1. WO/2016/184477 HYPER LIGHTWEIGHT FIBRE-REINFORCED CONCRETE STRUCTURES SYSTEMWO24.11.2016
E02B 3/10
PCT/DZ2016/050005CHOUAKI, BoussadCHOUAKI, Boussad
This invention, entitled "hyper lightweight fibre-reinforced concrete structures systems" or SySHABfib, relates to special very lightweight prefabricated latticed and modular civil engineering structures reinforced with metal or synthetic fibres. Its idea was born out of the realization of the singular function of certain parts that make up mound breakwaters, which has them acting exclusively as supports for other parts of these constructions. This function, because of geometrical constraints, therefore imposes an excessive superfluous mass on these parts. The idea is therefore to replace this massive structure with an excessively lightweight - and economical - structure, without affecting the overall geometry of the constructions, and in strict adherence to the principles, standards and regulations of science and technology from which this invention is inspired, namely in the main, civil engineering, geotechnics and geosynthetics.

2. WO/2016/165722 PYROTECHNIC EMERGENCY DEVICE FOR LANDING GEARWO20.10.2016
B64C 25/30
PCT/DZ2015/000003DJELLABI, MohamedDJELLABI, Mohamed
The invention combines the use of two types of energy. It relates to an auxiliary pyrotechnic device operating in complete autonomy without using any source of energy or the control appliances of the aircraft. The device provides ultimate emergency manoeuvring in the event of complete blockage of the deployment of the landing gear. Said device is autonomous and generates a high level of hydraulic power from a reserve of hydraulic oil compatible with that of the aircraft stored at zero pressure in actuating cylinders actuated by a pyrotechnic charge stored in a gas generator. The technique of said device consists in using the force of the solid gases (propellant) to create a high hydraulic pressure that can move the cylinders and the hooks of the landing gear. The design of said device is characterised by the duplication of the components so as to reduce risk of failure.

3. WO/2016/124207 ENERGY ABSORBER PROVIDED WITH A TUBE HAVING S-SHAPED CURVES FOR USE IN SOLAR COLLECTORSWO11.08.2016

PCT/DZ2016/050003DEMAGH, YassineDEMAGH, Yassine
The invention relates to an energy absorber (1) for absorbing solar radiation and transferring said solar radiation energy to a heat-transfer fluid (4) which flows inside at least one central tube (2) located in the energy absorber. The central tube has at least one S-shaped curve (figure 2A and figure 2B), otherwise it has at least one combined "S/straight" shape (figure 2C). The central tube (2) includes a surface coated with at least one absorbent selective coating layer in order to absorb the most solar radiation possible. The central tube (2) is surrounded (3) by at least one shell tube (31). The shell tube includes at least one surface which is transparent to solar radiation. The shell tube includes at least one inner surface. The central tube and the shell tube may optionally be positioned coaxially, creating an inner space bounded by the surface of the central tube and the inner surface of the shell tube (3). At least one unit for collecting solar radiation comprises at least one reflective inner surface for directing the solar radiation towards the central tube arranged inside the energy absorber. The solar collector includes a parabolic mirror (6) having a reflective surface (6E) for directing the radiation toward the focal line (7) of the reflective surface (6E), the reflective surfaces optionally being Fresnel mirrors. The energy absorber may optionally be positioned on the focal line of the reflective surface.

4. WO/2016/110298 METHOD FOR ESTIMATING THE VOLUME OF CLAY (V CLAY) ON THE BASIS OF THE FORMATION DENSITY, OF THE POROSITY AND OF THE ACOUSTIC VELOCITIES IN CLAY-SANDSTONE RESERVOIRSWO14.07.2016
G01V 1/30
PCT/DZ2015/050006ENTREPRISE NATIONALE DE GEOPHYSIQUECHEGROUCHE, Farid
Method of estimating the volume of clay (Vclay) characterizing a clay-sandstone reservoir, on the basis of the diagraphic recordings at the level of the well, the global density (ρb) and the velocities of the longitudinal (Vp) and transverse (Vs) waves and the porosity (ϕ). On the scale of the reservoir, one proceeds firstly with the estimation of the volumes of the acoustic velocities of the longitudinal (Vp) and transverse (Vs) waves and of the global density of the formation (ρb) on the basis of the seismic data processed in terms of amplitudes preserved by using a stratigraphic inversion. Thereafter one proceeds to the estimation of the volume of the total porosity (ϕt) on the basis of the acoustic velocities of the longitudinal (Vp) and transverse (Vs) waves and of the global density of the formation (ρb), which are generated by the inversion, using a multilinear relation. The volume of clay (Vclay) is estimated by this method by using the volumes of the seismic velocities (Vp) and (Vs), of the global density (ρb) and of the porosity (ϕ).

Our system consists of two devices, one of which is positioned on any kind of vehicle (light vehicle, utility vehicle, lorry, bus), the other being held by control agents (figures 1 & 5), provided with transparent communication. When stationed at a random traffic checkpoint, the police officer or other can easily read and see, at first glance, on the visual display of the "AUTOVIGIL" system, positioned on the back of the inside rear-view mirror - (figures 1 & 2) - the type of speed violation, without stopping or slowing those who have committed no fault. Moreover, he can at any time view a batch of data stored in the memory and referring to violation speeds over a time period, for example: the time and date of the violation, the type of violation, the place, (in a town, on a main road or motorway, violation speed, etc.) via the receiver device having a touch screen provided for this operation. This has a significant impact on accident prevention and, apart from the control time saved, reckless drivers are caught in the act. In conclusion, we consider that the final free mounting (figure 9) that rests on the GPS module remains the best model and the most suitable solution for this scourge. The driver is not required to make any movement; the only obligation imposed on him is a vital one: his speed.

PCT/DZ2015/000001NOUI, WalidNOUI, Walid
The invention is characterized by a chassis in the form of a sole for the foot, on which there are mounted three spherical rollers, connected thereto at the projections of the support points for the posterior static support triangle; two front rollers, disposed transversely to the major axis of the foot, the rolling axes of said rollers being parallel and their projections on the chassis being perpendicular to the major axis of the foot and only executing linear movements in the direction of the major axis of the foot; a rearwardly pivoting spherical roller. The three support points for the posterior static support triangle of the foot correspond successively to the head of the first metatarsal, to the head of the fifth metatarsal and to the supporting centre of the calcaneus. A propulsion device is placed at the front of the chassis in order to protect it from friction with the ground.

8. WO/2015/104027 METHOD FOR PRODUCING METALLIC MULTIPOLAR LIQUID SOAPWO16.07.2015
C07C 51/41
PCT/DZ2014/000007ZEMOURA, AdelZEMOURA, Adel
The invention concerns the method for producing metallic multipolar liquid soap, a novel liquid detergent with a modest production cost owing to the simplicity of the materials intended for the production of same, given that preservation materials and other additional materials, which are essential in other liquid detergents, do not need to be used; said soap has powerful cleaning strength requiring little effort; moreover, the soap is compatible with all cleaning operations. The soap has a desirable and appealing glossy appearance. This can be seen in specific colours added to the colours and forms of metal, such as a transparent glossy golden colour, a transparent glossy copper colour and a transparent glossy silver colour, all of which are original and hitherto not conceived by any other manufacturer.

The public-works loader grader is provided with a diesel engine for carrying out all the above-mentioned operations. The size of the loader grader enables it to move even over small surfaces on the work site. The turret (19) is fitted with a worm drive that also allows same to pivot to the left and right.

10. WO/2015/096842 CIRCULAR WING FOR VERTICAL FLIGHTWO02.07.2015
B64C 11/18
PCT/DZ2014/000005GUERFI, MohamedGUERFI, Mohamed
According to the invention, the assembly of the half-sphere airplane wing made it possible to create another form of flight (vertical flight), controlling air flow only on the top surface of the circular wing, said assembly being a perfect re-adhesion and tangential to the smooth surface of the top circular wing surface. While the air speed on the bottom surface of the circular wing is equal to zero, the air flow will make it possible to create vertical thrust below the circular wing which will increase in proportion with air speed. Said technique, which has a wide range of industrial uses and will put an end to critical problems, can be cited as follows: 1) on motor vehicles and for monitoring roads; 2) in military service; air transport; and 3) in space; transporting satellites.
