Title: Emulsions aqueuses stables de silanes non polaires, a dimension particulaire constante
Inventor: GEE RONALD PAUL
IPC: C09K23/42
Filed: 1999-11-19
Abstract: L'invention concerne une émulsion aqueuse de silane comprenant un système émulsifiant empêchant l'augmentation de la dimension particulaire, avec le temps. L'émulsifiant contient un premier tensioactif qui empêche les particules de coalescer, par répulsion ionique entre les particules et un tensioactif. Les doses de chaque tensioactif présentes dans le système émulsifiant sont suffisantes pour former une monocouche extérieure mixte, laquelle entre en contact avec la phase aqueuse, ainsi qu'une seconde monocouche intérieure, constituée essentiellement d'un co-tensioactif insoluble dans l'eau. La monocouche mixte résulte de la combinaison des deux tensioactifs. La double couche de tensioactifs constitue une barrière empêchant la diffusion du silane dans la phase aqueuse, minimisant ainsi la diffusion du silane hors de la particule.

Title: Method for simulating a characteristic of a physical system
Inventor: WATTS JAMES W III
IPC: G01V1/30
Filed: 2000-03-15
Abstract: A method is provided for simulating at least one characteristic of a physical system. The physical sytem is discretized into a plurality of volumetric cells (201-215) having boundaries therebetween. An initial estimate of state variables is assigned for each cell. For each cell, linear equations are constructed relating its state variables to the state variables of cells adjacent to it. A transportability value is associated with each boundary and the boundaries are ranked corresponding to descending transportability values. The boundary rankings are used to construct topologically one-dimensional strings of cells (50, 51). A matrix equation for each string is constructed by assembling the linear equations associated with the cells for each string. Improved estimates of the state variables of the cells are determined by solving the matrix equations. These state variables are then used to simulate at least one characteristic of the physical system.
