| 20110293404 | Submerged Hydroelectric Turbine Having Self-Powered Bearing Lubricant Circulation, Filtering, and Cooling System and Auto-Adaptive Pressure-Compensation System - An underwater hydroelectric turbine comprises a turbine housing having an inlet and an outlet, a central shaft extending axially inside the turbine housing, a self-contained, sealed front bearing unit for rotationally supporting a front end of the central shaft, and a self-contained, sealed rear bearing unit for rotationally supporting a rear end of the central shaft. The front bearing unit and the rear bearing unit each comprises a self-powered lubricant circulation system that draws a fraction of the mechanical power from rotation of the central shaft to circulate lubricant through each respective bearing unit. The turbine may have an equilibrium chamber for automatically balancing lubricant pressure inside a lubricant-containing chamber of the bearing chambers with ambient water pressure outside the bearing housing. | 12-01-2011 |

| 20100327591 | Kinetic Energy Recovery Turbine - The invention consists of developing an environmentally friendly new energy converter using light weight material. The energy converter shall be fully submersed in running undercurrents waters and have high overall efficiency ratio. The energy converter consists of, among other things, eliminating the in-line electric generator and substitute it with peripheral electro-magnetic coupling device, attached to the runner tip from inside and surrounding the energy converter housing from outside. The energy converter electric brushless circuits and winding must be totally sealed from water, using new sealing techniques and shall be also electrically isolated as well. The energy converter allows extracting energies from undercurrents with large frequency and voltage ranges. | 12-30-2010 |

| 20100008480 | Universal Internet Telephone System - There is described a method for setting up a call over the Internet between a Web-based phone and a phone device. The Web-based phone is loaded on a Java-enabled computing device. The call involves a Web application hosted on an external server capable of communication with a SIP Server on which the Web-based phone is pre-registered. Upon request from the computing device, the external server sends an HTTP message to a SIP Switch which in turn forwards a SIP NOTIFY message to the computing device through the SIP Server. The Web-based phone then pops up on the computing device and the call initiation can be confirmed. There is also described a platform independent Web-based phone as well as a Web application for auto-populating a contact directory from contacts on a social networking Web site. | 01-14-2010 |

| 20110182990 | NANOCOMPOSITE HYDROGEL AND METHOD FOR PREPARING IT, FOR INDUSTRIAL AND MEDICAL APPLICATIONS - Nanocrystalline cellulose (NCC) is employed as the cross-linker and reinforcement domain for developing nanocomposite hydrogels possessing high strength and improved diffusion property; the resulting nanocomposite hydrogels are shown to have high mechanical properties, reversible swelling ability, and are biodegradable and biocompatible; the approach relies on free radical polymerization to form the hydrogels using a variety of hydrophilic vinyl monomers. These hydrogels are suitable for developing highly absorbent hygiene products, as well as for applications in medicine, engineering materials and sensors. | 07-28-2011 |
| 20110196094 | NANOCOMPOSITE BIOMATERIALS OF NANOCRYSTALLINE CELLULOSE (NCC) AND POLYLACTIC ACID (PLA) - A new approach is conceived for the development of sustainable biomaterials comprising nanocrystalline cellulose (NCC) and polylactic acid (PLA) nanocomposites. The invention deals with advancing a method based on in situ ring opening polymerization of L-lactide in the presence of NCC particles to form NCC-PLA supramolecular nanocomposite materials. This material is hydrophobic and compatible with a wide range of synthetic and natural polymers. NCC-PLA nanocomposites have enhanced functionality (e.g. gas barrier), rheological and mechanical performance, as well as dimensional stability (i.e. less hygroexpansivity) relative to PLA. They are made from entirely renewable resources, and are potentially biocompatible as well as recyclable. NCC-PLA supramolecular nanocomposites can be suspended in most organic solvents or dried to form a solid substance. They can be processed using conventional polymer processing techniques to develop 3-dimensional structures, or spun into fibres, yarns or filaments. | 08-11-2011 |
| 20110201755 | THERMOPLASTIC NANOCOMPOSITE MATERIAL BASED ON NANOCRYSTALLINE CELLULOSE (NCC) - A green approach for the development of nanocomposite materials comprising nanocrystalline cellulose (NCC) and appropriate vinyl polymers is conceived. The approach deals with the in-situ graft co-polymerization of hydrophobic vinyl monomers, such as vinyl acetate and methyl methacrylate, onto the NCC surface in an aqueous medium. The resulting material is significantly more hydrophobic and thermally stable than the starting NCC. The nanocomposite material can be suspended in appropriate solvents, dried and moulded with other materials using conventional polymer processing techniques to develop yet new materials with new characteristics. These nanocomposites have wide ranging applications from industrial to medical use. | 08-18-2011 |
| 20110308750 | HYDROPHOBIC LIGNOCELLULOSIC MATERIAL AND PROCESS THEREFOR - A method is conceived for producing hydrophobic lignocellulosics based on the graft copolymerisation of vinyl-type monomers onto the lignocellulosic backbone initiated by a redox couple initiator in aqueous medium. The green modification process can be carried out on any lignocellulosic material, for example, chemical, chemi-thermomechanical or thermo-mechanical pulps, bleached or unbleached. The technology disclosed in this invention yields individual lignocellulosic entities, for instance, hydrophobic pulp fibres, that can be used in combination with other fibres or polymers to produce nonwoven fibrous materials or composites. A significant aspect of the invention is that the modified lignocellulosic material possesses an efficient hydrophobic barrier and minimum interfacial energy to generate optimum adhesion when introduced to polymer resins. Hydrophobic lignocellulosics can have wide applications in products requiring high dimensional stability and excellent adhesion as in fibre-based packaging, decorative laminates, furniture and non-structural biocomposites. | 12-22-2011 |

| 20110248214 | INORGANIC MESOPOROUS MATERIALS WITH CHIRAL NEMATIC STRUCTURES AND PREPARATION METHOD THEREOF - The present invention describes a composition and a method for producing mesoporous silica materials with a chiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose (NCC) to give a material of inorganic solid with cellulose nanocrystallites embedded in a chiral nematic organization. The NCC can be removed to give a stable porous structure that retains the chiral organization of the NCC template. The new materials may be obtained as iridescent free-standing films with high surface area. Through control of the reaction conditions, the colour of the films can be varied across the entire visible spectrum. These are the first materials to combine mesoporosity with long-range chiral ordering that leads to photonic properties. Examples of possible applications of the materials are: lightweight reinforcement materials, low k dielectric materials, tunable reflective filters, adsorbents, stationary phases for chromatography of chiral or achiral substances, supports for catalysts (e.g., for asymmetric synthetic transformations), and as a template to generate other new porous materials (e.g., porous carbon or porous metals), preferably with chiral nematic structures. | 10-13-2011 |
