Title: Confinement magnetique et electrostatique de plasma dans une configuration a champ inverse
Inventor: ROSTOKER NORMAN
IPC: G21B1/05
Filed: 2002-02-01
Abstract: Système et procédé pour confiner du plasma et former une topologie magnétique de configuration à champ inversé (FRC), dans laquelle des ions plasma sont confinés magnétiquement dans des orbites stables non adiabatiques. De plus, les électrons sont confinés électrostatiquement dans un puits d'énergie profond, produit par accordage d'un champ magnétique appliqué de façon externe. Le confinement électrostatique d'électrons mis en oeuvre simultanément avec le confinement magnétique d'ions permet d'éviter un transport anormal et facilite le confinement classique des électrons et des ions. Dans cette configuration, ions et électrons peuvent présenter une densité et une température adéquates de sorte qu'ils fusionnent par force nucléaire lors des collisions, libérant ainsi de l'énergie de fusion. De plus, les plasma à combustible libéré par fusion pouvant être utilisés dans le système et le procédé de confinement présentés ne sont pas limités aux seuls combustibles neutroniques, mais incluent aussi avantageusement des combustibles avancés.

Title: Improved electron transfer agents in well acidizing compositions and methods
Inventor: BREZINSKI MICHAEL M
IPC: C09K8/74
Filed: 2002-03-07
Abstract: An acidizing composition and a method of acidizing a hydrocarbon bearing subterranean formation in the presence of ferric ions are provided.
