Abstract: An anti-lumping agent for use with expandable polystyrene beads is disclosed.  The expandable polystyrene beads comprise a styrene or styrene derivative polymer in combination with a blowing agent, Typical blowing agents are C3-C6 hydrocarbons, with pentane being especially preferred. The anti-lumping agents include block copolymers formed from blocks of ethylene oxide and propylene oxide. Preferably, the copolymers have a number average molecular weight of from about 4,000 to 15,000, and a hydrophilic-lipophilic balance number of from about 16 to 29. The anti-lumping agents significantly reduce the lumping potential of the expandable polystyrene beads, especially when they are expanded to low densities of from about 1.5 to 0.75 lbs. per cubic foot, and more preferably to densities of from about 1.2 to 0.85.

Abstract: La présente invention concerne un lecteur optique comportant une source de lumière (3810) émettant la lumière via une fibre optique (3820) en direction d'une matrice de détection. La fibre optique comporte une surface réfléchissante (3822) et un diffuseur (3824). La surface réfléchissante renvoie la lumière (3815), directement ou indirectement, en direction du diffuseur, lequel diffuse la lumière en sortie de la fibre optique. La fibre optique comporte en outre une rainure réfléchissante renvoyant la lumière vers le diffuseur en direction de la surface réfléchissante. Le diffuseur diffuse la lumière en direction d'un objet qui renvoie la lumière sur la matrice de détection. L'objet considéré est notamment un code à barres, du papier monnaie, ou tout autre objet à passer au lecteur optique. Le diffuseur peut être un diffuseur variable.

Abstract: L'invention concerne un procédé d'inertisation servant à éviter et/ou à éteindre des incendies dans un local fermé. Ce procédé consiste à introduire dans le local cible un gaz refoulant l'oxygène pour ajuster un premier niveau d'inertisation de base avec une teneur en oxygène réduite par rapport aux conditions naturelles et à continuer à introduire dans le local cible, de manière progressive en cas de besoin ou de manière soudaine en cas d'incendie, un gaz refoulant l'oxygène pour ajuster un ou plusieurs niveaux d'inertisation différents du premier, avec une teneur en oxygène à nouveau réduite. L'invention concerne en outre un dispositif pour mettre en oeuvre ledit procédé, comprenant un dispositif de mesure de la concentration d'oxygène dans le local cible ainsi qu'une source de gaz refoulant l'oxygène. L'objectif de l'invention est de créer un procédé d'inertisation et un dispositif pour mettre en oeuvre ledit procédé qui permettent de stocker, de manière simple et économique, le gaz d'extinction à fournir pour l'extinction d'incendies, sans devoir faire appel aux locaux habituellement prévus spécialement à cet effet.

Title: Active controlled bottomhole pressure system and method
Inventor: ARONSTAM PETER S
IPC: E21B4/02
Filed: 2002-09-19
Granted: 2008-02-19
Abstract: A wellbore drilling system has an umbilical that carries a drill bit in a wellbore. Drilling fluid pumped into the umbilical discharges at the drill bit bottom and returns through an annulus between the umbilical and the wellbore carrying entrained drill cuttings. An active differential pressure device (APD  device), such as a jet pump, turbine or centrifugal pump, in fluid communication with the returning fluid creates a differential pressure across the device, which alters the pressure below or downhole of the device. The APD  device can be driven by a positive displacement motor, a turbine, an electric motor, or a hydraulic motor. A controller controls the operation of the APD  device in response to programmed instructions and/or one or more parameters of interest detected by one or more sensors. A preferred system is a closed loop system that maintains the wellbore at under-balance condition, at-balance condition or over-balance condition.

Granted: 2011-05-31
Abstract: A method of manufacturing a component, in particular an aluminium electrowinning anode, for use at elevated temperature in an oxidising and/or corrosive environment comprises: applying onto a metal-based substrate layers of a particle mixture containing iron oxide particles and particles of a reactant-oxide selected from titanium, yttrium, ytterbium and tantalum oxides;  and heat treating the applied layers to consolidate by reactive sintering of the iron oxide particles and the reactant-oxide particles to turn the applied layer into a protective coating made of a substantially continuous reacted oxide matrix of one or more multiple oxides of iron and the metal from the reactant-oxide. The metal-based substrate comprises at its surface during the heat treatment an integral anchorage-oxide of at least one metal of the substrate. The anchorage-oxide anchors the multiple oxide matrix to the substrate by reacting with the iron oxide and/or the reactant-oxide to form an integral multiple bonding oxide of the metal of the integral anchorage-oxide and iron from the iron oxide and/or the metal of the reactant-oxide. The particle mixture can be applied in a colloidal and/or polymeric slurry.
