FIELD OF INVENTION
The Mechanical device to change the potential energy of a hydro system, relates to the fields of Physics and Hydrostatics.
BACKGROUND OF THE INVENTION
The subject invention is meant to change the potential energy of a hydro system, making use of buoyant force and gravitational force, induced in a liquid column through the assembly of mechanical components as mentioned in detail hereunder.
The change in potential energy takes place due to a law of hydrostatics according to which " THE MAGNITUDE OF POTENTIAL ENERGY, INDUCED IN A LIQUID COLUMN BY THE COUPLE, FORMED OF A BUOYANT FORCE AND A GRAVITATIONAL FORCE, WHICH ARE EXACTLY EQUAL TO EACH OTHER, REMAINS SAME THROUGHOUT THE COLUMN, SO LONG THE DISTANCE BETWEEN THE POINTS OF APPLICATION OF BOTH THE FORCES, MEASURED FROM THE CENTRE OF GRAVITY OF THE COLUMN, REMAINS SAME". The change in distance between the points of application of buoyant and gravitational forces brings the change in potential energy of the column in which such a system is placed and therefore, provides rotational movement to the column.
Hitherto all the inventions relating to movements with in liquid, have been based on the principle of buoyancy, where the liquid chamber is kept static and the air filled chambers move up or down to impart motions. The drawback with these inventions is that once the air chamber moves up in the liquid due to the force of buoyancy, same force is then used to bring the chamber back to the floor to make it operative again. Or alternatively the liquid has to be drained out in order to push the chamber back to the floor. There are no inventions available which use the unique combination of buoyant force and gravitation force based on the above referred hydrostatic law.
Also no such invention is available, which provides a rotational movement to a liquid column by using the distances between buoyant & gravitational forces internally. Hence no reference is being given of the past inventions. The unique feature of this invention is the way, distance is induced between the application points of two forces by maneuvering the components installed within the liquid column.

PARTS OF THE MACHINE
1 A column filled with liquid, marked as (1)
2 Two bodies which are lighter than the liquid in which these are immersed, marked as (2) & (2A)
3 Two solid weights marked as (3 & 3A)
4 A support rod to hold the bodies 2 & 2 A, individually, marked as (4)
5 An axle around which the liquid chamber rotates marked as (5)
6 Pivot points of the bodies around which they are rotated marked as (6)
DETAILED DESCRIPTION BASED ON DRAWINGS
In the initial stage (fig 1) two bodies (2) & (2A) are positioned within the liquid column (1) on either side of the axle (5) with the help of the support rod (4) in a slanted position, having the same angle of inclination. The two solid weights (3 & 3A)) placed on the bodies (2) & (2A) individually, are facing outwards from the centre of the liquid column. In such a situation the liquid column is in balanced mode because both the bodies have their points of application of buoyant forces and points of application of gravitational forces at equidistance from the central axle (5) of the liquid column (1). To induce change in potential energy of the system, body (2) in the upper end A of the Liquid column (1) is so rotated downward around its pivot (6) by any normal means, that it becomes horizontally parallel to the centre axle (5) of the liquid column (fig 2). In such a situation the distance between points of application of buoyant force and gravitational.force in the body (2) increases from each other as compared to the earlier position when body (2) was in slanted position, (fig 3,). This is shown as difference between Dl & D2 in the figure on page 3, as measured from the centre of gravity of (2) & (3) . Now according to above mentioned law of hydrostatics, the potential energy in upper end of liquid column gets increased and consequently the liquid column (1) rotates around its axle (5) due to higher potential energy and the situation becomes as shown in figure 4.
The two bodies 2 & 2A are now in opposite ends of the liquid column than they were at the starting position. Body (2) is now in lower end and body (2A) is upper end of liquid column. To once again achieve higher potential energy in the upper end of the column, body (2A) which is in slanted
position, is rotated by any normal means around its pivot (6) in such a fashion that it becomes horizontally parallel to the central axle, resulting into increased distance between points of applications of buoyant force and gravitational force, hence higher potential energy. At the same time body (2) in the lower end is also rotated around its pivot (6) so that it regains its slanted position (fig 5) thereby decreasing the distance between points of application of buoyant force and gravitational force, hence reduced potential energy in the lower end of the column. As the upper end has now higher potential energy than the lower end, the column again rotates and circle thus gets repeated.
