|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.

|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,

|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.

|PCT/CR2010/000001||UNIVERSIDAD DE COSTA RICA||UGARTE MORA, Alejandro|
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.

|PCT/CR2011/000002||LANG ORTIZ, Luis Roberto||LANG ORTIZ, Luis Roberto|
The invention relates to a fastener (plug) for anchoring a screw in a hole preformed in concrete, stone, brick, etc., said fastener comprising a plastic tubular body (2) including peripherally distributed radial ribs (3). Once the fastener has been introduced into the hole and after the screw, which has a diameter greater than the internal diameter of the tubular body (2), has been inserted inside (1) the fastener, said fastener expands radially and is compressed uniformly between the wall of the hole and the screw, thereby filling intermediate gaps and providing high holding power.

|PCT/CR2008/000005||PACHECO, Francisco||PACHECO, Francisco|
The present invention provides an apparatus for teaching various concepts related to equilibrium, symmetry of energy flow and spherical motion and comprises a mechanism having a centrally located octagear made up of eight engaging bevel gears each having a central axis that is at a 70° angle relative to it's adjacent gears. Each gear has a shaft extending centrally therefrom and outward away from the octagear, with each shaft being identical in length. Toward the end of each shaft is a crank mechanism whereby reciprocating motion delivered to the crank mechanism is translated into rotary motion of the shaft about its longitudinal axis, this rotary motion being transmitted to the gear at the end of the shaft. Connecting the crank mechanisms of each shaft are a plurality of beams with each beam spanning the space between two crank mechanisms. Each beam is capable of flexing between a first curved position and a second curved position effectively resulting in a change in the span length of the beam and thereby generating a recipricatory motion which is transmitted to the crank mechanisms.

|PCT/CR2008/000002||TALLERES INDUSTRIALES HIVA S.A.||HIDALGO VARGAS, Edgar|
The invention relates to a pallet system consisting of multiple beams positioned in parallel, but separated from one another, and two or more longitudinal bars positioned perpendicularly to the beams. A mesh mounted on the beams creates a rectangular shape defining four sides and four corners. Wheeled assemblies positioned between the beams enable the pallet to move on relatively horizontal surfaces. A braking mechanism enables a user to lock/unlock the pallet. The system also includes a hitching system which the user can use to connect the front and rear ends of adjacent pallets. The system further includes other U-shaped couplings which can be used to join the sides of adjacent pallets.
