20100107478	Oxazolidines derived from polyalkyl or polyalkenyl n-hydroxyalkyl succinimides, obtainment process and use - The present invention relates to oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides, the obtainment process thereof, and their use to prevent and control the formation of deposits in internal combustion engines, primarily in formulations of additives to be applied to hydrocarbon fuels.	05-06-2010
20110162558	Formulations comprising an asphaltene-dispersing/inhibiting additive based on oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides - The present invention relates to formulations of asphaltenes' inhibitor-dispersant additives based on oxazolidine derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides. Said formulations can contain inert organic solvents, preferably including: toluene, mixtures of xylene, o-xylene, p-xylene, kerosene, turbo-fuel; or inert hydrocarbon solvents having boiling points within the range of gasoline and diesel; or inert hydrocarbon or organic solvents having a boiling point within a range from 75 to 300° C. The ratio in weight of inert organic solvents to additive that prevents and controls the precipitation and deposition of asphaltenes ranges from 1:9 to 9:1, preferably from 1:3 to 3:1.	07-07-2011

20110303385	AUTOMATED SYSTEM FOR IMPROVED COOLING OF ALUMINUM CASTINGS IN SAND MOLDS - An improved and efficient method and apparatus for convective cooling of cast sand molds containing molten metal, utilizing vertically-arrayed cooling stations (preferably arranged on a plurality of shelves inside a housing enclosure for temporarily storing said sand molds during their cooling from a molten temperature level to a lower solidification temperature. A draft of cooling air is circulated through said stations in said housing whereby the time for solidifying the molten metal in said cast sand molds is reduced as compared with passive air cooling of said molds. Robot means are provided for moving hot sand molds from a feeding port in said housing to said shelves and for moving cooled sand molds from said shelves to a delivery port in said housing. The robot means is programmed so that the time period of each mold is maintained within said housing according to the individual time required for the solidification of the metal in such individual mold (based on empirical data for typical solidification required for the given individual cast sand mold package or based on other appropriate discernible physical property attributable to achieved solidification).	12-15-2011
