WO/2015/074629 APPARATUS HAVING A BUOYANT SYSTEM FOR GENERATING MECHANICAL POWER||WO||28.05.2015|
||PCT/CR2014/000004||TRIPLEEE POWER SOURCE (COSTA RICA), S.A.||WILLOUGHBY, Billy Dennis|
The invention relates to an apparatus having a system for transforming buoyant force into the movement of a shaft submerged in water. The present invention is based on a mechanical, hydraulic and electrical configuration that uses air which, by means of the buoyancy thereof, drives a turbine runner. The runner is mounted inside a tank filled with water, which has a higher specific gravity than air; in this way, air is used to generate the rotation of the runner in one direction or another, depending on the configuration of the vanes. An output shaft is operationally connected to the runner, which is connected to a gearbox (step-down gear / step-up gear) or to other devices in which rotation power is needed. In said invention, the buoyant force properties of air in water are combined and used in order to produce rotation power and thus energy.
WO/2014/180452 ALIGNMENT MECHANISM FOR A LEG PROSTHESES||WO||13.11.2014|
||PCT/CR2014/000001||UNIVERSIDAD DE COSTA RICA ||ACUÑA ESPINOZA, Alejandro |
The invention relates to an alignment mechanism for sections of a leg prosthesis, each of said sections comprising one or more prosthesis-forming elements. The position of one section can be varied in relation to the other in order to obtain the general position of the prosthesis, thereby providing the user with stability and comfort and allowing the user to develop a suitable gait, as well as improving the condition in which the prosthesis is used, by means of a single adjustment. The versatile manner with which the alignment mechanism is adjusted, allowing simultaneous adjustments in the anterior/posterior and medial/lateral directions and internal/external rotation, is advantageous over other leg prosthesis alignment systems available on the market which generally use four or more adjustments.

||PCT/CR2013/000001||BERTOZZI NAVARRO, Luis Alberto||BERTOZZI NAVARRO, Luis Alberto|
The invention concerns an internal combustion modifier for diesel and petrol engines which, on the basis of a series of components, enables hydrogen to be reliably supplied to the engine, as a substitute for the diesel or petrol, by means of an integrated system which starts at the source of electrical energy and continues to the final point at which the hydrogen is injected into the engine.
WO/2014/071893 COMPOUND REINFORCED WITH QUARTZ OR GLASS FIBRE AND FLUID PHOTO-CURING RESIN, METHOD FOR RECONSTRUCTING TEETH AND METHOD FOR USING SAID COMPOUND||WO||15.05.2014|
||PCT/CR2012/000004||RODRÍGUEZ POSADA, Mario Alberto||RODRÍGUEZ POSADA, Mario Alberto|
The invention relates to: a compound for medical and dental use, made from quartz or glass fibre and liquid photo-curing resin; the design of dental structures inside and outside the mouth using said compound; and the dosage form of the compound as a treatment method.
WO/2014/040575 CONFIGURABLE, DETACHABLE AND RECYCLABLE PALLET||WO||20.03.2014|
||PCT/CR2012/000003||CAJAS PARA EXPORTACIÓN RETORNABLES S.A.||HIDALGO VARGAS, Edgar|
The invention relates to a configurable pallet that can be easily assembled in order to meet the particular load requirements for a given use. The pallet includes elongate structural platform members (10, 10') used in different configurations with supporting elements (30) or structural reinforcing beams (20). The platform members (10') include conical projections (14', 16') that are engagingly inserted into frustoconical openings (14 and 16 or 14a and 16a) in order to maintain the structural members in their corresponding position, perpendicular to one another, as well as using securing members. When the reinforcing beams (20) are used, the structural integrity of the loading pallet is improved in order to reduce wear owing to tensioning/relaxing, preventing or minimising the possibility of loosening. A diaphragm plate (225) is optionally used in order to improve the structural stability of the beam (20).
WO/2012/152233 VACUUM DEEP-FAT FRIER||WO||15.11.2012|
||PCT/CR2012/000002||UNIVERSIDAD DE COSTA RICA||QUESADA CORRALES, Guido Mauricio|
The invention relates to a continuous vacuum deep-fat frier in the form of a duct, characterised in that said duct extends horizontally along a path above the inlet and outlet points, such that the pressure in the higher part of the duct is below the atmospheric pressure as a result of difference in oil level. In order to prevent the oil from overflowing, both ends of the duct are in the form of an inverted siphon and the upper part of the duct comprises a vacuum pump for extracting the vapours produced during the frying. An auxiliary line connects the inlet and outlet siphons by means of the lower part thereof in order to maintain the level of the oil. The oil heats up by means of heat sources through the walls of the duct. In order to protect the product to be fried, the product can be optionally placed inside closed baskets. An endless screw system, a conveyor belt or a pump system transporting the product by drive can be installed for moving the product through the frier,
WO/2012/152232 METHOD FOR OBTAINING AN EXTRACT RICH IN ELLAGIC ACID TANNINS FROM FRUITS THAT CONTAIN THESE COMPOUNDS, AND RESULTING EXTRACT||WO||15.11.2012|
||PCT/CR2012/000001||UNIVERSIDAD DE COSTA RICA||ACOSTA MONTOYA, Oscar Gerardo|
The invention relates to the field of biotechnology and to processes that employ membrane technologies. In particular, the invention relates to a method for obtaining an extract rich in tannins of ellagic acid from blackberries (Rubus spp.) and from other fruits that contain these compounds, as well as to the extract obtained using said method. The method is essentially based on baromembrane technologies that allow mechanical separation and effective fractionation between the polyphenol compounds, by means of interactions between the physico-chemical properties thereof, the material of the membrane and the molar mass of same, thereby allowing enrichment of a fraction of the natural extract with ellagic acid tannins and modification of the content thereof in terms of anthocyanins and other compounds such as sugars and acids.
WO/2012/136172 METHOD FOR PRODUCING INJECTABLE FORMULATIONS OF BLOOD-DERIVED PROTEIN MATERIALS, AND MATERIALS OBTAINED USING SAID METHOD||WO||11.10.2012|
||PCT/CR2011/000001||UNIVERSIDAD DE COSTA RICA||SEGURA RUIZ, Alvaro|
The invention relates to a method for producing injectable pharmaceutical formulations of blood-derived protein materials, including the steps of fractioning the source material in a polymer/salt aqueous two-phase system in the presence of phenol, purifying the top phase of the system by means of precipitation with caprylic acid and purifying the bottom phase by means of thermocoagulation, increasing the purity of the materials in both phases through chromatography, removing viral particles by means of the nanofiltration of both preparations, and formulating, stabilizing, and packaging the resulting materials.

A structural connection device for structural elements in the form of a solid or closed section bar and of substantially circular form, typically bamboo, is characterized in that it is composed of two plates provided with various orifices or grooves for affixing additional structural elements placed in a diametrically opposing position on the outer surface of said bar, said plates being joined together by means of one or more threaded bars or bolts with the respective washers and nuts thereof, which diametrically traverse said bar through one or more holes previously made in said bar, pressing said plates against the surface of said bar. Said bolts in turn incorporate springs or a flexible connector for absorbing the dimensional variation in bamboo.
