WO/2015/178752 HYDROMETALLURGICAL PROCESS FOR THE RECOVERY OF COPPER, LEAD AND/OR ZINC||WO||26.11.2015|
||PCT/MX2014/000090||MINERA PECOBRE, S.A. DE C.V. ||BENAVIDES PÉREZ, Ricardo |
The invention relates to a hydrometallurgical process for the treatment of polymetallic minerals and sulphur concentrates of copper and zinc, and by-products from lead smelting plants and zinc plants, treated independently and/or as mixtures with relevant contents of lead, copper, zinc, iron, gold and silver, such as the matte-speiss mixture from lead smelting plants, and copper cements from the purification processes of electrolytic zinc plants. The process allows the recovery of the metals copper and zinc, copper in the form of the basic salts thereof, and zinc, that can be hydroxides, carbonates, hydroxysulphates or mixtures thereof; the production of stable arseniferous wastes; and the effective and efficient recovery of Pb, Au and Ag as a concentrate of lead sulphide and/or lead sulphate Au and Ag.
WO/2015/178753 BRANCHED GEMINAL ZWITTERIONIC LIQUIDS, METHOD FOR OBTAINING SAME AND USE THEREOF AS WETTABILITY MODIFIERS HAVING VISCOSITY REDUCING PROPERTIES||WO||26.11.2015|
||PCT/MX2015/000077||INSTITUTO MEXICANO DEL PETRÓLEO ||RAMÍREZ PÉREZ, Jorge Francisco |
The invention relates to a method for producing branched geminal zwitterionic liquids based on bis-N,N-dialkyl-N-polyether-betaine or bis-N,N-dialkenyl-N-polyether-betaine or bis-N,N-dicycloalkyl-N-polyether-betaine or bis-N,N-diaryl-N-polyether-betaine, and to the use of same as agents for modifying the wettability of rock, such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, in the presence of brines having a high concentration of divalent ions, such as calcium, magnesium, barium and strontium, and under high temperature and high pressure conditions, in enhanced oil recovery processes in order to increase oil production. In addition, the branched geminal zwitterionic liquids of the invention can act as viscosity reducing agents for heavy oils with a high concentration of polar fractions, both in extraction and production operations and transport and storage operations, thereby allowing production levels of this type of oil to be increased. An additional advantage of these zwitterionic liquids derives from their molecular structure and the fact that they can be manipulated so as to be soluble in water, hydrocarbon or other polar or non-polar solvents.

WO/2015/174815 LATCH FOR COMPACTOR TRUCK HOPPER||WO||19.11.2015|
||PCT/MX2015/000075||CASTRO SALINAS, Moisés ||CASTRO VARGAS, Fabián Moisés |
The present invention relates to an opening and closing latch for a compactor truck hopper that can be used with refuse compactor trucks. The latch for a compactor truck hopper comprises: two identical upper supports attached to the upper left and upper right parts of the container of the truck; two hook-shaped lower plates located in the lower left and lower right parts of the container of the truck, each plate being accompanied by a stud, a spring, and securing elements. The hopper latch of the present invention facilitates refuse unloading, since when the hopper comes into contact with the lower part of the latch, the lower part of the latch automatically closes, and when the hopper ceases to be in contact with the lower part of the latch, the lower part of the latch automatically remains free to be opened. Furthermore, the hopper latch, according to the present invention, provides complete and correct closure of the hopper to prevent undesired spillage of leachates during refuse compaction.
WO/2015/174816 PROTECTIVE CASING FOR AN ELECTRICAL ENERGY READER, INCLUDING A GLASS LENS||WO||19.11.2015|
||PCT/MX2015/000082||GARZA LEAL, Jesus ||GARZA LEAL, Jesus |
The invention relates to a protective casing for electrical energy readers made from polycarbonate. According to the invention, glass inserts are positioned on the casing in the consumption data reading areas and the data area of the meter. The glass inserts comprise a bevelled periphery allowing same to be affixed with adhesive and said inserts are also integrated by means of plastic injection, to allow clear and simple reading. The casing also comprises a peripheral ring at the front that provides impact resistance. The resulting plastic casing with glass reading areas is advantageous in that, although the plastic becomes opaque as a result of the sun's rays, the reading areas always remain visible.
WO/2015/174817 IMPROVED SYNERGISTIC COMPOSITION BASED ON A NATURAL EXTRACT OF ALLIUM SATIVUM AND SYNTHETIC INSECTICIDE COMPOUNDS FOR THE CONTROL AND/OR ELIMINATION OF PEST INSECTS, PRODUCTION METHOD THEREOF AND USE OF SAME||WO||19.11.2015|
||PCT/MX2015/000102||MEZCLAS Y FERTILIZANTES S.A. DE C.V. ||MIRANDA VALENCIA, José Luis |
The invention relates to an improved synergistic composition for the control and/or elimination of pest insects, characterised in that it comprises: a) 20% to 80% natural extract of Allium sativum; b) 54% to 9% at least one synthetic insecticide compound selected from group I, II and III and/or mixtures of same; c) 18% to 10% surfactant; and d) 8% to 1% diluent, all adding up to 100%. In these percentages the aforementioned components have improved effectiveness and prolonged effect in terms of pest insect control, guaranteeing control of adults, nymphs, larvae and eggs, particularly in adults by altering behaviour and reproduction, since the extract of garlic (Allium sativum) improves the effectiveness of the synthetic chemical compounds using its basic effects that influence the behavior or physiology of the insect, in particular the hyperexcitation effect on the nervous system. The aqueous extract of garlic (Allium sativum) is obtained by means of maceration and is mixed with the other components in the tank or directly in the field in concentrations in accordance with the formulation in order to guarantee the elimination of pest insects that affect crops.
WO/2015/174814 SAFETY VALVE FOR THE HYDRAULIC HOPPER LIFTING SYSTEM OF COMPACTOR TRUCKS||WO||19.11.2015|
||PCT/MX2015/000074||CASTRO SALINAS, Moisés ||CASTRO VARGAS, Fabián Moisés |
The invention relates to a safety valve for preventing the piston of hydraulic cylinders from falling, by retraction, as a result of pressure drops in the hopper lifting system of a compactor truck. The safety valve comprises: a valve body equipped with first and second inlets and disposed on a first hydraulic fluid inlet located in the lower part of a hydraulic cylinder; a retaining cartridge; first and second hoses for hydraulic fluid, connected to the first and second inlets of the valve body; a rigid tube connected to a second hydraulic fluid inlet located in the upper part of the hydraulic cylinder; and a T-shaped connection located between the second valve body inlet and the second hose, such that a pressure increase in the first inlet of the valve body lifts the retaining cartridge, thereby unblocking the hydraulic fluid passage and lifting the hopper, while a pressure decrease in the first inlet of the valve body causes the retaining cartridge to fall, thereby closing the hydraulic fluid outlet from the hydraulic cylinder and locking the hopper in the open position, an increase in pressure being required in the second inlet of the valve body in order for the cartridge to be lifted and the hydraulic fluid released, allowing the hopper to be lowered.
WO/2015/174812 IMPROVED METHOD FOR PREPARING ZILPATEROL||WO||19.11.2015|
