Abstract

The invention relates to a device comprising a plurality of groups of movable forearms which rotate about a fixed axis. Arms holding masses (11) rotate at the extremity of said forearms. The arms (8), driven by gears or electric motors, effect the number of revolution per second than the forearms (15). The arms rotate in a direction opposite to the rotation direction of the forearms and one half of the forearms rotates in a direction opposite to that of the other half. Thus, at each rotation, the arms and the masses at the extremities thereof are periodically in the extension of the forearms while other arms are superposed to the forearms with their masses being behind the fixed axis. These synchronized differential motions generate forces which may be used essentially to displace vehicles without bearing on air, water or the ground, and to convert thermal energy into mechanical energy.

Description

DIFFERENTIAL CENTRIFUGAL FORCE DEVICE

The present invention relates to an autonomous motor device and thermo-mechanical converter with differential centrifugal force. This device allows, when it is supplied with energy, to move in space the vehicle which serves as a support, with or without load and without bearing on the air or on anything of material. This device also makes it possible, in a mounting variant of its constituent parts, to produce mechanical energy from the ambient thermal radiation. Both variants. motor and converter, which can be mounted on the same vehicle.

Apart from the cunning. all known motor devices require, to move the vehicle containing them. a material support; whether it's solid ground or gaseous air. The so-called "anti-gravitational" machines, with the exception of rocket engines which eject gases, have never risen in space from Earth. With regard to the known attempts of driving wheels associating masses with arms of l sink, integral with the axis. and made longer on one side of the axis than the other. they have a handicap which consists in this need to raise more masses on the short side than on the long side, which prevents the release of a sufficiently different centrifugal force between two diametrically opposite masses.

The device according to the invention allows oe remedy. as regards the differential centrifugal force. to the aforementioned drawback. 11 is built up. in its simplest version, two axes, one of which is fixed and the other mobile. A forearm of any shape and material but of rinsed length. is drilled with a hole at one of its ends to be able to turn. in the plane of its length, around the fixed axis. A second hole is made. at the other end of the forearm. to allow the attachment of the second axis. perpendicular to the plane of rotation of the forearm.

This second axis rotates at the same time as the forearm, but it is integral with the latter and does not rotate itself relative to the forearm. On the second axis, attached to the end of the forearm. rotates, in the same plane as the forearm and with respect to this forearm, the actual arm of the device. This arm is, like the forearm, of any shape and material but rigid enough to withstand significant centrifugal forces. The arm length is

always slightly less than the length of

the forearm to allow the device to operate. The arm is pierced with two holes; one to

each extremity. One of these holes allows the arm to rotate around the movable axis located at the end of

the forearm. The second arm hole is used for

fixing of the mass which will produce, when the device is set in motion, the differential driving centrifugal force and, in a particular configuration. the transformation of radiant energy into energy

mechanical. The arm and forearm do not rotate at the same speed, but at the same frequency. That is to say that when the forearm has made a full turn around the fixed axis, the arm has also made a full turn around the movable axis. The arm and forearm always rotate in opposite directions to each other. When the device consumes energy. that is to say when he moves his support for example. The forearm is set in motion by a conventional motor. thermal or electric. This basic version is illustrated in Figures 1,2,3 and 4 in these figures. for the clarity of the drawing. the organs are shown in very schematic sections. The support (1) of the fixed axis (2) is a U-shaped bracket of which only one branch of the U is shown. The fixed axis (2) is integral with the support bracket and a circular track (3) centered on this fixed axis. A wheel (4), integral with the forearm (5), by means of an axis (6) movable in the forearm. rotates, by friction, on the fixed circular track (3). The wheel (4) has the same outside diameter as the fixed circular track (3) and drives. also by friction but in the opposite direction, another wheel (7) integral with the arm (8) and therefore rotating, like the arm (8) around the axis

mobile (9). All the wheels (3,4 and 7) have the same diameter so that the arm (8) and the forearm (5) each perform the same number of revolutions per second. The friction drive system between the wheels can be replaced. in other variants of the invention by a gear or pulley drive, when the forearm is very long for example and it is less expensive to provide pulleys of standard manufacture. It is only necessary that the movable wheel (4) has the same diameter as the wheel or the fixed track (3). Thus the axis (6) can carry, in other variants of the invention another pulley whose diameter will correspond to the diameter of the pulley (7); and it will synchronously drive this pulley (7) in friction, by friction, by gears, by belt, by chain or by an electrical connection device known as an electric shaft. The connection of the forearm to a conventional heat or electric motor is ensured by a fourth pulley (10) integral with the forearm (5) and represented, in the figures, by a dotted circle inside of the circular track formed by the fixed pulley (3). This pulley (10), forearm drive. which can be an electric motor rotor, is also the pulley for driving use, when the invented device supplies energy instead of absorbing it.

The mass (1 1). at the end of the arm (8) is represented by a small black cylinder. Figure 1 shows the position of the arm (8) and the forearm (5) when the device is started: they are superimposed, the arm folded in front of the forearm in the low position below the 'fixed axis (2). This figure 1 clearly shows that the arm (8) cannot be as long as the forearm (5). because, at the end of the arm, the mass (11) would strike the fixed axis (2). Figure 2 shows the respective positions of the arm and forearm after a quarter turn of the assembly. The centrifugal force, developed by the arm (8) and forearm (5) and mass (11) assembly. at

increased from the starting position illustrated in Figure 1 and it is always directed upwards of the figures from the start of the movement.

Figure 3 shows the respective positions of the arm (8) and the forearm (5) after half a turn of the assembly. The arm and forearm are in the

extension of each other. The mass (11) reaches its maximum distance from the fixed axis (3) and the centrifugal force is maximum. FIG. 4 represents the respective positions of the arm (8) and the forearm (5) when this assembly has made three-quarters of a turn. In this figure 4. the mass (11) occupies with respect to the axis. a position symmetrical to the position it occupied in FIG. 2. without changing the direction of the centrifugal force: but by decreasing it compared to FIG. 3. The direction of rotation of the device is indicated, in all the figures, by curved arrows. The direction of the differential center force is indicated by straight arrows. Despite a constant sense of differential centrifugal force obtained by this first version of the invented device. variations. sometimes increasing and sometimes decreasing the centrifugal force. cause a faulty operation of the assembly which moves in space by spinning on itself, in the direction of rotation of the forearm. To overcome this faulty operation, a preferred version of the invention consists in associating, face to face, two elongated forearms, as shown in FIG. 5 which is a section parallel to the fixed axis (2). These elongated forearms (15) have a length doubled compared to those of the previous figures. This length of forearm is indeed doubled, to be able to drill a hole in the center and a hole at each end. Thus these new elongated forearms will each be provided with two arms (8); an arm (8) at each end of each elongated forearm (15). These arms (8) have a length slightly less than half the length of the elongated forearm (15) for the reason already indicated. In addition to the pulleys (3, 4, 7 and 10). a new pulley or a sprocket of gall chain (16) is fixed on the other arm (8) of each elongated forearm (15). This second arm (8) rotates, with its pulley (16) on a second movable axis (9). The central hole of the elongated shafts (15) is crossed by the fixed axis (2) and. during operation of the

device. an endless belt or chain (17) joins the two sprockets (7) and (16). which have the same number of teeth or the same diameter so that they make the same number of revolutions per second and so that they have. relative to the elongated forearm (15) of the synchronized positions. So. for example, when one of the arms (8) is in the extension of the elongated forearm (15). the other arm (8) is folded exactly above the part of this forearm (15) which is below the fixed axis (2). In this way. it is not necessary to provide a second wheel or intermediate gear (4): but it is then necessary to provide a static balancing mass (18) on the part of the elongated shaft (15) which does not carry the intermediate pulley (4) and as shown in figure 5. All the masses fixed on the arms are identical. The elongated forearms (15) which face each other rotate in opposite directions to one another. One of the forearms (15) is driven by a conventional motor and through the pulley (10). He in turn trains. but in the opposite direction, the second elongated forearm (15) either via a conventional system

electromagnetic servo control, either by a double angle gear or friction gear like

shown in Figure 5. In this figure, each of the elongated forearms (15) is made integral with one of the axial gears (12) of the double bevel gear. These axial pinions (12) fixed on the elongated forearms (15) face.depart on either side of the intermediate pinions (13) perpendicular to the fixed axis (2). The intermediate gears (13) face each other. on either side of the fixed axis (2). and turn

freely on an auxiliary axis (14) perpendicular to the fixed axis (2). The two perpendicular axes. (2) and (14) are both fixed because they are rigidly connected to each other and to the support (1). The fixed axis (2) has depending on the possibility of turning. relative to the support (1) and under the effect of a conventional non-reversible mechanical control. for example tangent wheel and worm. to be able to direct the production of differential centrifugal force in the chosen direction. As shown in Figure 5, when the arms (8) of the elongated forearms (15) are aligned on these forearms. It still remains, in this second version of the device

invented. a risk of tilting the support in one direction or the other of the movements of the forearms.

To make the operation of the device even more stable, in all operating conditions, a

third variant of the invented device consists in fixing, on each of the elongated forearms (15), which

rotate in opposite directions. one or more others

sets of elongated forearms (15) and arms (8).

The elongated forearms thus superimposed and crossed are regularly offset, with respect to each other, by 90 ° when there are two or by 60 ° when. for example, there are three. of each side of the double bevel gear. Thus the differential and uni-directional centrifugal force, produced by the device, manifests itself smoothly and without risk of tilting of the support in a direction different from that of the direction chosen relative to the support. To link with certainty the movements of the arms between them and ensure the phase shift of their reverse movements because compared to two of the forearms, the pinions (16) of the arms (8) of each group of elongated forearms (15). on each side of the double angle gear, are joined together and to the drive pinion (7) by a belt or a galled chain. or by an electromagnetic servo. Figure 6 shows such an arrangement with two forearms (15) extensions.on each side of the double angle gear. These elongated forearms (15) are offset from each other by 90º and the operation of their respective arms does the same so that. at each quarter turn, the positions of the arms (8) are those shown in this figure 6. The arms (8) which face each other on either side of the double angle gear, always occupy the same position at each quarter turn: at this moment, when we look at them, perpendicular to the fixed axis (2), they overlap and this is why Figure 6, which is a schematic view perpendicular to the fixed axis ( 2), shows only four arms. Between the quarter turns, the positions of the eight arms are offset but symmetrical. The differential centrifugal force produced by the invented device is a function of the dimensions of the arms, forearms, the number and size of the masses, all identical. It is also and above all a function of the frequency of rotation of the assembly.

The force produced by each mass varies during rotation. of {F = m. ω ² · (R + R ')} to (F = m · ω ² · R). R 'representing half the length of the elongated forearm, and R representing the length of the arm. A high frequency of rotation makes it possible to reduce the dimensions of the device and the importance of the masses. The thermo-mechanical generator or converter variant with differential centrifugal force. which is also the fourth variant of the device. is illustrated by FIG. 7. This last variant uses the same elements as the third variant, illustrated by FIG. 6. But in this FIG. 7, the arms (8) of the elongated avantoras (15) which face each other quarter of turn and turn in opposite directions, two by two, on each side of the double angle gear. are no longer superimposed at any time during the trip: unlike what happened in the third variant. In this figure 7. during the reverse movement of the assemblies, the fictitious lines which go from the movable axes (9) to

masses (11) are in opposite directions. on either side of the double bevel gear, and the forces

differential centrifuges are also opposite to the right and left of the figure. If a driving force, external to the device, acts on the pulley (10) and if the two differential centrifugal forces are equal. the support (1) cannot be moved.

The low tilting torque, which manifests itself

perpendicular to the length of the fixed axis (2) and which results from the non-zero distance separating, on the fixed axis, the forearms rotating in opposite directions, is canceled by placing on this fixed axis (2), and in the direction of the length of this axis, two devices similar to that which has just been described. This fifth variant balances all the lateral rotation couples, because, following the last forearms (15) of the first device which rotate in a certain direction on the fixed axis (2). are placed the forearms (15) of the second device which rotate in the same direction. Thus the extreme forearm groups (15) which rotate in the same direction. but who belong to two

different devices. are separated by two other central forearm groups (15) which both rotate in opposite directions to the direction of rotation of the extreme forearm groups (15) and which also belong to two different devices. One of these devices can be an autonomous motor device and the other device a thermo-mechanical converter like the one shown in FIG. 7. In this figure 7. two circles in broken lines represent. when the support remains fixed, the figures described by the masses in space at each complete turn of the elongated forearms (15).

The vertical lines in dashed lines (19) represent both the direction of the force of attraction of the gravitational field and the separation of the entry and exit zones of the field. Without movement of the entire system, similar masses thus positioned in the figure cannot move; that is to say, initiate a descent. because, due to their connection with the elongated forearms (15) they would cause an equivalent rise in the forearm and therefore their own rise. By cons, if the forearms (15) are set in motion. in the direction of the curved arrows, the device will continue to rotate because the moment of the masses entering the field is constantly greater than the moment of the masses leaving it. Indeed, during the rotation of the device and due to the centrifugal force which links arms and forearms, the moment of the masses (11) is no longer the product of each mass (11) by the length of the arm (8 ). but, as a function of the rotational movements of the assemblies, the product of each mass (11) by the length of the arm progressively increased by half the length of the forearm and then progressively decreased by the same length. This is shown by the component force diagrams drawn at the top of figure 7 on the right, left and center. The horizontal arrows represent the local centrifugal force. The vertical arrows

represent the moments of local attraction forces exerted on the masses (11) by the gravitational field. The results of these moments are unequal on either side of the lines (19) which each separate the area where the masses (11) enter the field. From the area where the masses leave the field. This imbalance maintains the rotation of the device: rotation initially initiated by an action external to the device and by

through the pulley (10). It is the effect of differential centrifugal force; for short: F.C.D. The action of radiation, of all wavelengths on the masses, always results in the end, by a heating of the bodies. The masses therefore capture the radiation and heat up. To warm a cold body. just shake it in the air and

warming, this body expands. Conversely, a body that loses energy contracts and therefore cools.

A body in motion, under the effect of an acceleration, or which enters a field (which is equivalent to an acceleration produced by the force of the field), is

contracts all the more as the acceleration is strong. It therefore releases, as a result, a potential energy which becomes visible only at deceleration, by shock, friction or when the moving mass provides work. Conversely, a body which leaves a field expands and absorbs energy since it is necessary to overcome a certain resistance to initiate the movement. In the current practice of a wheel with a mass concentrated at a point of your periphery: when the mass passes from the high position to the low position, it provides energy by pressing this mass on the radius which joins the mass to the axis. Conversely, when the mass passes from the low position to the high position. it absorbs energy by pulling this mass on the radius which joins the mass to the axis. Energy passes mechanically, through bodies in motion through these simple, elementary phenomena.

fundamental and which are called: compression, traction, torsion. So that the mass which leaves the field does not absorb, by means of the traction which it exerts on the radius of the wheel. all the energy it had given, by compression, when entering the field. a special assembly must cut the mechanical traction chain which goes from the mass to the center of the wheel passing through the spoke. It is one of these theoretical arrangements that the invented device achieves.

By examining the force composition diagrams drawn in Figure 7. we see that the diagrams, in the center of the figure. present a compression result for the masses (11) which leave the field, and with respect to the fixed axes (2). Now in normality and following the example cited above of a simple wheel with a mass at the periphery, the result. relative to the center of the wheel, of a mass which goes up from bottom to top. is always a pulling force. The device invented. due to the variability in the length of the lever arms, allows, without modifying the mass ratios on either side of the fixed axis (2). to go up a mass while preventing this mass from taking from the mechanical system which raised it as much energy as it supplied to it when entering the field. The mass (11) which contracted by losing energy and therefore by cooling on the descent will have to. to expand and heat up on the ascent. borrow. by conduction. convection or radiation. energy to its immediate environment and more specifically to the air in which the device moves. When the field in which the device is moving is the gravitational field, the frequency of rotation of the device is not very great and the cooling of the masses (11) is slight. This cooling is even less marked when the device is running at no load and does not supply energy for outdoor use. Like liquids which vaporize at room temperature and cool all the more as their expansion is accompanied by a

production of work by pressing a piston in a cylinder for example, the cooling of the mass (11) which enters a field, is all the more marked as the invented device provides its maximum energy at the expense of the speed which decreases . Empty, for one length. a given number of arms, a quantity of mass and a nature of field, there is a speed limit

corresponding. If the load becomes too great, the device stops. The maximum energy that can be produced depends on the lengths of the arms (8), the forearms (15), the size of the masses (11) and the nature of the field. To produce more energy without having too large arms and too large masses. it is necessary to use high intensity fields. This is what is achieved in the sixth variant of the invented device where the maεsesdl J are magnets or electromagnets. In this variant six, the device is similar to that of variant four. except with regard to the masses (11) which are movable magnets so that their magnetic axes are always parallel to the

direction or magnetic field produced by a hollow coil or by a large fixed magnet secured to the support. In Figure 7 the hollow coil is represented by a rectangle (20). The device invented. in this variant six, is placed at the inlet of the hollow coil so that the movable magnets (11), during their descent.

always encounter an increasing magnetic field. An arrow on the masses (11) represents the mobility of the magnets. Such a device is therefore. or a transport unit. or a generator of mechanical force.

But the simple balancing of the cent r i f u ge s differential forces on either side of the fixed axis (2). with groups of arms (8) and forearms (15) in opposite orientation, is not enough for the device to provide appreciable work. for the acceleration of the masses, in the direction of force, is immediately followed by a deceleration of the same progressiveness. Besides the different position of the arms (8) and forearms (15), the invented device. in its variants intended for the conversion of thermal energy into mechanical energy. also has additional organs and that's what the

figure 7. In this figure 7. there is no mass (11) at the end of the arms (8) which are below the horizontal line joining the arms (8) which are, at the same time, in the extension or superimposed on their forearms (15). In variants. of the device with differential centrifugal force, intended for the conversion of thermal energy into mechanical energy, the masses (11) must be capable of being detached from the ends of the arms where they are temporarily placed. Their fixation. at the end of the arms (8). must be removable.

The fastening systems are conventional systems which can, for example, be. mobile bowls or pneumatic or magnetic suction cups.

Figure 8 shows a fixing by cuvettes

pivoting (21); the mass (11) being in the bowl.

The purpose of this movable attachment being to allow the mass (11) to leave the end of the arm (8), when the latter is in the extension of the forearm (15). At the moment the acceleration of the mass (11). located at the end of this arm, is maximum. The mass (11) must then be transferred to the periphery of a simple drum pulley (25). This drum pulley (25) rotates on an axis (22) secured to the support (1) common to the entire device, but it is mechanically connected to one of the forearm groups (15) which rotate in one direction or in the other depending on whether it is placed to the right or left of the

device. so as to rotate itself in the same direction and has the same frequency of rotation as the forearm group to which it is connected. Connections

conventional mechanics between the forearm and the pulley drum (25) are not shown in FIG. 7 so as not to overload the drawing. There are two pouliestambour (25) per energy converter device, except in variant five where there are normally four

pulleys (25) since there are four groups of forearms (15). Each drum pulley (25) is placed between two forearm groups (15) which rotate in opposite directions as shown in FIG. 8. At the periphery of each drum pulley (25) there are, regularly spaced, as many of pivoting bowls that there are arms which, in a single system, rotate in the same direction. When an arm (8) is in the extension of its forearm (15). it is also perpendicular to the direction of the field of gravitation or of the magnetic field and it is at this time that the rixes cams. integral with the support (1) and not shown, for ιa ciarté αes drawings of

rigures 7 and 8. act on the fins (23) of all the cups (21) to counteract the groove of the return springs (24). The positions of the bowls are. then.theIles shown in ia figure 8.The mass (11). which is at the end of the arm (8). in the extension of the forearm (15) can roll. falling slightly. on the gangway the fixed (26), and slide into the bowl 21) which is opposite on the periphery of the drum. At the same time, the

masselll) which is in another bowl. diametra 1 opposite, at the periphery of the drum (25). can roll

similarly, by borrowing another fixed gangway (26) towards the bowl (21) of the arm (8) folded over its forearm (15). The masses (11) thus pass, with the minimum of energy expended. from a system of arms which rotate in one direction, to the system of arms which rotate in opposite directions and carry out, in a simple manner, their continuous transfer, from the maximum energy position to the starting energy position of acceleration, without changing the direction of the central force. Indeed. the operating condition of the device converting thermal energy into mechanical energy being that the contraction of the masses never stops: that is to say that not only does the acceleration of a mass never become more than the centrifugal force which is exerted on a mass (11) is always greater, when the device is started, to the force of attraction of the field in which it is immersed: otherwise the device stops rotating. The radius of the drum pulleys (25. is substantially equal to the length of the arms (8): it is therefore substantially half the radius of the system of accelerated masses which, for its part, is equal to the length of an arm (8) increased by half the length of the forearm. Because of the conservation of the moment

kinetic. a mass accelerated to the maximum by the arm (8) and forearm (15) system and which falls on the periphery of the drum pulley (25 (will tend to maintain its angular momentum and accelerate the drum pulley (25) until '' double the frequency of rotation of the arm and forearm system on which the mass (11) was

originally linked. It is this phenomenon that allows

acceleration of the device to normal speed and from an external force applied to the

pulley (10) and sufficient to start, even slowly, the invented device. Indeed the angular momentum is equal to Jω. And J, moment of inertia being equal to mR ² , the smallest radius of the drum pulley (25) causes its

maximum acceleration when mass is transferred to it. Maximum acceleration compatible with the energy losses due to the work provided outside and the heating by friction inside the device itself.

When the device converting thermal energy into mechanical energy operates, it behaves near the ground and from the point of view of energy production. like a satellite attracted by a planet but which does not strike this planet because its central force is sutfisammant important. The satellite more or less bypasses the planet and uses the energy acquired during the approach to move away by ricocheting on other planets or to return sooner or earlier towards the same planet. The analog of the passage from the perigee to the apogee. in the invented system being the transfer of masses (ll) of maximum centrifugal acceleration (perigee). basic centrifugal acceleration (apogee), via the drum pulleys (25).
