||PCT/DZ2014/000001||BAROUD, Billal||BAROUD, Billal|
The invention relates to a hydraulic pump having axial pistons (10, 11) and a grooved sliding shaft (6) that is contained in a dispensing throat (22). Said grooved shaft (6) is a mediator between the pump and gearbox for the power takeoff and between the pump and the ram for the valve. The grooved shaft (6) is controlled by the air compressed in the chamber, which jostles the shaft. The grooved shaft (6) being inserted into the drive shaft (1) and engaging with the inner grooves (9) of same starts the operation of the pump, and, at the same time, the grooved shaft (6) closes the slit of the radial channel (20) for oil return. When the air is cut, said air is automatically decompressed in the chamber, and, with the return of the spring, the grooved shaft (6) exits the drive shaft (1), which causes the operation of the pump to stop and the throat of the grooved shaft enables the return of the oil which passes through a radial channel (20) in the cylinder bloc and the oil returns toward the tank.

||PCT/DZ2013/000007||CHOUAKI, Boussad||CHOUAKI, Boussad|
The present invention ''Hydraulic systems for accumulating/releasing renewable energy'', concerns the storage of energy produced by harvesters that are not continuously active. These systems have been designed for countries in dry areas of the planet. The energy is stored by pumping water up from a low reservoir to a high reservoir during off-peak hours. The energy is released during peak hours, by passing the water through turbines of a hydroelectric system to be attached to hydraulic facilities not initially designed for this purpose. These systems are adapted to the natural local conditions in a novel manner, i.e.: 1. Transfers are extended to all kinds of drinkable fresh water reserves, including other volumes of non-drinkable (salt or brackish) but biologically healthy water, without it being possible for the different kinds of water to mix with each other. 2. Optimisation by simplification, standardisation, and updating of technologies. 3. A novel field in Hydrology.

||PCT/DZ2013/000006||MEKIMAH, Djamel||MEKIMAH, Djamel|
The invention concerns an interface for cutting off the power supply for any fault current Id ≤ 300 milliamperes such that: Id≥ IPE + k.Ih where IPE represents the current returning to the power source via the protective conductor connecting the exposed conductive parts to earth and Ih ( ≤ 10 or 30 milliamperes) represents the current returning to the power source by means other than via the protective conductor or via an active conductor. Current Ih is therefore likely to travel through a person. In this way, the interface protects people and property against ground insulation faults and against certain direct contacts independently of the earth of the exposed conductive parts and of external conditions. It also protects people in the event of a failure in the protection of an area using the same earth in case of a fault.

||PCT/DZ2013/000001||NEMDIL, Ali||NEMDIL, Ali|
The present invention relates to a concrete pump having a hydraulic or mechanical reduction gear. The concrete pump is to be generally used in the field of civil engineering, in particular for preparing and mixing concrete. Said concrete pump may include a hydraulic or mechanical reduction gear. A first reduction gear is secured to and driven by a dual-body hydraulic pump. Said hydraulic reduction gear transmits a rotary movement in order to drive a mixing shaft provided with blades. The primary aim of the present invention is to provide a concrete pump for preparing and mixing concrete and transferring the concrete to the very place at which it is to be poured. The transfer can be vertical or horizontal. Said machine can be towed and thus easily brought to a worksite.
||WO||WO/2013/149623 - METHOD FOR QUANTITATIVELY EVALUATING THE FLUID TORTUOSITY AND THE CHARACTERISTICS OF THE SOLID AND OF THE FLUIDS IN A HETEROGENEOUS RESERVOIR||10.10.2013||
||PCT/DZ2013/000003||ENTREPRISE NATIONALE DE GEOPHYSIQUE ENAGEO||OUABED, Noureddine|
Method of quantitative evaluation of the fluid tortuosity in a heterogeneous reservoir on the basis of diagraphic measurements (gamma ray, global density and the slownesses of the longitudinal and transverse waves) which allows the estimation of the permeability and the size of the pores. It affords an improvement in estimating the formation resistivity factor. The evaluation is undertaken of the porosity (phi) on the basis of the slowness of the longitudinal waves, of the volume of clay (Vsh) on the basis of the gamma ray and of the effective porosity on the basis of phi and Vsh calculated previously. The fluid tortuosity (tau) is determined using several petrophysical parameters. At the end, the structure incompressibility modulus (Ks), the formation resistivity factor (F), the formation water saturation (Sw), the dimensionless frequency (X), the permeability (KO) and the size of the pores (d) are determined.

||PCT/DZ2012/000004||LAKHDARI, Mustapha||LAKHDARI, Mustapha|
The invention relates to a telemetry system for collecting tap (5)-water consumption measurements in real time through a self-powered electromechanical device that can be integrated inside the tap or provided as an outer module capable of being adapted to the outlet of any type of tap (5). The electromechanical device automatically or manually adjusts the water flow rate, and indicates the volume of water to be used, displays the consumption measurements on a display (6) in real time, and sends the measurements to a storage device (2, 3) in order to store same in an external module and analyze same with a view to defining excessive consumers, losses, leaks, etc., and sharing the information, via the Internet (1), with other users in the region and vice versa. The system can be used for improving host analysis and water management and distribution capabilities.

||PCT/DZ2012/000002||ARBANE, Nasser||ARBANE, Nasser|
The invention relates to a wave-driven generator that is an electricity generator operating by means of energy contained in the movement of waves in the sea. The operating principle of said wave energy converter is a giant pulley (10) with monodirectional rotation (one-way). In order to capture the movement of the waves, a rack (2) (bar toothed on both sides) is fixed to a buoy (1) (to a float) that moves up and down. This drives a gear for converting said back-and-forth motion into a rotating movement. This causes the movement of the giant pulley (10). If it is applied in the field of mechanics, the invention will enable the improvement, for example, of the operation of a ratchet wrench by eliminating the empty return.
