2. WOWO/2014/186913 - METHOD FOR THE PREPARATION OF AN OLEORESIN ORIGINATING FROM A RED ALGA THAT MAINTAINS THE CAPACITY TO INDUCE THE TRANSCRIPTIONAL ACTIVITY OF THE NUCLEAR RECEPTOR PPAR-Γ27.11.2014
A61K 36/04
PCT/CL2013/000031PONTIFICIA UNIVERSIDAD CÁTOLICA DE CHILEBRONFMAN, Miguel
The present invention relates to a method for preparing an oily extract originating from a red alga, preferably Gracilaria chilenis. This process successfully maintains, in the oily extract, a high capacity to induce PPAR-gamma transcriptional activity. This process comprises the steps of: I) Extraction of the fresh alga and transport at low temperature: wherein the live, whole alga is gathered by being torn from its attachment to the seabed substrate in order then to be transferred cold (approximately 4°C); II) Preparation and chopping-up of the alga: comprising the washing of the alga with PBS (pH 7.4), extraction by centrifugation and storage under vacuum at ‑20°C. Thawing to 4°C and further washing with PBS (pH 7.4), drying by centrifugation and chopping-up of the alga with a stainless-steel pound knife into fragments of between 1-3 mm, for subsequent freezing briefly at ‑20°C for lyophilization thereof; III) Freeze-drying: lyophilization for 24 hours at ‑50°C and 0.014 mbar and storage under vacuum at ‑20°C; IV) Spraying with batchwise solid-liquid extraction of the oleoresin: the lyophilized alga is brought to ambient temperature (20-25°C) and then ground to a fine powder with an average size of less than ½ mm. A quantity of powder is placed in a flask and mixed with an appropriate quantity of solvent (dichloromethane) in order for a batchwise solid-liquid extraction to be performed. This mixture is saturated in a gaseous nitrogen atmosphere and sealed, then undergoing horizontal agitation at 34°C for 30 min. The mixture is then decanted and filtered on paper and the liquid phase is received in a flask. The solid phase is again resuspended in a liposoluble solvent, preferably dichloromethane, the earlier extraction process being repeated. The total liquid phase or extract is concentrated in a rotary evaporator, which removes the solvent, leaving the oleoresin. This product is dried under nitrogen gas to constant weight and is then resuspended in a minimum volume of cyclohexane and frozen (‑80°C) in order, lastly, to be lyophilized, thereby obtaining the solvent-free oleoresin. Furthermore, protection is sought for the oleoresin deriving from the method and the use of the oleoresin in the treatment of diabetes mellitus, insulin resistance and neurodegenerative diseases, inter alia.

E21C 41/00
PCT/CL2013/000074BASUALTO LIRA, GuillermoBASUALTO LIRA, Guillermo
A system for handling and separating minerals by size in the method for exploitation by block/panel caving. A drag conveyor (TA) operates in the transport galleries (GT), supplied by the extraction points (PE), said conveyor consisting of transverse bars which are mutually interspaced and connected by two lines of traction chains which drag the coarse mineral over a metal floor, to a grinder or a transfer shaft. The fraction of the TA which returns empty travels on the roof of the GT. On both ends of the TA, there are two pairs of wheels that are used to direct the return thereof. The front wheels are driving and move the TA by traction. On the floor of the TA, between the PE, there are grids so as to separate the fine fraction, said fine fraction being transferred via shafts until it reaches a transport sub-level, the fine material being unloaded onto a conveyor belt.

8. WOWO/2014/172799 - RECIPROCAL EXTRACTOR-FEEDER FOR THE EXTRACTION POINTS IN CAVING MINING30.10.2014
E21C 41/00
PCT/CL2014/000007BASUALTO LIRA, GuillermoBASUALTO LIRA, Guillermo
The invention relates to extractor/feeder equipment to be installed at the extraction points, in methods of underground exploitation by: block/panel caving, sub-levels and others. It consists of two platforms mounted on a chassis with wheels, the rear platform being partially mounted on the front platform. The broken mineral is placed on said platforms. The equipment is actuated in a back-and-forth movement by means of hydraulic cylinders. First, both platforms advance to the transport gallery (GT), extracting a portion of mineral; the front platform then moves back, sliding beneath the rear platform which remains static; the front platform then advances alone with another portion of mineral; and the cycle is finished with both platforms moving back, once more feeding the conveyor. When the platforms advance, the volume extracted/transported is replaced by the overlying volume, first over the rear platform, then over the front platform; as they move back, they feed the conveyor arranged in the GT so that the extracted volumes are filled.
