C08L 95/00
PCT/CO2013/000005CORPORACION PARA LA INVESTIGACION Y DESARROLLO DE ASFALTOS EN EL SECTOR TRANSPORTE E INDUSTRIAL-CORASFALTOSQUINTERO RANGEL, Luz Stella
The invention relates to a method for modifying an asphalt binder using, as an additive, a nanocomposite of: functionalised multi-walled carbon nanotubes dispersed in a styrene-butadiene-styrene polymer matrix (SBS/MMWCNT). The asphalt modified with the SBS/MMWCNT nanocomposite has substantially improved mechanical resistance to deformations and to loads at high temperatures, such that the life of the flexible paving is improved. The asphalt mixtures produced with this novel modified asphalt binder have considerably less rutting, are classified as high-modulus asphalt mixtures when produced from asphalt of medium (60/70) or greater hardness, and are not sensitive to moisture effects.

H05F 7/00
PCT/CO2012/000003ARNEDO GONZÁLEZ, Luis RaúlARNEDO GONZÁLEZ, Luis Raúl
The invention relates to an electrical apparatus which perpetually generates electrical energy when it stores transient electrical currents, said apparatus being constructed with at least second-order differential equations LC, floating with respect to earth, which equations use electrical superconductors to eliminate the damping factor. The apparatus, which oscillates perpetually, is formed by a lightning arrester (1) connected, by means of a bare 4/0 AWG down cable (2) containing an electrical fuse (6), to the terminal of a capacitor (5) which is connected in parallel with a transformer (4) having a primary winding that is implemented with a superconductor, all on an acrylic base (8) and all supported on a PVC tube (3), as well as a secondary winding of transformer (7), together forming a perpetual oscillator. In addition, a floating short-circuit coil (9) is placed upstream of the fuse so that it stores the excess electrical energy when the electrical fuse is opened.

4. WOWO/2014/000717 - BIOMETRIC VALIDATION METHOD AND BIOMETRIC TERMINAL03.01.2014
G06Q 20/40
PCT/CO2013/000003IDENTICA S.A.BOTERO MONTAÑO, Rodrigo
The invention relates to a biometric validation method that is initiated when a person to be identified makes a biometric authentication request by introducing his/her PIN into an electronic device. The request is made through an authorisation centre which receives both the PIN introduced and the code that identifies the fingerprint capture and encoding device to be activated. Upon receiving this information the activation request is sent from the centre to the fingerprint capture and encoding device. Once the print has been captured, a print template is obtained, which is then encrypted and sent to the centre where it is compared with reference templates. Subsequently, the centre sends a corresponding positive or negative authentication signal to the person that made the request. The method can be used for biometric validation using a biometric terminal equipped with means for communicating directly with the centre without any additional software or hardware being installed in the electronic device that requires the biometric identification.

5. WOWO/2013/189466 - DEVICE FOR INFLATING THE LARYNGEAL MASK AND THE ENDOTRACHEAL TUBE BALLOON27.12.2013
A61M 16/04
PCT/CO2013/000002TAFUR BETANCOURTH, Luis AlbertoTAFUR BETANCOURTH, Luis Alberto
The present invention pertains to the field of medicine and relates to a novel alternative for significantly improving control of the inflation pressure of the laryngeal mask and endotracheal tube balloon in the wake of a procedure for accessing airway control. Thus, the present invention provides a novel device that allows, in an economic, appropriate and efficient manner, measurement of the sealing pressure of airway‑management medical devices, from insertion and positioning thereof up to removal thereof, not only during the use of the devices for short periods but also in cases of extended intubation. To achieve this, the present invention provides a disposable, affordable, economic and easy‑to‑use element that allows measurement of the pressure achieved after inflation of the endotracheal tube balloon (hereinafter called "ETB"), of the laryngeal mask and of any device that, in order to be sealed, requires the use of a reservoir of air. Adequate, appropriate control of this pressure results in improved health care and a reduction in side effects deriving from non‑monitored use of sealing pressures and volumes.

6. WOWO/2013/167094 - ROBOTIC PLATFORM FOR IN-PIPE INSPECTION14.11.2013
F16L 55/38
PCT/CO2013/000001UNIVERSIDAD INDUSTRIAL DE SANTANDERARCHILA DÍAZ, John Faber
The invention relates to an inspection robot for pipes used to transport different types of fluids (liquids or gases). The robot considers the interaction between the fluid, the pipe and the robot in order to prevent: overpressure in the pipe above the maximum operating pressures, and pressure drops below vapour pressure, thereby preventing cavitation in the case of liquids. The robot extracts energy from the fluid and uses said energy to move itself, the speed of the robot also being controlled such that it can move at a constant speed, eliminating variations in speed typical of fluid transport. The reconfigurable constant speed is achieved using a control system which maintains the speed at a reference value and evaluates the interaction between the robot, the pipe and the fluid in order to maintain safe operating conditions.

A61L 27/44
PCT/CO2011/000001BRICEÑO TRIANA, Juan CarlosBRICEÑO TRIANA, Juan Carlos
The invention relates to a method comprising the mechanical and chemical treatment of the small intestine of a warm-blooded vertebrate, in order to remove the mucous, serous and muscular coats and to obtain the remaining submucous coat. In short, the jejunum portion of the small intestine is obtained from a recently deceased warm-blooded vertebrate and is stored at 4°C in 0.9% saline solution. Subsequently, longitudinal scraping is performed for the initial removal of the mucous coat and it is then washed until clean. The small intestine is cut longitudinally and both surfaces are scraped in order to remove the remaining mucous coat and the muscular and serous coats, until a translucent white membrane is obtained. This is then submerged in 0.9% saline solution or distilled water and washed for 30 to 120 minutes until the blood residues disappear, constantly stirring same and changing the water every 20 minutes. Scraping is performed once again in order to eliminate the last remanents of the serous, muscular and mucous coats. It is then exposed to a mixture comprising 0.5% sodium hypochlorite and 0.5% hydrogen peroxide for 15 to 40 minutes in order to eliminate the remaining cells, constantly stirring same and observing that no obvious structural changes occur. It is washed with a phosphate buffer solution for 15 minutes, stirring constantly, and subsequently washed with 0.9% saline solution or distilled water. The membrane obtained is shaped according to use. The membranes can be used individually or to form an aggregate of multiple stacked membranes depending on the desired strength and the membranes can be given particular shapes. Following shaping, the membranes are dehydrated by means of exposure to a laminar sterile air flow. The entire method must be carried out in maximum asepsis conditions at ambient temperature. The membranes must be sterilised prior to implantation in a living organism. Said membranes can be used in maxillofacial surgery, reconstructive and plastic surgery, cardiovascular surgery, gastroenterology and urology, inter alia.
