1 BALLISTIC RECOVERY SYSTEM

2 A. Introduction Obtaining test standards of fired ammunition components (bullets and cartridge cases) as a basis for comparison with the class and individual characteristics of evidence items is the first step in the identification process. Fired cartridge case collection is relatively simple. However, fired bullet samples must be collected using techniques that decelerate and securely capture the fired bullets within a short distance. The overarching requirement is that this be performed without damage to the microscopic detail on the surface of the fired bullets. A few basic types of recovery devices have evolved, including the cotton box and water recovery tanks. Recovery Equipment The automated recovery RDX3 precisely has the function of collecting witness bullets in the best structurally possible conditions, getting a consistent reproduction of individual characteristics that are transferred by rifling the barrel of each gun, which is used in forensic identification studies of firearms and tool marks using microscopic techniques comparison. B. Legal Notice The standard bullet recuperator, registered trademark RDX3, has the international patent number: , in addition it has a second patent in process of registration; case file; MX/a /2015/013633, which corresponds to the innovative device to exchange the speed reducer seal of the projectiles. Therefore its manufacture is really exclusive, because the RDX3 tank, is manufactured directly by the inventors and owners of this new technology.

3 C. Innovative receptacle with hatch and interchangeable seal The receptacle of the RDX3 is a novel attachment made of high-strength polyethylene, incorporated inside the chamber containing the liquid, which also has an external hatch, hinged and lever, with easy opening and closing, allowing Change the polyurethane foam cartridge quickly and easily. The polyurethane foam cartridge has the function of a seal to prevent the expulsion of water in the direction opposite to the projection of the shot, due to the hydraulic effect that occurs inside the tank, preventing the liquid is directed in the opposite direction where the initial firing force was applied, which would correspond to the position held by the shooter. Therefore, having a seal permanently in good condition will prevent a portion of liquid contained in the tank from being projected to the outside of the equipment through the hole where the firearms are placed and fire and in the direction of the body of the shooter. Another function of the polyurethane foam cartridge is to reduce the speed of the bullets fired, without causing damage or significant alterations in them.

4 D. Pneumatic and Hydraulic Systems Other technological innovations, incorporated exclusively in the renewed recuperator of standard bullets - RDX3 Pneumatic Actuator; Uses its energy to activate the automated vertical damping processes, allowing the energy transferred to the tank to be released moderately during the shoting process. It also allows the user to adjust the height of the tank to the appropriate position by activating contact switchs, recorded with direction arrows; Up and down. It incorporates a pneumatic shock absorber, which is automatically inflated by introducing air with adequate pressure when the equipment is turned on and whose function is to quickly release the kinetic energy generated by projectiles shot by high speed firearms, which have a certain mass, It will depend on the caliber of the weapons and the cartridges that are used. This happens when the projectiles generates contact with the liquid, which causes great resistance to the passage of the bullets, initiating dramatically the decrease of their inertia, until they completely lose their residual velocity. During the process of shot firearms to obtain the standard bullets, violent horizontal and vertical movements are generated in the tank, so that the shock absorber, in conjunction with the pneumatic actuator, allows the energy of each shot to be released efficiently, Making reciprocity displacements; from top to bottom and front to back, until the tank is returned to its initial position. Hydraulic Receptacle; Manufactured by a transparent polycarbonate tube, which has the main function of checking permanently the level of liquid inside the tank, in addition to relieving the internal pressure during the shoting processes.

5 E. Advantages of the RDX3 The RDX3 chamber is made of a cylindrical stainless steel module, which is assembled by bolting flanges together with high-quality interposed a packing module special polymer that produces an airtight seal. Once the module assembly and the pipe, the total length of the RDX3 is only 6ft (1.83 meters), with a width of 2,03 ft (0,62 meters), which also allows maintenance and transportation easier and more efficient. The automated system RDX3 tank also allows the recovery of the bullets fired it very quickly, estimated time is 1 second for each test bullet, that is; from the moment the gun is fired until the bullet is placed in the basket of recovery. This process is really effective compared to other techniques and equipment that have the same function, but they are more timeconsuming. So that the RDX3, being automated, it is more efficient for institutions required to obtain the test bullets quickly and efficiently when a large amount of firearms that must be subject to forensic examination, the present situation in several countries and it is very common. Therefore, the benefit is also obtained with the streamlining of the activities of forensic experts.

6 Another benefit of RDX3 corresponds to ergonomic, compact and versatile set of machine design, allowing the chamber only occupies an area of 12,92 ft² (1,20 m²), with a height of no more than 6,17 ft (1.88 meters), with a mass of about 1289,7 lb (585 kilograms), including the amount of 62,1gal (235 liters) of liquid. In addition, the chamber for being installed on a cart with industrial bearings, allows the machine to move in turns to 360 over short distances, making it a versatile, easy to carry, maneuver and move equipment. F. Versatility of the RDX3 Unlike large and heavy tanks with water, which are necessarily fixed, the extraordinary versatility of the RDX3 allows the machine to be transported to wherever it is required to perform field work, only the machine is mounted on a trailer specially designed for its operation, which has sufficient autonomy to provide the necessary electrical power for the operation of the RDX3 this by using a gasoline generator installed on the front and outside of the trailer.

7 The structures and mechanisms of the RDX3 is ergonomically adapted to the physical conditions of ordinary humans, allowing its operation is simple and friendly, without people having to make more effort to operate. The machine users only have to comply with safety measures for handling firearms, placing the gun on the centering to adequately correct the position and orientation of the firearm. Thus it is increasing safety for users RDX3, avoiding maximum possible incidents that may be committed by mistake people working in the risky task of shooting firearms for forensic studies. Ergonomics is also presented by height adjustment of the RDX3 by a pneumatic system, which is positioned according to the size and needs of the user, allowing him to carry out the firing in fully upright position with feet resting on floor or platform built into the machine, resulting in a position of comfort for the user, preventing the person has an awkward position or forced. G. Innovations integrated in the RDX3-4th Generation The new equipment; RDX3, incorporates two innovative and versatile systems for the efficient treatment of the filtration of the water contained in the tank, as well as the filtration of smoke generated in the environment, which will be contaminated principally for compounds of burnt and unburnt particles from the explosive primer, the propellant and possibly fragments of the bullet, cartridge case, and the firearm.

8 The first device that is integrated into the tank RDX3-4th Generation corresponds to the water filtration treatment system, where there is a continuous and progressive contamination by the metallic residues that are discharged from the gun shots, which causes a contamination of water, which in the future is harmful to people's health.. Therefore, in the event that water is not treated properly and continuously, it will keep users exposed to the contamination of the shot residues. With the incorporation of the new seal that reduces the speed of bullets in RDX3-4th Generation, made with a special formulation of polyurethane foam, which is a soft and intelligent material, as it tends to rebuild, we completely eliminate the use of any type of gel, which is finally expensive, too dirty and very difficult to filter. Consequently, the unit of RDX3-4th Generation only requires tap water, thereby eliminating the complications of using gels, or any other fluid, which has to be replaced periodically, and because of its degree of contamination, its filtration treatment is very difficult and disposal of metal residues. Our new system includes an independent filtering integrated with the equipment, consisting of an auxiliary hydraulic pump (of small dimensions), two cartridges and special filters of high quality, which eliminate residues up to 0.5 microns (0.5 µm), Therefore it meets the conditions to confine the metallic particles that throw the "Gunshot Residues", or "GSR", Releasing spheroidal, often non-crystalline particles measuring between 0.5 microns (0.5 µm) and 5,0 microns (5.0 µm) of diameter. The remainder are irregularly varied in shape and size, from 1 to more than 100 microns (1-100 µm).

9 Which is ideal for our application, offering great efficiency and spare parts are low cost. This filtration system is incorporated into the RDX3-4th Generation using flexible tubing and high quality connections that allow reliable and efficient operation. The second equipment, which is optional for its acquisition, but highly recommended for use, corresponds to the "Multifunction Ballistic Cart" (MBC), which includes an efficient system of extraction and filtration of smoke contaminated with gunshot residues, additionally a collector of cartridges cases ejected by automated firearms. The versatility of the MBC is mainly integrated by the smoke suction system, filtration and confinement of the gunshot residues for its later elimination, which initially manifests itself as a cloud of gases that is generated in the external environment for each shot that is realized with a firearm to obtain and collect the standard ballistic elements.. Such contaminants, as they are continually breathed by people, promote serious damage to their health over time. That is why, when firing guns in closed environments, it is necessary to eliminate the contaminating fumes with the respective metallic residues, using special devices and filters that are linked with the information that the international standards indicate. Our versatile system corresponds to the special and unique design, as well as the respective manufacture of a cart with displacement, that allows an absolute autonomy of mobility to place it in any place or position that the user requires, even to be employed in other forensic applications.

10 The cart is manufactured in a robust way, using aluminum profiles, plates and covers of special materials of excellent quality. The car has five main functions, which make it more versatile: 1 - It integrates a system of extraction and filtration of the contaminated fumes product of the combustion of the gunpowder, for that a special compartment was designed inside the cart, where a special Housing is incorporated (cartridge holder), where the air filter is incorporated that Have a particle filtration capacity of 0.5 to 2 μm. It also incorporates a centrifugal fan and a tubular articulated arm, which can be placed in the position required by the user and which particularly sucks the fumes that are produced when firing guns. 2 - It integrates a second acoustic compartment where you can install the silent air compressor, oil-free, that supplies air to the RDX3's pneumatic systems, as well as periodically clean the filter of contaminants. 3 The rest of the lower part of the cart is used as a warehouse to store the spare parts of filters and seals that accompany the RDX3. 4 The surface of the cart has a soft polymer cover, which is useful as a work table to place any object, such as firearms, magazine s, cartridges, etc., everything the user wants to have close to his person, in addition to be useful for depositing the ejected cartridge cases by the automated firearms that are fired in the RDX3. 5 The same cart has a strong nylon net, supported by aluminum posts and a top tuft, specially designed to cover an area sufficient to allow the ejected cartridge cases to be stopped by the net and deposited on the cart surface, in such a way that be collected easily.
