20080295392 | Method for recycling and exploitation of the glycerin obtained in the production of biodiesel - A method to exploit the glycerin obtained as a by-product of the industrial process to produce biodiesel inside or out of the industrial production unit, providing a reduction in the environmental liability that may be caused by an excess in the production of glycerin that cannot be exploited for industrial use. The referenced method uses recycling of the glycerin obtained through industrial process to produce biodiesel, using a process basically consisting of four stages: a) extracting glycerin produced as a by-product of the industrial process for producing biodiesel; b) hydrogenation of said n-propanol glycerin, c) recycling of the n-propanol thus obtained to be added to a mixture of alcohols; and d) transesterfication of the n-propanol mixture added to the alcohol mixture, together with raw material triglycerides from renewable sources in order to obtain biodiesel. The referenced recycling of the n-propanol stream provides a reduction in the amount of the alcohol mixture necessary for the industrial process to produce biodiesel, consequently reducing operational costs. | 12-04-2008 |

20140121408 | OXIDATIVE CATALYTIC PROCESS FOR THE SYNTHESIS OF LACTIC ACID - Current industrial processes for the production of lactic acid are fermentative, using lactic bacteria which require large volumes and create large quantities of liquid residue which need to be treated. Chemical literature also describes the use of reaction systems with homogeneous catalysis, which also pose problems which in turn impact our costs, owing to the increased requirements in terms of the control of the process and the type of reactor necessary. Therefore, the process used thus far, carried out in hydrogenolysis, isomerisation and oxidation are defective, owing to the significant formation of sub-products, mainly pyruvic acid and acetic acid and the low yield of lactic acid. | 05-01-2014 |

20140155651 | LACTIC ACID DIRECT SYNTHESIS PROCESS - This invention concerns a process for obtaining lactic acid in a single stage by direct oxidation in an aqueous medium of 1,2-propanediol in the presence of a mixture of heterogeneous catalysts, in conditions of low temperature and low pressure. The reaction takes place in the presence of oxygen and a mixture of heterogeneous catalysts, consisting of a first catalyst of noble metal supported in metallic oxide, and a second basic solid catalyst. The mixture of catalysts is easily recovered by filtration at the end of the process, to be reused. The lactic acid is obtained directly, with selectivity between 50% and 97%. | 06-05-2014 |

20130138274 | Flight Control System Mode And Method Providing Aircraft Speed Control Through The Usage Of Momentary On-Off Control - A longitudinal control law is designed to optimize the flying qualities when aircraft is set to approach configuration, i.e. when the flap lever is set to the landing position and landing gears are locked down. Under such circumstances, the effort of trimming the aircraft speed can be extremely reduced by the usage of a momentary on-off switch or other control in the sidestick, instead of or in addition to a conventional trim up-down switch, making easier the task of airspeed selection by the pilot. This control law provides excellent handling qualities during approach and landing, with the benefit of not needing or using radio altimeter information in safety-critical applications. | 05-30-2013 |

20090099542 | NONWOVEN WEB MATERIAL CONTAINING A CROSSLINKED ELASTIC COMPONENT FORMED FROM A LINEAR BLOCK COPOLYMER - A nonwoven web material that contains an elastic component is provided. The elastic component contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic component that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks. | 04-16-2009 |
20130126070 | Nonwoven Composite Containing an Apertured Elastic Film - An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing the film through a nip to bond the film to the nonwoven web material(s). Concurrent with bond formation, apertures are also formed in the elastic film. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Aperture and bond formation are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, bonding pattern, degree of film tension, bonding conditions, etc. | 05-23-2013 |

20090325448 | Elastic Composite Containing a Low Strength and Lightweight Nonwoven Facing - An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction (“CD”) is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing. In certain cases, it may be desirable to position the layer between two elastic layers so that the strength-enhancing layer does not substantially contact the nonwoven facing. In this manner, the strength-enhancing layer may avoid substantial damage during the lamination process. | 12-31-2009 |

20090325447 | Elastic Composite Formed from Multiple Laminate Structures - An elastic composite formed from a laminate that contains an elastic film and a lightweight nonwoven facing having a low strength in the cross-machine direction (“CD”) is provided. Due to the low strength of the facing, it is desirable that the elastic film have a sufficient thickness and weight to enhance the strength of the resulting composite. Unfortunately, the ability to join an elastic film to such a lightweight nonwoven facing becomes increasingly difficult as the thickness of the film increases. In this regard, the present inventors have discovered that a second laminate may be employed in the elastic composite that is formed from a thermoplastic film and nonwoven facing to impart increased strength to the composite. The film and facing of the second laminate may be formed from the same or different materials than the film and facing of the first laminate. Regardless, the laminates are positioned so that the elastic and thermoplastic films are in a face-to-face relationship. Through selective control over the polymer content and thickness, the present inventors have discovered that the elastic and thermoplastic films may be readily joined together under light pressure, even at ambient temperature conditions. This avoids the application of a substantial amount of heat used in conventional calender bonding processes, which can otherwise damage the film, and also minimize the need for costly adhesives. | 12-31-2009 |
