1. WOWO/2014/101922 - HYDRAULIC SYSTEMS FOR ACCUMULATING/RELEASING RENEWABLE ENERGY03.07.2014
E02B 9/00
PCT/DZ2013/000007CHOUAKI, BoussadCHOUAKI, 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.

2. WOWO/2014/086378 - INTERFACE HAVING EARTH FAULT CURRENT12.06.2014
H02H 9/02
PCT/DZ2013/000006MEKIMAH, DjamelMEKIMAH, 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.

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.

5. WOWO/2013/149623 - METHOD FOR QUANTITATIVELY EVALUATING THE FLUID TORTUOSITY AND THE CHARACTERISTICS OF THE SOLID AND OF THE FLUIDS IN A HETEROGENEOUS RESERVOIR10.10.2013
G01V 1/50
PCT/DZ2013/000003ENTREPRISE NATIONALE DE GEOPHYSIQUE ENAGEOOUABED, 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.

8. WOWO/2012/152289 - WAVE-DRIVEN ELECTRICAL GENERATOR15.11.2012
F03B 13/12
PCT/DZ2012/000002ARBANE, NasserARBANE, 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.

10. WOWO/2011/144215 - METHOD FOR ATTENUATING HARMONIC NOISE IN VIBROSEIS BY MEANS OF REFERENCED TIME-VARIANT FILTERING24.11.2011
G01V 1/37
PCT/DZ2011/000003ENTREPRISE NATIONALE DE GEOPHYSIQUE - ENAGEO- FILIALE DU GROUPE SONATRACHCHEGROUCHE, Farid
The invention relates to a method for improving the quality of vibroseismic data, particularly vibroseismic data acquired in slip-sweep mode, by estimation and attenuation of the different harmonic components (see fig. 3). Said components are estimated from the Ground-Force signal using a separation technique with two options, namely least squares or time-frequency, both of which are adapted to the component to be extracted, and the noise is subdivided into classes. The harmonics specific to the recording in question are calculated and subtracted. Finally, the reference noises relative to each class are calculated and re-estimated using a multiple input/output method with dynamic management of the frequency band, which can be achieved using one of three options: global, cascade or multi-reference, followed by subtraction from the contaminated recording. The data quality is improved by means of appropriate source signal shaping.
