper launch mechanism 14. This mechanism 14 is switched on by gears connected to a trigger 15, pushed by an external user that is responsible to λfire' a shot. Said situation is better represented in figure 2 where it is illustrated, using arrows, the motion of mechanisms 23, 24, 25 and 26, and the consequent instantaneous launch of bullet 26 going outside.
The system has been designed so that there is a cyclic rate, and when a shot has been fired it is immediately possible to fire again, according to a rapid load of a new bullet, in a ^machine gun' style.
Indeed, in order to make it possible, new bullets should be generated in real time and continuously. That is realized by the following described process and devices.
In particular, elements 82 go to *■catch' a specific quantity of water from the inner side of a tank 50 like the one of figure 5 (first stage) .
Pipelines 51 and 52 allow the above said mobile transportation chain to run inside the tank. Each containing element 53, according to an open/close mechanism of the two belonging hemispheres 57 and 59, holds a definite quantity of water inside. The same quantity of
water is carried outside the tank following the run of the mobile transportation chain.
In figure 4 it is better illustrated how input 43 and output 42 pipelines allow the transportation of water outside tank 41.
In the design of the present machine, a particular attention has been addressed to the closing mechanism of said spherical containing elements. In fact, it is clear how this closing operation must be not only extremely fast and efficient, but also perfectly ■ Watertight' . Some thin 0-rings, made of rubber polymeric material, joint on the respective edges of said hemispheres, are able to reach this objective.
Another critical aspect of this machine is given by the connection element of pipelines 51 and 52 inside tank 50. In fact, once a containing element 58 holds a specific quantity of water inside, and it is going outside the tank, it is important that water is not pushed towards the output pipeline 52. In other words, the connection element between tank 50 and output pipeline 52 should allow the passage of a solid element, the spherical container 58, but not the passage of a liquid element like the water of the tank. This result is 'obtained by providing a proper open/close mechanism with 0-rings, valves and a possible integrated drainage system by pressure.
A similar problem is located at the άnput pipeline 51. In fact, a connection element should guarantee the passage of a spherical container 53 going inside and avoid the simultaneous flowing back of water from tank 50 to the pipeline 51. Another open/close mechanism with 0-rings, valves and a possible integrated drainage system by pressure can solve the problem and obtain the desired result.
Once each containing element 58 runs outside tank 50, carrying away a definite quantity of water, proper pipelines drive it to another device, a cooling device 70 - figure 7 (second stage), that provides, for the objects going through it, a very fast cooling process going to extremely low temperatures.
Consequently, the water inside is subject to a very quick change of state, from the liquid state to the solid one, transforming itself in a small block of ice quite instantaneously. The geometrical shape of the small block of ice is defined by the above said containing element that, exactly for this reason, is indicated with the name of λmould' . In fact, the mould defines size and consistency of said bullets of ice, giving then, indirectly, the level of wounding power (from non-lethal to lethal bullets) .
From a technical point of view, the nearly instantaneous passage from room temperature to an extremely lower temperature states nontrivial problems.
The most appropriate solution is to introduce some heat exchange devices 73, with highly thermal conductive walls, where a fluid, having a temperature close to absolute zero, like liquid hydrogen or helium, is forced to circulate.
This solution, together with a size of few millimetres for said ice bullets, can guarantee the passage of water, from a liquid to solid state, in a split, second.
In figure 6 it is illustrated more in particular how pipelines 65 and 68 permit: first the spherical containers
61 (with water inside) to enter in said cooling device 60, and then the spherical containers 62 (with ice. inside) to exit from the same cooling device 60.
In such a way, the process of real time generation of bullets of ice is complete. These bullets are immediately available in sequence to the gun 84 so that the user can
shoot immediately towards an external target. In figures 9 and 10 the proper mechanisms, for using the gun with ice bullets, are illustrated again.
The global machine, in this embodiment, appears like that illustrated in figure 3. A water tank 32 guarantees the raw material that, going through pipelines 35, is driven to a cooling device 31 where ice bullets are generated. Additional pipelines 36 make the same ice bullets immediately available to a gun 33, where they can be shot to an external target. A pipeline 34 drives the moulds to Λcatch' new material before repeating the cycle again and again for an indefinite number of times.
In figure 11 it is illustrated the transportation chain 110 that drives the containing elements 115 through the entire machine. As already mentioned, each container is composed of two hemispheres (i.e. 11 and 112) that can be hermetically sealed, in order to contain a definite quantity of water inside, and then to open again in order to release the material that is stored inside. Naturally, in order to make the chain 110 to run in the pipelines for an indefinite quantity of time, it should be dragged by a proper external device.
A first possible solution is that pressure vacuum, consequent to a bullet firing, can give the necessary energy to keep the chain 110 in motion. Another more realistic solution is to integrate, in. the machine, an automatic dragging device that provides the motion of chain in a programmed cyclic sequence.
Another significant characteristic of chain 110 is the presence of articulation means 113, with one. or more degrees of freedom, so that it is possible to follow the curves and bends of said pipelines in the three-dimensional space.
In synthesis, in figure 12 it is represented a global schematic view of each part belonging to this machine, including all the above described devices with reference to generation, load and instantaneous launch of bullets of ice .
According to the above basic principles, it is possible to introduce additional embodiments of this invention. As already mentioned, in case of weapon available to police or military forces, the ice bullet gun can be represented in figure 3, with a main structure on ground so that the user is free in respect of weights and bulks.
However, another solution is to locate the entire machine on a mobile trolley so that it is possible to have a very big and heavy tank of water. In some cases, it is possible to have a significant extension of uses if this invention is mounted on a big vehicle, a truck, a train, a ship or a helicopter.
In such a way, it appears particularly suitable, e.g., to fast extinguishing fires, diffusion of artificial snow on winter sport plants, fast cleaning service of buildings or monuments affected by pollution's dust, and fast disinfection of areas affected by viral or bacteriological agents. Furthermore, another embodiment of the present invention is given when the user can carry this machine directly on his body, with water tank and cooling device on shoulders, and gun ready to shoot ice towards fast moving targets. Such a machine would be particularly suitable to police forces, fire brigades, military forces -and rapid reaction forces.
Therefore, all of the above examples show that the present invention achieves the proposed objectives. In particular, it permits to realize a machine able to shoot
particles of ice, with high speed, towards a specific target.
Then, it permits to realize a machine with bullets of ice having a variable calibre, it being possible to choose the granularity level and the robustness level for the same bullets.
Furthermore, the present invention introduces a perfectly autonomous machine, in a sense of not requiring outer sources as raw material or energy, and able to make the necessary ice bullets in real time and continuously starting from an available quantity of water.
The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is clear that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope, as defined in the enclosed claims.
