Description

The present invention relates to "diving gear" at sea to improve the underwater distance arrangements and achieve various objectives. The threshold of the depths of 200 meters must not be exceeded, at the risk and peril of the scafandriers, the invention overcame its disadvantages for larger funds. The pressure increases according to the descent which is constituted by the mass of the water per liter and multiplied by the difference with the surface to the square centimeter exerted on all the surface of the tire. To calculate this pressure, suppose a square parallelepiped of 1 centimeter by side over 5000 meters long. (or depth). A volume corresponding to a mass of water is obtained: 1 cm x 1 cm x 300 000 cm = 300.000 Cm3 or OM3 300 or 300 Kgs - By experience, driving at high speed with our vehicles, the four wheels inflated to 2 Pressure kilos, pass in the same place several times per second and show the weight of the vehicle either: example 2,000 Kgs: 4,500 Kgs - The tires do not burst ... - Similarly to the image of an airliner , Kraché at sea at 700 meters for 5 years, whose wheels are still inflated - One can confidently build this diving suit that would make multiple services. Being self-contained, compact with compressed air bottles * enclosed inside and on the back of the plunger - Through a hose entering the mouth with rubberized tip for the expiration of the passing Carbon Gas. back ..in.an.adjusted pocket .. --_ By means of a. another hose with a mask fitted with a rubber membrane which is applied as a suction cup, capping the nose for the inspiration of the air coming from compressed air cylinders with pressure reducer. - A gas valve for opening and closing is located inside, aa level of the hips, inclined down - By passing the -main on the belly one can reach easily this tap for the useful purposes. - The arrival piping asau head mask are inserted close to the inner fiber armor and go to eeo the back one for the air bottles - the other the pocket holding. Diving_ consists of a frame of synthetic fiber type "E" or uSu four times stronger than steel and low density 2.4 grams It covers the body with air bottles on the back, coating two main parts : Part I: The Head and the Bust is Om85 Height Om85 al Bust and Chest Base = Om30de 0 In Fiber Parabolo! for the Head of Om Cylinder Fiber Height Cylinder 0100 Retaining Joints: - shoulders - on each side Right and Left - on the bust of the elbows - on the upper arm and forearm parts, cylindrical fiber - By the solid material "Polyrethane" one centimeter thick allowing movement of swimming, walking etc ...

The second 25 minutes under the impulse of the voltage of 12 volts makes open the automatic electric lock. which detaches the belt and weight ballast. The diver climbs to the surface, ignoring the decompression baskets, such as a submersible. Tares weighting on the belt can be relieved one by one by the diver according to his will for a ground clearance and a plumb allowing him to walk easily under water - a slower recovery surface, provided to maintain closed the load shedding belt. Only a few weights can be dropped. This Diving outfit is specially designed for the seabed. - The Autonomy of the bottles being 30 Minutes or 1 Hour is: - Every two seconds: an inspiration followed every two seconds: an expiration is a volume by inspiration of: - 40 milliliters 2 seconds 2 seconds for the expiration in CO 2 4000 "200 x, 2 = 400 seconds or 40 Liters 4000 seconds or 66 Minutes Each bottle has 2U Kilos of pressure the diver can hold for 1 hour The empty Carbon Duty Pouch should have the same volume ie 0 M3 040 To avoid the "bad box" - ie breathe carbon dioxide a door embellished with a spokes wakes up, opening at each expiration and closes immediately after the inspirations.

To descend in depth, with the Diving Suit - Ellerepresente a volume of Air, increased by the Pressure of 1.5 Kgs is = 266.5 Kgs of Air. The weights deducted from the Archimedes' thrust to engulf in the water this mass corresponds to 290 Kgs But on the surface, this weight is not amortized. It would be 0.95 x 290 = 460 Kgs. 0.60 This weight is too important to wear. To better consider and interpret the diving suit, it would be necessary to go down in depth: - either by a bell of descent - or. From the edge of the beaches to penetrate while penetrating towards the open sea. Provided you wear the diver a bottle of Air about 2 kilos and deflate the outfit so that there is no air inside. The opportunity is then offered in depth to slightly inflate the outfit to hold the pressure of 189 Kgs of the mass of the water or following the straws 20 1000 meters 63 Kgs) 2000 meters 126 Kgs) 3000 meters .... 189 Kgs Either Calculate the corresponding pressure as a function of the calculation at the square minus square: the Peussededrchimedes. 25 Adjusted according to distances.

REVENDICATIONS1. Diving outfit in pneumatic inflated Air with 1.5 Kg of Pressure which rises to the surface after the allotted time by releasing the belt of Tare, or in case of discomfort of the diver, without taking into account the baskets of decompression, by its design hermetic, like a submersible. Taken as an example with a depth of 3000 meters: the air volume stored in the density of 191 kg is added with a pressure of 1.5 kg or: 191 x 1.5 - 286.5 kg - With the load weights.77.3 K 10 - With the weight of the Pressure 189 K 266.3 K The Difference = 286.5 266.3 = 20.2 Kgs allows the diver to climb without the load shedding belt. Extra weights are recommended to keep a steady foot on the bottom of the water. - Passed a time of 20 minutes - alarm that warns - Passed a time of 25 minutes - 2nd Ringtone - - take refuge in a bell of descent with the tares 4) LC - go up to the surface and ballast the belt of tare. 20 With this outfit you can sink from the beaches to the bottom of the sea, By deflating the holding of its Air and carry a compressed bottle of Air allowing it to inflate the outfit under water - to agree to pressures. A table can be constituted. 25 - The articulations have pockets in inflated chambers to 0.6 Kgs filling the cavities around them. These independent chambers are attached to the back by self-adhesive pressure all around, with internal valves (such as Messiahs of footballs) 30 - the Hose Connection between Chamber passes over the pockets and allows inflation in full. This inflation transition at these places in pressure drop of 0.6 against 1.5 Kgs can relieve rotational movements.
