20080233054 | DENTAL ANTI-HYPERSENSITIVITY COMPOSITION AND METHOD - The present invention relates to compositions and methods for calcifying dental tissue, e.g., preventing or treating dental hypersensitivity. An oral composition of arginine bicarbonate and calcium carbonate promotes the formation of dentinal tubule plugs aided by combining calcium and phosphate in the fluid. In a specific example, an arginine bicarbonate/calcium carbonate mixture blocked dentinal tubules in a model system. In addition to treating dentinal sensitivity, the compositions and methods of the invention provide for calcifying exposed tooth pulp, calcifying the base or all of a pit or fissure in a tooth, and treating a carious lesion. | 09-25-2008 |

20100258659 | METHOD OF PROCESSING NEPHELINE SYENITE POWDER TO PRODUCE AN ULTRA-FINE GRAIN SIZE PRODUCT - The method of converting nepheline syenite particulate feedstock with a grain size profile to an ultra-fine grain finish product for subsequent commercial use, the ultra-fine grain final product has a maximum grain size of less than about 6 microns. The method comprising: providing a dry feedstock with a controlled maximum particle size greater than about 20 microns; grinding the feedstock in a dry state by passing the feedstock vertically downward through a continuous, high-speed stirred ball mill whereby the feedstock is ground into an intermediate powder having a drastically reduced grain size profile than the grain size profile of the feedstock; and passing the intermediate powder from the mill through an air classifier using a rapidly moving high speed air stream moving along a given path to convey the ultra-fine grain product along the path and from the classifier and to allow coarse particulate material including particles larger than the ultra-fine product to be separated and then expelled from the classifier. | 10-14-2010 |

20110256214 | SINGLE-TIME VACCINES - The invention is related to the field of vaccines. The technical objective is to obtain novel unitemporal therapeutic and prophylactic vaccines (single time vaccination strategy) using simultaneously one or more mucosal doses and one parenteral dose where the use of potent mucosal adjuvants are essential, preferable the Cochleate (AFCo I, Adjuvant Finlay Cochleate 1). The incorporation or co-administration by parenteral and mucosal routes of non-related PL antigens (heterologous), and/or the additional use of delivery systems like Aluminum, Chitosan or oil/water emulsions by parenteral application is also included in this invention. The induction of cellular immune responses than including systemic specific IgG and secretory specific IgA is obtained with at least two simultaneously doses. So, this unitemporal strategy is applicable to obtaining new unique or multiples vaccines (several mucosal vaccine antigens with the corresponding parenteral combine vaccine) in the pharmaceutical industry which permit to increase vaccine coverage and reduce the time-cost of vaccine campaigns. | 10-20-2011 |

20130264247 | PROCESS OF REDUCING VISCOSITY OF HEAVY CRUDE OIL BY REMOVAL OF ASPHALTENE USING A PRECIPITATING AGENT - A process and system for reducing the viscosity of heavy and extra heavy crude oils, and more particularly to a process for reducing the viscosity of heavy and extra heavy crude oils by means of total or partial oil deasphalting using a precipitating agent in order to obtain an upgraded crude oil of lower viscosity that can be pumped without the use of diluents. The upgrading also includes a reduction in metals and sulfur associated with asphaltene removal. The process consists of relatively simple equipment such as static mixers and stirred tanks and operation temperature is low and pressure is moderate. | 10-10-2013 |
