Definitions

  • An object of the present invention is to overcome these disadvantages, in order that the apparatus referred to can be compared in its functioning to the operation of the natatorial bladder system of a fish.
  • This system in accordance with the explanations of Giuseppe Colosi, Director of the Zoological Institute of the University of Florence, in its work Marvels of the Sea, makes the tissues and other organs of the fish suitable to resist the pressure at any submarine depth in spite of its natural fragility.
  • the natatorial bladder of the fish in this case, is equivalent to a space full of gas, maintained at an internal pressure perceptibly equal at all times to the pressure of the exterior where it is placed and which, as it is known, can vary in pressure at any moment, according to depth and other factors.
  • FIG. 1 illustrates one possible arrangement of the components of a device for regulating the pressure of a first fluid mass relative to a second fluid mass;
  • FIG. 2 shows on a larger scale and in more detail a control device shown in FIG. 1;
  • FIG. 3 shows another embodiment of part of the device, i.e. the main container, shown in FIG. 1;
  • FIG. 4 shows another embodiment of the main container
  • FIG. 5 shows diagrammatically a two-stage compressor of an alternative type to that forming part of the device shown in FIG. I;
  • FIG. 6 shows diagrammatically a three-stage compressor, which can be used instead of the compressor used in the general assembly of the device according to the invention
  • FIG. 7 shows diagrammatically a known form of multicylinder compressor which may replace the compressor used in the device of FIG. 1;
  • FIG. 8 shows a longitudinal vertical section through a vessel in which a regulating device according to the invention has been installed
  • FIG. 9 shows a modification of the device of FIG. 8.
  • FIG. 10 shows a regulating pendulum for controlling horizontal stability of a vessel fitted with the device of the invention during immersion
  • FIG. 11 shows a half-transverse cross-section of a submarine hull, illustrating another possible installation of the device according to the invention.
  • the regulating device may be used either to control the depth of a submarine equipped with a pressure hull by varying the ratio of gas to water in its ballast tanks or to maintain the air pressure inside a surface vessel which has been adapted for underwater travel but does not have a pressure hull resistant to the external water pressure.
  • the basic components of the device may be located outside the habitable hull 2 of the submarine or the vessel, except for the necessary controls.
  • a two-stage compressor 1 is mounted outside the hull 2, together with its associated electric motor, to which it is drivingly connected in known manner.
  • the compressor 1 comprises a first-stage cylinder 7 and a second-stage cylinder 8.
  • Admission and exhaust valves of the first-stage cylinder 7 are indicated at 3 and 4 respectively, and the corresponding admission and exhaust valves of the second-stage cylinder 8 are indicated at 5 and 6.
  • a safety valve 9 for avoiding excessive overpressure in the cylinder 7 is provided, while an automatic control device 10 for controlling the final pressure established in the first-stage cylinder 7 during operation is also provided.
  • a third line 16 is connected via the exhaust valve 6 of the second-stage cylinder 8 to a series of high pressure bottles l7. 1
  • the regulating tank or container 15 communicates at the bottom with the water outside the vessel, so that this water rises in the container to a level, indicated at 21, corresponding to the position of equilibrium at the particular depth of the submerged submarine.
  • a level indicated at 21, corresponding to the position of equilibrium at the particular depth of the submerged submarine.
  • These variations of level inside the container 15 cause corresponding movement of a float 23.
  • a rod 44 is connected by a rod 44 to one end of a two-armed lever 24, the other end of which is an actuator for a valve 27 and, if required, also for the electric switch 28.
  • Displacement of the float 23 causes the lever 24 to actuate the valve 27 or the electrical switch 28, according to the direction of the movement of the arms of the lever 24.
  • a control member 26, operated from the interior of the hull 2 actuates a small electric motor 25 which is coupled to the lever 24 and also to the rod 44 attached to the float 23. Operation of the motor 25 not only permits the float to rise or fall independently of the level the water has reached inside the container 15, but also reverses the operation of the lever 24, as will be described below. This occurs while the operator maintains the control member 26 in operation, i.e., so as to obtain the desired level inside the container 15, as marked or signalled by corresponding indicators.
  • the valve 27 is located in the line 16 and is connected by another line 43 to the upper part of the container 15, so that actuation of the valve 27 by rising of the float 23 can connect the space 19 in the container 15 with the bottles 17.
  • FIG. 2 shows a longitudinal cross-section of the device 10 for controlling the final pressure (i.e., intended to maintain the latter constant but so as to not exceed the ultimate strength of the compressor walls).
  • the housing of the control device 10 is connected via a tube 29 and a regulating member 30 with the interior of the first-stage cylinder 7, i.e., to the compression chamber of the compressor 1.
  • the tube 29 is divided into branches 29a and 29b, each of which is connected by a gas-tight union to a spring-loaded piston 31 or 32 located in the housing of the device 10.
  • the spring which corresponds to the piston 31 is adjusted to a pressure somewhat lower than the normal pressure in the firststage cylinder, while the spring corresponding to the piston 32 is adjusted to a pressure slightly higher.
  • a double ratchet 33 which has its teeth directed in opposite directions, cooperates with pawls forming one limb of each of two rocker levers 34 and 35.
  • the lever 34 is coupled to the two pistons 31 and 32 and operates to advance the ratchet wheel 33 in an anticlockwise direction, as viewed in FIG.
  • lever 35 is coupled at 36 to a push rod 38 and operates to advance the ratchet wheel 33 in a clockwise direction, as viewed in FIG. 2.
  • the push rod 38 is in turn connected to a two-armed lever which carries a cam follower, so that at each revolution of the cam 37 secured to the crankshaft of the compressor 1, FIG. 1, the shaft 33 carrying the ratchet 33 is rotated.
  • the shaft 33' serves to drive the throttle valve 11, FIG. 1.
  • the lever 34 causes rotation of the shaft 33 by an amount equivalent to one tooth of the ratchet 33, which would be then followed by a similar amount in the opposite direction during the same cycle of the compressor, due to the cam 37 and its cooperating elements 38 and 36 acting on the lever 35, i.e., since the latter is adjusted for an identical movement of one tooth at a time in the opposite direction.
  • the shaft 33 would thus return to its initial position.
  • 39 and 40 indicate limit stops for the strokes of the pistons 31 and 32 respectively, while other adjustable stops 41 and 42 cooperate with the levers 34 and 35.
  • the communicating tube 29 allows the pressures in the firststage cylinder 7 to operate the pistons 31 and 32, and it can be seen that this operation can be obtained by air or gas coming directly from the compression chamber of the cylinder, or by means of any other intermediate fluid, such as oil.
  • this fluid can be principally contained in the regulating member 30, which isclosed at the top and at the bottom by two auxiliary pistons 50 and 51, respectively, the first serving to transmit the pressure from the first-stage cylinder 7 and the second serving to function as a storage or regulation device, for instance, during the filling operation.
  • the float 23 occupies a constant level inside the tank 15, as for instance the level 21, so that the space 19 occupied by gas also contains a constant mass of air or gas which is subject to a pressure equal to that of the exterior water at that depth.
  • the compressor 1 withdraws a constant volume of gas from the space 19, by means of the tube 12, in order to return it, in each cycle of compression, to the same space 19 by means of the tube 14, while the second-stage cylinder remains inactive, and the valve 6 closed, because of the constant pressure of the gas contained in the bottles 17.
  • the submarine has ascended to the surface, the air or gas contained in 19 would have been expanded, because of the lower pressure of the external water, causing the float 23 to descend, for instance to the level 20, making the lever 24 operate the electrical switch 28, in order to actuate the three-way valve 13 and so cause the gas exhausted from the first-stage cylinder 7 to be transferred to the second-stage cylinder 8, instead of returning to the space 19, in order to be compressed and stored in the bottles 17 after going through the exhaust valve 6 and the line 16, until the float 23 finally regains its neutral or original level 21, when the lever 24 no longer operates the switch 28.
  • the lever 24 now operates in the opposite direction to the previous case, ie, it now actuates the valve 27, so as to cause the air or gas coming from the bottles 17 to be sent to the space 19, until the water inside the tank 15 reaches the desired lower level 20 and as indicated by visual signals or indicators in the interior of the habitable hull.
  • the operator manipulates the control 26, so as to leave the components as they were previously, with the exception of the new setting for the float 23 and the corresponding shorter length of the telescopic rod 44, for the actual neutral position of the lever 24.
  • the operator manipulates the control 26 in the opposite direction, so as to cause reverse operation of the small electric motor 25, in order that the telescopic rod 44 becomes extended and so causes the float to occupy a higher position, for instance the level 22; at the same time, the lever 24 acts in the opposite direction to the previouscase, i.e., acting on the switch 28 in order to cause the second-stage cylinder of the compressor to come into action and so cause air or gas to be extracted from the space 19 and to be stored in the bottles 17, for the time during which the level of the water within the tank 15 has not reached the higher level 22, as indicated or signalled in the interior of the habitable hull, at which moment the operator ceases to operate the control 26, thus leaving the components as they were before, with the exception of the new setting for the float 23 and a longer length of the telescopic rod 44, for the actual neutral position of the lever 24.
  • the principal advantage of the device according to the invention lies in that it constitutes a safety element against excessive depths which could result in deformation or even crushing of the habitable hull, because, due to the manner of operation of the compressor 1 in combination with the automatic control device for the final pressure, if the safe limiting depth for the submarine under normal conditions is exceeded, at which it is not possible to obtain a greater degree of throttling at the inlet to the first-stage cylinder of the compressor 1, then the correspondingly greater final pressure inside the cylinder operates the safety valve 9, in such a way that a suitable electrical connection, for instance, would be enough to start any kind of alarm.
  • the device can be arranged to initiate either the introduction of air into the ballast tanks or an adjustment of the depth vanes until the submarine has returned to a lesser depth, without the need of any surveillance on the part of the crew.
  • No less interesting in this aspect of safety during underwater navigation is the possibility of actuating an alarm indicating excessive depth always a little before the limit of safety for the submarine has been reached, by simply graduating the maximum throttle capacity by means of the valve 11, so that this limit is reached a few meters before the admissible maximum depth.
  • Another improvement in safety during underwater navigation includes the addition of a hammer operated by a cam moved by the revolutions of the compressor.
  • This hammer can be arranged to contact a bell or a membrane at one or more points inside or outside the hull of the submarine, in such a way that the sound given by the resultant hammering is a signal for the crew that something is not working properly, so that a return to surface is indicated.
  • the compressor l is installed close to the habitable hull 81, in the case where the hammer is used to hit the hull and where the device has been installed inside one of the ballast tanks of the external structure 82.
  • the compressor 1 can be used during surface navigation to fill the normal bottles of air in such vessels, apart from the bottles 17, by drawing air in directly from the atmosphere through the valve 18, for instance, assuming the latter is independent of the tank 15.
  • the container 15 was described in relation to FIG. 1 as having an opening at the bottom, so as to establish communication with the external water and it is evident that this construction can be varied in many different ways within the scope of the present invention.
  • FIG. 3 for instance, another construction for the tank I5 is illustrated, this time being of a compact and elastic type, in such a way that the space 19 for the gas constitutes the interior of the container.
  • the construction and expansion of the elastic walls 45 subjected in use to the pressure of the external water, would cause corresponding actuation of the rod 44 and its attached elements 24, and 26, in a similar way to that described for the analogous components represented in FIG. 1.
  • the auxiliary rod 46 indicates contraction or expansion of the elastic walls 45, equivalent to the levels 20, 21 and 22 mentioned in connection with the previous embodiment.
  • FIG. 4 Another example of construction of the tank or container 15 is shown in FIG. 4, for those cases in which it is not convenient for the exterior water to pass directly into the tank 15.
  • An auxiliary container 49 and the main container 15 are interconnected and contain a fluid 48 which is a different density and which is immiscible with water.
  • the water enters the auxiliary container 49 through a pipe 47, varying the level in the auxiliary container and thus the level in the main container to actuate the float 23.
  • Piston compressors when used, can be of a very simple construction, such as those having an even multiple of cylinders as shown in FIGS. 5 and 7, particularly when the need is to navigate at a small depth or when dealing with low pressures in the storing of air or gas in the bottles 17, since in such cases these compressors may be even of the single stage type.
  • two or more stages like the one illustrated in FIG. 6.
  • the cylinder 52 operates as described in connection with FIG. 1, the remaining cylinders 53 and 54 serve to till the bottles 17. It is possible, naturally, to interchange the first and second stage cylinders and also combine them in other ways.
  • this type of engine is started by compressed air previously stored in bottles, so that in this example it can be assumed that the filling of such bottles is done by using one or two cylinders of the same engine as compressors, while the other cylinders serve to give power in the normal way.
  • 64 indicates the superstructure, usually found in the stern of this type of vessel, while 21 represents the level of the water when navigating on the surface.
  • this oil tanker has been provided with a habitable chamber 65 in which can be located not only the principal controls for the immersion, but also in which those members of the crew in charge of the engine, etc. can remain when not occupied in the engine compartment 62.
  • a structure in the form of a hollow main mast intended to contain or protect tubes for the admission of air and the exhaust of combustion products to and from, respectively, the propulsion engine.
  • the structure is also for use during navigation when submerged near the surface, in this connection it may house an auxiliary periscope and serve to support a small external observation post, in the top end 67, near the surface or level 22, as shown in FIG. 8.
  • This column or hollow mast 66 can also be used by the crew to leave the vessel when, in an emergency, it would be advisable or convenient not to return it to the surface.
  • the vessel 54 In order to ensure stability during navigation in the submerged condition, the vessel 54 would be provided with depth vanes 68, of known type.
  • the regulating device of FIG. 1 is installed so that the compartment 59 acts as the tank 15 shown in FIG. 1, i.e., after being provided with the corresponding auxiliary elements so that it can function as described in connection with the tank 15.
  • the bow and stern compartments or tanks 55 and 63 are partially filled with oil, so that this floats on the water obtained from the exterior and filling the remainder of such tanks; this ensures the horizontal stability of the vessel, for instance, by transferring oil by means of a circulating pump from one tank to the other and under the control of an automatic device explained later.
  • compartments 56, 57, 58, 60 and 61 are filled completely with oil or in the known way with water, so as to prevent damage to the metal walls because of the pressure of the external water.
  • this may be maintained full of air at a pressure substantially the same as that of the external water, in the usual way; in the first case, this can be easily achieved by connecting the top of the compartment 62 with the top of the central compartment 59.
  • the crew will then not have any trouble in maintaining the pressure of the gases in compartment 59 and other spaces connected therewith, such as the compartment 62, i.e., since this pressure is of a similar value to that of the water in which the vessel is navigating. At the time for returning to the surface, it will be sufficient to drain the tanks or ballast spaces of the water previously admitted at the time of immersion, in order to return the corresponding conditions of flotation.
  • FIG. 9 illustrates another version of the invention, which can be allowed to descend to a greater depth than that usually permitted by the limited length of the hollow mast 66.
  • flexible tubes 69 are connected to a cable 70 which is attached to a floating buoy 71 towed from the same vessel 54 or fitted with its own means of propulsion.
  • These flexible auxiliary tubes 69 allow for the corresponding air admission to and exhaust products from theinternal combustion engine of the submerged vessel, which in this manner can now continue operating at such a greater depth.
  • this device consists essentially of a pendulum 72, as illustrated in FIG. 10, which when the vessel inclines one way or the other acts either on a contact 73 or an opposite contact 74 and so permits the operation of the circulating pump in the correct direction, until the horizontal stability of the vessel is regained.
  • each of the cylinders 77, 78, 79 and 80 so as to take care independently and with all of the accessories, as per FIG. 1, of one or more of the various water-tight compartments of the vessel 54, or of independent groups of them, obtaining greater safety by reason of the independent systems so used.
  • the device 10 may also be regulated with respect to the pressures of combustion or explosion, if this is considered more convenient, while is also evident that the elimination of air from the cylinders could be also effected during the moment when combustion has already been initiated.
  • the same can be said about other possible combinations of the same type, including those concerning the use of the exhaust gases either to fill the bottles 17 or any other water-tight compartments of the vessel 54, if necessary, or in cases where it would be more convenient to descend to a greater depth, during which the clean air retained in the compartment 59 and the remainder could be used for the operation of a small auxiliary engine used only in such exceptional emergencies.
  • the corresponding graduated dose at any successive depth could be obtained by installing the system in such a way that the device in FIG. 1 controls or regulates the helium in circulation, i.e., assuming that the bottles 17 are filled with helium, the fluid gas in the space 19 feeding the breathing mask of the diver, once it has been enriched with oxygen from a bottle provided with a suitable dosing valve operating according to the external water pressure, and while the products resulting from the divers breathing would be returned to the space 19, after being purified or cleaned as necessary.
  • the present invention is also applicable to cases in which the ambient fluid is different from sea water or river water, wherein it can be used as a regulator, as in the cases previously described.
  • An example of such use is a new application on an aircraft or spacecraft, when the ambient or extema] fluid surrounding the craft is of a different density to that of water.
  • the compressor 1 could be replaced by an indicator or current modifier based on a known substance which modifies its dielectric properties when subjected to pressure, in order to act in the usual way on the space 19, in accordance with the other conditions of the ambient atmosphere. Equally, any other known method, either electric or otherwise, could be used instead to carry out analogous functions.
  • the present invention enables naval structures or vehicles of any kind to be operated in different surroundings or atmospheres by means of only slight modifications, while with the same invention it is also possible to adapt trucks, wheeled capsules or tanks to run over the bottom of the sea, by simply adding to their structures the necessary elements or accessories, e.g., as in accordance with FIG. 8.
