Description

Known devices for demonstrating ;: vani laws. Pascal, relating to the pressure of the liquid on the bottom and the walls of the srsud, is well-connected and has a bottom wall that is balanced by a weight.

In the proposed devices, the movable bottom and each of the movable walls are connected by blocks, which are thrown over the ground and provided with cargoes, by an employee (1 and for balancing hydrostatic pressure).

In the drawing, Fig. 1, 1 depicts a vertical section of an instrument for demonstrating the properties of liquids; FIG. modification of the device, also in vertical section. The instrument (Fig. 1) consists of a fluid-filled open top. a vessel with a quadrangular, cylindrical, or other shape in cross section, in which it is fixed, not connected to its machines, a sliding horizontal board O, suspended from threads ff (thin steel wires), thrown over blocks (reinforced in the walls of the device), and attached to the vertical, - which can move (with minimal friction) in the horizontal lateral patches T; amount;

(436).,

The areas of pistons l are equal to the area of the axle (bottom). From being drawn into the inside of the device by the action of the weight of the bottom d and the liquid, the pistons are kept attached to them from the outside by threads AND thrown through the outer blocks 6 with weights G on them. V Modification of the device (Fig. 2) is characterized in that it has at the bottom a broadened part P (the method of connecting it with the upper part C of the device is not shown in the drawing), closed from the bottom with a movable bottom — d, illuminated on threads N and more than two, for example, four) attached to the ring (if vessel C

jji its lower P have a cylindrical shape) horizontal piston n, located in the gap

between vessel C and its .Ushire part of P and kept from lowering down with the help of attached

outside the threads N, thrown over the blocks b with the loads G suspended on them,

 The effect of both instrument variations is as follows. The instruments of FIG. 1 and 2 are horizontal planes d, located directly below the vertical columns of liquid above them in vessels C,

they are replaced at the bottom and, therefore, should serve as the support area of the l: liquid, as a weighty body. But since these planes are easily movable and external support, it seemed to be1, they should descend under the force, the weight of the chip is under this plane at the top of the liquid column. In fact, the following will happen FIG. 1 force forcing the bottom of the op ;; skat down ,, will be equal to the weight of the fluid in the volume between the bottom d and its level at the height of the lower edge of the nozzles V (line), av in the device according to FIG. 2 - the weight of the vertical liquid column, the base of which is the bottom, and the apex is at the height of the lower CTppp iH piston (following the first and second Pascal laws). If the d plane went down With a force, the proportional weight of the entire vertical liquid column above the plane, moreover, the friction between the walls, the instruments and their moving parts would require 5 liters: g, and the weight of all the liquid in the vessels C if, for example, 100 lg, they could have suspended the loads of approximately 90 kg .. from the bottom of the pistons and would lift them to a certain height (the liquid level in the vessel would have remained without merit during application).

In this case, the corresponding potential energy of the system would appear in the form of lifting the cargo height, but without an equivalent reduction of the potential energy of the other system, which is liquid in the vessel as a liquid mass, lowering 111-15 sec. times (depending on the capacity of Cs-ships - C) is less than the mass of lifted loads. But i-aiK as such a result, due to the aforementioned reasons of nevrymzhzhen, the devices give an impressive experimental proof of the impossibility of perpetual motion machines on the principle of using force of gravity.

The subject matter of the invention.
