The invention relates to device with 2 methods to produce electricity, hydrogen and oxygen for free. First method is to prepare hydrogen and oxygen in a cylinder under sea surface, closed at the top and opened at the bottom. Gas is to be stored in tank above sea surface, this tank is supposed to be filled with water and at its top is placed a water -based turbine. For the turbine to work, the gas flow rate at the sea bottom shall be equal to water flow rate at the turbine, so that compression remains stable at the tank and electricity is to be generated at the same rate till water at the tank runs out, with the turbine and gas flow source at sea bottom shutting down automatically. Thus, the tank would contain gas compressed by sea compression power, and this is the first usage of the gas. Then, gas is used for the second time through pushing gas into a tank totally filled with water, the size of which equals the size of the previous tank multiplied by value of gas compression at sea bottom at its top is placed a water -based turbine. For the turbine to work,.Then, electricity is to be generated till compression loses its power and the turbine shuts down automatically. The second method is to use gas compression produced by electrical analysis, on condition that electrical analysis is to be conducted in a space completely filled with, so that the generated gas can only be raised from a tight location with a tiny amount and huge compression such compression is introduced into a tank filled with water, at the top of which exists a turbine run by water power to generate electricity till compression declines. In both cases, hydrogen and oxygen are filled individually. Electricity amount produced by both methods is greater than operation power, so that part of the generated power is used to run the device and the rest can be used in anything else.

The invention relates to a device comprising a reel around which a cable is wound. One end of the cable is tied to a floating body (buoy) and the other end is connected to a spring or ballast, or to both. The reel is attached to a shaft that acts as the axle, which is rotated by the reel. The axle is connected at both ends to two electricity generators by a special connector. All of the components are attached to a base that floats on the surface of the water and that is tied to the seabed or to suitable ballast (or similar). When the buoy rises under the effect of an incoming wave, pulling the cable, which makes the reel rotate, and also when the buoy descends under the effect of the spring or the counter ballast, the special connector rotates the generator, thereby generating energy. The device comprises: points for attachment to the seabed; a cable or other means of attachment; attachment points; a base; carriers; an electricity generator; a special connector for transferring movement; an axle; bearings; a reel; a cable wound around the reel; a buoy; and counter ballast.

The present invention relate to a smart license plate. The smart license plate helps to reduce car theft accidents because it can recognize the real owner, and once a thief ride it numbers on LED disappear so the driver is potential suspect of theft. In such case police officer can trace the car easily. The ordinary license plate could be replaced with another one, so the car cannot be traced which harden the mission of the police.

The invention relates to a novel vehicle designed to collect and transport household waste and capable of simply and easily replacing a full rubbish bin with an empty bin. The method consists first in introducing the rubbish bin at the centre of the vehicle, a telescopic loader raising the bin, which is disposed on a metal mat driven by means of a hydraulic motor; emptying the bin in the yard of the recycling centre and sorting the contents thereof by means of a hydraulic device which is disposed at the recycling centre and turns over the waste, before a digger conveys the rubbish, depositing it on a special sorting path; and separating it into solid waste, organic matter and material likely to be used in the domain of alternative energy.

The invention concerns a dynamic accumulator which is principally used to suppress pressure and flow variations in lines conveying hydraulic energy or fluids. The accumulator uses a mass-spring system in order to attain large-scale dynamic displacement, and consequently to improve the pressurized fluid storage capacity as compared with displacement resulting from the corresponding static pressure. To that end, the adjustment of the resonance frequency of the accumulator is adapted to the speeds at which the pressure and flow vary on the conveying lines. This accumulator both enables the variations to be efficiently suppressed, and it may thus be used in a wide range of applications in new types of pump, and the digital technique of pulse width modulation to be used in the high-precision control of hydraulic actuators. The invention also enables profitability in terms of production and operation to be improved, and the performance and efficiency of the system to be enhanced.

Hydraulic distributors are economical valves in which the resistance to the flow of pressurized oil is minimal; however, they are slow and cannot be controlled rapidly and accurately. In contrast, servo valves and proportional valves are rapid and accurate but also costly and consume large amounts of energy since they are predominantly oil flow choke valves. The hydraulic distributors with rapid change-over between operating positions are economical valves since they do not require a high level of accuracy in operation, are suitable for rapid and high-accuracy control via control techniques such as pulse width modulation, and they do not consume large amounts of energy because the oil passes through the maximum surface area of the apertures therein. These features enable production and operating costs to be reduced and performance to be enhanced. Increasing the mean value of the variation in the pulse width modulation (PWM) control supply with respect to the reaction speed of the main slide enables the position of the slide to be varied such that it acts as a servo valve. The reaction speed of the valve can also be increased in this specific case by reversibly supplying the slide position.

Large-aperture rapid non-return valves are used in particular in positive displacement pumps for imparting to the latter greater speed and an improved liquid-pumping rate whilst ensuring a reduced pressure differential, in particular during withdrawal, as well as in similar applications, and for preventing cavitation in the fluid-conveying lines. The method consists in covering the narrow apertures for the flow of liquid with sections of the valve disc or ring during closure, such that the width of the narrow apertures applies the dimensions of the disc or ring sections covering them (even if their thickness is greatly reduced) with a slight pressure differential, and thus produce a tight closure in the closure position. The reduced thickness of the disc or ring provides low inertia, to the benefit of the valve-reaction speed. The long edges surrounding the sections provide the liquid with a large flow area, even when the movement of the valve disc or ring is slight, far from the base thereof. The small movements provide low inertia and the large surface area decreases the loss in pressure of the flow through the large apertures in the open position.

The invention relates to an hydraulic motor comprising at least one camshaft comprising cams having at least one height per rotation of the shaft and a plurality of followers fully surrounding the cams, irrespective of their height. A closed chamber is formed in front of the followers and a control chamber is formed behind the followers. When liquid is injected under pressure into the control chamber, the followers drive the cam, and when the cams drive the followers, the liquid is expelled from the control chamber towards another part of the cycle. An assembly of valves and plugs enables the injection and expulsion of liquid under pressure to be controlled. Inverse torque can be applied to the cams in order to brake the rotation of the shaft or stop it completely, without the intervention of other mechanisms. The shaft may also rotate freely, without the cam movement being coupled to the followers. Controlling the valves and plugs, on the one hand, and integrating a follower-drive mechanism on the cam side during the withdrawal cycle, on the other, enable the device to be used as a pump with a volume of variable geometry. Furthermore, the invention concerns various embodiments with rotation in a single sense or in both senses, and the use of the device as a motor or as an hydraulic pump or as both simultaneously.
