Publication number: 20160120764Abstract: Three adhesives formulated with Trimethylolpropane Trimethacrylate (TMPTMA) that do not contain BisGMA were developed, whereby the mutagenic and teratogenic risk by the release of bisphenol A is eliminated, and presented a better performance compared to the three commercial adhesives prepared with BisGMA (Adhesive A, Adhesive C and Adhesive B). The invention provides an adhesive used in one-step and provides a system which is formed by a primer and a slurry. The adhesives of the invention were compared with two commercial controls. They were physically characterized by assessing: hardening time, adhesion stress, elastic modulus, sorption and solubility at different pHs (6.8 and 7.7); by the obtained values premature detachments, white lesions below the appliance and microfiltration are avoided; its fluidity, film thickness were evaluated and were compared with those obtained from the three commercial adhesives. Storage stability and thermogravimetric analysis were assessed.Type: ApplicationFiled: June 17, 2014Publication date: May 5, 2016Applicant: UNIVERSIDAD NACIONAL AUTONOMA DE MEXICOInventors: Eira LOPEZ PALACIOS, Carlos Andres ALVAREZ GAYOSSO, Gabriel SAEZ ESPINOLA

Patent number: 9234570Abstract: This invention refers to a speed reducer made up of a chain carrying nuts and of a screw, i.e., a ball screw in the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts on one of the straight stretches of the chain. The ball screw, or the roller screw, can be almost as long as the distance between the centers of the output sprockets on which the chain is mounted. Given these features and because the nuts wrap the ball screw, or the roller screw in a great surface, the load capacity is high. Given that in both embodiments there is rolling contact, friction is low and, as a consequence, efficiency is high, and this allows the present invention to serve also as an amplifier.Type: GrantFiled: January 23, 2014Date of Patent: January 12, 2016Assignee: Universidad Nacional Autonoma de MexicoInventors: Enrique Jaime Chicurel Y Uziel, Filiberto Gutierrez Martinez

Patent number: 8979698Abstract: The present invention refers to a conventional spur gear transmission or magnetic gear transmission, with a cycloidal configuration. The magnetic gears include contact points such that the mobile gear rolls on the fixed gear. Alternatively, a balance wheel is incorporated, which generates a centrifugal force opposite to the one associated with the mobile gear, of equal magnitude and on the same plane as this latter one, thereby completely eliminating the unbalancing of the mechanism. The balance wheel is mounted on the high-speed shaft in a manner similar to the mobile gear, and has the freedom to displace itself radially through centrifugal effect in the opposite direction to the eccentric position of the center of the mobile gear until it presses against a fixed track over which it rolls, concentric with the fixed gear with an equal force, opposite and collinear with that produced by the mobile gear.Type: GrantFiled: February 6, 2013Date of Patent: March 17, 2015Assignee: Universidad Nacional Autonoma de MexicoInventors: Ricardo Chicurel Uziel, Luis Alberto Vazquez Perez, Gabriel Ascanio Gasca

Publication number: 20140205722Abstract: The invention relates to a composition of solid lipid nanoparticles taking the form of a nano-coating for natural fresh foodstuffs, such as seeds, cereals, fruits or vegetables, preferably fresh fruits and vegetables which are coated by means of fluidization, immersion or spraying. According to the invention, the composition comprises: (a) solid lipids or wax, (b) emulsifying stabilizing agents, and film-forming materials in an aqueous dispersion or solution. The inclusion of a submicronic lipophilic system in aqueous dispersion allows the application of the composition to be easily controlled since it is a fluid system with low viscosity, which is advantageous in that it can be applied easily and uniformly and provides improved coating properties, such as sheen, mechanical strength and gas permeability inter alia.Type: ApplicationFiled: March 30, 2012Publication date: July 24, 2014Applicant: UNIVERSIDAD NACIONAL AUTONOMA DE MEXICOInventors: David Quintanar Guerrero, Maria de la Luz Zambrano Zaragoza, Alfredo Alvarez Cardenas, Edmundo Mercado Silva

Patent number: 8717369Abstract: Opto-mechanical motion capture system for indirectly measuring the movement of bodies and objects, mainly focused on joints of flexible materials, or which have deformations, which makes difficult the instrumentation with rigid sensors such as potentiometers. This invention consists of an image acquisition device or camera and a visualization bed in which there is a series of transmission cables which convey to the visualization bed the movements generated in the flexible parts to be sensed. The camera is set in such a way that it is possible to capture the image of the transmission cables, enabling the determination of its displacement and thus of the sensed objects. The main object of this invention is to enable the measurement of the movements of the flexible parts of the human body in a simple, cheap and comfortable way for the user of the device.Type: GrantFiled: August 21, 2008Date of Patent: May 6, 2014Assignee: Universidad Nacional Autonoma de MexicoInventor: Hernando Ortefa-Carrillo
