WO/2017/039427 SYNTHESIS OF A NOVEL MATERIAL: TITANIUM (+III) PHOSPHITE ΤI2(ΗΡO3)3, ANODE FOR LITHIUM-ION BATTERIES||WO||09.03.2017|
||PCT/MA2016/000014||UNIVERSITE MOHAMMED V DE RABAT||UNIVERSITE MOHAMMED V DE RABAT|
The present invention relates to the synthesis of a novel material, titanium (III) phosphite [Τi2(ΗΡO3)3], which did not previously exist in the literature. Said compound crystallizes in a hexagonal system, space group P63/m. Said synthesis was carried out in the context of a power storage application. Up to now, in batteries, phosphites have only been used in organic forms as additives in electrolytes playing the role of stabilizers, thus enabling improved safety of use. In the literature, inorganic metal phosphites have never been used as anode material in rechargeable lithium-ion batteries. This is the subject of this work.

WO/2017/007296 VACUUM TUBE SENSOR OPERATING UNDER ATMOSPHERIC PRESSURE||WO||12.01.2017|
||PCT/MA2015/000031||UNIVERSITE INTERNATIONALE DE RABAT||BENABDELLAH, Abdellatif|
The invention relates to a solar water heater with vacuum tubes operating under atmospheric pressure. It uses a heat exchanger in the form of a corrugated tube placed at the top of the tank. The tank is filled with still water which stores the heat from the solar radiation captured by the vacuum tubes. The water for use is heated by heat exchange from the still water through the corrugated tube. The water heater also supplies a central heating circuit.
WO/2017/007295 SYSTEM FOR PRODUCING FRESH WATER BY MULTIPLE-EFFECT HUMIDIFICATION-DEHUMIDIFICATION||WO||12.01.2017|
||PCT/MA2015/000027||UNIVERSITE INTERNATIONALE DE RABAT||BOUYA, Moshine|
An invention is disclosed here that relates to a device and a process for producing fresh water by multiple-effect humidification-dehumidification. This system uses seawater, brackish water, river or well water in order to cool the humidified ambient air inside a condensation chamber (5) that produces fresh water from the humidity that it contains. The ambient air is saturated with water by means of the evaporation of water by solar heating (3). A second effect (10) uses the high output temperature of the fresh water to restart the process in the following units.
WO/2016/204595 DEVICE FOR PRODUCING SECTION HONEY||WO||22.12.2016|
||PCT/MA2016/000011||BEN TOUNSI, Mostafa||BEN TOUNSI, Mostafa|
The present device relates to bee-keeping, and concerns the production of honey contained in the wax structure (the section, or comb) of same, and consists of a frame made from transparent food-grade plastic material, the frame being formed as a cylindrical body positioned within a body having a square cross-section with rounded corners. For the purpose of producing section honey, a thin sheet of comb foundation is arranged between two similar frames positioned back-to-back, to constitute the bottom of the honey section, over several frames, then the assembly is closed by means of partitions behind the sides of the two frames, and a set of such frames is arranged inside a honey body, which is deposited in turn on the hive, in order for the bees to start to seal the wax divider sheets, then fill them with honey and, after the completion of the sections, the two frames are closed by means of two transparent plastic covers, which give the assembly an attractive appearance when on display and for sale.
WO/2016/195466 REDUCING PHASE SHIFT IN RADIO-FREQUENCY TRANSMISSION LINES FOR INTEGRATED CIRCUITS||WO||08.12.2016|
||PCT/MA2015/000032||UNIVERSITE INTERNATIONALE DE RABAT||AOUTOUL, Mohssin|
The invention proposes an interconnection technique for a 'flip-chip quad flat no-lead' (FC QFN) housing. This technique helps reduce the phase shift in the line transmitting a radio-frequency signal. The radio-frequency inputs/outputs of the die (7) are connected to the lead fingers of the casing (9) by a small microstrip (8), 1000 μm long. Said microstrip is charged with a series capacitance that consists of a stack of fingers rather than inter-digitated fingers, referred to as a capacitance-charged microstrip. The capacitance uses a ceramic dielectric material. This technique helps reduce the effect of induction in the transmission line and thus to reduce the associated phase shift caused by the other electrical interconnections (wire connections).

The invention relates to a process for preparing synthetic calcium fluoride (CaF2) (min 90 wt% CaF2) from fluosilicic acid. Said process includes the following steps: (a) reacting fluosilicic acid (H2SiFe) with ammonium hydroxide or ammonia in a first reactor (1) so as to obtain a first thick suspension, filtering said first suspension so as to obtain a filtrate containing an ammonium fluoride solution, (b) precipitating the ammonium fluoride solution, obtained in the form of a filtrate in step (a), with calcium carbonate in dry form or in the form of a suspension having a concentration of between 10 and 80 wt%, in a second reactor (3) so as to produce a second suspension containing the calcium fluoride and the ammonium carbonate, filtering said second suspension so as to obtain a filter cake containing calcium fluoride, and a filtrate containing an ammonia carbonate solution, washing and drying said filter cake so as to obtain calcium fluoride and a washing filter cake containing an ammonium hydroxide solution, wherein a portion of the second suspension, of from 10 to 70 wt%, is recycled to the second reactor (3) so as to enhance the crystallization of the calcium fluoride, change in most of the ammonia from the second reactor in step (b) due to partial decomposition of the ammonium carbonate under reactor conditions, then washing and sending said ammonia back into the first reactor, and collecting and treating, by means of distillation and condensation, the ammonium carbonate solutions obtained as filtrate and washing filter cake in step (b), so as to recover the liquid ammonia which is recycled to the first reactor (1).
