20160120764 | BISGMA-FREE ORTHODONTIC ADHESIVES - 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. The prepared adhesives with TMPTMA are photopolymerizables, thereby providing enough time to the operator to place the appliance in proper position, it is easy to handle, capable of supporting orthodontic biomechanics, has low elastic modulus, enables transitions of heavy arches reducing the risk of involuntary detachment of the appliances, have low viscosity, penetrates on both the brace retentions as those made with acid etching on enamel surface. Presenting adhesion to both the base of the attachments as well as to the enamel, its film thickness is minimal and does not alter the prescription system. When the appliance is removed at the end of the treatment, it does not cause structural damage to the enamel because the adhesive remains on the enamel and can be removed easily with a rotary instrument. | 05-05-2016 |
20150225351 | PROCESS TO OBTAIN MIXTURES OF IMIDAZOLINES AND CORROSION INHIBITORS FROM COFFEE WASTE - The biphasic extraction from coffee waste without a prior drying process, to obtain coffee oil, which is transesterified with KOH catalyzed methanol to produce mixtures of glycerol free methylic esters, also known as coffee oil biodiesel, which is subjected to an aminolysis reaction with aminoethylethanolamine (AEEA) by heating to 140-160° C. at atmospheric pressure with a subsequent dehydration reaction at the same temperature but at a reduced pressure of 200 to 300 mmHg, in order to achieve cyclization of the intermediary amides into the corresponding imidazolines. Alternatively process, coffee oil can be submitted to the same aminolysis procedure with aminoethylethanolamine (AEEA) at 140 to 160° C. and atmospheric pressure with a subsequent dehydration reaction at the same temperature but at a reduced pressure of 200 to 300 mmHg, to produce imidazolines that contain the residual glycerol of the original triglycerides. | 08-13-2015 |

20140238162 | SPEED REDUCER - 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 case of the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts when these are aligned 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 the contact is rolling, friction is therefore low and as a consequence, efficiency is high, so high indeed that it allows this invention also to serve as an amplifier. | 08-28-2014 |
20140205722 | COMPOSITION OF SOLID LIPID NANOPARTICLES FOR THE LONG-TERM CONSERVATION OF FRUITS, VEGETABLES, SEEDS, CEREALS AND/OR FRESH FOODSTUFFS USING A COATING - 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. | 07-24-2014 |
20130205942 | CYCLOIDAL TRANSMISSIONS - 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. | 08-15-2013 |
